Can u guys pls help me on this question and pls explain how u got the answer

192 mm

Step-by-step explanation:

The area of a triangle is 1/2 bh and the base is 8 and the height is 8. 8*8= 64 divided by two is 32. There are four of these sides, so 4* 32 is 128. Then you also have to account for the square bottom which has dimensions of a width of 8 and a height of 8 making the bottom 64. When you add 128 and 64 together you get 192.

Hope this helped  

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
