Answer:

The correct answer is False.

Step-by-step explanation:

To help explain or predict the response variable in every regression study, we use one or more explanatory variables. These variables are also called response variables or dependent variables.

The risk factors and confounders involved are called predictor or independent variables.

These definitions are a part of regression analysis which is a technique to asses the relationship between one or more risk factors and a particular outcome variable.

PLEASE HELP ME!?!?!?!?!​

Part 1:

A. Like terms must have the same variable and exponent.

B. Give an example of two terms that cannot be combined: 7c and 4b

C. Write one complete sentence to explain why the two terms you wrote cannot be combined: 7c and 4b cannot be combined because they have different variables, and are therefore not like terms.

D. Use distributive property: 2(-4 + 6.1) + 3(5 - x)

2 * -4 = -8

2 * 6.1 = 12.2

-8 + 12.2 + 3(5 - x)

3 * 5 = 15

3 * x = 3x

-8 + 12.2 + 15 -3x

-8 + 12.2 = 4.2

4.2 + 15 = 19.2

19.2 - 3x is the simplest version.

Part 2:

A. Thor is wrong because, in step 4, he subtracted to isolate the variable when he should have divided.

B. 4x + 9 = 6

Step 1: 4x + 9 - 9 = 6 - 9

Step 2: 4x = -3

Step 3: 4x/4 = -3/4

Step 4: x = -0.75

Gre4nikov [31]

Answer:

38.4

38.4 is 48% of 80

Step-by-step explanation:

What is 48% of 80?

Y is 48% of 80

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 48% * 80

Converting percent to decimal:

p = 48%/100 = 0.48

Y = 0.48 * 80

Y = 38.4
