The answer is y=-1/2x+4 that is if you are finding y. But if you are finding x it is x=-2y+8.
Answer:
187237575
Step-by-step explanation:
Here is the equation to solve the problem above:
f(x) = (7-x)^3
y = (7-x)^3
switch y and x
x = (7 - y)^3
third root of x = 7 - y
-y = 3rootx - 7
so:<span><span>f′(x)=3^<span>√x</span>−7</span></span>
X intercept is where x=0
y intercept is where y=0
Answer:
3.9
Step-by-step explanation:
Given the data:
Payout ($) (x) : 0 2 4 8 10
Probability p(x) : 0.35 0.2 0.1 0.2 0.15
The expected winning ; E(X) = Σ(x * p(x))
Σ(x * p(x)) = (0*0.35)+(2*0.2)+(4*0.1)+(8*0.2)+(10*0.15)
= 0 + 0.4 + 0.4 + 1.6 + 1.5
= 3.9
