Answer:

$18.89

Step-by-step explanation:

26.98x0.3= 8.094

26.98-8.094= 18.886

100% - 30% = 70%

The shirt is selling for 70% of the original price.

Multiply the original price by 70%

26.98 x 0.70 = 18.89

The sale price is $18.89

The equation 2x + 4k − 9 = kx − k + 1 is really a family of equations, because for each value of k, we get a different equation
Olegator [25]
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.

Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.

2(4) + 4k - 9 = (4)(4) - (4) + 1

Then 8 + 4k - 9 = 16 - 4 + 1, or       4k - 1 = 13.  Then 4k = 14, and k = 14/4, or (after reduction)  k = 7/2   

If the parameter k equals 7/2, then x = 4 is a solution to the given equation.

To check this out further, start with the proposed solution x = 5 and find k.

A life insurance company sells a $100,000 one year term life insurance policy to a 30-year old male for $475. The probability th
laila [671]

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:

E(X)=x\cdot P(X)

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:

E(\text{Insurance Company})=S\cdot P(S)+S'\cdot P(S')

                                     =(475\times 0.999172)+(-99525\times 0.000828)\\=474.6067-82.4067\\=392.20

Thus, the expected value for the insurance company is $392.20.

What is the value of i ^20+1?
matrenka [14]
Hey Mattchance666, 

    Lets solve this equation together,  

The question we are enquiring is : What is the value of i ^20+1?  

To solve this equation: we have to use the Power Reduction Rule. 

Where I^n=I{n mod 4}<span>

    </span>In this case: <span>I^20 = I^{5*4+0}=I^0</span>

1 + 1 = 2 

Hope this helps,
