Answer:
p=0.063
Step-by-step explanation:
Let X be number of the certain brand of jelly beans that are made so that each package contains about the same number of beans.
X is N(375, 8)
YOu are collecting a sample size of
n = 8
Findings from the sample


(Left tailed test at 5% level)
Since sample size is small though sigma is known we use Z test, since norm
Mean difference = -5
Std error = 
Test statistic t = mean diference / std error = 
df = n-1 =5
p value = 0.063
Answer:
They are equal.
Step-by-step explanation:
First, we can simplify the second equation by multiplying 7 times 6 and then 7 times 5 due to the distributive property.

Therefore, using the distributive property, they are equal.
Answer:
The average rate of change = -10
The crop yield decreased by 10 pounds per acre from year 10 to year 20.
Step-by-step explanation:
A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function
models the crops in pounds per acre over x years.
The average rate of change can be calculated using formula

In your case,

then

and the average rate of change is

This means the crop yield decreased by 10 pounds per acre (negative rate of change) from year 10 to year 20.
Since we know that a negative times a negative equals a positive, we know that our answer is positive. Then follow the steps below.
