The coordinates of B are (12,9). x=3+ (3-(-6))=12 y=5+ (5-1) = 9

The slope of the line that goes through points A(8, 7) and B(5,-2) is 3. m = (y2-y1)/(x2-x1); m = (-2-7)/(5-8); m = -9/-3; m = 3

A refrigerator conatins 12 orange drinks, 4 grape drinks, and 25 apple drinks. Ann is first in line for drinks. Mark is second. What is the probability that Ann gets an apple drink and Mark gets a grape drink if they are given drinks at random?
Weegy: ann is 60 percent probabe will get apple drink, mark is 9.6 probable will get grape drink (More)

The probability that Ann gets an Apple drink is 25/41 ~ 0.60975609 ~ 61.0% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The probability that Mark gets a grape drink is 4/40 = .1 = 10%
Gino has 5 blue socks and 4 black socks. He selects one sock at random. Without replacing the sock, he selects a second sock at random. Find this probability: P(blue, then black)
Weegy: well you would have 80% to get a blue sock and 60 % to get a black one (More)

Gino has 5 blue socks and 4 black socks. He selects one sock at random. Without replacing the sock, he selects a second sock at random. Probability: P(blue, then black) = 5/9 * 4/8 = 5/9 * 1/2 = 5/18
