Answer:

minutes took to finish the race = 54 minutes

Step-by-step explanation:

It's known that:

[tex]speed = \frac{distance}{time}[/tex]

then:

[tex]time = \frac{distance}{speed}[/tex]

IN THE 1ST 10 MILES:

time = [tex]\frac{10}{25} = \frac{2}{5} = 0.4 hours[/tex]

IN THE 2ST 10 MILES:

time = [tex]\frac{10}{20} = 0.5 hours[/tex]

Hence, Overall time took to finish the race = 0.4 + 0.5 = 0.9 hours

time in minutes = 0.9 × 60 = 54 minutes


Another Solution:

Overall speed = [tex]\frac{S_1 + S_2}{2}[/tex], Where: S1: 1st speed, S2: 2nd speed

then:

speed = [tex]\frac{25 + 20}{2}= 22.5 mph[/tex]

Hence, time took = [tex]\frac{20}{22.5} = 0.9 hours = 54 minutes[/tex]

What is a staticistcal question musa can ask about the club

Answers

A statistical question will pose a problem with a potential range of solutions. 'How many hours does an average member of the club at Musa's school spend participating in club events each month?' is a statistical question that Musa might use to help him gather data about the club.

What exactly is a statistical question?

Only once varied data have been gathered can a statistical question be addressed. A statistical question is one that may be answered by gathering information, and there will always be variation in the information. Since there is no variability in the data used to answer the question, questions that can be answered by a single data point are not statistical questions. After data has been gathered and examined, the solution can give an interpretation of the data. Although there will be statistics for a non-statistical question, the outcomes won't change. There will be only one solution.

The following qualities should be included in a statistical question:

What is function?

In mathematics, a function is a relationship between two variables in which one variable (the independent variable) determines the value of the other variable (the dependent variable). It assigns a unique output value to each input value. Functions are commonly denoted as f(x), where x is the independent variable and f(x) is the dependent variable.

Here,

The relation ((0.5), (3-1), (1,3), (5,-5)) has three pairs of values: (0.5, 3-1), (1, 3), and (5, -5).

To plot this relation, you can plot each point on a coordinate plane. The first value in each pair represents the x-coordinate, and the second value represents the y-coordinate.

The relation ((-1,-4), (0, -1), (1, 2), (2, 5)) has four pairs of values: (-1, -4), (0, -1), (1, 2), and (2, 5).

To plot this relation, you can plot each point on a coordinate plane. The first value in each pair represents the x-coordinate, and the second value represents the y-coordinate.

The equation y = -2x represents a linear function with a slope of -2 and a y-intercept of 0.

To graph this function, you can plot any two points that satisfy the equation and draw a line passing through those points. For example, you can use the points (0, 0) and (1, -2).

To complete the function table for y = x - 3, you can substitute each value of x in the equation and solve for y.

For example, when x = -5, y = -5 - 3 = -8. Repeat the process for the other values of x.

To complete the function table for y = 4x + 4, you can substitute each value of x in the equation and solve for y.

For example, when x = -2, y = 4(-2) + 4 = -4. Repeat the process for the other values of x.

To complete the function table for y = -x + 6, you can substitute each value of x in the equation and solve for y.

For example, when x = -10, y = -(-10) + 6 = 16. Repeat the process for the other values of x.

To complete the function table for y = -2x - 5, you can substitute each value of x in the equation and solve for y.

For example, when x = -3, y = -2(-3) - 5 = 1. Repeat the process for the other values of x.

the basketball team sold t-shirts and hats as a fund-raiser. they sold a total of 23 23 items and made a profit of $ 246 $246. they made a profit of $ 10 $10 for every t-shirt they sold and $ 12 $12 for every hat they sold. determine the number of t-shirts and the number of hats the basketball team sold.

Answers

If basketball team sold total of 23, t-shirts and hats as a fund-raiser, then the number of hats sold is 8 and number of T-Shirts sold is 15.

Let us denote the number of t-shirts sold = "x',  and

let the number of hats sold be = "y".

So, a system of two equations to represent the information is written as:

The total-items sold at fund-raiser is = 23,

So,

⇒ x + y = 23      ...equation(1),

The total profit is = $246,

So,

⇒   10x + 12y = 246       ...equation(2)

Solving equation(1) for x,

We get,

⇒ x = 23 - y

Substituting value of "x" into equation 2,

We get,

⇒ 10 × (23 - y) + 12y = 246,

⇒ 230 - 10y + 12y = 246

⇒ 2y = 16

⇒ y = 8

So, the basketball team sold 8 hats.

