The population of a town can be modeled by the regression equation y = 20,000(1.03x). Which is the best prediction for the popul

bixtya [17]

Answer:

The best prediction for the population in year 25 is $41,876\ people$

Step-by-step explanation:

we have a exponential function of the form

$y=a(b^{x})$

where

a is the initial value

b is the base

In this problem

$a=20,000\ people$

$b=1.03$

$b=1+r$

$r=b-1=1.03-1=0.03$

$r=3\%$

so

$y=20,000(1.03^{x})$

For $x=25\ years$

substitute

$y=20,000(1.03^{25})$

$y=41,875.56\ people$

Round up

$y=41,876\ people$

Ms. Banerjee bought a car for $22,500. The amount she paid for her new car was twice the amount she paid for her previous car, w

bagirrra123 [75]

You didn't say if the car bought is the new car or the old car so I'm assuming the car bought for $22,500 is the new car.

You divide 22,500 by 2 to get the cost of the old car. When you do this, you find out the old car costed $11,250.

the equation is 22,500/2=p

If $22,500 is the cost of the old car, then it's not my fault that the poster did not make it clear. If the previous car costed $22,500, then the previous car costed $22,500
