A certain brand of jelly beans are made so that each package contains about the same number of beans. The filling procedure is n
pantera1 [17]

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

\bar x =370\\

H_0: \bar x =375\\H_a: \bar x

(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 = \frac{8}{\sqrt{8} } =2.828

Test statistic t = mean diference / std error = \frac{-5}{2.828} \\=-1.768

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.

42+35 = 7(6+5)?\\42+35=(7 * 6)(7 * 5)\\42+35=42+35\\

Therefore, using the distributive property, they are equal.

A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 100 mo
Aliun [14]

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 f(x) =-x^2 + 20x + 100 models the crops in pounds per acre over x years.

The average rate of change can be calculated using formula

\dfrac{f(b)-f(a)}{b-a}

In your case,

a=10\\ \\b=20,

then

f(a)=-10^2+20\cdot 10+100=-100+200+100=200\\ \\f(b)=-20^2+20\cdot 20+100=-400+400+100=100

and the average rate of change is

\dfrac{100-200}{20-10}=\dfrac{-100}{10}=-10

This means the crop yield decreased by 10 pounds per acre (negative rate of change) from year 10 to year 20.
