Complete Question:

There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.

2 yellow, 3 pink, 5 blue    

Answer:

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 5[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 10[/tex]

When the first blue marble is selected, the probability is:

[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{5}{10}[/tex]

Since the first marble is not returned, we have the following marbles left

[tex]Blue = 4[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 9[/tex]

The probability of picking a second blue marble is:

[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{4}{9}[/tex]

So, the required probability is:

[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

============================================================

Explanation:

A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.

The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.

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

In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.

The third figure in the bottom row is not regular because one side is longer than the others.

Answer:

x = -17

y = -68

Step-by-step explanation:

x - y = 51

y/x = 4  so we can say that y = 4x

using substitution:

x - 4x = 51

-3x = 51

x = -17

find 'y':

-17 - y = 51

-y = 68

y = -68

check:

-17 - (-68) = 51

51 = 51

-68/-17 = 4

4 = 4

Answer:

No; a domain value has two range values.

Step-by-step explanation:

Because domain value is the x value and range value is the y value. If the x value repeats then it is not a function.

Answer: I think the answer is letter A . "No; a domain value has two range values".

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.... The range of the function is the set of all values that f takes.

Since  

x  =  − 1

produces  

y =  9

and  

y =  4 , the relation  

( − 1 , 9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 )

is not a function.

The relation is not a function.

what is domain value

The value of a domain name is the price any person/entity/organization has to pay in order to purchase a name for their website. The costs can range from a one-digit number to 6- or 7-digit numbers, depending on the valuation factors. Your domain could be the name of the next big start-up or brand.... The domain of a function f(x) is the set of all values for which the function is defined

The domain is the set of all the values of  

x

. The range is the set of all the values of  

y

.

Domain:

{ − 1 ,  0 ,  4 }

Range:

{ 9 ,  − 1 ,  4 }

Remove parentheses.

{ ( − 1 ,  9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 ) }

Find the inverse.

No inverse can be found

Answer: Slope of line = [tex]\frac{1.2}{2}[/tex]

Graph- see picture.

Step-by-step explanation:

Graphs are graphed using y=mx+b

Slope (m) is written as [tex]\frac{rise}{run}[/tex], and y coordinate is up and down, x is left & right.

The y coordinate adds 1.2 every time, so the rise is 1.2.

The x coordinate adds 2 every time, so the run is 2.

The y intercept (b) simply means where the line intercepts the y axis.

It is given that the y intercept is 0.

So, the graphing equation: y= [tex]\frac{1.2}{2}[/tex]x

We don't need to put the y intercept because it is 0!

The graph is attached!

Step-by-step explanation:

y is the geometric mean of the segment lengths.

  y = √(4·1)

  y = 2

You can also get there by considering the similarity of the triangles:

  short side / long side = y/4 = 1/y

  y^2 = 4 . . . . . . . multiply by 4y\

  y = √4 = 2 . . . . take the square root

Answer:

x/121 + y/9 = 1

Step-by-step explanation:

The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.

Becasue the major axis is horizontal, this ellipse is wider than it is tall.

The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.

The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.

The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b

(x-0)²/11² + (y-0)²/3² = 1

*** x/121 + y/9 = 1

The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b

If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.

If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

The 'brainly ellipse' is form this particular problem.
