Answer:
I think it is 370
Step-by-step explanation:
The equation in its standard form is written as followsax ^ 2 + bx + c = 0
To find the values of a, b, c we must compare the given equation with the standard equation. Comparing we have:
ax ^ 2 + bx + c = 0
1 / 4x ^ 2 + 5 = 0
Therefore the values of a, b, c are
a = 1/4
b = 0
c = 5
The variable is x.

Answer:
The probability is 2/5 that a $20 bill will be drawn from the wallet.
Step-by-step explanation:
There are 20 total bills in the wallet (5 $5, 7 $10, and 8 $20, 5+7+8=20). So if the finder and returner of the wallet was to be given one of the bills drawn from the wallet there would be an 8/20 chance the owner of the wallet would pull a 20. That's because there are 20 total bills in the wallet and 8 of them are $20.
Simplifying 8/20... 8/20= 4/10= 2/5.
So, there is a 2/5 chance that a $20 bill will be pulled out of the wallet.
Hope this helps!