Substituting this value into equation(1);

We get,

⇒ x + 8 = 23

⇒ x = 15

Therefore, the basketball team sold 15 t-shirts and 8 hats.

where r is the radius of the sphere.

the rate of decrease in diameter (d) when the diameter is 11 cm.

We can start by deriving the formula for the surface area over time.

[tex]dA/dt = d/dt(πd^2)[/tex]

With chain rules it looks like this:

dA/dt = 2πd (dd/dt)

where dd/dt is the rate at which the diameter decreases.

Knowing that dA/dt is given as [tex]-9 cm^2/min[/tex] (unfavorable due to reduced surface area), look for dd/dt at d = 11 cm.

Substituting these values ​​into the above formula yields:

-9 = 2π(11) (dd/dt)

Simplified, it looks like this:

dd/dt = -9/(22π)

dd/dt ≈ -0.041 cm/min (rounded to three decimal places)

Answers

(a) (i) 0.3174 = 31.74% probability of a defect

(ii) The expected number of defects for a 1,000-unit production run is 317.

(b) (i) 0.0026 = 0.26% probability of a defect

(ii) The expected number of defects for a 1,000-unit production run is 3.

(C) Reduces the process standard deviation and causes no change in the number of defects.

When the distribution is normal, we use the z-score formula.

In a set with mean  and standard deviation, the score of a measure X is given by:

         Z = X-μ /σ

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Question a:

We have that: μ = 10 and σ = 0.12

(i). Calculate the probability of a defect.

Less than 9.88 or greater than 10.12. These probabilities are equal, so we find one and multiply by 2.

Probability of less than 9.88:

This is the p-value of Z when X = 9.88. Thus,

  Z = X-μ /σ

⇒ Z = 9.88 - 10/0.12

⇒ Z = -1, has a p-value of 0.1587

⇒ 2× 0.1587 = 0.3174

This means 0.3174 = 31.74% probability of a defect

(ii)  Calculate the expected number of defects for a 1,000-unit production run.

The expected number of defects is 31.74% of 1000. So

0.3174*1000 = 317.4

Rounding to the nearest integer

The expected number of defects for a 1,000-unit production run is 317.

Question (b):

The mean remains the same, but the standard deviation is now

(i) Calculate the probability of a defect.

Less than 9.88 or greater than 10.12. These probabilities are equal, so we find one and multiply by 2.

Probability of less than 9.88:

This is the p-value of Z when X = 9.88. Thus,

   Z = X-μ /σ

⇒ Z = 9.88 -10/0.04

⇒ Z = -3

⇒ Z = -3, has a p-value of 0.0013

which means 2× 0.0013 = 0.0026

from which 0.0026 = 0.26% probability of a defect

(ii) Calculate the expected number of defects for a 1,000-unit production run. The expected number of defects is 31.74% of 1000. Thus,

⇒ 0.0026*1000 = 2.6

Rounding to the nearest integer

The expected number of defects for a 1,000-unit production run is 3.

(C) The advantage of reducing process variation, thereby causing problem limits to be at a greater number of standard deviations from the mean Reduces the process standard deviation and causes no change in the number of defects.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means.

Probability is a way to gauge how likely something is to happen. Several things are difficult to forecast with absolute confidence. With it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject since it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

we have, μ = 2.4, σ = 0.8

(a) z1 = (x1 - μ)/σ = (2 - 2.4)/0.8 = -0.5

z2 = (x2 - μ)/σ = (3 - 2.4)/0.8 = 0.75

P(2 < x < 3) = P(-0.5 < z < 0.75) = 0.4648

(b) P(x > 3) = P(z > 0.75) = 0.2266

(c) z = (1.7 - 2.4)/0.8 = -0.875

P(x < 1.7) = P(z < -0.875) = 0.1908, which is 19.08%.

Part C: Explain how closure under multiplication applies to your your dimension and area in Part A. (7 points)

Answers

Therefore, the expression that represents the area of the rectangle is A(x) = mnx² + (mc + bn)x + bc.

What is polynomial?

In mathematics, a polynomial is a mathematical expression consisting of variables (also known as indeterminates) and coefficients, which are combined using only the operations of addition, subtraction, multiplication, and non-negative integer exponents.

Here,

Part A:

Let's assume that the length of the rectangle is represented by the linear polynomial L(x) = mx + b, where m is the slope of the line and b is the y-intercept. Similarly, let's represent the width of the rectangle by the linear polynomial W(x) = nx + c, where n is the slope of the line and c is the y-intercept.

