First find the median of ABCD The median is the middle most number. A)3 B) 12,16 sometimes teachers might left you make it 14 but let’s leave it as it is right now. C)1,11 same explanation as B D)6
Now find the mean of each. You find the mean by finding the average. So add up all the numbers in a possible answer and then divide by the number of numbers you added together. That’s confusing so let’s do A together. 2+2+2+3+4+4+4=21 No since I added 7 numbers together to get 21, we divide it by that many numbers. 21/7=3 A)3 B)12.6 C)6 D)5.14
Since A has the same mean and median it will be the correct answer.
First you raise the expressions in the parentheses to their powers. Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases).
