EVERYONE IT'S A TEST! 36 POINTS TO WHOEVER ANSWERS PLEASE HELP!! Mrs. Alberts has taught seventh grade math for thirty years. Every year she calculates and records the class average on the final exam. The following dot plot represents these average scores from the past thirty years.
What percent of the scores lie within one mean absolute deviation (either way) of the mean? Round to the nearest percent and express your answer as a numerical value.
Note: Use the rounded mean and mean absolute deviation.

[ ] %

2

Step-by-step explanation:

89.633333333333

Mean Absolute Deviation (MAD): 2.0755555555556

rounding these both you get 90 and 2.

560

hope this : )

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
