Answer:
The expected value for the insurance company is $392.20.
Step-by-step explanation:
The expected value of a random variable, <em>X</em> is:
It is provided that a life insurance company sells a $100,000 one year term life insurance policy to a 30-year old male for $475.
The probability that the male survives the year is, P(S) = 0.999172.
Then the probability that the male does not survives the year is:
P (S') = 1 - P (S)
= 1 - 0.999172
P (S') = 0.000828
The amount the company owes the male if he survives is, S = $475.
The amount the company owes the male if he does not survives is,
S' = $475 - $100,000 = -$99525.
Compute the expected value for the insurance company as follows:
Thus, the expected value for the insurance company is $392.20.
Answer:
The ratio representing the tangent of ∠K is 40 : 9.
Step-by-step explanation:
Consider the right-angles triangle KLM below.
The angle M is 90°.
KM = perpendicular (<em>p</em>) = 40
ML = base (<em>b</em>) = 9
LK = hypotenuse (<em>h</em>) = 41
The tangent of an angle is the ratio of the perpendicular length to the length of the base.
Compute the tangent of ∠K as follows:
Thus, the ratio representing the tangent of ∠K is 40 : 9.
