The value of a fifth stock, stock E, changed by 2 1/2 times as much as Stocks D. What is the change in value of Stock E?

so what is the question

step-by-step explanation:

i have no clue at all sorry

step-by-step explanation:

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

- "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."
