There is a 0.9989 probability that a randomly selected 29-year-old male lives through the year. A life insurance company charges $197 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit.
Required:
a. From the perspective of the 29-year-old male, what are the monetary values corresponding to the two events of surviving the year and not surviving?
b. If the 29-year-old male purchases the policy, what is his expected value?
c. Can the insurance company expect to make a profit from many such policies? Why?
a. Surviving the year: $197; Not surviving the year: $100,000
b. Expected value: $306.78
c. The insurance company can expect to make $86.49 in profit per policy.
We have,
a.
From the perspective of the 29-year-old male:
Surviving the year:
The monetary value is the cost of the insurance premium, which is $197.
Not surviving the year:
The monetary value is the death benefit paid out by the policy, which is $100,000.
b.
To calculate the expected value for the 29-year-old male, multiply the probability of each event by its corresponding monetary value and sum them up:
Expected Value = (Probability of Surviving * Monetary Value of Surviving) + (Probability of Not Surviving * Monetary Value of Not Surviving)
= (0.9989 * $197) + (0.0011 * $100,000)
= $306.78
c.
Expected Premium Revenue
= Probability of Surviving * Premium Amount
= 0.9989 * $197
≈ $196.49
Expected Payout
= Probability of Not Surviving * Death Benefit
= 0.0011 * $100,000
≈ $110
Profitability
= Expected Premium Revenue - Expected Payout
= $196.49 - $110
≈ $86.49
Since the expected premium revenue exceeds the expected payout, the insurance company can expect to make a profit from many such policies.
In this scenario, the insurance company can expect to make $86.49 in profit per policy.
Therefore,
a. Surviving the year: $197; Not surviving the year: $100,000
b. Expected value: $306.78
c. The insurance company can expect to make $86.49 in profit per policy.

a. From the perspective of the 29-year-old male:
Surviving the year: The cost of insurance is $197.
Not surviving the year: The policy pays out a death benefit of $100,000.
b. The 29-year-old male's expected value is -$86.8013, indicating a potential loss.
c. Yes, the insurance company can expect to make a profit. The expected value is negative, meaning the company collects more in premiums than it pays out on average.
a. From the perspective of the 29-year-old male:
Surviving the year: The cost of insuring that the male will live through the year is $197.
Not surviving the year: The policy pays out a death benefit of $100,000.
b. To calculate the expected value for the 29-year-old male, we need to consider the probabilities of each event and their corresponding monetary values.
Expected Value = (Probability of surviving * Monetary value of surviving) + (Probability of not surviving * Monetary value of not surviving)
Probability of surviving = 0.9989
Monetary value of surviving = -$197 (since this represents the cost of insurance)
Probability of not surviving = 1 - Probability of surviving = 1 - 0.9989 = 0.0011
Monetary value of not surviving = $100,000
Expected Value = (0.9989 * -$197) + (0.0011 * $100,000)
Expected Value = -$196.8013 + $110
Expected Value = -$86.8013
Therefore, the expected value for the 29-year-old male is approximately -$86.8013.
c. The insurance company can expect to make a profit from many such policies because the expected value is negative (-$86.8013). The cost of insuring the male is $197, but the expected value is significantly less. This means that on average, the insurance company will collect more in premiums than it pays out in claims, resulting in a profit. The small probability of not surviving the year and the high payout of $100,000 contribute to the insurance company's ability to make a profit by spreading the risk among many policyholders.

how is a tangent different from a cord
Step-by-step explanation:
Chords: A chord of a circle is a segment that you draw from one point on the circle to another point on the circle. A chord always stays inside the circle. ... Tangent: A tangent to a circle is a line, ray, or segment that touches the outside of the circle in exactly one point. It never crosses into the circle.
Answer:
Chords: A chord of a circle is a segment that you draw from one point on the circle to another point on the circle.
Tangent: A tangent to a circle is a line, ray, or segment that touches the outside of the circle in exactly one point.
Step-by-step explanation:
A chord always stays inside the circle. The largest chord possible is the diameter — you can’t get any longer than that segment.
It never crosses into the circle. A tangent can’t be a chord, because a chord touches a circle in two points, crossing through the inside of the circle. Any radius drawn to a tangent is perpendicular to that tangent.

b.
l + w + d less-than 61
c.

Answer:
[tex]l + w + d \leq 61[/tex]
Step-by-step explanation:
Given
Sum of l, w and d be at most 61
Required
Write as inequality
First, we need to determine the sum of l, w and d
[tex]Sum = l + w + d[/tex]
Next, we determine the type of inequality.
At most 61 means less than or equal to 61
So, the expression becomes:
[tex]Sum \leq 61[/tex]
Substitute value for Sum

The diameter of a circle is 15 ft. Find its circumference in terms of \piπ.
Write the equation for the following graph (Hint: y= mx + b) Write the slope as a simplified fraction, not a decimal. Please Help
Answer:
y = (-5/2)x + 1
Step-by-step explanation:
We can see that the line intersects (0,1) and (2, -4). We use these points to find the slope: m = (-4-1)/(2-0) = -5/2. Also, the y-intercept is (0,1), so b = 1. Substituting these values into y=mx +b, we get y = (-5/2)x + 1.

On a blueprint, the length of a wall is 5 centimeters. If the actual length of the wall is 15 feet, what is the scale of the blueprint
Answer:
1 cm = 3 feet.
Step-by-step explanation:
Divide 15 by 5 to get 3; on the blueprint, every centimeter represents 3 feet.
The scale of scale factor of the blueprint is 1 cm = 3 feet.
What is a scale factor?The scale factor defines a variable in a ratio of two different measurements.
Sometimes drawings of large models are represented in a scale factor of a smaller unit.
Given, On a blueprint, the length of a wall is 5 centimeters and the actual length of the wall is 15 feet.
Therefore, The scale factor of the blueprint is,
= (5/15).
= 1/5.

Step-by-step explanation:
1.5% of 800 is 12.
You do 12 x 12 which is 144.
Next you do 800 - 144 which equals 656.

How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P\left(1 +\dfrac{R}{100}\right)^T[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P\left(1 +\dfrac{R}{100}\right)^T[/tex]
Given;
Purchase price (PV)= $800
Rate of decrease (r)= 1.5% per year
Number of periods (n)= 12 years
To calculate the value of the card after 12 years, we need to use the following formula of future value;
FV= PV / (1 + r)^n
FV= 800 / (1.015^12)
