Answer:
Quarters=7
Dime=8
Nickel=2
Step-by-step explanation: 8*.10=.80, 2*.05=.10, 7*.25=1.75 If you add them up you get 2.65.
This is a answer of this question.
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:
0.0622ns
Step-by-step explanation:
Rate, R = 6mm²/s or 6 X 10∧-8m²/s
Radius, r = 109 X 10∧-9m
Area of circular object = πr² = 22/7 X (109 X 10∧-9)²= 3.734 X 10∧-14m²
Speed = 3.734 X 10∧-14m²/(6 X 10∧-8)m²/s = 0.0622ns
