Step-by-step explanation:
Given - Aiden has two toy cars that measure two and one fourth inches,
three that measure two three eight inches, one that measures two
and seven eights inches, one that measures 2 and one eights
inches, and one that measures two and three fourths inches.
To find - How long is Aiden's longest toy car.
Proof -
Measure of 1st car - 2 inches
Measure of 2nd car - = 0.25 inches
Measure of 3rd car - = 2.375 inches
Measure of 4th car - = 2.875 inches
Measure of 5th car - = 2.125 inches
Measure of 6th car - = 2.75 inches
So, the longest toy car length is (2.875 inches )

The two dot plots are missing, so i have attached it.
Answer:
The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles
Step-by-step explanation:
From the attached image, we are told to compare the means for each plot to the nearest tenth.
Mean = Σx/n
Now, from the image, total number of miles run by the 14 students at the beginning of the school year is;
(1 × 7) + (2 × 8) + (4 × 9) + (4 × 10) + (2 × 11) + (1 × 12) = 133
Mean of miles run at the beginning of the school year = 133/14 = 9.5 miles
Again, from the table, total miles run at the end of the school year = (2 × 8) + (2 × 9) + (4 × 10) + (3 × 11) + (3 × 12) = 143
Mean of miles run at the end of the school year = 143/14 = 10.2 miles
Thus;
The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles
