Answer:
61.2 degrees
Step-by-step explanation:
You want to isolate x on one side of the equation and the numbers on the other side
3x + 2x + 27 = 180
3x + 2x +27 - 27 = 180-27
5x = 153
x = 153/5
x = 30.6
<DOC = 2x
2x = 30.6 x 2
61.2 degrees
Answer:
E(X) = 17.4
Step-by-step explanation:
We can calculate the expected value of a random X variable that is discrete (X takes specific values ) as:
E(X) = ∑xp(x) where x are the specific values of x and p(x) the probability associated with this x value.
In this way the expexted value is
E(X) = ∑xp(x) =(16*0.6)+(18*0.3)+(20*0.2) = 8+5.4+4 = 17.4
