PLEASE ANSWER

Mrs. Mallory and Mrs. Bodine collected data on the science and math final exam scores for a group of students.

What is the best explanation for the cluster of students shown on the graph?

A. No students scored above 90 on both exams.
B. One student scored exactly 60 on both exams.
C. All the students scored between 60 and 100 on both exams.
D. More than half the students scored between 70 and 80 on both exams.

D. More than half the students scored between 70 and 80 on both exams.

Step-by-step explanation:

If we look at choice A:

A. No students scored above 90 on both exams.

This is not true since the graph shows there were students who scored above 90 points on both exams.

If we look at choice B:

B. One student scored exactly 60 on both exams.

This is true but insufficient data since we also have a student who scored 80 points in both  exams.

If we look at choice C:

C. All the students scored between 60 and 100 on both exams.

This is not true since some students scored below 60 points in Math Exam.

If we look at choice D:

D. More than half the students scored between 70 and 80 on both exams.

This is absolutely true since more than half of the total number of dots are concentrated within scores 70 and 80 in both exams.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
