There are 2 red marble, 4 green marbles and 4 blue marbles. What is the probability or randomly selecting a green not replacing it, then selecting a blue ??

Answer:

x = 45

Step-by-step explanation:

x = (360 - 135 * 2) / 2

x = (360 - 270) / 2

x = 90 / 2

x = 45

Then add!

Given:

The center of the circle = (-1,0)

Point on the circle = (2,-4).

To find:

The equation of the circle.

Solution:

Distance between two points is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between the center (-1,0) and the point on the circle (2,-4) is the radius of the circle.

[tex]r=\sqrt{(2-(-1))^2+(-4-0)^2}[/tex]

[tex]r=\sqrt{(2+1)^2+(-4)^2}[/tex]

[tex]r=\sqrt{(3)^2+(-4)^2}[/tex]

On further simplification, we get

[tex]r=\sqrt{9+16}[/tex]

[tex]r=\sqrt{25}[/tex]

[tex]r=5[/tex]

Now, the equation of the circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, (h,k) is the center and r is the radius of the circle.

The radius of the circle is 5 and the center is at (-1,0), so the equation of the circle is

[tex](x-(-1))^2+(y-0)^2=5^2[/tex]

[tex](x+1)^2+y^2=25[/tex]

Therefore, the first option is correct, i.e., [tex](x+1)^2+y^2=25[/tex].

can you tell me the grade so I can help you please

Answer:

x = 9.15

Step-by-step explanation:

6.1/x = 2/3

multiply both sides by x and 3

3(6.1) = 2x

2x = 18.3

divide both sides by 2

x = 9.15

Answer:

x=9.15

Step-by-step explanation:

6.1 x 3= X times 2

18.3 = X times 2

X times 2 =18.3

(X times 2) divided by 2 = 18.3/2

which gives the answer

x=9.15

Answer:

2

Step-by-step explanation:

since they are similar

they will be divided by 9 for example

we have 54 on the left but if you divide it by 9 we get 6 which is on the right

then we have 27 on the left if you divide by 9 we get 3 which is on the right

so then we have 18 and a missing number

so we divide 18/9 and get 2

(f  o g)(x) = f (g (x)) = f (x - 4) = (x - 4)²

→   (f  o g)(-1) = (-1 - 4)² = (-5)² = 25

Answer:

The answer is 36

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

92÷18

Applying the fractions formula for division,

=9×82×1

=722

Simplifying 72/2, the answer is

=36

Given the coordinates M (-6, -4) and T (9, 16)

If the coordinates are divided in the ratio 2:3 then a = 2, b = 3

The y coordinate of the point Q will be expressed as;

Y = ay1+by2/a+b

From the coordinates, y1 = -4 y2 = 16

Y = 2(-4)+3(16)/2+3

Y = -8+48/5

Y = 40/5

Y = 8

Hence the y-coordinate of the point Q is 8

Answer:

(-5,3)

Step-by-step explanation:

The point (5,7) translated down 4 units gets to the point (5,3). If you reflect it over the y-axis, the x-coordinate becomes negative, and the y-coordinate stays the same. This gets you the point (-5,3)

Hope it helps and is correct!

Answer:

Step-by-step explanation:

(3,-5/2)

The midpoint of the line segment with these endpoints (-3, -8) and (9, 3) will be (0, 0.5).

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The endpoints of the line segment are given below.

(-3, -8) and (9, 3)

The midpoint of the line segment is calculated as,

(x, y) = [(-3 + 3) / 2, (-8 + 9)/ 2]

(x, y) = (0/2, 1/2)

(x, y) = (0, 0.5)

The midpoint of the line fragment with these endpoints (- 3, - 8) and (9, 3) will be (0, 0.5).

More about the mid-point of the line segment link is given below.
