The collection would have twelve nickels and nine quarters.
B. Y=4x-14
Think about where the point is on the grid and then use the slope to get to the y-intercept. So for this question your going to have to move backwards to get to the y axis. Move down 12 units and left 3 and that’ll give you the y-intercept which will match in the equation.
Answer:
E(Y) = 1.666667
Step-by-step explanation:
By E(Y), we mean the expected value of Y. This is given as:
E(Y) = ,
Where F is the frequency.
As given:
The sample space (S) = {T,T,H}
And has a probability of:
H = 1/3
T = 2/3.
Frequency:
H = 1
T = 2.
Thus,
E(Y) = 1*(1/3) + 2*(2/3)
E(Y) = 1.666667.
