Find the value of x.

Answer:

D) 7.5%

Step-by-step explanation:

We can solve this through guessing and checking, or we can do this mathematically. We will try both approaches.

Mathematically:

We know that to get the extra $30 if we have $100, is a 30% interest. Now, since we have 4x 100, and these numbers are inversely proportional, we will need to divide 30 by 4. Doing this gives us 30/4 = 7.5, so the answer is 7.5%.

Guess and Check:

This way is a bit slower, but we will go through each answer and find how much money we would get from them. So, we would take our percent, change it to a number of that percent, considering we are taking it from 100, and multiply it by 4 since we have $400. We will get each of these respectively:

A) 3% = 3 * 4 = $12

B) 4.5% = 4.5 * 4 = $18

C) 6% = 6 * 4 = $24

D) 7.5% = 7.5 * 4 = $30

As you can see, D) gives us that extra $30, so the answer is D) 7.5%.

Hope this helped!

Answer:

C) g(x)=2(x+4)(x-7)

Step-by-step explanation:

g(x)=2x²-6x-56

g(x)=(2x+8)(x-7)

g(x)=2(x+4)(x-7)

Therefore, C is correct. You can expand to check your answer.

Answer: • The probability of a randomly selected test having a score higher than 4 is 0.15.

This is the correct interpretation of P(X > 4). P(X > 4) represents the probability of a randomly selected test having a score that is greater than 4. This is calculated by summing up the probability of all the scores that are greater than 4 in the distribution table.

Answer:

Your answer is about 36%.

Step-by-step explanation:

First you do 549-351 = 198.

You do this to find the amount of people supporting the home team.

Then you do 198/549 = 0.36065573770492.

Times this number by 100 and you have your answer of 36.065573770492%.

Answer:

36%

Step-by-step explanation: First, you need to find out what number of people supported the home team by finding the difference.

549-351=198

To turn the number of home team supporters into a percentage, you need to take the fraction [tex]\frac{198}{549} \\[/tex] and convert it to a decimal by division.

198/549=.3606557377

Round to the hundredths place

=.36

move the decimal, and you have your percentage

What is a right-angle triangle, exactly?

A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees. The combined angles of the other two are 90 degrees.

                         Perpendicular and the triangle's base make up the sides that the right angle is formed from. The hypotenuse, or third side, is the longest of the three. It is also known as the hypotenuse.

using the sine ratio in the right triangle and the exact value

  sin30° = 1/2, then

    sin30° = XY/XZ = XY/12 =  1/2  ( cross - multiply)

     2XY = 12  ( divide both sides by 2 )

        XY = 6

What is the image of ( 12 , − 4 ) after a dilation by a scale factor of 1/4 centered at the origin is (3, -1)

Transformation is the movement of a point in the coordinate plane. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease of a figure by a scale factor k. If the value of k > 1, then it is an enlargement but if k < 1, it is a reduction.

The point (12, -4) is dilated by a scale factor of 1/4 using the rule (x, y) ⇒ (x/4, y/4). The new point is (4, -1)

Point 1: (4, -1)

Point 2: (-2, 2)

Gradient = (-1 - 2)/(4 - (-2)) = -3/6 = -1/2

3.

Point 1: (4, 6)

Point 2: (-4, -6)

Gradient = (6 - (-6))/(4 - (-4)) = 12/8 = 3/2

Answer:

Step-by-step explanation:

Each term in the sequence is 4 less than the previous term.  That indicates an arithmetic sequence, which has the form a(n) = a(1) + d(n -1), where d is the common difference.  Here the common difference is -4, and so the appropriate sequence is

a(n) = 14 - 4(n - 1)

In the recorded test scores 90 is the mode, as it appears most frequently in the set of ff test scores.

Job applicants submitted their ff test results, which were as follows: 65, 68, 70, 75, 88, 90, 90, 91, and 92. Following that, the Mean (Average) is 81, Median (Middle) is 88, and Mode (Most Common) is 90. The mode can be calculated quite easily.

After sorting the numbers in a set according to their order—lowest to highest or highest to lowest—count how many times each number appears in the group.

