Answer:
5 1/4
Step-by-step explanation:
Subtracting a negative is the same as adding a positive.
2 3/8 - (-2 7/8) =
= 2 3/8 + 2 7/8

Okay so median is the number in the middle and mean is when you add them all up and divide by how many numbers there are
<span>20,28,35,40,132
So 35 is the median
and the mean is </span>20 + 28 + 35 + 132 + 40 = 255 / 5 = 51
the mean is a better way to represent the data because it does not just pick a number from the set of numbers it calculates the average
9514 1404 393
Answer:
13 cm, 39 cm, 39 cm
Step-by-step explanation:
If x is the short side, then the other two sides are 3x and 3x. The perimeter is the sum of side lengths:
x +3x +3x = 91
x = 91/7 = 13
3x = 3(13) = 39
The length of the short side is 13 cm; the other two sides are 39 cm.
