a bag contains 40 pieces of candy, of which 36 are mint and 4 strawberry flavor. if the pieces of candy are distributed in a random manner to four children so that each child receives 10 pieces, what is the probability that all four strawberry pieces will be received by the same child?

Answer:

(-4,-7)

Step-by-step explanation:

Multiply both sides of the first equation by-5 or 2 (I'll use 5) and both sides of the second equation by - 2 or 3 (I'll use -2).

3x - 2y = 2

5(3x-2y)= 5(2)

-15x - 10y = 10

2x - 5y = 27

-2(2x - 5y) = -2(27)

-4x + 10y = -54

Now you see that the absolute values of the y-values of the 2 equations match up . They are still the same equations but scaled up.

-15x + 10y = 10

-4x - 10y = -54

Add to eliminate y.

-11x = 44

Divide both sides by -11.

[tex]\frac{-11x}{-11} = \frac{44}{-11}[/tex]

x = -4

Plug back in to either equation to solve. I'll use the first equation.

3x - 2y = 2

x = - 4

3(-4) - 2y = 2

-12 - 2y = 2

Add 12 on both sides.

-12 + 12 - 2y = 2 + 12

- 2y = 14

Divide -2y on both sides.

[tex]\frac{-2y}{-2} = \frac{14}{-2}[/tex]

y = -7

(-4,-7)

y=-3/4x-9/2 is the equation of a line that goes through both transformed points.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

we must translate the given point (x,y) into the translation given. We begin with the 90 degree clockwise rotation such that

90 degree clockwise rotation = (x, y) => (y, -x)

we translate the coordinate (y, -x)

2 units to the right such that

(y-4, -x - 2)

So the coordinate of points changed (1,2) and (-4,6) from (-2, -3) and (2, -6)

m=-6-(-3)/2-(-2)

m=-3/4

Now let us find the y intercept.

-3=-3/4(-2)+b

-3=3/2+b

-3-3/2=b

-9/2=b

Hence, y=-3/4x-9/2 is the equation of a line that goes through both transformed points.

The Total Square Footage of the House is 780 sq. ft.

What is Area?

The quantity area indicates the extent of a region on a planar or curved surface. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas area of a plane region or plane area refers to the area of a form or planar lamina.

Solution:

Area of Living Room = 20*15 = 300 sq. ft.

Area of Kitchen = 12*10 = 120 sq. ft.

Area of Bedroom 1 = 12*12 = 144 sq. ft.

Area of Bedroom 2 = 12*10 = 120 sq. ft.

Area of Bathroom = 8*12 = 96 sq. ft.

Answer:

The last graph that is a straight line represents y as a function of x

Step-by-step explanation:

In order for a graph to be considered a function, it can't intercept the same value twice. To test this, use the vertical line test to see if the graph hits the line twice. If it does, then it is not a function. But if the line hits the graph only once, then it is a function.

If the radius of the base of a cone is decreasing at rate of 2 cm/minute and the height is kept constant at 9 cm, the rate of change of the volume at radius 13 cm is 489.4 cm³/minute

To calculate the rate of change, we need to take the derivative of the variables with respect to time.

The volume of a cone is given by:

V = 1/3 . πr²h

Where:

r = radius of the base

h = height

Since the height of the cone is held constant, then the derivative with respect to time is:

dV/dt = 1/3 h. 2πr dr/dt

Parameters given:

dr/dt = 2 cm/minute

h = 9 cm

r = 13 cm

Hence,

dV/dt = 1/3 x 9 x 2π x 13 x 2

dV/dt = 489.4 cm³/minute

Hence, at radius 13 cm, the rate of change of the volume is 489.4 cm³/minute

It looks like there was typos in your question, most probably your question was:

The divergence theorem, commonly known as Gauss' theorem or Ostrogradsky's theorem, is a theorem that connects the flow of a vector field across a closed surface to the field's divergence in the volume enclosed.

In more detail, the divergence theorem states that the surface integral of a vector field across a closed surface, sometimes referred to as the "flux" through the surface, is equal to the volume integral of the divergence over the region inside the surface.

Therefore the flux is 16π .

The rate the level in the tank falling when the height of the syrup level is 3 feet is 8/π feet per minute. The result is obtained by using the rate of change concept.

A conical tank containing syrup is draining.

Find the rate of syrup level falling (dh/dt) when h = 3 ft!

See the picture in the attachment!

By the similar triangles, we get

r/h = 2/6

r/h = 1/3

r = 1/3 h

Find the volume of the syrup left at a certain height.

V = 1/3 πr²h

V = 1/3 π(1/3 h)²h

V = 1/3 π(1/9) h² h

V = 1/27 πh³

The rate of syrup level falling is

dV/dt = dV/dh . dh/dt

dV/dt = d/dt [1/27 πh³] . dh/dt

dV/dt = 1/27 π 3h² dh/dt

8 = 1/27 π 3(3)² dh/dt

8 =  π dh/dt

dh/dt = 8/π ft/min

The constant of proportionality in this proportional relationship is (D) 5/12.

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality.

Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.

So, the constant of proportionality formula:

y = kx ⇒ k = y/x

Now, calculate as follows:

(A)

k  = y/x

k = 5/6 / 2

k = 5/6 * 1/5

k = 5/12

(B)

k  = y/x

k = 5/3 / 4

k = 5/3 * 1/4

The easiest way to solve 4 linear equations is to use the substitution method. This involves substituting the values of one equation into the other equations until you are left with a single equation that can be solved for the remaining variable.

if you have the following four linear equations:

A + B = 10

A - B = 2

A + C = 12

A - C = 3

You can substitute A = 10 - B into the third and fourth equations to get:

10 - B + C = 12

10 - B - C = 3

Then you can add the two equations together and solve for C:

2B + 2C = 15

2C = 15 - 2B

C = (15 - 2B) / 2

Once you have C, you can substitute it into one of the other equations to solve for B:

A + B = 10

A = 10 - C

B = 10 - (15 - 2B) / 2

B = 5 - (15 - 2B) / 2
