Step-by-step explanation:

<em>Hello</em><em>!</em><em>!</em><em>!</em>

<em>Given</em><em>, </em><em> </em><em>VXW</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>Right angled triangle</em><em> </em><em>where</em><em> </em><em>WV</em><em> </em><em>=</em><em>4</em><em> </em><em>and</em><em> </em><em>XV</em><em> </em><em>=</em><em>5</em><em>.</em>

<em>now</em><em>,</em><em> </em><em>b</em><em>y</em><em> </em><em>taking</em><em> </em><em>reference angle</em><em> </em><em>as angle </em><em>W</em><em>,</em><em> </em><em>and</em><em> </em><em>using</em><em> </em><em>tangent</em><em> </em><em>we</em><em> </em><em>get</em><em>;</em>

<em>p</em><em>=</em><em>5</em>

<em>b</em><em>=</em><em>4</em>

<em>again</em><em>, </em>

<em>tan</em><em> </em><em>thita</em><em> </em><em>=</em><em>p</em><em>/</em><em>b</em>

<em>tan</em><em> </em><em>thita</em><em> </em><em>=</em><em> </em><em>5</em><em>/</em><em>4</em>

<em>so</em><em>,</em><em> </em><em>tan</em><em> </em><em>thita</em><em> </em><em>=</em><em>1</em><em>.</em><em>2</em><em>5</em><em>.</em>

<em>now</em><em>,</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>angle</em><em> </em><em>W</em><em>,</em><em> </em><em>we</em><em> </em><em>should</em><em> </em><em>d</em><em>o</em><em> </em><em>tan</em><em> </em><em>thita</em><em> </em><em>inverse</em><em>;</em>

<em>or</em><em>,</em><em> </em><em>(</em><em>tan</em><em> </em><em>thita</em><em>)</em><em>-1</em><em>=</em><em> </em><em>tan</em><em> </em><em>thita</em><em>-1</em><em>(</em><em>1</em><em>.</em><em>2</em><em>5</em><em>)</em>

<em>or</em><em>,</em><em> </em><em>(</em><em>tan</em><em> </em><em>thita</em><em>)</em><em> </em><em>-1</em><em> </em><em>=</em><em>5</em><em>1</em><em>.</em><em>3</em><em>4</em><em>0</em><em>1</em><em>°</em><em>.</em>

<em>Now</em><em>,</em><em> </em><em>by</em><em> </em><em>rounding</em><em> </em><em>off</em><em> </em><em>we</em><em> </em><em>get</em><em>,</em>

<em>tan</em><em> </em><em>thita</em><em> </em><em>(</em><em>angle</em><em> </em><em>W</em><em> </em><em>)</em><em>=</em><em> </em><em>5</em><em>1</em><em>°</em><em>.</em>

Avicenna, a major insurance company, offers five-year life insurance policies to 65-year-olds. If the holder of one of these pol
ki77a [65]

Answer:

Avicenna can expect to lose money from offering these policies. In the long run, they should expect to lose ___33__ dollars on each policy sold

Step-by-step explanation:

Given :

The amount the company Avicenna must pay to the shareholder if the person die before 70 years = $ 26,500

The value of each policy = $497

It is given that there is a 2% chance that people will die before 70 years and 98% chance that people will live till the age 70.

The expected policy to be sold= policy nominal + chances of death

                                      = 497 + [98% (no pay) + 2% (pay)]

                                     = 497 + [98%(0) + 2%(-26500)]

(The negative sign shows that money goes out of the company)

                                   = 497 - 2% (26500)

                                  = 497 - 530

                                  =33

Therefore the company loses 33 dollar on each policy sold in the long run.
