That would be 6/15 well if you multiply i does make sense well in my head i already got the same answer tho so its right
Answer:
a) median= 25 mins
interquartile range= 19mins
b) the braineys
, because the braineys took 32mins on average and the cleverites took 25 mins on average which is 7 minutes more.
Step-by-step explanation:
a) find the median by going across the middle of the cumulative frequency (in this case, 40) until it hits the line (the cleverites) and move down to see the time in minutes. 25 mins.
to find the interquartile range, first find the lower quartile. So find the half of the median, or the quarter of the cumulative frequency ( 20) and go across until it hits the line and look down from that point to find the time ( 15 mins). Then, find the upper quartile by finding 3/4 or half+quarter of the cumulative frequency (60) and do the same with the line (34mins)
the interquartile is upper quartile - lower quartile
34-15= 19 mins
interquartile= 19 mins.
b) the average is the same as the median, so find the median for the cleverites and the median for the braineys, which is 25 mins and 32 mins, therefore the braineys took longer, thus was the slowest at completing the test on average.
Yes, the expression to answer that is 1,000 divided by, the answer is 125.
There is 5280 feet in 1 mile
5280 x 10 = 52800
52800 ft is your answer
hope this helps
Answer:
slope intercept form: y=1/2(x)+7
Step-by-step explanation:
slope intercept form is written as y=mx+b
on a graph, the equation y=8y-4x=56 goes through the "x" axis at point (-14,0) and the goes through the "y" axis at point (0,7)
