a. (b) 2.5
b. (b) 1.89
Step-by-step explanation:
E(X) =0(0.05)+1(0.25)+2(0.35)+3(0.15)+4(0.15)+5(0.15)= 2.5
Make a box putt the 70% at the top on the ouside then sub 100%-70% the box should have 4 squares so then on the bottom of the box on the outside. it should be 30% then in the top left corner put 28 and under it 46 then do

The answer would be C
Step-by-step explanation:
The only logical reason would be positive because the parabola is opening up. The average rte of change is opening 0.5 per square
I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.
