A closed circle means that value is included, and an open circle means that value is excluded.

Example:

x > 2 ---- Graphed with an open circle, everything greater than but not including 2

x ≤ 3 ------ Graphed with a closed circle, everything less than and including 3

Student Life Insurance Company wants to offer an insurance plan with a maximum claim amount of $5,000 for dorm students to cover
shusha [124]

Answer:

25 = 0.01*5000 - X* 0.99

And now if we solve for X we have this:

0.99 X = 50-25 =25

X= \frac{25}{0.99}=25.25

So then we conclude that they should be charge $25.25 for the insurance in order to have a profit of $25.

Step-by-step explanation:

Previous concepts

In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".

For this case we can use the definition of expected value given by:

E(X) =\sum_{i=1}^n X_i P(X_i)

Solution to the problem

For this case we know that the probabiity of maximum claim is 0.01, so then the probability of no maximum claim by the complement rule is 1-0.01=0.99

And we know that the plan with maximum claim gives an amount of $5000

Let X the charge for the premium insurance

We also know that the profit or the expected value would be 25 for the company

If we apply the concept of expected value we have this:

25 = 0.01*5000 - X* 0.99

And now if we solve for X we have this:

0.99 X = 50-25 =25

X= \frac{25}{0.99}=25.25

So then we conclude that they should be charge $25.25 for the insurance in order to have a profit of $25.

1/5x-2/3y=30 when y=15
dolphi86 [110]

Answer:

Step-by-step explanation:

<u>Step 1:  Set y to 15 and solve</u>

<u />\frac{1}{5}x - \frac{2}{3}*15=30

\frac{1}{5}x-10=30

<em>Add 10 to both sides</em>

<em />\frac{1}{5}x-10+10=30+10

\frac{1}{5}x=40

<em>Multiply both sides by 5</em>

<em />\frac{1}{5}x*\frac{5}{1}=40*\frac{5}{1}

x=200

Answer:  x=200
