Answer: Landers

Mean = 136

Median = 133

Skakalski

Mean = 130

Median = 133

Step-by-step explanation: to find the mean add all the numbers then divide it by how many numbers there are.

To find the median write all the numbers from smallest to largest then cancel the number at the end until you reach the “middle” number.

A poll showed the approval rating to be 0.45 (45 %). A second poll based on 2500 randomly selected voters showed that 1185 app

DerKrebs [107]

Answer:

Step-by-step explanation:

Given that a poll showed the approval rating to be 0.45 (45 %)

Second poll n =2500: sample p = 1185/2500 = 0.474

H0: p = 0.45

Ha: p not equals 0.45

(Two tailed test)

p difference = 0.024

z-statistic 0.179

Significance level P = 0.8577

95% CI of observed proportion 0.24% to 0.83%

Since p>0.05 we accept null hypothesis

The results of the second poll do not indicate that the proportion of voters who approve of the job the president is doing is significantly higher than the original level

there is a stack of old algebra books in the library. Each book is 1 1/4 inches thick. let b represent the number of books in a

ELEN [110]

The equation which represents the height of the books is $s(b)=\frac{5}{4} b$

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. An equation between two sums of monomials of degree 0 or 1 is known as a linear equation.

The books are stacked one above the other and each book is $1\frac{1}{4}$ inches thick.

So to calculate the total height of the stack we have to multiply the number of books in the stack with the thickness of each book.

The total thickness is represented in the from of a function as

s(b) and the thickness of each book is $1\frac{1}{4}=\frac{5}{4}$ inches

total height= $\frac{5}{4}\times b$

Therefore the required equation is $s(b)=\frac{5}{4} b$ .
