The population of a town was 89,443 in 1990 and then has increased at a rate of 0.6% per year since then. which function represents the town's population t years after 1990?

Step-by-step explanation:

In this problem we have a exponential function of the form

where

f(t) is the population of a town

t  is the number of years since 1990

a is the initial value

b is the base

r is the rate

b=(1+r)

we have

substitute

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

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.
