im not sure if that is how you type it

Answer:

Step-by-step explanation:

a) The steering committee of 5 can be chosen from 15 members in 15 nCr 5 ways. Once the committee is chosen, the chair can be selected in 5 ways and the secretary can be selected in 4 ways (since the chair cannot also be the secretary). Therefore, the total number of different sets of committees (including officer selection) is:

15 nCr 5 * 5 * 4 = 3,003,600

b) Each of the 6 raffle prizes can be awarded to any of the 100 people, so there are 100 choices for the first prize, 99 choices for the second prize, and so on, down to 95 choices for the sixth prize. However, since the three $25 prizes are equivalent, we need to divide by 3! to account for the ways in which the $25 prizes can be arranged. Therefore, the total number of different raffle ticket winner selections is:

(100 * 99 * 98 * 97 * 96 * 95) / (3!) = 903,450,240,000

c) Since repeats are allowed and the code cannot begin with 0, there are 9 choices for the first digit and 10 choices for each of the remaining digits. Therefore, the total number of six-digit PIN codes that can be made is:

9 * 10^5 = 9,000,000

The best height he can jump is 2.5 meters. The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

It is believed that the four fundamental operations, often known as "arithmetic operations," adequately explain all real numbers. Division, multiplication, addition, and subtraction are the mathematical operations that come before quotient, product, sum, and difference.

We are given that Ivan Ukhov  jumps 2.4 metres which is 4% lower than the best height he can jump.

Let the best height be 'x'.

So, from the above information, we get

⇒ x - 0.04x = 2.4

⇒ 0.96x = 2.4                     (Using subtraction)

⇒ x = 2.5                             (Using division)  

Hence, the best height he can jump is 2.5 meters.

Answer:

Step-by-step explanation:

To express the difference in mean weights as a multiple of the MAD for both dog breeds, we can use the formula:

(difference in means) / (mean absolute deviation)

Let's plug in the values given in the problem:

(difference in means) = 13 - 11.5 = 1.5

(mean absolute deviation) = 2 + 1.8 / 2 = 1.9 (taking the average of the two MADs)

Now we can calculate:

(difference in means) / (mean absolute deviation) = 1.5 / 1.9 ≈ 0.7895

Therefore, the difference in mean weights between the two breeds is approximately 0.7895 times the average MAD for both breeds.

Rounding to the same number of significant digits as the measurement with the least number of significant digits (which is "350 ppm"), the expected CO₂ level by the end of 2030 would be 430 ppm.

Significant digits, also known as significant figures or sig figs, are the digits in a number that are considered to be accurate or meaningful. They represent the precision or reliability of a measurement or calculation.

In a number, all digits except for leading zeros are considered to be significant. For example, in the number 0.00456, there are three significant digits (4, 5, and 6), while the zeros before the 4 are not significant.

The rules for determining the number of significant digits in a number are:

All non-zero digits are significant.

Zeros between non-zero digits are significant.

Leading zeros are not significant.

To find the expected CO₂ level in the atmosphere by the end of 2030, we need to calculate the total increase in CO₂ levels from 2012 to 2030 and then add it to the 2012 CO₂ level of 396 ppm.

To calculate the total increase in CO₂ levels, we can use the following formula:

Total increase in CO₂ levels = rate of increase × time

where the rate of increase is 2.10 ppm per year and the time is the number of years from 2012 to 2030, which is 18 years.

Total increase in CO₂ levels = 2.10 ppm/year × 18 years = 37.8 ppm

Therefore, the expected CO₂ level in the atmosphere by the end of 2030 would be:

Expected CO₂ level = 2012 CO₂ level + total increase in CO₂ levels

Expected CO₂ level = 396 ppm + 37.8 ppm

Expected CO₂ level = 433.8 ppm

Rounding to the same number of significant digits as the measurement with the least number of significant digits (which is "350 ppm"), the expected CO₂ level by the end of 2030 would be 430 ppm.

