Suppose a life insurance company sells a ​$190,000 ​one-year term life insurance policy to a 19​-year-old female for ​$290. The probability that the female survives the year is 0.999563. Compute and interpret the expected value of this policy to the insurance company.
Answer:
The expected value of this policy to the insurance company is $206.97
Step-by-step explanation:
Probability that Person doesn't die = 0.999563. Profit = Revenue - Cost; Profit = $290 - 0 = $290
Probability that Person dies = 1 - 0.999563 = 0.000437. Profit = Revenue - Cost; Profit = $290 - $190,000 = -$189,710
Expected Value E(X) = ∑xp(x)
E(X) = $290*(0.999563) + (-$189,710* 0.000437)
E(X) = $289.87327 - $82.90327
E(X) = $206.97
Thus, the expected value of this policy to the insurance company is $206.97

x3-216#answer
The factor of the cubic polynomial x³ + 216 will be (x + 6) and (x² – 6x + 36). Then the correct option is B.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The cubic polynomial is given below.
⇒ x³ + 216
Then the cubic polynomial is written as,
⇒ x³ + 6 × 6 × 6
⇒ x³ + 6³
We know that the formula of a³ + b³ is given as,
a³ + b³ = (a + b)(a² – ab + b²)
Compare the expression, we have a = x and b = 6. Then the expression will be
x³ + 6³ = (x + 6)(x² – 6x + 6²)
x³ + 6³ = (x + 6)(x² – 6x + 36)
The factor of the cubic polynomial x³ + 216 will be (x + 6) and (x² – 6x + 36).
Then the correct option is B.

The given figure is a regular hexagon with side length 12 and radius 10. Find its area.
Question 11 options:
A)
120
B)
96
C)
288
D)
576
Answer:
its C
Step-by-step explanation:
The area of a regular hexagon is 288 square units, which is option C.
What is a regular hexagon?A hexagon is a six-sided polygon. And a regular hexagon means, the hexagon's sides are equal.
And no interior angle has an angle measuring more than 120°.
As per the given information, we can create 6 equal size triangles.
For that find the length of the apothem,
As per Pythagoras' theorem,
Apothem = √(10)² - (6)² = √(64) = 8.
Now, the area of the regular hexagon can be described as,
S = 6 x 1/2 x 12 x 8
S = 288 square units.
Therefore, the area of the required hexagon is 288 square units.
