A scientist who studies sleep has developed a new technique to help people sleep each night. He
Andru [333]

Considering the situation described, the scientist's null and alternative hypothesis are described by:

Null hypothesis H_0: \mu = 0; Alternative hypothesis H_1: \mu \neq 0.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by \mu is of 0, hence:

H_0: \mu = 0

At the alternative hypothesis, it is tested if there is a difference, hence:

H_1: \mu \neq 0

What is an estimate for the square root of 150? (Do not find the exact value) Show work
Umnica [9.8K]

Answer:

Somewhere between 12 and 13, perhaps 12.25

Step-by-step explanation:

This is a (rather) simple explanation:

Look for 2 square numbers that are either side of 150

In this case, it is 144 and 169

The square root of 144 is 12 and the square root of 169 is 13

Therefore we can estimate that the square root of 150 is somewhere between 12 and 13.

As 150 is a lot closer to 144 to 169, I would estimate around 12.25 but you do not need an exact value :)

What is the equation for the line that has a slope of 0 and passes through the point (3, 7)?
Harrizon [31]

Answer:

Step-by-step explanation:

PART 1

y=mx+b

m is slope and slope is 0 sooo

y=0x+b

it passes through (3,7)

7=0(3)+b

7=0+b

b=7

y=0x+7

so just y=7

PART 2

y=mx+b

y=1/5x+b

1/2=1/5(-2/3)+b

1/2=-2/15+b

1/2+2/15=b

15/30+4/30=b

19/30=b

y=1/5x+19/30
