A machine can produce 6 yards of fabric in 2 minutes. If it works at the same rate, how much fabric can the machine produce in 1 and 1/2 hours?

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
