Answer:
19 is the third number.
Step-by-step explanation: To find the mean you need to add all of the numbers up then divide it by how many numbers there are. Since the mean is 10 and there are 3 numbers, I know that the numbers have to sum up to 30, and since 7+4=11 then I know to make the sum 30 I need 19 more. So the third number in your data set is 19.
There are 5 20% in 100% ( 20 x 5 = 100)
So 10% of a number would be 12 x 5 = 60
Then there are 10 10% in 100% ( 10 x 10 = 100).
So if 10% = 60, then 100% = 60 x 10 = 600.
The starting value is 600
600 x 10% = 600 x 0.1 = 60
60 x 20% = 60 x 0.2 = 12
Now you have the starting value you can calculate the other answer:
600 x 20% = 600 x 0.20 = 120
120 x 10% = 120 x 0.10 = 12
The answer would be 12
(-5,0) (3,0) bc it factors into (x+5)(x-3) and set both equal to zero to get -5 and 3
