Answer:
2 and 5 for sure. I think 4 is correct, but your teacher may not.
Step-by-step explanation:
The given expression reduces down to -7m - 8 = m - 4
1 cannot give -15m on the right. One seldom sees that mistake on Brainly.
3 does not do that. - 3m is not - 7m
4 has it's sides reversed. I would count it is right, others may not. I'm trying to say the left side is on the right side and the right side is on the left. That to me is OK.
5 is Ok as well the left is written as -8 - 7m which is -7m - 8. and with -4 and m
6 has been reduced on the left incorrectly. the right is it's signs backwards
2 4(?) and 5
-2x-11 because you distribute the negative to everything in the parentheses and then combine like terms
The standard deviation of the numbers 14 22 6 9 11 23 15 18 20 12 is 5.67646 the mean is 15 and the standard deviation variance is 32.222.
Answer:
Step-by-step explanation:
Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.
= 
We then multiply by -1 to (3/7)^3 to get the exact answer.
