There are two types of plants in a greenhouse. The following dot plots show the heights of 20 plants, 10 of Type 1 and 10 of type 2. The plants are given the same amount of food and water and grow at the same rate. what is the mean height for each type of plant? Make a comparative inference based on the mean values. ​

she drove 134 miles

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
