Margaret is reading a book. the number of pages she has left to read is 276 - 35d, where d represents the number of days she has been reading. what does each part of the expression represent? (note - not all options may be used) a) the number of pages she has read during 1 week b) the total number of pages in the book c) the number of pages in the book d) the number of pages she has read during d days

Option b , c and d are the part of the expression .

Step-by-step explanation:

We are given that the number of pages she has left to read is 276 - 35d

d represents the number of days she has been reading.

276 denotes the total number of pages

35 pages denotes the number of pages read per day

35 d represents the number of pages she has read during d days

276 - 35d represents teh reamining pages

So, Option b , c and d are the part of the expression .

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.

hope this .
