Let p = the number of pennies
let q = the number of quarters
p + q = 23
0.01p + 0.25q = 3.11
Answer:2.a
Step-by-step explanation:
Probability of taking both is the probability of each, multiplied.
.43 x B.E. prob = .062
divide each side by .43
B.E. prob = .144
N = N₀* 
where N is how much you currently have
N₀ is the starting amount
t is the time
and h is the half life of the substance.
F(6)=2
That is because the 6 in the brackets means x
If f(x) means f(6) x=6
And if you look at the graph where the 6 on the x axis is and look where the graph meets the value of 6 it is on the value of 2 on the y axis
