The correct answers are A and E.
The mean is affected by outliers.
It a data set is skewed to the right, the mean will be larger than the median because the median is in the middle so will fall in the lower range while the mean is an average of all of the values, so the skewness pulls the mean toward the right, toward higher values.
First you need to simplify the equation.
y + 3 = 2(x - 1)
y + 3 = 2x - 2
Then you need to put that into slope-intercept form (y = (slope)x + (y intercept))
y + 3 = 2x - 2
-3 -3
y = 2x - 5
The slope is the coefficient of x, so 2 is the slope of the line.
The answer is 3/22

Answer:
23/20
Step-by-step explanation:
2/5+3/4
=8+15/20
=23/20
The two ends of the track are semi circles, so we need to calculate the circumference:
Circumference = PI x 56 = 175.84
The two straight parts are 130 m each:
Total perimeter = 175.84 + 130 + 130 = 435.84 m
The answer is D.
