Step-by-step explanation:
For a relation to be a function, every x value must have only one y value. For a, c, and d, some of the x values have multiple different y values
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
36p=5p(7.5)
Step 1: Simplify both sides of the equation.
36p=37.5p
Step 2: Subtract 37.5p from both sides.
36p−37.5p=37.5p−37.5p
−1.5p=0
Step 3: Divide both sides by -1.5.
−1.5p
−1.5
=
0
−1.5
p=0
Good my teacher wasn’t going overboard today
Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15 is 3.
According to the given question.
Tobi scored 145 marks on an iq test.
⇒ x = 145
Mean, μ = 100
Standard deviation, σ = 15
As we know that,
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
And it is calculated by formula
Z = x -μ/σ
Where,
Z is a Z-score
μ is mean
x is the observed value
Therefore,
The Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15
= 145 - 100/15
= 3
Hence,Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15 is 3.
