How does the amount of principal affect the number of years the rule of 72 predicted in the example of above? And the example above is approximately how long will it take you to double your savings of $500 if you open a CD that earns 4% interest, according to the rule of 72?

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.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

what are ur choices?
