The answer is the mean is 8. The range is equal to the largest number, 10 minus the smallest number, 5. It equals 5, so d is wrong. The mean is all of the values added together, 80, divided by the number of values, 10. So, 8. The median is the middle which is between 7 and 8, so 7.5. Five has no dots.
Answer:
Step-by-step explanation:
1)
y is 3 times more than x.
X=0 Y=0 3x0=0
X=1 Y=3
X=2 Y=6
X=3 Y=9
X=4 Y=12
Then just plot it as co-ordinates (x,y)
2)
Y is 1/4 of x. Divide by 4
X=0 Y=0
X=4 Y=1
X=8 Y=2
X=12 Y=3
X=16 Y=4
Then just plot it as co-ordinates (x,y)
D- all 4 sided have at least one pair of parallel sides
