The z-score of Kimmie is -0.625
<h3>Calculating z-score</h3>
The formula for calculating the z-score is expressed as;
z = x-η/s
where
η is the mean
s is the standard deviation
x is the Kimmie score
Substitute the given parameter
z = 85.9-88.4/4.0
z = -2.5/4.0
z = -0.625
Hence the z-score of Kimmie is -0.625

Answer:
-42+10i
Step-by-step explanation:
*start with the square roots
\sqrt{-25} \\ =5i
\sqrt{-100} \\ = 10i
*then insert values
(2+5i)(4-10i)
*Use FOIL to multiply
2x4 + 2x-10i + 5ix4 + 5ix10i
*Simplify
8-10i+20i+50i(squared)
*Add like terms
-42+10i
*( i squared = -1 )
