Find the​ z-score for which a total probability of 0.86 falls more than z standard deviations​ (in either​ direction) from the mean.

Z-score = 0.1764 ≈ 0.18

Step-by-step explanation:

Z-score for Total probability of 0.86

This can found as shown below

P( Z < -Z ) + P( Z > Z ) = 0.86

= P ( Z < -Z ) + P ( Z < - Z ) = 0.86

=  P ( Z < - Z ) = 0.86 / 2 = 0.43

hence Z-score  = 0.1764  ( from standard Normal table )

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

the answer is 2/54
