For every 5 books her students read, mrs. fenway gives them a free homework pass for 4 days. juan has accumulated homework passes for 16 days so far. what proportion would you write to find how many books juan has read?

20 Step-by-step explanation:

16 divided by 4 then multiply 5.

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.
