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
Answer:
represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.
Step-by-step explanation:
Perimeter is defined as the sum of sides.
For a rectangle having dimension length 'L' and breadth 'B' Since, rectangle has two sides equal.
Perimeter of rectangle = 2 ( length + breadth )
Here, given rectangle has dimension
Length = and breadth =
Thus, perimeter of rectangle =
Thus, perimeter of rectangle is ........(1)
Perimeter of rectangle , when x = 3,
Put x= 3 in (1) ,
Thus, represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.
