Suppose that participants who adhere to a particular weight loss program lose an average of 1.5 lbs per week. Write a population
luda_lava [24]

Answer:

y = x₂ - 1.5 × x₁.

Step-by-step explanation:

Regression model is a technique of analysis in which a variable known as dependent variables and another variables known as the independent variables are analyzed to determine their relationship.

So, from the question given above we have that; "Suppose that participants who adhere to a particular weight loss program lose an average of 1.5 lbs per week".

Also, we are given that time = x1 (in weeks) and weight = x2 (in pounds). Therefore the regression equation is given as below;

y = x₂ - 1.5 × x₁.

Sharon is the youngest in her family. Her sister Anne is 3 years older than she is. Her brother Tom is 5 years older than Anne.
eduard
We represent Sharon's age by S; let Anne's age be A and Tom's age be T. In this case, the second statement is represented by A = 3 + S. The third statement is T = 5 + A. The fourth statement is represented by T + S + A = 62Solving the four equations: T = 25, S = 17, and A = 20. Hence Sharon's age is 17.
