Meghan has 5 1/4 yards of fabric. she plans to use 2/3 of the fabric to make 4 identical backpacks. to find how much fabric she will use to make the backpacks, meghan multiplies 5 1/4 by 2/3. what else does meghan need to do to find out how much fabric she needs for each backpack?

Answer and explanation:

Megan also needs to divide what 5 1/4 x 2/3 equals by 4.

Do keep, change, flip (kcf)

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.

they used 313 gallons of paint
