Answer:

930

Step-by-step explanation:

1) Once upon a time there was a bored kid in class who invented a super cool formula

This formula goes like this:

n(n+1)

where n= the sum of the first n numbers in a series

so

30(30+1)=30(31)=930

930

1. 3x - 2y = 8 Subtract 3x on both sides

-2y = 8 - 3x Divide by -2 on both sides to get y by itself

y = -4 + 3/2x


2. a + b / 3 = 5 Multiply 3 on both sides

a + b = 15 Subtract a on both sides to get b by itself

b = 15 - a


3. 12x - 4y = 20 Subtract -12x on both sides

-4y = 20 - 12x Divide -4 on both sides to get y by itself

y = -5 + 3x


4. y + 3 = -5(x - 2) Multiply -5 to (x-2)

y + 3 = -5x + 10 Subtract 3 on both sides to get y by itself

y = -5x + 7

The outlier is the number that’s farther away from the others, in this case it’s 9. The mean is the average of all the data points so it is 77/20 or 3.85. Finally, the range is the highest number minus the lowest number, so the range is 8.
