Answer:

  452.4 ft

Step-by-step explanation:

The circumference of a circle is given by the formula ...

  C = 2πr . . . where r is the radius

Filling in the given number, we find the circumference to be ...

  C = 2π(72 ft) = 144π ft ≈ 452.4 ft

The distance around the outside edge is about 452.4 feet.

Answer:

YX < YW < XW

Step-by-step explanation:

12v +(v+57) + (v+39) = 180

14v + 96 = 180

14v = 84

v = 6

3 angles from smallest to largest: 72° (12v) (XW) , 63° (v+57)(YW) , 45° (YX)

side length: YX < YW < XW

Step 1 of 3: Each year a nationally recognized publication conducts its Survey of America’s Best Graduate and Professional Schoo
lukranit [14]

Answer:

Step-by-step explanation:

Hello!

Given the variables

Y: Starting salary of a graduate at a top business school

X: GMAT score of the business school

The sample used had a size n=20

The estimated regression equation was ^Y= -92040 + 228Xi

The correlation coefficients were r= 0.81

You need to know if r is statistically significant at a 0.05 level:

Assuming the hypotheses are:

H₀: There is a linear correlation between the variables of interest

H₁: There is no linear correlation between the variables of interest

α: 0.05

This test is two-tailed.

The p-value for a r=0.81 and n=20 is 0.000015

Using the p-value approach, the decision rule is:

If p-value ≤ α, reject the null hypothesis

If p-value > α, do not reject the null hypothesis

In this case, the p-value is less than α, the decision is to reject the null hypothesis.

At a 5% level, you can conclude that the coefficient of correlation is statistically significant.

Veronica works each day and earns more money per hour the longer she works. Write a function to represent a starting pay of $20
MArishka [77]

<u>Answer:</u>

The range of the amount Veronica makes each hour if she can only work a total of 8 hours is 20 ≤ x ≤ 29.55

<u>Solution: </u>

Let us assume that Veronica worked x hours

The starting pay is \$20

Each hour increase is 5\%

So the function is f(x)=20(1.05)^{x}

Now if she works 8 hours, she will earn, = 20(1.05)^8

\Rightarrow 20\times1.477 = 29.55

So, the range will be 20 ≤ x ≤ 29.55
