Mr. Gray's quiz was normally distributed with a mean of 25 and a standard deviation of 10. Find z-scores for each of the following data values a. 40
b. 27
c. 6

a. 1.5

b. 0.2

c -1.9

Step-by-step explanation:

The computation of the z scores of each of the following data values are as follows:

As we know that

z = (data values - mean)÷ standard deviation

Now

a. The z value is

= (40 - 25) ÷ (10)

=  1.5

b. The z value is

= (27 - 25) ÷ 10

= 0.2

c. The z value is

= (6 - 25) ÷ 10

= -1.9

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!
