<span>This would be a bell curve with a z-score of greater than +2.00, since 3 minutes is exactly two standard deviations greater than the mean of 2.00. Looking at a z-score table for the proportion of the curve that lies in the 1-tailed area greater than 2.00, we find that the value is .0228. This would be the probability that the conversation is over three minutes: 0.0228 or 2.28%.</span>

Step-by-step explanation:

Actually Welcome to the Concept of the Functions.
Let's first find the g(-1),
so we get as
3(-1)^2 +5(-1)-6
=> 3 -5-6
=> -8
now since g(-1) =-8
let's find f(g(-1)) that is f(-8)
f(-8) = 4(-8) + 14
=> f(g(-1)) = -32+14
=> f(g(-1)) = -18
-18 is the answer.
Answer: (C) $104
<u>Step-by-step explanation:</u>
The Annual Expenses are:
- Car Insurance = $850
- <u> Books </u>= <u>$400 </u>
Total = $1250
There are 12 months in a year so divide the Annual Expense by 12:
<u> 1 0 4</u>
12 ) 1250
<u> -12↓↓ </u>
5↓
<u> - 0↓ </u>
50
<u> - 48 </u>
