A linear regression equation was created to use the weight of a newborn baby seal to predict it's lifespan (LaTeX: YY). The equation of the regression line is LaTeX: \text{lifespan} = 3 + 1.3 \times \text{birth weight}lifespan = 3 + 1.3 × birth weight. Which is the response variable, and why?

Title:

Step-by-step explanation:

Response variable means the variable which we are trying to measure and explain.

According to the given question, Life span = 3 + 1.3(birth weight).

Here, we are trying to find the life span of a newborn baby.

Hence, in this question, according to the given scenario life span is the response variable.

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
