Answer: find the answers in the explanation.
Step-by-step explanation:
Given that the predicted Number of Text Messages Sent = 60 – 0.8 • Age
Where the slope = - 0.8
The intercept = 60
1) the slope of the least regression line is -0.8
2.) The unit of the slope of the line is text per year
3.) Therefore, the slope of the line tells you that for every year older the smart phone user is, you can expect a typical average in text messages sent of - 0.8
4.) The y - intercept of the least square regression line is 60
5.) The unit of the y - intercept of the line are text sent
6.) The y - intercept of the line tells you the starting point. The first number of text messages sent.

The expression representing the total price of the truck including the sales tax is 1.07p
Step-by-step explanation:
The total price of the Truck can be calculated by adding the cost of the Truck to the sales tax of the Truck
From the question, the cost of the truck is $ p while the tax is 0.07p
So the total price of the truck will be;
p + 0.07p
= p( 1 + 0.07)
= p(1.07)
= 1.07p
