Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below
Anastaziya [24]

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.

The water level as a river recedes after a flood is measured at regular intervals, and its height relative to normal, in inches,
kicyunya [14]

Answer:

7th measurement = -26

Step-by-step explanation:

The sequence is 16, 9, 2, –5, ...,

First term( a)= 16

Second term=9

Common difference (d) = 9-16

Common difference= -7

The sequence is a arithmetic progression

For AP's ,the terms formula is

Term(n) = a + (n-1)d

Where n represent the term to be found

In this case,we Are looking for the 7th term , so n= 7

Term(7) = 16+ (7-1)-7

Term(7)= 16 +6(-7).

Term (7) = 16-42

Term(7) = -26

7th term =-26
