Answer:

Step-by-step explanation:

3 (x – 4) = 2x + 6 Remove the brackets

3x - 12 = 2x + 6 Add 12 to both sides.

3x - 12 + 12 = 2x + 6 + 12 Combine

3x = 2x + 18 Subtract 2x from both sides

3x-2x = 2x-2x + 18 Combine

x = 18

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:

$H_1: \mu \neq 0$

If the average of x, y, and z is 32 and the average of y and z is 27, what is the average of x and 2x?

Orlov [11]

X + y + z = 32 * 3
27 + 27 + x = 96
X = 54
2x = 108
Average of x and 2x = (54+108) / 2 = 164 / 2 = 82
Average of X and 2X = 82
