Loss of hearing can be a significant problem for older adults. A home education program has been developed to help people who are receiving hearing aids for the first time. The program emphasizes communication and social skills. To evaluate this program, quality of life scores were measured before the treatment, at the end of the program, and at the 6 month followup. Pls use the data to determine if there was a significant improvement in quality of life following the training program. Quality of life score

- "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."

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184

the answer to that one is b
