On the production line the company finds that 90.2% of products are made correctly. you are responsible for quality control and take batches of 30 products from the line and test them. what number of the 30 being incorrectly made would cause you to shut down production? (a) less than 25 (b) less than 28 (c) less than 26 (d) less than 24

- "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."

the correct answers i think are b. and d.

give me brainliest if it is correct!
