Answer:

x = 42

Step-by-step explanation:

Collect like terms (all x together and constants together)

4x + 12 = 180

4x = 180 - 12

4x = 168

x = 168 / 4

x = 42

Answer:

x = 42

Step-by-step explanation:

First add the values with variable x and put them to one side of the equation and then do the same thing for the values without x

; x + 3x = 180 - 7 - 5

; 4x = 168....then divide both sides by 4

; x = 42

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:

$H_1: \mu \neq 0$

1.Find the dot product of the two given vectors, u=(1,6) and v=(-5,-2) 2. Find the dot product of v=-7i+4j and w=-6i+5j

Svet_ta [14]

The dot product of the two vectors will be given as follows:
v*w=(-7i+4j)*(-6i+5j)
=(-7*(-6))i+(4*5)j
=-42i+20j

Hence the answer is:
v*w=(-42i+20j)
