So the first one is -0.5 and second is -0.5 the third one is -0.5 and the fourth is -0.25 so I would say that is D
You have to use the Pythagorean theorem because it is a right triangle. Consequently it is the square root of 12 squared plus 17 squared or approximately 20.81
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
