Answer:
The answer is 17
Step-by-step explanation:
8^2+15^2=c^2
64+225=c^2
289=c^2
Square root both sides
c=17
The slope is 4.
To find the perpendicular slope, you use the negative reciprocal of the slope you already have. Since the original slope is -1/4, you flip -1/4 to get -4. You then find the negative of -4 to get 4
Answer:
The statistic for this case would be:
![z=\frac{\hat p -p_o}{\sqrt{\frac{\hat p(1-\hat p)}{n}}}](https://tex.z-dn.net/?f=%20z%3D%5Cfrac%7B%5Chat%20p%20-p_o%7D%7B%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%29%7D%7Bn%7D%7D%7D)
And replacing we got:
![z= \frac{0.436-0.4}{\sqrt{\frac{0.436*(1-0.436)}{700}}}= 1.92](https://tex.z-dn.net/?f=%20z%3D%20%5Cfrac%7B0.436-0.4%7D%7B%5Csqrt%7B%5Cfrac%7B0.436%2A%281-0.436%29%7D%7B700%7D%7D%7D%3D%201.92)
Step-by-step explanation:
For this case we have the following info:
represent the sample size
represent the number of employees that earn more than 50000
![\hat p=\frac{305}{700}= 0.436](https://tex.z-dn.net/?f=%5Chat%20p%3D%5Cfrac%7B305%7D%7B700%7D%3D%200.436)
We want to test the following hypothesis:
Nul hyp. ![p \leq 0.4](https://tex.z-dn.net/?f=%20p%20%5Cleq%200.4)
Alternative hyp : ![p>0.4](https://tex.z-dn.net/?f=%20p%3E0.4)
The statistic for this case would be:
![z=\frac{\hat p -p_o}{\sqrt{\frac{\hat p(1-\hat p)}{n}}}](https://tex.z-dn.net/?f=%20z%3D%5Cfrac%7B%5Chat%20p%20-p_o%7D%7B%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%29%7D%7Bn%7D%7D%7D)
And replacing we got:
![z= \frac{0.436-0.4}{\sqrt{\frac{0.436*(1-0.436)}{700}}}= 1.92](https://tex.z-dn.net/?f=%20z%3D%20%5Cfrac%7B0.436-0.4%7D%7B%5Csqrt%7B%5Cfrac%7B0.436%2A%281-0.436%29%7D%7B700%7D%7D%7D%3D%201.92)
And the p value would be given by:
![p_v = P(z>1.922)= 0.0274](https://tex.z-dn.net/?f=%20p_v%20%3D%20P%28z%3E1.922%29%3D%200.0274)
Answer:
3 inch
Step-by-step explanation:
1 inch = 3 feet
