Answer:

• let the number be x:

$• { \tt{ \dashrightarrow \: 2(x + 2)}}$

$• \dashrightarrow{ \tt{2x + 1}}$

$• \dashrightarrow{ \tt{ 2x + 1 = 21}} \\ \\ { \tt{2x = 20}} \\ \\ • \: { \boxed{ \tt{output : \: \: x = 10 \: \: }}}$

Let input be x

$\\ \bull\tt\dashrightarrow 2(x+2)-3=21$

$\\ \bull\tt\dashrightarrow 2(x+2)=21+3$

$\\ \bull\tt\dashrightarrow 2(x+2)=24$

$\\ \bull\tt\dashrightarrow x+2=\dfrac{24}{2}$

$\\ \bull\tt\dashrightarrow x+2=12$

$\\ \bull\tt\dashrightarrow x=12-2$

$\\ \bull\tt\dashrightarrow x=10$

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 tan if x?

Ne4ueva [31]

$\qquad\qquad\huge\underline{{\sf Answer}}$

The given triangle is a right triangle, with one of the acute angle measuring 45°

let's calculate x ~

$\qquad \tt \dashrightarrow \:x + 45 + 90 = 180$

$\qquad \tt \dashrightarrow \:x + 135 = 180$

$\qquad \tt \dashrightarrow \:x = 180 - 135$

$\qquad \tt \dashrightarrow \:x = 45 \degree$

So, tan x is :

$\qquad \tt \dashrightarrow \: \tan(x) = \tan(45 \degree)$

[ since x = 45° ]

$\qquad \tt \dashrightarrow \: \tan(x) = 1$
