There is a 0.9986 probability that a randomly selected 33​-year-old male lives through the year. A life insurance company charge
Helen [10]

Answer:

Expected Value = -$42 (loss of 42 dollars)

Step-by-step explanation:

Complete Question Below:

<em>"There is a 0.9986 probability that a randomly selected 33​-year-old male lives through the year. A life insurance company charges ​$182 for insuring that the male will live through the year. If the male does not survive the​ year, the policy pays out ​$110 comma 000 as a death benefit. If a 33-year-old male purchases the policy, what is his expected value?"</em>

<em />

We can say P(survival) = 0.9986 and thus P(not survival) = 1 - P(survival) = 1-0.9986 = 0.0014

Also,

In case 33 year old doesn't live, the payment would be 100,000 - 182 = $99,818

And

In case 33 year old lives, the payment is

-$182

We know, the <em>expected value is the sum of the product of each possibility with its probability.</em>

ExpectedValue=\Sigma x*p(x)=(99818)(0.0014)+(-182)(0.9986)=-42

This means a loss of $42 (or -$42)

HELP MATH LAST ONEE!! :D MARKING BRAINLISEST!
OlgaM077 [116]

Answer:

y = -11

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept → (0, b)

We have the slope m = 0 and the point (0, -11) → b = -11.

Substitute:

y = 0x - 11 = -11

It's a horizontal line.
