Suppose a life insurance company sells a $240,000 one year term life insurance policy to a 25-year old female for $210. The prob

skelet666 [1.2K]

Answer:

$112.08 every year.

Step-by-step explanation:

Let's suppose a game in which we bet a certain amount of money ''A'' to a certain result and the probability of that result is ''p''. If the prize that we get is ''P'' therefore the expected value of gain is :

$E=p(P-A)+(1-p)(-A)=pP-A$

Now,let's suppose that the female is ''betting on her death'' ⇒

P(she survives) = 0.999592

P(she doesn't survive) = 1 - 0.999592= $4.08(10^{-4})$

E(25-year old female) = $4.08(10^{-4}).(240000)-210=-112.08$

The negative sign of E is important.It means that every year the 25-year old female will lose $112.08.

Therefore, the expected value of this policy to the insurance company is $112.08 every year.

Answer:

Step-by-step explanation:

It starts going up by 6. Then it goes up by 2 more than six. 6, 8, 10. Going up 2 more than last time. 2018 would be 12 more, or 76, and 2019 would be 14 more, or 90.

Two friends go out to eat and order the same meal. They pay a 6% sales tax and a 20% tip on their meals. The total bill, includi

vova2212 [387]

Sales tax and tip will increase the price of an item.

The cost of each meal is: $10.89

Let the cost of both meals be x.

A 20% tip means that, the current price is:

$Price = x \times (1 + 20\%)$

A 6% sales tax on the meal means that, the current price is:

$Price = x \times (1 + 20\%) \times (1 + 6\%)$

So, we have:

$Price = x \times (1 + 0.20) \times (1 + 0.06)$

$Price = x \times (1.20) \times (1.06)$

$Price = x \times 1.272$

The amount paid is $27.72

So, the equation becomes

$27.72= x \times 1.272$

Make x the subject

$x = \frac{27.72}{1.272}$

$x = 21.78$

So, the cost of each meal is:

$Each= \frac{21.78}{2}$

$Each= 10.89$

Hence, the cost of each meal is: $10.89

determine the slope of the tangent to the curve at the point y=(3x)(sinx) at the point with x-coordinate pi/2

damaskus [11]

Answer:

Step-by-step explanation:

The slope of the tangent to a curve is the derivative of the curve. We need to find the derivative of the function and then evaluate the derivative at that given x value. The derivative is found using the product rule:

$y'=f(x)g'(x)+f'(x)g(x)$

Let's call 3x our f(x) and sin(x) our g(x). Filling in the formula for the derivative using the product rule looks like this:

$y'=3x(cosx)+3sinx$

That gives us the derivative, which is the slope formula that can be used at ANY x value anywhere on the curve to find the slope of the line tangent to the curve at that x value. If we want to find the slope of the tangent line to the curve at x = pi/2, we evaluate the slope formula at x = pi/2 (remember that y' is the same exact thing as the slope):

$y'(slope)=3(\frac{\pi}{2})(cos\frac{\pi}{2})+3(sin\frac{\pi}{2})$

From the unit circle (or experience, since you're in advaced math), we know that the cosine of pi/2 is 0 and that the sin of pi/2 = 1:

$y'(slope)=3(\frac{\pi}{2})(0)+3(1)$ simplifies to

y' (slope) = 3

That means that the slope of the line tangent to the curve at the point x = pi/2 is 3.
