Answer:

"differential selection"

Step-by-step explanation:

If your friend took the test twice and passed both times with a score above 90% then the minor difference in price is most likely due to "differential selection". The first test had  questions that he had a little more experience in solving, while the second time he was most likely given a couple questions that he wasn't as prepared for as he was the first time. This is most likely the cause for the difference in percentiles.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Parallel to y=2x+1<br> Goes through (5,4)
Ket [755]
      y = mx + b
      y = 2x + 1
y - y₁ = m(x - x₁)
y - 4 = 2(x - 5)
y - 4 = 2(x) - 2(5)
y - 4 = 2x - 10
  + 4          + 4

Pls help me! I'm confused
zepelin [54]
The question is asking you to organize the data in line plot form. to do so you must create a number line (which in this case is provided for you) and put X's above the numbers. for example lets say your given the following data :
1, 2 ,2 , 4 , 1 , 3 , 2 , 5 
this is how you would graph it in line plot form 



x .      x
x .      x .           x .         x .          x

_________________________________________
1 . . .   2 .          3 .         4 .          5
  
but in your case not al the numbers listed are on the plot so instead you do this:
x .    x
x .    x .      x .      x .        x
___________________________________
1 .              3 .                5 . 
plot as if the numbers are there. ( as usual spacing is important)
