3) A construction company uses 900 bricks to
denis-greek [22]

Answer:$570

Step-by-step explanation:If it is 900 for 2 walls, and they need 6 walls, then multiply 900 by 3. They would use 2700 bricks for 6 walls. Multiply 2700 by 0.10 to get the price for all the bricks, 270 dollars. If labor to build each wall costs 50 dollars then multiply that by 6 and add it to the 270 dollars. It costs 570 dollars to build 6 walls

e-lub [12.9K]

Answer:

c. results in either of two directions can lead to rejection of the null hypothesis.

Step-by-step explanation:

A two tailed test is performed when we want to test if there is statistically significant difference from the null state. That means that if the statistic value is significantly higher or significantly lower, we will reject the null hypothesis. Both tails have rejection areas.

Write the equation of the line in fully simplified slope-intercept form
DochEvi [55]

Answer:

y = 3x - 7

Step-by-step explanation:

Slope - Intercept Form :  y = mx+b

m = slope

b = y - intercept

Slope =  \frac{rise}{run}

          = \frac3{1}

          = 3

So far:   y = 3x + b

Plug in a point from the graph, ex. (3,2)

2 = 3(3) + b\\\\2 = 9 + b\\\\b = -7

Equation :   y = 3x - 7

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
