What is the greatest possible error if irina measured the weight of her dog as 13 pounds 0.1 pounds 0.5 pounds 12.5 pounds 13.5 pounds

the correct answer is option B

Step-by-step explanation:

given,

weight of dog = 13 pound

the greatest possible error is half of the measuring unit.

like 1 pound is the smallest measuring unit so the greatest possible error wold be half of that

            greatest possible error =

                                                    = 0.5 pounds

hence, the correct answer is option B which is 0.5 pounds.

- "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."
