Its super easy all u have to do is go on tiger math and the first link will take you to it and u put in the question and it will give you a step by step how to do it and it will give you the answer
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.


Thus proving that Group A has the longer average former length.
<em>3.250 x 10^4, </em><em>will be the correct answer.</em>

because 4(a-3) what’s in () can’t be done so you go to the next step in pemdas and multiply and then you write it out and your done
Multiply numerator and denominator by the same number - 50/100.
