3m^3 -2m^2 + 4m + 2
To factor the first problem you have to divide all by 4
The second one is m - <span>√16m +8
To factor the second problem you have to square root it all</span>
20%, because if 65 is 100, then 52 is 80% out of 65; so 100 - 80 is 20
Answer: either of two angles whose sum is 180°.
Step-by-step explanation:
To find the standard error, divide the standard deviation by the square root of the sample size
standard deviation = 7.5
sample size = 25......sqrt 25 = 5
standard error = 7.5 / 5 = 1.5 <==
