Answer:
110°
Step-by-step explanation:
92+128 =220
220/2 = 110
The expected value of x is 10.
It is given that the number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).
The expected value of this random variable is n*p = 4*1/2 = 2.
The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable.
Thus E(X) = 5*2 = 10.

Answer:
Parallel sides
Step-by-step explanation:
A rectangle has all of its interior angles equal to each other and inclined at a degree of 90.
The two opposite sides of a rectangle are parallel to each other.
Parallel lines are lines that will never meet, no matter how long that they are extended.
If we can extend the two sides of the rectangle facing each other, we will be able to see that they will never meet no matter how far they are extended.
Thus, the rectangle has 2 pairs of parallel lines
Answer:
15
