There are 100 tiles that were purchased to raise money for a new playground. The tiles will be laid along a walkway. Each tile is 4.75 inches wide. If the tiles are going to all be lined next to each other, how many inches long will they cover along the walkway? (I think it's 475)

Step-by-step explanation:

You are right

Step one:

we are told that the total number of tiles is 100 in number

since each tile has a lenght of 4.75 inches each

a way to this is to add 4.75+4.75+4.75+ in a hundred places to find the lenght.

Step two:

Another way is to multiply 4.75 by 100 which is

=4.75*100= 475 in

Hence the tile will cover 475 inches along the way

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.
