The z-score for 81 is 1.75

<h3>How to determine the z-score for 81?</h3>

The given parameters are:

μ = 60 , X=81, and σ = 12

The z scores is calculated using:

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

Substitute the given values

z = \frac{81 - 60}{12}

Evaluate the difference

z = \frac{21}{12}

Simplify

z = 1.75

Hence, the z-score for 81 is 1.75

PLEASE HELP!!!! Find the value of -7 - 8 - (-8) - 7. 0 14 -14 -30
miskamm [114]

-7 - 8 - (-8) - 7 × 0(14) - 14 - 30

(I think that's what that says)

Do PEMDAS

0(14) = 0

-7 × 0 = 0

You're left with -7 - 8 - (-8) - 14 - 30

Go from left to right

-7 - 8 = -15

-15 - (-8) = -7

-7 - 14 = -21

-21 - 30 = -51

alekssr [168]

Answer:

Step-by-step explanation:

Given

Joaquin's score is 75,72,85,62,58,91

and Trisha's score is 92,90,55,76,91,74

Arranging score in order of value we get

Joaquin's : 58,62,72,75,85,91

Trisha's : 55,74,76,90,91,92

as no of values is even therefore their median is

Joaquin's=\frac{72+75}{2}=73.5

Trisha's =\frac{76+90}{2}=83

Therefore median of Joaquin's is lower

Thus Joaquin wins the game
