The probability is 1/1024.
Each tetrahedron has a 1/4 chance of landing on 3, since there are 4 sides and only one of them is marked 3.
Each tetrahedron roll is independent, since no roll is affected by another.
This means we multiply the probabilities:
1/4(1/4)(1/4)(1/4)(1/4) = 1/1024
$1250
Use the formula i = prt
In this case, we don't know P or Principal amount
i = 400
r = .04 *found by diving 4/100*
n = 8
Set formula to solve for P like: P= i/r(n)
P=400/.04(8)
P= 400/.32
P = 1250
To model half-life, use the formula
. Here,
is the amount remaining after a length of time
.
is the amount that you start with.
is the half-life. You plug in 50 for
, 10 for
, and 25 for
. You get
.
The answer is negative. You subtract 730 from 850
8r^6s^3 - 9r^5s^4 + 3r^4s^5 - (2r^4s^5 - 5r^3s^6 - 4r^5s^4) =
8r^6s^3 - 9r^5s^4 + 3r^4s^5 - 2r^4s^5 + 5r^3s^6 + 4r^5s^4 =
8r^6s^3 -5r^5s^4 + r^4s^5 + 5r^3s^6 <==
