The solution to the system of linear equations is where the two lines intersect.

Look for the point where the two lines intersect. The x-value is 2 1/2, and the y-value is -4.

The answer is C.

Answer:

C). (2 *1/2, -4)

Step-by-step explanation:

The solution to the system of linear equation is where the the x axis intercept the y axis..

So if we use Tracing method, we'll discover that where both axes meet is at

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.

Which expression represents the polynomial −2x3−4x2+2x4+3x+4 rewritten in standard form?

Alja [10]

Answer:

10 x^4 - 8x^5

Explanation:

To write a polynomial in standard form, simplify and then arrange the terms in descending order. Ex. ax^2+ax+c

Then you would simplify

−2 x−5(x^2x^2)−2x4(x^2x^3)

Simplify each term

= 10 x^4 - 8x^5
