(8,7, 4,4,2)

Mean__
Median__
Mode__
Range__

mean=5,median=4,mode=4,range=6

Step-by-step explanation:

arrange these numbers in order

2,4,4,7,8

to find mean, you have to add up all of the numbers and divide by the amount of numbers there are.

all of them added together is 25. because there are five numbers, 25divided by 5 is well... 5

median is picking the number smackdab in the middle in this case, it would be 4, because 4 is right there.

mode means most common. because four is the only one that appears twice, 4 would be the mode

Range is the difference between the lowest number an the highest number. In this case, 2 and 8. 8-2=6 so range is 6

109 trust me

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
