Refer to the diagram shown below.
Let the distance that Sassoon travels is d miles.
Let his average speed be x mph.
The time of travel is from 1 p.m. to 4 p.m., which is 3 hours.
Therefore
3x = d (1)
The distance that Archer travels is (d + 300) miles.
The time of travel is from 9 a.m. to 4 p.m., which is 7 hours.
The average traveling speed is (x + 20) mph, therefore
7(x + 20) = d + 300
That is,
7x + 140 = d + 300
7x = d + 160 (2)
Subtract (1) from (2).
7x - 3x = d + 160 - d
4x = 160
x = 40 mph (Sassoon's average speed)
x+20 = 60 mph (Archer's average speed)
From (1), obtain d = 120 mi
Answer:
Archer's speed is 60 mph.
Sassoon's speed is 40 mph.
Answer:
Alright well all you need to do is Graph using the slope and y- intercept so with that the Answer is
Slope: - 2/3
Y- intercept: 7/3 Hope this helps :)

Answer: A. Mean.
Explanation:
Mean is the only measure of central tendency that is always affected by an outlier. Mean, the average is the most popular measure of central tendency.
The mean is strongly influenced by outliers because it is the average of the scores and it is not resistant.
