Answer:

1. There is 1/9th chance that you'll get a multiple of 3 twice.

2. There is 2/3rds chance that you'll get a black ball.

Step-by-step explanation:

There is 1/3 chance that when you roll a dice once, you'll get a multiple of 3, so when you roll twice, there will be a (1/3)*(1/3) chance that you will get a multiple of 3 twice. (1/3)*(1/3)=1/9, so therefore, there is 1/9th chance that you will roll a multiple of 3 twice.

For every 1 white ball, there are 2 black balls. The ratio for black balls to white balls is 2:1. That means that there is 2/3rds chance that you will get a black ball.

Quadrilateral ABCD is inscribed in a circle. Find the measure of each angle of the quadrilateral.
Softa [21]

Angle A= 88°

Angle C= 92°

Angle D= 80°

Step-by-step explanation:

Step 1:

  From the basic property of Quadrilateral Angle A and Angle C are supplemental( Which means sum of Angle at A and Angle at C is equal to 180 degree)

Step 2:

From the given figure We could relate that

Angle at A = (X-2)°

Angle at C = (X+2)°

Angle at D = (X-10)°

  (X-2)° + ( X+2)° = 180°

On simplification

  X-2+X+2=180°

2X=180°

and X=180/2

    X = 90°

Angle at A= (90-2)° = 88°

Angle at C = (90+2)° = 92°

Angle at D= (90-10)° = 80°

Center: (10,-10)

This is the standard form equation \frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1

What is the ellipse?

The equation for an ellipse is typically written as x² a²  + y² b² = 1. x²  a² + y² b²  = 1. An ellipse with its origin at the center is defined by this equation. The ellipse is stretched further in both the horizontal and vertical directions if a > b, a > b, and if b > a, b > a, respectively.

The standard form of the equation of an ellipse with center (h, k)and major axis parallel to the x-axis is:

\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1

where,

a > b

the length of the major axis is 2a

the coordinates of the vertices are (h±a,k)

the length of the minor axis is 2b

the coordinates of the co-vertices are (h,k±b)

the coordinates of the foci are (h±c,k),

where c² = a² − b².

so,

\frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1

Hence, this is the standard form equation \frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1.
