Which associations best describe the scatter plot? select each correct answer. linear association negative association nonlinear association positive association scatter plot on a first quadrant coordinate grid. the horizontal axis is labeled time, in minutes. the vertical axis is labeled distance, in feet. points are plotted at (one, fifteen), (two, eleven), (three, eight), (four, six), (five, five), (six, four), (seven, three), (eight, three), (nine, three), (ten, three).

- "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."

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
