Answer:
RANGE: {20.8, 22.4, 25.2, 26.8, 28.4} goes with DOMAIN: {52, 56, 63, 67, 71}
RANGE: {16, 18, 20, 22,24} goes with DOMAIN: {40, 45, 50, 55, 60}
RANGE: {17.6, 20.4, 23.6, 26.4, 29.2} goes with DOMAIN: {44, 51, 59, 66, 73}
RANGE: {14.8, 18.4, 19.6, 22, 22.8} goes with DOMAIN: {37, 46, 49, 55, 57}
Step-by-step explanation:
Circle with center (8,2), radius=3
x=8
y=2
r=3
Let
y------> the total cost
c-----> the number of topping
we know that
----> linear equation that represent the situation
The expected cost is 152
Recall that since Y is uniformly distributed over the interval [1,5] we have the following probability density function for Y
if and 0 othewise. (To check this is the pdf, check the definition of an uniform random variable)
Recall that, by definition
Also, we are given that . Recall the following properties of the expected value. If X,Y are random variables, then
Then, using this property we have that .
Thus, we must calculate E[Y] and E[Y^2].
Using the definition, we get that
Then
(-5,4)
