Answer:
0.789
Step-by-step explanation:
First, find the expected value (the mean).
μ = ∑ x P(x)
μ = (0) (0.359) + (1) (0.436) + (2) (0.180) + (3) (0.025)
μ = 0.871
Next, find the variance.
σ² = ∑(x − μ)² P(x)
σ² = (0 − 0.871)² (0.359) + (1 − 0.871)² (0.436) + (2 − 0.871)² (0.180) + (3 − 0.871)² (0.025)
σ² = 0.622
Finally, find the standard deviation:
σ = √0.622
σ = 0.789
3.5 years (so 4 years)
2500×0.065 (this gets the amout earned per year) =162.5
568.75÷162.5 (how many years to get the desired amount) =3.5

Graph :
Choose any two points. (0 , 2) and (-1 , -2)
Rate of change = Change in y ÷ Change in x
Table:
Rate of change = ![\frac{-2-[-6]}{2-0}](https://tex.z-dn.net/?f=%5Cfrac%7B-2-%5B-6%5D%7D%7B2-0%7D)
