In a high school graduating class of 138 students, 56 are on the honor roll. Of these, 52 are going on to college. Of the 82 students not on the honor roll, 61 are going on to college. A student is selected at random from the class. (a) What is the probability that the student selected is going to college?

Incorrect: Your answer is incorrect.

(b) What is the probability that the student selected is not going to college?

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