The mode is the one that is most prevalent. the quantity that happens the most frequently, or the quantity that appears the most frequently overall. The mode of the numbers 4, 2, 4, 3, 2, and 2 is 2, since it appears three times, more than any other number. The most frequent number in a set of numbers is called the mode.

To find the mode, we first need to put the test scores in order from lowest to highest:

65, 68, 70, 75, 88, 90, 90, 91, 92

Then we can count how many times each number appears:

65: 1 time

68: 1 time

70: 1 time

75: 1 time

88: 1 time

90: 2 times

91: 1 time

92: 1 time

As we can see, the number 90 appears the most with 2 times, so the mode of this set of data is 90.

Answer:

a = $ 18

Step-by-step explanation:

It is given that Chinase's allowance is $6 per week and it is 1/3rd of his brother's allowance. Assuming the brother's allowance as "a", we can write the equation as follows:

[tex]\$6 = \frac{a}{3}\\a = (\$6)(3)[/tex]

a = $ 18

Therefore, the allowance earned by Chinse's brother every week is found to be $ 18.

Answer:

Step-by-step explanation:

a) x and 53 are adjacent angles of a parellelogram:

therefore, their sum will be 180 degrees

x + 53 = 180 --> x = 180 - 53 = 127 degrees

b) We know that opposite angles in a parallelogram are equal:

therefore, x = 113 degrees

c) Similarly, x = 80 degrees

d) x + 62 = 180

x = 180 - 62 =  118 degrees

The transformation of S(1,-4), R(2,0), 2(3,0), and P(3,-2) is S(-6, -2), R(-6, 2), as well as the category is rotation transformation.

Four distinct approaches to modify the position and/or shape of a point, line, or geometric figure are collectively referred to as transformations. The Pre-Image, which refers to the object's initial shape, and the Image, which refers to the object's ultimate shape and location after transformation, are both terms. Transformations can be divided into three categories: translations, reflections, and dilations. There are two types of transformations that can be done to a function: vertical (which affects the y-values) and horizontal (affects the x-values). The four transformation variables are included in the equation of a function that is shown below (a, b, h, and k). changing the log. Take the log of every observation as an example. Transposition by the square root. The square root of each observation is what is need for this.

Length is 14

Width is 17.5

Height is 6.4

Solve.

[tex]\sf{14*17.5*6.4=1568}[/tex]

Therefore, the correct answer is 1568.

Answer:

P: the principal, the amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.

P = $1000, t = 2 years, r = 0.08.

A = 1000(1+0.08(2)) = 1000(1.16) = 1160

Compound Interest:

P: the principal, amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

n: the number of times it is compounded.

Ex2:Suppose that $5000 is deposited in a saving account at the rate of 6% per year. Find the total amount on deposit at the end of 4 years if the interest is:

P =$5000, r = 6% , t = 4 years

a) simple : A = P(1+rt)

A = 5000(1+(0.06)(4)) = 5000(1.24) = $6200

b) compounded annually, n = 1:

A = 5000(1 + 0.06/1)(1)(4) = 5000(1.06)(4) = $6312.38

c) compounded semiannually, n =2:

A = 5000(1 + 0.06/2)(2)(4) = 5000(1.03)(8) = $6333.85

d) compounded quarterly, n = 4:

A = 5000(1 + 0.06/4)(4)(4) = 5000(1.015)(16) = $6344.93

e) compounded monthly, n =12:

A = 5000(1 + 0.06/12)(12)(4) = 5000(1.005)(48) = $6352.44

f) compounded daily, n =365:

A = 5000(1 + 0.06/365)(365)(4) = 5000(1.00016)(1460) = $6356.12

Formula to find the area: A=πr^2

Formula to find circumference: C=2πr

Diameter is twice the length of the radius, so if you're given diameter of 3, the radius is half of that, which that would be 1.5.

A=π(1.5)^2 A= 3.14x1.5^2 = 7.065

Don't forget to round that and that becomes 7.07.

C=2π(1.5) C= 2x3.14x1.5 = 9.42

That stays as it is.

Area= 7.065

Circumference= 9.42

Answer:

C.

Step-by-step explanation:

The set of ordered pairs can only be a function if the x value is not repeated .Thus,only C is a function as the x values (-1,4,1,-3) are unique while the other options have a repetition of its certain x values.
