Nate borrows $300 to buy a smartphone. He is charged 5% simple interest per year. How much interest, in dollars, will Nate pay after 2 years?

He is charged 5% simple interest per year. How much interest, in dollars, will Nate pay after 2 years? The interest after 2 years will be 0.05*300*2 = 30 dollars.

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.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
