Answer:

Step-by-step explanation:

Because this is a 45-45-90 triangle, the two smaller sides are equal to each other. After you find one of them, square it, then divide by 2.

Finding the slope using two points, (5, -1) and (-8, -4)

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =-4\\y_{1} =-1\\x_{2} =-8\\x_{1} =-5$

^^^Plug these numbers into the formula for slope...

$\frac{-4-(-1)}{-8-5}$

$\frac{-3}{-13}$

$\frac{3}{13}$

^^^This is your slope

Hope this helped!

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,722. Suppose that a

Answer:

Option C - Reject H0. We have convincing evidence that the mean salary offer for accounting graduates of this university is higher than the national average of $48,722.

Step-by-step explanation:

First of all let's define the hypothesis;

Null hypothesis;H0; μ = $48,722

Alternative hypothesis;Ha; μ > $48,722

Now, let's find the test statistic for the z-score. Formula is;

z = (x' - μ)/(σ/√n)

We are given;

x' = 48,722

μ = 49,870

σ = 3900

n = 50

Thus;

z = (49870- 48722)/(3900/√50)

z = 2.08

So from online p-value calculator as attached, using z = 2.08 and α = 0.05 ,we have p = 0.037526

This p-value of 0.037526 is less than the significance value of 0.05,thus, we reject the claim that that the mean salary offer for accounting graduates of this university is higher than the national average of $48,722
