Answer: You would get 20 heads and 20 tails.
Explanation: Assuming that the coin is fair which you said it is, then you can also assume that there’s a 1/2 probability of getting heads each time you flip it and tails each time you flip it. So since you flipped it 40 times, you would assume to get heads 20 times and tails 20 times.

<u>SSS rule of congruency</u>
The Side-Side-Side rule of congruency states that if three sides of one triangle are congruent to three sides of another triangle then both triangles are congruent.
To answer this, you use the formula
where
is the simple interest that builds
is the principal (AKA the amount invested/borrowed)
is the interest rate per year
is the lenght of the loan, in years.
In your situation:
![\begin{aligned}I &= (\$3000)(5 \%/\text{year})(3 \text{ years})\\[0.5em]&= (3000)(0.05)(3)\\[0.5em]&= 450\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DI%20%26%3D%20%28%5C%243000%29%285%20%5C%25%2F%5Ctext%7Byear%7D%29%283%20%5Ctext%7B%20years%7D%29%5C%5C%5B0.5em%5D%26%3D%20%283000%29%280.05%29%283%29%5C%5C%5B0.5em%5D%26%3D%20450%5Cend%7Baligned%7D)
This means there'd be $450 of simple interest due at the end of 3 years.
