I neeed helpppp can someone help me?
SVETLANKA909090 [29]

Answer:

-8/5

Step-by-step explanation:

The thing that makes lines different from other kinds of curves is their <em>constant rate of change</em>. We call this rate of change <em>slope</em>, and you usually see it represented with the letter <em>m</em>. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.

We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate <em>increases </em>by 5, while our y-coordinate <em>decreases </em>by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as

m = -8/5

An insurance company is setting out its policy for the next year. The chance that a customer (on average) survives another year
Doss [256]

Answer:

The expected loss is  E  =  $6980

Step-by-step explanation:

From the question we are told that

     The  chance that a customer  survives another year is p =0.96

     The rate at which the policy is sold is   r =  $85 per month

      The rate at which the policy is sold per year is   R =  $85 * 12 per year

                                                                                          = $1020 per year

     The amount paid the the beneficiaries is  A =$200,000

The expected value of profit/loss for this company is mathematically represented as

            E  =  R -[ (1-p)*A]

substituting values

            E  =  1020 -[ (1-0.96)*200000]

             E  =  1020 -8000

             E  =  - $6980

The negative sign shows that it is a loss
