Answer:

87.9

Step-by-step explanation:

Use a calculator or table to find the z-score that corresponds to 25%.

P(Z < z) = 0.25

z = -0.675

Now find the value that corresponds to that z score.

z = (x − μ) / σ

-0.675 = (x − 101.3) / 19.9

x = 87.9

13 - 3/2<br> Pls give an explanation

postnew [5]

13-3/2 you need to make a common denominator, so

26/2-3/2 then subtract the numerators, the denominator remains.

23/2 now simplify the fraction

11½ this is because 22/2+1/2=23/2, and 22/2=11, so 11+1/2 or 11½