The area of the rectangle is given by multiplying the length and width of the rectangle, so we can express the area A(x) as:

A(x) = L(x) * W(x)

= (mx + b) * (nx + c)

= mnx² + (mc + bn)x + bc

Part B:

The degree of the polynomial A(x) is 2, which makes it a quadratic polynomial. The classification of the polynomial A(x) is that of a concave upward parabola. The degree of the polynomial is 2 because of the presence of the quadratic term mnx² in the expression for the area. The classification of the polynomial as a concave upward parabola is because the coefficient of the x² term is positive (i.e., mn > 0), and this causes the graph of the polynomial to curve upwards.

Part C:

Closure under multiplication means that if we multiply two numbers in a certain set, the result is always within that same set. In the context of the dimensions and area of a rectangle, closure under multiplication applies because if we multiply the length and width (which are both represented by linear polynomials), the resulting area (which is represented by a quadratic polynomial) is still within the same set of polynomial functions. Specifically, multiplying two linear polynomials results in a quadratic polynomial, and since polynomial functions are closed under multiplication, the resulting area polynomial is still a polynomial function. This means that the area of the rectangle can be represented by a single polynomial function, which is useful for various mathematical computations and applications.

Kim receives 4 stickers more than Jim. If Kim receives 20 stickers, What is the ratio of Kim’s stickers to Kim’s stickers? How many stickers must Kim receive if Jim gets 60 stickers?

Answers

Kim must receive 75 stickers if Jim gets 60 stickers.

1. Since Kim receives 4 stickers more than Jim, and Kim receives 20 stickers,

we can determine the number of stickers Jim receives:
Jim's stickers = Kim's stickers - 4
Jim's stickers = 20 - 4
Jim's stickers = 16
2. The ratio of Kim's stickers to Jim's stickers is:
Kim's stickers : Jim's stickers
20 : 16
3. To simplify the ratio, divide both numbers by their greatest common divisor (4):
(20/4) : (16/4)
5 : 4
So, the ratio of Kim's stickers to Jim's stickers is 5:4.
4. If Jim receives 60 stickers, we can determine how many stickers Kim must receive using the ratio 5:4:
4 units = 60 stickers (Jim's)
1 unit = 60 stickers / 4
1 unit = 15 stickers
Since Kim has 5 units in the ratio:
Kim's stickers = 5 units * 15 stickers/unit
Kim's stickers = 75 stickers.

Step-by-step explanation:

The surface area is the sum of the lateral and base areas

Since the given figure is a cube (all sides and walls of a cube are equal), instead of finding its surface area the harder way, we can find the area of one side and multiply it by the number of sides a cube has (which is 6):

[tex]a(surface) = 3 \times 3 \times 6 = 54 \: {ft}^{2} [/tex]

Answer: 54 ft²

Step-by-step explanation: The side of a cube is given to be 3ft

We know the formula of the surface area of a cube is: 6A²

putting the value of side in the formula gives

6x(3)²=54 ft²

The surface area of the right rectangular prism is 87.88 square units.

The surface area of ​​a rectangle is the total area or area of ​​six faces. A prism is a solid with straight parallelogram sides and a base of the same polygon. There are many types of prisms such as triangular prism, square prism, cartesian prism, penta prism, and hexagonal prism.

Given that:

from the set of information :

Length(l) = 5.2

Breadth (b) = 2.6

Height(h) = 3.9

Area of the rectangular prism = 2(lb + bh + lh)

                                                 = 2(5.2×2.6 + 2.6×3.9 + 3.9×5.2)

                                                 = 2(43.94)

The null hypothesis (often denoted H0)[1] is the claim that no relationship exists between two sets of data or variables

being analyzed. The null hypothesis is that any experimentally observed difference is due to chance alone, and an

underlying causative relationship does not exist, hence the term "null". In addition to the null hypothesis, an alternative

hypothesis is also developed, which claims that a relationship does exist between two variables.

The null hypothesis is the actual hypothesis being tested and it can never be accepted based on a single statistical

a boat is tied with a rope to a dock that is 12 feet tall. along the water, the boat is 16 feet from the dock. how long is the rope connecting the boa

Answers

Answer:

Step-by-step explanation:

dock is 12 ft tall

boat is 16 ft from dock

how long is the rope?

The dimensions form a right tringle.

Use Pythagorean,

a² + b² = c²

12²  +  16² = c²

144 +  256 = c²

400 = c²

√400 = √c²

20 = c

The rope is 20 ft long.

The length of the rope connecting the boat to the dock is approximately 20 feet. This can be answered by the concept of Pythagorean theorem.

