Answer:
your mom that's what it is
Answer: 61.1
Step-by-step explanation: The answer would be 61.1 because .062 is greater than .05, which means that it rounds up.
The probability that it willtake less than 34 minutes to complete the test is 0.1056
Given mean of 44 minutes and standard deviation of 8 minutes.
We have to find the probability that it will take less than 34 minutes to complete the test.
The probability lies between 0 and 1. The formula to calculate probability is number of items divided by total items but it can also be found through z test calculations.
We are using z test to find the probability.
Z=X-μ/σ
Where μ is sample mean and
σ= standard deviation
Z is z value
First we will find the p value from 34 to 44.
Z=34-44/8
=-10/8
=-1.25
P value for X<34=P(Z<-1.25)
=0.5-0.3944
=0.1056.
Hence the probability that it will take less than 34 minutes is 0.1056.

How you start the equation is by plugging
3
into both of the
x
's in the problem to make it:
f
(
3
)
=
3
(
3
)
−
4
Next, you multiply the
3
(
3
)
to get
9
and subtract
4
. So in the end, you leave the
f
(
3
)
and
9
−
4 is
5
, so the
y
in the equation is
5
.
The answer would be written as
f
(
3
)
=
5
