Your friend Kara recently decided to start a skateboard business. She just spent $50 on the assembly kit, but she makes $20 in
profit for every skateboard she sells. She's asked you to help her
think about her potential finances for this month. In that time
period, she said she can make 15 skateboards at most.

find the domain and range?

0 is its x and y coordinate

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

- "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."

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
