On the graph below, find point (20, 200). Label it A. Next find point (40, 400). Label it B. Dawa dotted line from point A along the 200 km line to the 40 s line. Next, draw a dotted line from
point B along the 40 s line to the 200 km line. Use this graph to solve for average speed.
a. Difference in distance between points A and B

b. Difference in time between points A and B

c. Average speed =

d. Average speed = Km/s

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
