Answer:
E(X) = 17.4
Step-by-step explanation:
We can calculate the expected value of a random X variable that is discrete (X takes specific values ) as:
E(X) = ∑xp(x) where x are the specific values of x and p(x) the probability associated with this x value.
In this way the expexted value is
E(X) = ∑xp(x) =(16*0.6)+(18*0.3)+(20*0.2) = 8+5.4+4 = 17.4
Answer:
y=x^2 is not a linear function
Step-by-step explanation:
Answer:
Step-by-step explanation:
The figure is a parallelogram. That means the y value of g is the same as the y value of H
G( ? , b)
The x value of G is a little harder. You have to be careful what you do to c.
A is at - c which means you need to add c to get to (0,0)
In addition, you go out d units to get to F. So the x value of G = c + d
the complete answer is G(c + d,b)
Answer:
288 miles
If we have the distance, we divide by 36 instead to find how many gallons of gas he used.
Step-by-step explanation:
180/5=36 miles per gallon
8 gallonsx36 miles per gallon=288 miles
