A class has two sections. Section I had 56 students of whom 10 received A grades. Section II had 44 students of whom 11 received A grades. Now 1 of the 100 students is chosen at random. a) What is the probability that the student received an A grade?
b) What is the probability that the student was in Section I if the student is known to have received an A grade?

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

point m is on plane r
