Find the mean and range.<br><br> 26 19 23 39 31 34 23 25
sveticcg [70]
Range: largest number minus the smallest number
39 - 19 = 20
your range is 20

Mean: add all of the numbers and divide by the amount of numbers there are.

26+19+23+39+31+34+23+25= 220
220/8 = 27.5

your mean is 27.5

hope this helps

How do i multiply fractions
Hatshy [7]
Best Answer:  <span> to multiply fractions you simply take the denominator of both fractions and multiply them, do the same to the numerator, and you have your answer.
ex.
2 5 10
-- * -- = ----
4 8 32

then, of course, you would need to simplify.

so the answer is

10(/2) 5
-------- = -----
32(/2) 16


To multiply mixed numbers, you need to convert them to improper fractions, multiply and then convert them back to a mixed number. For example:
2 1/2 x 5 1/3 = 5/2 x 16 /3

numerator 5 x 16 = 80 denominator 2 x 3 = 6

so now you convert 80/6 into a mixed number

80 / 6 = 13 and 2/6 or, reduced, 13 1/3. </span>

Answer:

<h2>Area = 90 cm²</h2><h2>Perimeter = 53 cm</h2>

Step-by-step explanation:

area and perimeter of the given diagram

<u>area = 1/2 * base * height</u>

where base = 15 cm

        height = 12 cm

plugin values into the formula

area = 1/2 * 15 * 12

area = 90 cm²

<u>Perimeter = add up all sides (AB + AC + BC)</u>

where side BC = √(5² + 12²)

                   BC = 13 cm

Perimeter = 25cm + 15 cm + 13 cm

Perimeter = 53 cm
