Assume x is a normal random variable with mean 20 and variance 16, and y is a gamma random variable with parameters 5 and 2. in addition x and y are independent. construct a box with length l = |x|, width w = 2|x|, and height h = y . let v be the volume of the box. calculate the expected value e[v ]?

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.
