B ) 75 Miles per hour
75 + 64(10) = 640 + 75 = 715
715 ÷ 11 ( how many drivers ) = 65

B) Determine y when x = 10 and solve the equation y = 18 (where you print y with the right side in your specification)</span>
7x = -x + 24
+x. +x
8x = 24
X = 3
Step-by-step explanation:
p = 0.1, q = 0.9, n = 7
a) Use complementary probability.
P(at least 1) = 1 − P(0)
P(at least 1) = 1 − (0.9)⁷
P(at least 1) = 0.522
b) Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
P(3) = ₇C₃ (0.1)³ (0.9)⁴
P(3) = 0.023
Formula:
y = 60x
1 hour = 60 minutes
