Answer:
what
Step-by-step explanation:
Part B: In complete sentences, describe the show pony's weight gain in terms of the units used in the data.
Part C: According to the equation for the best fit line for the data, approximately how much weight would you expect the pony to gain in a week if its additional daily caloric intake for that week is 2,300 calories?
Answer:
$22
Step-by-step explanation:
First, you should add the two values, $130 and $24. When you do, you get $154. Then, divide $154 by 7, to see how much he needs to earn each week. Your answer should be $22.
Answer:
175 square feet
Step-by-step explanation:
the area of the whole thing is 400 ft. (20 x 20=400)
i got the 20 from the perimeter b/c 20+20+20+20=80
then subtract the area of the pool from 400 to get 175.
Answer:
Z = -6.3
Step-by-step explanation:
Given that:
![\mathbf{H_o :p= 0.28}](https://tex.z-dn.net/?f=%5Cmathbf%7BH_o%20%3Ap%3D%200.28%7D)
![\mathbf{H_o :p < 0.28}](https://tex.z-dn.net/?f=%5Cmathbf%7BH_o%20%3Ap%20%3C%200.28%7D)
Since the alternative hypothesis is less than 0.28, then this is a left-tailed hypothesis.
Sample sixe n = 800
= 0.217
The standard error ![S.E(p) = \sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=S.E%28p%29%20%3D%20%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
![S.E(p) = \sqrt{\dfrac{0.28(1-0.28)}{800}}](https://tex.z-dn.net/?f=S.E%28p%29%20%3D%20%5Csqrt%7B%5Cdfrac%7B0.28%281-0.28%29%7D%7B800%7D%7D)
![S.E(p) \simeq0.015](https://tex.z-dn.net/?f=S.E%28p%29%20%5Csimeq0.015)
Since this is a single proportional test, the test statistics can be computed as:
![Z = \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7B%5Chat%20p%20-%20p%7D%7B%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D)
![Z = \dfrac{0.217- 0.28}{0.01}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7B0.217-%200.28%7D%7B0.01%7D)
Z = -6.3
Answer:
$0.1
Step-by-step explanation:
From the information given, you know that Mikayla and Weatha spent the same amount of money and because of that you can write the following:
6.25+75x=4.75+90x, where x is the price of a small piece of candy
Now, you can solve for x:
6.25-4.75=90x-75x
1.5=15x
x=1.5/15
x=0.1
According to this, the answer is that a small piece of candy costs $0.1.
