Answer:
5. C - 180ft²
6. D - 120m³
Step-by-step explanation:
5.
(6.5 x 11) = 71.5
(6 x 2.5) = 15
(6 x 11) = 66
(2.5 x 11) = 27.5
6.
((7.5 x 4)/2)(8) = 120
Answer: 14
Step-by-step explanation:
Since they said find the mean
You are suppose to add up all the numbers then divide it by how many numbers are there.
The first one is 156, the second 420 the third is 6,138 and the forth one is 64.
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
