Which numbers complete the blanks when solving the equation cos(x+2pi)= -(square root of 2/2) over the interval [0, 2pi]?

1, 0

Step-by-step explanation:

Let . From Trigonometry we remember the following identity:

(Eq. 1)

Where and  are angles measured in radians.

Then, we proceed to expand the given expression:

Therefore, correct answer is "1, 0".

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
