Answer:
A ) 6
Step-by-step explanation:
The formula for Average rate of change is:
Aroc = change in y / change in x.
Aroc = y2-y1 / x2 - x1
The first point will be (x1,y1), and second will be (x2,y2).
x1 is 0, and when the x value is at 0, the y value is at -7, so the coordinate point is (0, -7).
For the second point, x = 2, and the corresponding y value is 5. So you just simpliy plug everything into the formula to find AROC:
= 5 - (-7) / 2 - 0
= 12 / 2
= 6
Answer:
Any number above 85.6
Step-by-step explanation:
To calculate the mean you add all of the scores together then divide by how many scores you added
So in this case you would add 84 + 72 + 90 + 87 + 95 = 428
Then you would Divide 428 by five because you are adding 5 numbers
428/5 = 85.6
It says the score increased so as long as then score is greater than 85.6 it is an option.
