8. find the product of 8 ∙ 93 mentally using the distributive property. 11. find the median of the set of data: 61, 40, 65, 48, 64, 57, 64, 42, 56, 55 12. find the value of the expression 8(3 − 4) + 5.

8. First, you would want to multiply 8 and 90. That would be 720. Then, you would multiply 8 and 3. Which would be 24. Finally, you would add those two numbers. Giving you 744.

11. 56.5. The median is the middle number in the data. Since it was between 56 and 57, that would put it in the middle,

12. -3

(8) 8*90+8*3=720+24=744

(11) sort the list:

{40, 42, 48, 55, 56, 57, 61, 64, 64, 65}

since the list has an even number of elements

take the two from the center and average them to get the median:

(56+57)/2=113/2=56.5=median

(12) 8(3-4)+5=8(-1)+5=-3
