Using the given formula T = LS
And given the time is 3 minutes (3 x 60 = 180 seconds)and the speed is 4-1/2 inches per second:
180 = L x 4-1/2
Solve for L by dividing both sides by 4-1/2:
L = 180 / 4-1/2
L = 40
The length should be 40 inches.
Well I’m just trying to get points for this thing but idk
The minimum sample size required for a test with a confidence interval of
![100(1 - \alpha )%](https://tex.z-dn.net/?f=100%281%20-%20%5Calpha%20%29%25)
with a z-score of
![z_{ \alpha /2}](https://tex.z-dn.net/?f=z_%7B%20%5Calpha%20%2F2%7D)
and margin of error of E and a population proportion of p is given by:
![n= \frac{p(1-p)z_{ \alpha /2}^2 \alpha }{E^2}](https://tex.z-dn.net/?f=n%3D%20%5Cfrac%7Bp%281-p%29z_%7B%20%5Calpha%20%2F2%7D%5E2%20%5Calpha%20%7D%7BE%5E2%7D%20)
Given p = 34% = 0.34, E = 0.027,
![z_{ \alpha /2}=1.645](https://tex.z-dn.net/?f=z_%7B%20%5Calpha%20%2F2%7D%3D1.645)
Therefore,
Answer:
96sq ft. u just multiple the length by the height then square it
It would most likely be the bottom left answer
