Answer:
the probability that the song should be played on accurately 3 days out of 5 days is 0.051
Step-by-step explanation:
Given that
The probability that a particular song is played is 1 by 5
We need to find out the probability that the song should be played on accurately 3 days out of 5 days
So,
= 0.051
Hence, the probability that the song should be played on accurately 3 days out of 5 days is 0.051

The first statement "<span>y varies directly as x" means that as y increases, x also increases. To help us we need to assign a proportionality constant, k. We can now say:</span>
y=kx where k is just a constant. Then substitute the values,
180=kn
n=5k
With these equation we know that k is equal to (positive or negative) 6 and therefore we can get n to be (positive or negative) 30.
Answer:
3x - 3
Step-by-step explanation:
(x + 4) + (2x - 7) =
The first step is to drop the parentheses since they are unnecessary.
= x + 4 + 2x - 7
Now group like terms together.
= x + 2x + 4 - 7
Combine like terms.
= 3x - 3

This problem is really simple as you would plug in what's given to you.
So g would be 1.2, so you would subtract 1.6 - 1.2
Your answer would be 0.4
