Answer:
Total stocked of crayfish is = 315.2
Step-by-step explanation:
Given data:
stocked of crayfish 
in 1000 gallon water tank
size of tank = 3 ft deep and 6 feet diameter
let radius of tank is r and height of tank is h m
Total stocked of crayfish is
![= 20[ 2\pi r(r+h) ft^2]](https://tex.z-dn.net/?f=%20%20%3D%2020%5B%202%5Cpi%20r%28r%2Bh%29%20ft%5E2%5D)
[1 ft = 0.3048 m]
= 315.2
Answer:
Step-by-step explanation:
Type I error occurs when the null hypothesis is rejected even when it is true.
Type II error occurs when the null hypothesis is not rejected even when it is false.
The null hypothesis is
The mean annual consumption = the national mean
The alternative hypothesis is
The mean annual consumption < the national mean
1) it is a type II error because the null hypothesis was not rejected even when it is false
2) it is a correct decision because the decision corresponds to the outcome
3) it is also a type II error
d) it is a correct decision because the null hypothesis is accepted when it is true
A: 100m^2
10 x 10 = 100
B: 28.274m^2
You have to do pi x r squared
So,,,
Pi x 3^2
9pi = 28.274....
C: just subtract the grass bed from the land...
100 - 28.274 = 71.72566612...
So C is 71.726m^2
Hope this helped! Have a nice day :)
