Answer:
we conclude that:

Step-by-step explanation:
Given
We have to determine 
so

Thus we conclude that:

I assume that it is only <span>(f∘g)(x). If not, let me know in the comments
16 + 15x - 65
15x - 49</span>
x = number of hours
want to find probability (P) x >= 13
x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.
P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
To convert that to percentage, multiply 100, to get 84.13%
Answer
I think 55 times
Step-by-step explanation:
13,200/1,200 = 11
5/1200 = x/13,200
so if 1,200*11=13, 200 then 5*11= 55.
btw , could u give me the brainliest if i am right?
Answer:
x = -1
Step-by-step explanation:
1/3(6x-3)+2(x-1) = -7
Distribute
2x-1 +2x-2 = -7
Combine like terms
4x -3 = -7
Add 3 to each side
4x-3+3 = -7+3
4x = -4
Divide by 4
4x/4 = -4/4
x = -1
