Dion can type 155 words in 6 minutes. Assuming that he can type at a constant rate, about how many words can Dion type in 45 minutes?

1162.5 words

Step-by-step explanation:

6m = 155 words

45m = × 155 words

        = 1162.5 words

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.
