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](https://tex.z-dn.net/?f=%5Ctextsf%7BAverage%20of%20Group%20A%7D%3D%5Cdfrac%7B%203%20%5Ctimes%2010%20%2B%204%20%5Ctimes%2011%20%2B%203%20%5Ctimes%2012%7D%7B10%7D%3D11)
![\textsf{Average of Group B}=\dfrac{ 3 \times 9 + 5\times 10+ 2\times 11}{10}=9.9](https://tex.z-dn.net/?f=%5Ctextsf%7BAverage%20of%20Group%20B%7D%3D%5Cdfrac%7B%203%20%5Ctimes%209%20%2B%205%5Ctimes%2010%2B%202%5Ctimes%2011%7D%7B10%7D%3D9.9)
Thus proving that Group A has the longer average former length.

Step-by-step explanation:
We don't know the drivers' names or when or where they started. We have made the assumption that the second equation pertains to Kylie.
Each line is plotted with the appropriate slope and y-intercept. The slope is the coefficient of x, and represents the "rise" for each unit of "run" to the right.
If the sum of their lengths is 5,520 miles then River D is 2360 and River C is 3160
Answer:
f(x)=|x-2|+3
0=|x-2|+3
0-3=|x-2|+3-3
-3+2=x-2+2
-1=x
Step-by-step explanation:
- set the function equal to zero
- you can subtract 3 from both sides or you can add -2 and 3 and then you subtract your answer from both sides to solve for x
