Due to a negative value of P(X = x), it is found that the following is not a probability distribution.

---------------------

A sequence (x, P(X = x)) is a probability distribution if:

  • The sum of all values of P(X = x) equals 1.
  • There is no negative values of P(X = x).

In this problem, P(X = 2) is negative, thus, it is not a probability distribution.

9^3/9^9<br> What does this equation equal?
ololo11 [35]

I'm assuming the problem is nine to the third power divided by nine to the ninth power, so the answer would be 0.000001882. Fraction form would be 1/531441.

Sorry about the first answer, I read the problem wrong.

Is 7x-y=6 Independent
Stella [2.4K]
1. Slope = 7

2. x-intercept = 6/7 = 0.85714

3. y-intercept = 6/ - 1 = -6.00000

Rearrange:

Rearrange the equation by subtracting what is to the right if the equal sign from both sides of the equation:

7x-y- (6) = 0

Find the circumference of a circle with the diameter of 10 inches. Leave your answers in form of pi
MrRa [10]

Answer:

Circumference = 10π

Step-by-step explanation:

First identify the circumference formula as such:

2πr (where r ⇒ radius, π ⇒ pi)

Knowing 2 times the radius (2r) in the formula can be rewritten as the diameter, the formula itself can be rewritten as:

πd (where d ⇒ diameter, π ⇒ pi)

If we know the diameter = 10 inches, substitute in the circumference formula πd to get:

π * 10 inches = 10 * π inches = 10π inches

What is the value of the y coordinate of any point on the x axis?
Leona [35]

The value of the y coordinate of any point on the x axis is always 0.

<u><em>Explanation</em></u>

Suppose, the co ordinate of any point is (a,b) .

It means, the distance of the point from x-axis is 'b' and distance from y-axis is 'a'.

Now if the point lies on the x-axis, that means the distance of the point from x-axis will be 0. Thus, the value of 'b' will be 0.

So, the value of the y coordinate of any point on the x axis is always 0.
