SOLUTION
The mean is 4min
standard deviation is 1min
the z score is

where

then we have

The probability the call lasted less than 3 min will be
Therefore, the probability that (z < -1 ) is
[tex]\begin{gathered} Pr(z<-1)=Pr(0
Hence, the percentage of the calls that lasted less than 3 min is 16%

Answer:
The answer is 17
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- a² – 4b + 2c
- a = 1, b = (-3) and c = 2
<h3><u>To </u><u>Find</u>;</h3>
- The value of a² – 4b + 2c
Now, Evaluate
a² – 4b + 2c
(1)² – 4(-3) + 2(2)
1 + 12 + 4 = 17
Thus, The value is 17
