Find all values of theta in the interval [0° 360°) that have the given function value.
tan theta = 1

Using equivalent angles, the values of theta are: 45º and 225º.

The answer to your question is: 45° and 225°

Step-by-step explanation:

Getting tan⁻¹ 1 = 45°

Then, the angle we are looking for is 45°, let's check the for quadrangles.

First quadrangle = tan 45 = 1

Second quadrangle = 180° - 45° = 135°      tan 135 = -1

Third quadrangle = 180 + 45 = 225°           tan 225 = 1

Forth quadrangle = 360 - 45 = 315°            tan 315° = -1

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
