Answer:
0.99145 is the probability that the system will work properly.
Step-by-step explanation:
We are given the following information:
The components function independently of one another.
We treat component working properly as a success.
P(component working properly) = 0.9
Then the number of components follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 5 and x = 3
For the system to function if atleast 3 out of 5 will work properly.
We have to evaluate:

0.99145 is the probability that the system will work properly.
Answer:
35 weeks
Step-by-step explanation:
12000=8500+100x
8500 from 12000 is 3500.
3500/100 is 35. 35 is x.
to check answer:
(35*100)+8500=
12000
Answer: B
Step by Step
5y + 6 = -3X
5y = -3X - 6
Y = -3/5X -6/5
Perpedicular is the flip of your slope so -3/5 becomes 5/3X
I think the answer is 5 feet because 2(2+5)= 4+10=14. So the missing length is 5 feet.
Answer:
6 + 3
or 6 - 3
Step-by-step explanation:
x^2 - 12x + 36 = 90
x^2 - 12x - 54 = 0
x = 
a = 1, b= -12, c= -54
6 + 3
or 6 - 3
