Answer:
$23 an hour.
Step-by-step explanation:
divide 172.50 by 7.5
85km/ h
a) 60
b) 0.24
c) 150
a) P(green) = ⅕
Expected no. = 300 × ⅕
= 60
b) total = 300
P(purple) = 72/300
= 6/25 = 0.24
c) P(blue) = 45/300
= 3/20 = 0.15
Expected no.: 1000 × 0.15
= 150
f(- 6) = 70
To evaluate f(- 6) , substitute x = - 6 into f(x)
f(- 6) = 2(- 6)² - 2 = 2(36) - 2 = 72 - 2 = 70
Answer: (7+1/7) *(7+7)
