Jessica started spending more time on
her math homework, and as a result
her average grade increased from an
82 to an 88 over a 3-week period. to
the nearest tenth of a percent, what
was the percent increase in her
average gade over the 3-week
period
a 93.1%
b 7.3%
c 6.8%
d 6.0%

B. 7.3 %

Step-by-step explanation:

Given:

Initial average grade = 82

Final average grade = 88

Duration for the increase = 3 weeks

Therefore, increase in average grade = Final - Initial = 88 - 82 = 6

Now, percent increase in average grade is given as:

Therefore, the percent increase in her  average grade over the 3-week  period is 7.3 %.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
