Answer:
57 to 63
Step-by-step explanation:
A suitable probability tool can tell you the limits.
8% of scores will be below 56.95 ≈ 57
76% of scores will be above 63.24 ≈ 63
Scores between 57 and 63 will get a D grade.
The line of best fit helps you make predictions based upon ordered pairs that you have plotted. The independent variable is on the x axis. The dependent variable is on the y axis. You find the slope by plugging in the order pairs into a calculator which gives you the line of best fit.
Hope this helped :)

Answer:
-2018
Step-by-step explanation:
The n-th term is ...
an = a1 +d(n -1)
So, the given terms are ...
-53 = a1 +12d
-128 = a1 +37d
Subtracting the first from the second gives ...
(a1 +37d) -(a1 +12d) = (-128) -(-53)
25d = -75
d = -3
The 668th term will be ...
a668 = a1 +d(668 -1) = a1 +667d = (a1 +37d) +630d
a668 = -128 +630(-3) = -128 -1890 . . . . substitute for a38
a668 = -2018
