========================================================
Explanation:
The observations are in ascending order, which means the set is sorted from smallest to largest.
The X is at the right-most endpoint, so X is the largest value (aka the max).
The min is 33, so,
max - min = range
X - 33 = 58
X = 58+33
X = 91 is the max
The answer is about 2.24 (Hundredths rounded up)
Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.
Horizontal line means that y is a constant. This means the line is y = -6.