To win the game, your team needs to score more than   [tex]35[/tex] points, which means: 3f + 7t > 35 three possible game-winning combinations are:

[tex]t = 5, f = 11: 3(11) + 7(5) = 63[/tex]

[tex]t = 6, f = 8: 3(8) + 7(6) = 62[/tex]

[tex]t = 7, f = 5: 3(5) + 7(7) = 56[/tex]

Each of these combinations would result in your team scoring more than 35 points and winning the game.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=).

For example, the argument [tex]"2x + 3 = 9"[/tex]  asserts that the phrase [tex]"2x + 3"[/tex]  equals the number "9." The purpose of equation solving is to determine the value or values of the variable(s) that allows the equation to be true.

Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation. [tex]"x2 + 2x - 3 = 0."[/tex]    Lines are utilised in many different areas of mathematics, such as  algebra, calculus, and geometry.

Let's let f be the number of field goals scored by your team and t be the number of touchdowns scored by your team.

a) To win the game, your team needs to score more than 35 points, which means:

3f + 7t > 35

We can simplify this inequality by dividing both sides by 1:

3f + 7t/1 > 35/1

3f + 7t > 35

b) Now, we need to find possible values for f and t that make this inequality true. Since we are looking for positive integer values for f and t, we can start by testing different values for t and solving for f:

If t = 5, then 3f + 7(5) > 35, so 3f > 0 and f > 0. Possible solutions are f = 1, f = 2, f = 3, and so on.

If t = 6, then 3f + 7(6) > 35, so 3f > 7 and f > 2. Possible solutions are f = 3, f = 4, f = 5, and so on.

If t = 7, then 3f + 7(7) > 35, so 3f > 14 and f > 4. Possible solutions are f = 5, f = 6, f = 7, and so on.

c) So, three possible game-winning combinations are:

[tex]t = 5, f = 11: 3(11) + 7(5) = 63[/tex]

[tex]t = 6, f = 8: 3(8) + 7(6) = 62[/tex]

[tex]t = 7, f = 5: 3(5) + 7(7) = 56[/tex]

Each of these combinations would result in your team scoring more than 35 points and winning the game.

The function f(x) = 2x³-3x² - 12x + 1 does not have any local maximum or minimum values over the interval [2, 3].

To find the local maximum and minimum of a function over a given interval, we need to find the critical points of the function within that interval and then apply the second derivative test to classify those critical points as local maximum or minimum.

To find the critical points, we first take the derivative of the given function:

f'(x) = 6x² - 6x - 12 = 6(x² - x - 2)

x = -1 or x = 2

Both of these critical points fall outside the given interval [2, 3]. Therefore, there are no critical points of the function within the interval [2, 3], and so there are no local maximum or minimum values of the function over this interval.

In other words, the function f(x) = 2x³-3x² - 12x + 1 does not have any local maximum or minimum values over the interval [2, 3].

Subtract 5° from both sides, getting the equation

7x = 140°

Isolate x by dividing both sides by 7

x = 20°

Substitute what we have for x into the equation "7x + 5°"

Answer: Let's call the scale factor between the two containers "k". Then, we know that the ratio of their surface areas is equal to the square of the scale factor:

(surface area of B) / (surface area of A) = k^2

We also know that the ratio of their volumes is equal to the cube of the scale factor:

(volume of B) / (volume of A) = k^3

We can rearrange the first equation to solve for k:

k^2 = (surface area of B) / (surface area of A) = 10478 mm^2 / 1550 mm^2 = 6.75

Taking the square root of both sides, we get:

k = sqrt(6.75) = 2.6 (rounded to one decimal place)

Now we can use the second equation to find the volume of container A:

(volume of B) - (volume of A) = 62160 mm^3

(k^3)(volume of A) - (volume of A) = 62160 mm^3

Simplifying and solving for the volume of A, we get:

volume of A = 62160 mm^3 / (k^3 - 1) = 62160 mm^3 / (2.6^3 - 1) ≈ 4477 mm^3

Therefore, the volume of container A is approximately 4477 mm^3.

