What percent of 128 is 32
bija089 [108]
We can set up a proportion.

32/128 = x/100

32 * 100 = 3200
128 * x = 128x.

Now we have 128x = 3200.

All we need to do is divide 3200 by 128, so 3200 / 128 = 25, so your answer is 25%.

over a two week period Julie had the following number of math homework problems given each day:20,0,7,10,11 0,25,15,1 find the m
kvv77 [185]
Mean: Add all the numbers and divide by the amount of numbers.

20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)

Mean = 9.889 (rounded)

Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25

The middle number is 7

Median = 7

Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers

Range: Subtract the greatest number with least number

25 - 0 = 25

Range = 25
