Answer:
The correct answer is 30%
In order to calculate the mean (average) you add up all the numbers and divide the total by how many numbers there are.
The sum of the data set is 468.
There are 5 numbers in the set.
468 divided by 5 is 93.6.
The answer is already to the nearest tenth, so the mean is 93.6.
The answer will be D) 4,-6
At least one right angle:
A + C + E
At least 2 sides of equal length:
B + C + E
At least one pair of parallel sides:
A + B + E
Slope = (y2 - y1) / (x2 - x1)
(0,4)...x1 = 0 and y1 = 4
(-8,-1)...x2 = -8 and y2 = -1
now we sub and solve
slope = (-1 - 4) / (-8 - 0) = -5/-8 = 5/8 <=
