Answer:
The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Step-by-step explanation:
The least square regression line is used to predict the value of the dependent variable from an independent variable.
The general form of a least square regression line is:

Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>α</em> = intercept
<em>β</em> = slope
The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:

Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:


Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Answer: 7 days
Step-by-step explanation:
From the question, we are informed that a road construction company can repair 1/4 mile of road each day. We are further told that Road X is 7 ½ miles long. The number of days that it'll take to repair road X will be:
= 7 1/2 ÷ 1/4
= 15/2 × 4/1
= 30 days
Road Y is 5 ¾ miles long. The number of days that it'll take to repair road Y will be:
= 5 3/4 ÷ 1/4
= 23/4 × 4/1
= 23 days
The difference in the number of days that Road X take to repair than Road Y will be:
= 30 days - 23 days
= 7 days
