Step-by-step explanation:
f(x) = x² - 4
g(x) = 7 - x
= (fog)(2)
= x² - 4
= (7 - x)² - 4
= (7 - 2)² - 4
= 5² - 4
= 25 - 4
= 21
(fog)(2) = 21
Answer:
The probability of getting 2 defective items
P(X=2) = 0.0317416
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that size of the components n = 10
Given that the probability of getting the defective item
p = 3% = 0.03
q = 1-p =1- 0.03 = 0.97
Let 'X' be a random variable in a binomial distribution

<u><em>Step(ii):-</em></u>
The probability of getting 2 defective items


P(X =2) = 45 × 0.000705
P(X=2) = 0.0317416
Answer:
46.6028 Miles
Step-by-step explanation:
If you're looking for the amount of miles they'd traveled, this is the exact amount. If you're looking for your answer in Kilometers, they'd travel 70 km total.
35 km/hr x 2 = 75 km total
Hope this helped! If it didn't let me know what you need help solving.
