equivalent expression to 8b + 8 - 4b + 3. b= -2 then give evidence that he expression is equivalent to the orginal problem by equivalating b = -2

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

maya’s expression will generate the wrong sum because she violated the commutative property.
