Answer:
-2
Step-by-step explanation:
Convert the words into a math equation
8n -3 = -19
If you multiply 8 by -2 you get -16
-16 - 3 = -19

Answer:
Median = 6
Mean = 5.44
Step-by-step explanation:
Part 1: Median
So we calculate this problem's median by counting out how many total numbers there are then finding the "middle" number. In this case there are 25 numbers. [(n-1) / 2) +1], Plug 25 in as n --> 24/2 = 12 --> 12 + 1 = 13. =>
So the median of this set would be the 13th number. We can simply count it out and we find that 6 would be the 13th number in this set.
Part 2: Mean
Now we can calculate the mean (average) by adding all the numbers up then dividing by 25 (the amt. of numbers in the whole set). -->
To simply save time, I will just tell you the sum. So correct we if I'm wrong (there are a lot of numbers to add so I might have made a mistake somewere) but I got a total sum of 136 that is not our final answer though because we still need to divide the sum of our numbers by the amt. of numbers in the set (25) =>
136 / 25 = 5.44
And thus, our median is 6, and our mean is 5.44

Jan is not correct. The opposite of any number will not always be a positive. This is because the opposite of a positive number is negative and the opposite of a negative number is positive.
Basically, opposite numbers are numbers that are the same distance to 0 on a number line. If we were to have a positive 1, the opposite of that number would be a -1, because that's equally distant from 0 on a number line.
