36 feet rounded to the nearest tenth of a foot

1 answer:

4 0

I don't exactly understand what you're asking, 36 feet does not need to be rounded to the nearest tenth as it is a whole number. Do you mean rounded to 40? (As that would be the nearsest multiple of 10) I'm a bit lost, but hopefully that helps

The two dot plots below compare the forearm lengths of two groups of schoolchildren:

Answer:

Group A, because seven children have a forearm length longer than 10 inches

Step-by-step explanation:

Create the dot plots based on the given information (please see attached images).

Group A = blue dots

Group B = red dots

From inspection of the attached dot plots, we can see that Group A appears to have the longer average forearm length. This is because 7 children have a forearm length of longer than 10 inches.

To calculate the average forearm length, sum all data values and divide by the total number of data values.

$\textsf{Average of Group A}=\dfrac{ 3 \times 10 + 4 \times 11 + 3 \times 12}{10}=11$
