Of course there must, because there aren't 500 different dates in the year to give everybody a different one. There are only 365 different dates.
Answer:
Step-by-step explanation:
A: look at the graph, find the x axis of 2 and on the y axis 1.
B basically the center
C look for x axis of -4, y axis for 3
D x axis -2, y axis -5
E x axis 1, y axis -3
F Center then go up 4
G x axis -5, y axis 1
H x axis -2, y axis 0
Answer: (0, 1) Usually, we put the solutions in parenthesis.
Step-by-step explanation: x(x+1) = x(2) which = x²+ x = 2x = x² + x - 2x = 0
x² - x = 0. Now we divide by x which = x(x - 1) = 0 and the new solution set is x = 0 and x -1 = 0 which equals x = 1
Answer:
For X, the parameter
is λX = 1/2 and for Y it is λY = 1. Using the formula sheet, Mean is
E[Z] = E[X] + 2E[Y ] = 4. Variance is V ar(Z) = V ar(X) + 4V ar(Y ) = 8.
