Answer:
Nico
Step-by-step explanation:
In order to compare who had the best performance on the aptitude test, we can use Z score. Z score indicates how many standard deviation a result is over the mean. For this case the higher the result is, the best is the performance on the aptitude test.
Z score is expressed with the following formula:
Z=(X-μ)/σ
Where:
X is the test score
µ is the mean
σ is the standard deviation
Replacing in the formula we obtained
For Nico:
X = 88.3
µ = 66.2
σ = 13
Z=(88.3-66.2)/13=1.7
For Justin:
X = 226.2
µ = 216
σ = 17
Z=(226.2-216)/17=0.6
For Tera:
X = 7.97
µ = 7.2
σ = 0.7
Z=(7.97-7.2)/0.7=1.1
Nico had the higher Z score which means he had the better performance on the test and he should be offered the job.

hey try taking a picture of the question on photo math! helps me alot
Answer:
The answer x=13 or x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
|x−7|=6
Solve Absolute Value.
|x−7|=6
We know eitherx−7=6orx−7=−6
x−7=6(Possibility 1)
x−7+7=6+7(Add 7 to both sides)
x=13
x−7=−6(Possibility 2)
x−7+7=−6+7(Add 7 to both sides)
x=1
Answer:
x=13 or x=1
