1,12/ Not a solution
2,10/ solution
4,5/ solution
6,10/ not a solution
12,8/ not a solution
18,6/ not a solution
Step-by-step explanation:
all you have to do is put it into the equation.
for example:
1,12
1x1+12x3= $37

The z-score of the number of teens that transfered schools is the standard score
The obtained value of z is 5
<h3>How to determine the value of z?</h3>
The given parameters are:
- Population mean, μ = 50
- Population standard deviation, σ = 10
- Sample, x = 100
- Sample mean = 59
The z-value is calculated using:
z = (x - μ)/σ
Substitute known values in the above formula
z = (100 - 50)/10
Evaluate the difference
z = 50/10
Evaluate the quotient
z = 5
Hence, the obtained value of z is 5
