If your scientific investigation is not testable, is it still scientific?? *

The scientific method, it could be said, is a way of learning or a process of using comparative critical thinking. Things that are not testable or falsifiable in some scientific or mathematical way, now or in the future, are not considered science.

Explanation:

In other words, It Isn't scientific. I'm not sure, but I hope this helps.

No

Explanation: To have a scientific investigation your experiment needs to be testable and if it is not testable then its not a scientific investigation.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

c should be the answer
