Answer:
The answer to your question is ∠3 = 24°
Step-by-step explanation:
Data
∠4 = 11x
∠3 = 4x
Process
1.- From the picture, we know that angles 3 and 4 are complementary so if we sum them up the result is 90°.
∠3 + ∠4 = 90°
2.- Substitution
4x + 11x = 90°
3.- Simplification and result
15x = 90°
x = 90/15
x = 6
4.- Find angle 3
∠3 = 4(6)
∠3 = 24°
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
