Papessa [141]

The slope means : A.

the increase in the number of pounds a boy gains each year

Explanation:

Given the equation for line of best fit as : y=1.73x +80.13

At the age of 5 the weight will be;

x=5, y= 1.73*5+80.13 =88.75 pounds

At the age of 6, the weight will be;

x=6, y=1.73*6+80.13 = 90.15

Difference in weight after one year increase of age will be;

90.15-88.75=1.73

This means after a year, a boy gains 1.73 pounds

Choose the most correct scenario for a sunny summer afternoon at a parking lot.

vitfil [10]

Answer:

D. Solar radiation heats the asphalt; the air immediately above is heated through conduction; the warm air rises in free convection.

Explanation:

As the parking lot is exposed to the sun, on a sunny afternoon, we can consider that the sun is radiating with high intensity in this environment, causing the asphalt to be strongly heated. In this case, the air that comes in contact with the asphalt ends up being heated, because the heat of the asphalt is transmitted by the air through the process called conduction, which is the heat transmitted by the agitation of the molecules.

The heated air becomes less dense, that is, it becomes lighter and this causes it to rise, while the cold air is more dense and descends, coming into contact with hot asphalt and also heating up. In that case, a heat transfer called convection occurred.
