Answer:
1. 0.99993108.
2. 6 components.
Step-by-step explanation:
(a) Probability of 1 component failing = 0.041
So the probability of the whole system failing = 0.041^3.
Therefore the probability of not failing
= 1 - 0.041^3 = 0.99993108.
(b).
Try 5 components:
1 - 0.041^5 = 0.99999988
6:
1 - 0.041^6 = 0.9999999952.
So the answer is 6 components.
Answer:
sum of the polynomials is 
Step-by-step explanation:
Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)
adding x^3 terms, now we get


Therefore the sum of given polynomial is

Answer:
B. 33
Step-by-step explanation:
Let the number of Fuji trees be F, the number of gala be G and the total number of trees be x.
10% cross pollinated, this means 1/10 cross pollinated or 0.1x
Number of Fuji plus cross pollinated is 187.
And cross pollinated is 3/4 of total or let’s say 0.75 of total which is 0.75x
Now, adding 0.1x + 0.75x would equal 187
0.85x = 187
x = 187/0.85 = 220 trees
The total number of trees is 220.
The number of gala trees is thus 220 - 187 = 33 trees
