Tom built a rectangular prism with a length of 8 cubes, a width of 6 cubes, and a height of 4 cubes. Which expression would be used to find the volume of Tom's cube? A 8 • 6 • 4

B (2 • 8 • 6) + (2 • 8 • 4) + (2 • 6 • 4)

C 2 • 8 • 6 • 4

D 8 + 6 + 4

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

the answer is b.)

< 1=< 2

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
