Answer:
A. The increase in the number of pounds a boy gains each year.
Step-by-step explanation:
A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is
y = 1.73x + 80.13 ............ (1)
where x represents the age of the boys and y represents the weight of the boy corresponding to his age.
Therefore, the slope of the equation (1) represents the increase in the number of pounds a boy gains each year. (Answer)
The answer is B) 43<span>°
Angle ADB is an inscribed angle which means arc AB has an angle twice that of angle ADB. The angle of the arc would be the same as that of the central angle AOB. So, mAOB = 86</span>°. And since, mAOB = mBOC, then mBOC = 86° and arc BC has a measure of 86° as well. Angle BDC intercepts the arc BC which means half of the angle of arc BC is mBDC. So, mBDC = 43<span>°.</span>
Bill's age = x
Eya's age = 3x - 5
Eya is 28
28 = 3x - 5
28 (+5) = 3x -5 (+5)
33 = 3x
33/3 = 3x/3
x = 11
Bill = x
x = 11
Bill is 11 years old
hope this helps
