I’m pretty sure the answer would be 4
Answer:
pounds
Step-by-step explanation:
Let x pounds of $ 0.66 per lb candies mixed with y pounds of $ 1.31 per lb candies to obtain 9 lb of $ 0.97 per lb candies,
Hence, we can write,
x + y = 9 ------- (1)
And, 0.66 of x + 1.31 of y = 0.97 of (x + y)
⇒ 66 x + 131 y = 97 (x+y)
⇒ 66 x +131 y - 97 x - 97 y = 0
⇒ -31 x + 34 y = 0 ------(2)
By solving equation (1) and (2)
We get,
and 
Hence, the quantity of 0.66 per lb candies =
pounds
Answer:

Step-by-step explanation:
Given


Required
Determine MSE
This is calculated as:

Where:

denominator df
So, we have:


To calculate the df, we have:
--- observations
treatments
So:




So, we have:



A≈21.46
First you find the area of the square
A=a^2 which is
=10^2
A=100
Then you find the area of the circle
A=πr^2
= π(5)^2
A≈78.54
Now you subtract the 78.54 from 100 to get 21.46
