Choose all that give the correct expression. Steven lost four $10 bills, and now he has −$40.
−4 × 10

If I lose 8 pounds per month for 3 months, my weight will change −24 pounds total.
3 × (−8)

Sarah spends $2 for each fare on the commuter train. She rides the train 10 times during a week.
2 × (−10)

Pat and Amy were on a diet for 4 months. Pat lost an average of 3 pounds a month, and Amy lost an average of 4 pounds a month.
4((−3) + (−4))

The statements that correctly represent the scenario stated are:

B. because losing 8 pounds is represented as -8 and doing this for 3 months would be 3 groups of -8 or 3 x -8

D.  because they showed the weight loss as a negative integer and then put those into groups of 4 each using the distributive property)

The error with the other 2 choices is that the negative number is not correctly representing which part of the problem is a decrease.  The negative sign is placed on the number of groups of.

Step-by-step explanation:

this question is very old so I am just getting point off of it

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

answer is b  

20

hope you get this one right.
