A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222
sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. \mu=20

\sigma=5

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 22, we have

z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4

Hence, the z score that corresponds to the value x=22 is 0.4

Which of the following functions has the largest value when x = 4?
kotegsom [21]
Answer:The function v(x) has the largest value when x = 4.
Solution:
x=4;
e(4) = 4^2 + 6×4 + 21=16+24+21=61
m(4) = 8×4=32
v(4) = 31×4=124
v(4)>e(4)>m(4)
Therefore,The function v(x) has the largest value when x = 4.
