If a hummingbird were to get all of its food from a feeder, then a 16 ounce nectar feeeder could feed about 80 hummingbirds a day. how many hummingbirds would you expect to be able to feed with a 12 ounce feeder

Set it up as a ratio:

16 ounces feeds 80, 12 ounces feeds X

16 / 80 = 12 / X

Cross multiply:

16X = 80*12

16X = 960

Divide both sides by 16:

X = 960 / 16

X = 60

12 ounce feeder will feed 60 hummingbirds.

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.
