Answer:

Step-by-step explanation:

there is an obscure rule that looks like this

DB/AB = AB/CB

AB=40 for this problem

DB = x

CB = 20

then

X/40 = 40/20

X = 40(40/20)

X = 40(2)

X=80

I find that hard to believe too,   :D

but the rule says that's right

Considering the given discrete probability distribution, it is found that the expected share is of 10%.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

In this problem, the distribution is given by:

  • P(X = 0.05) = 0.2.
  • P(X = 0.1) = 0.6.
  • P(X = 0.15) = 0.2.

Hence the expected value is given by:

E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.

The expected share is of 10%.

Butoxors [25]
For this case, the first thing we must do is define a variable:
 g: number of gallons of gas.
 c (g): total cost.
 We then have a linear function of the form:
 c (g) = 2.19 * g
 Answer:
 
A function notation to describe the relationship between the total cost c (g) and the number of gallons purchased is:
 
c (g) = 2.19 * g
