A recent national survey found that high school students watched an average (mean) of 7.1 movies per month with a population sta
muminat

Answer:

H0: μc ≤ μs    Ha :μc > μs    

Step-by-step explanation:

The null and alternate hypotheses can be stated as

H0: μc ≤ μs    Ha :μc > μs    one tailed test

Where

μc =  Mean of college students watching movies in a month

μs  =  Mean of school students watching movies in a month

For one tailed test of α =0.05   the value of Z= ± 1.645

The critical region will be Z >  ± 1.645

It is of importance to note that by rejecting the null hypothesis and accepting the alternate hypothesis we are automatically rejecting all values of mean that are greater than 7.1

Penny solved an equation by subtracting 6 from each side of the equation and then dividing each side by 5.
VikaD [51]

Answer:

Step-by-step explanation:

In order to solve for x, she had to first subtract 6 on both sides of the equation.  Then divide by 5 on both sides of he equation.  After the division part, she was able to successfully isolate x.

The equation she had to solve was     (C)  5x+6=21

First step:  Subtracting 6 on both sides of equation resulted in

5x = 15

Second step:  Dividing both sides of the equation by 5 resulted in

x = 3

What is the value of x?<br> 26°<br> x =<br> = [?]
OlgaM077 [116]

Answer:

<h2><u>154°</u></h2>

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

26 - 26 = 0

180 - 26 = <u>154</u>

x = <u>154°</u>
