What is 9 3/4 - 3 5/9 =

39/4 -32/9

Find common denominators

351/32-128/32

Subtract

223/32

Change to mixed number

223 ÷ 32 = 6 and remainder = 31 =>

223 = 6 × 32 + 31 =>

223/32 =

(6 × 32 + 31) / 32 =

6 + 31/32 =

6 31/32

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
