20% = 20/100 = 1/5
1/5 of 3500
1/5 X 3500/1 = 3500/5
3500/5 = 700.
Answer:
B. 2x-y = 8
Step-by-step explanation:
First, plug in the points (5,2) into the equation. 5 being x and 2 being y.
Then 2x-y = 8
2 (5) - (2) = 8
10 - 2 = 8
8 = 8
Answer:
This is proportional
Step-by-step explanation:
3,5
6,10
9,15
12,20
The x's go by +3
The y's go by +5
Hope this helped!
The z-score is -0.428
<h3>What is a z-score?</h3>
A z-score, also known as a standard score, provides information on how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.
You can plot a z-score on a normal distribution curve.
You must be aware of the mean and population standard deviation to use a z-score.
Z-scores allow results to be compared to a "normal" population.
According to the question,
x=500
μ=533
σ=77
z-score=(x-μ)/σ
On substituting the values,
z-score=(500-533)/77
= -0.428
