According to the tables used by insurance companies, a 47-year old woman has a 0.179% chance of passing away during the coming y
allsm [11]

The expected value for the person buying the insurance is -25.

<h3>How the expected value is calculated?</h3>

The expected value is the average gain or loss of an event if the event is repeated a number of times.

Expected value = ∑xP(x)

<h3>Calculation:</h3>

It is given that,

The probability of a 47-year-old woman passing away during the coming year is 0.179% = 0.00179

The death benefit = $100,000 - $204 = $99,796

The loss from living = -204

Then the expected value = 99796(0.00179) + (-204)(0.99821) = -25

Therefore, the expected value for the person buying the insurance is -25.

(SAT Prep) If the lengths of two sides of a triangle are 5 and 9 which would be length of the third side?
julia-pushkina [17]

The length of third side of triangle is 4 or 14.

According to the statement

we have given that the two sides of the triangle which are 5 and 9 and we have to find the length of the third side of triangle.

So, For this purpose, we know that the

If we had a triangle with sides a, b and c, then we can say

b-a < c < b+a

where b is larger than 'a'. This is the triangle inequality theorem

In this case, a = 5 and b = 9 so,

b-a < c < b+a

9-5 < c < 9+5

4 < c < 14

Telling us that c is some number between 4 and 14, not including either endpoint. If c is a whole number, then c could be any value from this set.

And

We see that the numbers 4 and 14 are in this set. The values 2 and 7 are not in the set.

So, The length of third side of triangle is 4 or 14.

Please Help Me. The table shows a proportional relationship.
matrenka [14]
To find the box answer, you can divide y by x:

\frac{y}{x}

You can check every pair, bit I'm going to show you the first 2 as an example:

\frac{ - 6}{ - 4}  =  \frac{3}{2}  \\   \\ \frac{ - 3}{ - 2}  =  \frac{3}{2}

So 3/2 is the answer!
