The box plots show the math scores of students in two different classes: Class A
Class B
50
55
60
65
70
75
80
85
90
95 100
Based on the box plots, which statement is correct?
• The median score of Class A is greater than the median score of Class B.
O The lower quartile of Class A is greater than the lower quartile of Class B.
O The upper quartile of Class A is greater than the upper quartile of Class B.
• The maximum score of Class A is greater than the maximum score of Class B.

step-by-step explanation:

- "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."

step-by-step explanation:

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.
