Answer: C) 50% of the students scored below 70%
<u>Step-by-step explanation:</u>
Mean is the average. To find the mean (aka average) you add up all of the scores and divide by the number of tests.
B) The mean can be 70 without any test scoring 70% so B is not true.
A) Since B is not true, then A is not a valid option.
D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal. Therefore, option D is not true.
C) If the average is 70%, then half received grades above that score and half received grades below that score. So, option C is TRUE!

The x and the y intercept are x = 1.5 and y = -3
<h3>How to determine the x and the y intercept?</h3>
The linear equation is given as:
y + 5 = 2(x + 1)
Set x to 0 to determine the y-intercept.
So, we have:
y + 5 = 2(0 + 1)
This gives
y + 5 = 2
Evaluate
y = -3
Set y to 0 to determine the x-intercept.
So, we have:
0 + 5 = 2(x + 1)
This gives
5 = 2(x + 1)
Evaluate
x = 1.5
Hence, the x and the y intercept are x = 1.5 and y = -3
