Answer:

14/50 or 7/25 or 0.28 or 28%

Step-by-step explanation:

The spinner is spun 50 times.  (8+6+9+11+9+7=50)

It lands on 1 or 2 a total of 14 times. (8+6=14)

So the experimental probability is 14 out of 50.  There are several ways this can be represented.  It depends on what your teacher wants.  it could be as a fraction or a decimal or a percentage.

14/50 or 7/25 or 0.28 or 28%

Write an equation for the table 2 5 5.6 14 7 17.5 8 20
vova2212 [387]

The equation for the table is y = 2.5 x

Step-by-step explanation:

The table is:

  • x  →  2    :    5.6    :    7    :    8
  • y  →  5    :    14      :  17.5  :    20

Lets check if the table represents the linear relation by find the ratio between the change of each two consecutive y-coordinates and the change of their corresponding x-coordinates

∵ \frac{14-5}{5.6-2}=\frac{9}{3.6}=2.5

∵ \frac{17.5-14}{7-5.6}=\frac{3.5}{1.4}=2.5

∵ \frac{20-17.5}{8-7}=\frac{2.5}{1}=2.5

∴ The rate of change between each two points is constant

∴ The table represent a linear equation

The form of linear equation is y = m x + b, where m is the rate of change and b is value y when x = 0

∵ m = 2.5

- Substitute it in the form of the equation

∴ y = 2.5 x + b

- To find b substitute x and y by the coordinates of any point

  in the table above

∵ x = 2 and y = 5

∴ 5 = 2.5(2) + b

∴ 5 = 5 + b

- Subtract 5 from both sides

∴ 0 = b

∴ y = 2.5 x

The equation for the table is y = 2.5 x

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)
