Answer:
Inequalities are different from equations. If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.
The definition of mean, is to add up all the numbers and divide it by how many numbers there are. So, in this case the mean would be 1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9 = 86. You would then take 86 and divide that by 21, and you would get 4.0
The definition of median states to find the middle of the numbers. So the median would be 4.
So you would just take 4 - 4 = 0.
0 would be correct.
Answer : E is the answer
Explanation: -2 < n <_ 6
Means the numbers bigger that are bigger than -2 but smaller or equal to 6
And only E matches that
As mentioned mean is b . you multiply it with 8 so the data would 8b.
Answer:
That would be 9 my good sir ( or ma'am )
Step-by-step explanation:
basicly round the 61 so that there would not be a remainder and divide 54 by 6 you will get 9, so therefore the same case is for 540 by 60.
Have a nice day
