Probability that the 7th grader is a boy = number of boys / total kids = 5 / (5+5) = 5/10 or 1/2Probability that the 8th grader is a boy = number of boys / total kids = 3 / (5+3) = 3/8Probability that both are boys is calculated by multiplying both of the answers above: ½ * 3/8 = 3/16 or 0.1875
Hi
85% ⇒ 68
100% ⇒ x
85x = 100·(68)
85x = 6800
x = 6800/85
x = 80
Answer: 80
A perpendicular line has a slope of infinity. Therefore it is not possible to write the equation in point-slope form.