To calculate the length of the rope, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the rope is the hypotenuse, and the distance between the boat and the dock (16 feet) and the height of the dock (12 feet) are the other two sides. So we have:

Rope length² = 16² + 12²

Rope length² = 256 + 144

Rope length² = 400

Rope length = √400 = 20 feet

Therefore, the length of the rope connecting the boat to the dock is approximately 20 feet

Answers

The coordinate of point S given the midpoint is 1, 5)

Calculating the coordinate of point S

To find the coordinates of S, we first need to use the midpoint formula to find the coordinates of M.

The midpoint formula states that the coordinates of the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) are:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

We are given that the midpoint of ST is M = (4, -3), and we know the coordinates of T are T = (7, -11).

Using the midpoint formula, we can write:

M = ((x1 + 7)/2, (y1 - 11)/2)

Solving for x1 and y1, we get:

x1 + 7 = 2 * 4 = 8

y1 - 11 = 2 * (-3) = -6

x1 = 8 - 7 = 1

y1 = -6 + 11 = 5

Therefore, the coordinates of S are S = (1, 5).

Answers

Answer:

D. y = 1.5[tex](4)^{x}[/tex]

Step-by-step explanation:

There are a lot of ways to solve this, but here we will just use the simplest way is to put the number in for x and y to see if it is true or not, and that will be the correct answer.

Let's use the point (4, 384)

A. y = 4[tex](2)^{x}[/tex]

  384 = 4[tex](2)^{4}[/tex]

  384 = 64

This is not true, so A is wrong.

B. y = 3[tex](2)^{x}[/tex]

  384 = 3[tex](2)^{4}[/tex]

  384 = 48

This is not true, so B is wrong.

C. y = 4[tex](1.5)^{x}[/tex]

  384 = 4[tex](1.5)^{4}[/tex]

  384 = 20.25

This is not true, so C is wrong.

D. y = 1.5[tex](4)^{x}[/tex]

  384 = 1.5[tex](4)^{4}[/tex]

  384 = 384

This is true, so D is the answer.

Find the largest angle in quadrilateral PQRS, in degrees. ("<" =angle and the answer isn't 120)

Answers

So, the largest angle in quadrilateral PQRS is < 120 degrees.

A cyclic quadrilateral is what?

A quadrilateral that may be encircled by a circle is known as a cyclic quadrilateral.

Considering that,<P=3x , <Q=4x and <R=5x

∠P + ∠R = 180º            ∠Q + ∠S = 180º

Then we can write

3x+4x+5x+<S=360

12x+<S=360

<S=360-12x

We are aware that in a cyclic quadrilateral, the largest angle lies opposite the smallest angle.

Hence, in order to determine the largest angle, we must first determine the smallest angle.

P being the smallest angle leads us to believe that it is equal to x.

Therefore:

x+4x+5x+<s=360

10x+<s=360

<S=360-10x

therefore, Largest angle

- 10x < 360 - (10 * 24) = 120

So, the largest angle in quadrilateral PQRS is less than 120 degrees.

Answers

To find the number that 495 is 55% of, we can use the percent proportion or percent equation.

Using the percent proportion:

Part/Whole = Percent/100

Let x be the whole (or total) number we are looking for. Then:

495/x = 55/100

We can cross-multiply to solve for x:

49500 = 55x

Dividing both sides by 55:

x = 900

Therefore, 495 is 55% of 900.

Using the percent equation:

Percent * Whole = Part

Let x be the whole (or total) number we are looking for. Then:

55% * x = 495

We can divide both sides by 0.55 to solve for x:

x = 495 / 0.55

Simplifying:

x = 900

Therefore, 495 is 55% of 900.

Answer: 55 %

What is the measure of angle L? Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth. ​m∠L=​ °. LMN is a right triangle. M is a right angle. LM is equal to 18 inches, and LN is the hypotenuse and is equal to 60 inches.

Answers

The measure of angle L is approximately 48.59 degrees.

What is Pythagoras' Theorem?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

We can use trigonometry to solve for angle L. Using the Pythagorean theorem, we can find that the length of side MN is:

MN = sqrt(LN² - LM²) = √(60² - 18²) = √(3444) ≈ 58.66 inches

Now, using the definition of sine, we have:

sin(L) = MN / LN = 58.66 / 60

Taking the inverse sine (sin⁻¹) of both sides, we get:

L = sin⁻¹(58.66/60) ≈ 48.59 degrees

Therefore, the measure of angle L is approximately 48.59 degrees.