The function has the maximum revenue of $348,480 with the increasing rate of $33.

The highest and smallest values of a function, respectively, can either be found inside a specific range or distributed throughout the entire domain. They are also sometimes referred to collectively as the function's extrema. The plural forms of a function's maximum and minimum are called maxima and minima, accordingly.

Given data:

The overall revenue is thus:

y = (36 - 0.50x)(9600 + 160x)

Differentiate with respect to x.

y ' = (-0.50)(9600 + 160x) + 160(36 - 0.50x)

y' = -4800 - 80x + 5760 - 80x

y' = 960 - 160x

To find x, put y' = 0

960 - 160x = 0

x = 960/160 = 6 (critical point)

Function is decreasing in interval - [6, +∞)

Increasing Function in interval - (-∞, 6]

Thus, the function has the maximum value at x = 6.

maximum revenue f(6):

f(6) = (36 - 0.50x)(9600 + 160x)

f(6) = (36 - 0.50(6))(9600 + 160(6))

f(6) = $348,480

Rate : 36 - 0.50(6) = $33

The function has the maximum revenue of $348,480 with the increasing rate of $33.

The equation of the line is 3y-5x=3 and the graph is attached.

Geometrically speaking, a line is a one-dimensional figure because it has length but no width. A group of points can be extended endlessly in opposing directions to form a line. Two points in a two-dimensional plane determine it. There are, however, additional ways to formulate the equation of a line in a two-dimensional coordinate system. The three most popular methods are the point-slope form, slope-intercept form, and general or standard form of the equation of a line. As its name suggests, the point-slope form combines a line point and a straight-line slope. The equations of infinite lines with a particular slope can be expressed, however when we specify that the line passes through a particular point, we get a singularity.

a) Since the temperature of the oven is decreasing by a percentage of its current temperature each minute, the function that best represents this situation is an exponential function.

b) Let T be the temperature of the oven in degrees Fahrenheit at time x minutes after it was turned off. The initial temperature of the oven was 450° F, and the temperature decreases by 10% each minute. This can be expressed as:

T = 450(0.9)^x

Therefore, the function that models the situation is:

f(x) = 450(0.9)^x

where f(x) is the temperature of the oven in degrees Fahrenheit x minutes after it was turned off.

The initial investment was approximately $2,603.88, which is option (b).

Probability is a measure of the likelihood of an event occurring.

where A is the final amount, P is the principal (initial investment), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time period in years.

In this case, we know that the final amount A is $3,820, the annual interest rate r is 5.5% (or 0.055 as a decimal), the interest is compounded 6 times a year (n = 6), and the time period is 7 years.

Coordinates are used to identify the position of an object on a two-dimensional grid or in three-dimensional space. They are usually written as pairs of numbers, separated by a comma.

1. We must deduct 2 from all of the y-coordinates of the vertices of the parallelogram ABCD in order to translate it two units down. Let's assume that the vertices' initial coordinates are A(a,b), B(c,d), C(e,f), and D. (g,h). The vertices will then have the new coordinates A'(a,b-2), B'(c,d-2), C'(e,f-2), and D' (g,h-2). To obtain the translated parallelogram, plot these new vertex points.

2. To move the rhombus EFGH 2 units to the left and 4 units down, we must deduct 2 from all of its vertices' x-coordinates and 4 from all of its y-coordinates. Let's assume that the vertices' initial coordinates are E(a,b), F(c,d), G(e,f), and H. (g,h). The vertices will then have the new coordinates E'(a-2,b-4), F'(c-2,d-4), G'(e-2,f-4), and H' (g-2,h-4). To obtain the translated rhombus, plot these additional vertices.

3.
