The cost of High Definition television now averages $1200, but the cost is decreasing by about 15% percent per year. What will the cost be in 7
years? *

The cost in 7 years will be of $384.69.

Step-by-step explanation:

Equation for exponential decay:

The equation for an amount after t years is given by:

In which A(0) is the initial value and r is the decay rate.

The cost of High Definition television now averages $1200, but the cost is decreasing by about 15% percent per year.

This means that . So

What will the cost be in 7 years?

This is A(7).

The cost in 7 years will be of $384.69.

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.

idk this answer sorry cant on this one.
