Answer:
The probability that at most 1 car will require major engine repair next year is P=0.3392.
Step-by-step explanation:
This can be modeled as a binomial random variable, with n=22 and p=0.1.
The probability that exavtly k cars will require major engine repair next year is:

Then, the probability that at most 1 car will require major engine repair next year is:

Answer:
a) 40 hours
b) 60 hours
C) 100 hours
Step-by-step explanation:
0.2a + 0.3b+0.5c = 76
Hence: 0.2* (0.2 λ) +0.3*(0.3 λ )+0.5*(0.5 λ ) = 76
0.38 λ =76
λ = 76/0.38 =200
Thus : 40, 60, 100
Answer:
y< -3/2x-2
Step-by-step explanation:
if you look at the graph, you can see the line is dotted, which means it is not equal to. eliminate a and c. the shade is toward the bottom of the y, which then you could eliminate a because b says the y value is greater than, which isn't true. you could also check it by plugging in any value for x!
hope this helped :)
