Answer:

steps

1) 14/28 to convert to a percent you have to first divide the numerator from the demoninator and then  you  multiply by 100 and you get get %50 (you could had known bc 14 is half of 28)

2) 5/28 do the same thing as the first step and get %17.85

Answer:if you double all of the dimensions of a rectangular prism, you create a similar prism with a scale factor of 2. The surface area of the similar prism will increase as the square of the scale factor (22 = 4) and the volume will increase as the cube of the scale factor (23 = 8).

Step-by-step explanation:

Scale factor are used to increase or diminish the original figrure. The new volume will be 8times larger than the initial volum

Scale factor are used to increase or diminish the original figrure.

Assume the original dimension of the figure is a, b and c, the volume of te figure will be expresed as:

A = length * width * heiht

A = abc

If the measure of the sides are doubled, hence;

New volume = 2a * 2b * 2c

New volume = 8abc

Ratio = 8abc/abc
Ratio = 8

Hence the new volume will be 8times larger than the initial volume

Answer:

g(3)=9

Step-by-step explanation:

We want to find what g(x), or y is, when x is equal to 3.

Therefore, we can substitute 3 in for x in the equation

g(x)=x^2

g(3)=3^2

Evaluate the exponent

g(3)=3*3

g(3)=9

C. Fair Credit Billing Act

Step-by-step explanation:PLATO

Answer:

The difference between the number of expected outcomes and the number of actual outcomes = 5

Step-by-step explanation:

She tosses a two sided counter and spins a spinner with six equal sized sections numbered 1 to 6.

Probability of the counter landing on either of the two sides is exactly = (1/2)

Probability of the counter landing on the red side = (1/2)

Probability of the spinner landing in a region greater than 3 = Probability of the spinner landing in a region of 4, 5 or 6. = (3/6) = (1/2)

In one toss and spin, the probability of a toss landing on red and the spinner landing on a number greater than 3 = p = (1/2)×(1/2)

p = (1/4)

Expected number of times that a toss will land on a red and a spinner will land on a number greater than 3 in 80 trials

= np = 80 × (1/4) = 20

Number of actual times that the toss lands on a red and a spinner lands on a number greater than 3 in 80 trials = 25

The difference between the number of expected outcomes and the number of actual outcomes = 25 - 20 = 5

Answer:

26

Step-by-step explanation:

I subtracted DF and DE to find the missing difference for the segment EF. I'm not sure if this is correct though. I hope it helps.

The length of line segment EF is 26.

A line segment is a subset of a line which has two endpoints.

A ray has one end point and extends indefinitely on the other direction.

A line extends indefinitely on both of it's directions.

From the given data

Line segment DF has a length 38 and line segment DE has a length 12.

To find the length of line segment EF we have to subtract the length of line segment DE from length segment DF.

∴ EF = DF - DE

  EF = 38 - 12'

  EF = 26.

So, the line segment EF has a length of 26.

C. [tex]c = \frac{-7+-\sqrt{129} }{8}[/tex]

Step-by-step explanation:

Before we start, you can think of the variable "c," as x.

The quadratic formula/equation is:

[tex]x = \frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]

The setup is:

[tex]ax^2+bx+c=0[/tex]

[tex]4c^2+7c-5=0[/tex]

Plug in the numbers accordingly to the letter associated, like so:

[tex]x = \frac{-7+-\sqrt{7^2-4(4)(-5)} }{2(4)}[/tex]

[tex]x = \frac{-7+-\sqrt{49+80} }{8}[/tex]

[tex]x = \frac{-7+-\sqrt{129} }{8}[/tex]

Answer:

6 Over 10

Step-by-step explanation:

I did the math and got 100% on my Unit Test.

Interest formula: A = Pe^rt

A = amount

P = principal amount

r = interest rate

t = time

We know that in the question we have:

P = 8,000

r = 0.019

t = 6

Now, solve with the given values:

A = 8000e^(0.019*6)

A = 8000e^(0.114)

A = 8966.016...

Round to the nearest hundredth:

8966.016... → 8,966.02

Therefore, the answer is [ $8,966.02 ]

Best of Luck!

Answer:

$8,966.02

Step-by-step explanation:

Amount = 8000 × e^(6 × 1.9/100)

Amount = 8000 × e^0.114

Step-by-step explanation:

Answer:

The sample proportion is 0.253.

Step-by-step explanation:

We are given that a 90% confidence interval for a proportion is found to be (0.22, 0.28).

Firstly, as we know that the confidence interval for sample proportion is calculated as;

90% confidence interval = Sample proportion [tex]\pm[/tex] Margin of Error

Here, let [tex]\hat p[/tex] = sample proportion

Also, the level of significance = 1 - 0.90 = 0.10 or 10%

And, the critical value of z at 5% (two-sided) level of significance is 1.645.

So, 90% confidence interval =  [tex]\hat p \pm 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]

           (0.22 , 0.28)    =   [tex]\hat p \pm 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]

This means;  

          0.22  =  [tex]\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]  -------------- [Equation 1]

          0.28  =  [tex]\hat p + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]  -------------- [Equation 2]

From equation 1 and 2, we get;

           [tex]0.22 + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }= 0.28 - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]

           [tex]1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} } + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }= 0.28 -0.22[/tex]

             [tex]2 \times 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} } =0.06[/tex]

                 [tex]\sqrt{\frac{\hat p(1-\hat p)}{n} } =\frac{0.06}{2 \times 1.645}[/tex]

                  [tex]\sqrt{\frac{\hat p(1-\hat p)}{n} } =0.02[/tex]

Now, squaring both sides, we get;

                    [tex]{\frac{\hat p(1-\hat p)}{n} } =0.0004[/tex]

                      [tex]n ={\frac{\hat p(1-\hat p)}{0.0004} }[/tex]

Now, putting value of n in equation 1, we get;

                    0.22  =  [tex]\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]  

                    0.22  =  [tex]\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{\hat p(1-\hat p)}\times 0.0004 }[/tex]

                    0.22  =  [tex]\hat p - 1.645 \times \sqrt{ 0.0004 }[/tex]

                    0.22  =  [tex]\hat p -( 1.645 \times 0.02)[/tex]

                    0.22  =  [tex]\hat p -0.033[/tex]

                      [tex]\hat p = 0.22 + 0.033[/tex] = 0.253

Therefore, the sample proportion  [tex]\hat p[/tex] is 0.253.

Answer:

x = -6

Step-by-step explanation:

0 = In(x + 7)

x + 7 = e⁰

x + 7 = 1

x = 1 - 7

x = -6

Steps to solve:

0 = In(x + 7)

~Log definition

e^0 = x + 7

~Simplify

1 = x + 7

~Solve for x

1 - 7 = x + 7 - 7

-6 = x

Therefore, the answer is x = -6
