A research hypothesis proposes that consuming low carbohydrate diets results in increased weight loss. One group of participants follows a low-carb diet for 4 weeks, whereas a second group follows a high-carb diet containing the same number of calories for 4 weeks. The average number of pounds lost for each group is then is compared. What is the dependent variable?

The dependent variable is pounds lost for each group.

Step-by-step explanation:

We are given the following in the question:

A hypothesis is done to measure the average number of pounds lost based on the fact whether a person follows a low carb diet or high carb diet.

Dependent and independent variable:

For the hypothesis:

Independent variable:

Participants of a group follows a low-carb or high carb diet for 4 weeks.

Dependent Variable:

average number of pounds lost for each group

Thus, the dependent variable is pounds lost for each group.

f(x) = y

f(-3) = -5

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
