7,8,9,7,2,5,3,2, 2<br><br> Mean__<br> Median__<br> Mode__<br> Range__
serious [3.7K]

Answer:

Mean: 5

Median: 5

Mode: 2

Range: 7

Step-by-step explanation:

We find the mean by adding all the numbers together to get 45. Then we divide the 45 by the amount of numbers in the set, for this one it is 9. 45 divided by 9 equals 5.

To find the median we put the numbers in the set in order from least to greatest. Next, we find the middle number. median=5

To find the mode we find the number repeated the most. In this set the number that repeats the most is 2.

Range is found by subtracting the largest number and the smallest number. 9-2=7

Suppose that 13 inches of wire costs 52 cents. At the same rate, how many inches of wire can be bought for 32 cents?
kirill115 [55]

Answer:

So we have a ratio which you have specified 13:52. So we just need to get the same ratio for 13. 32/52 is how we get 32 from multiplying by 52. So now we just need to multiply it for 13 also'

13*32/52 = 8. Therefore the answer to this is 8
