Using the permutation formula, as the order is important, it is found that there is a 0.000331 probability of selecting the balls in the desired order.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 4 balls will be taken from a set of 9, hence the total number of outcomes is:

[tex]P_{9,4} = \frac{9!}{5!} = 3024[/tex]

The desired outcome is only one, hence the probability is given by:

p = 1/3024 = 0.000331.

There is a 0.000331 probability of selecting the balls in the desired order.

Answer:

y int = -2

slope = 1

Step-by-step explanation:

x-y=2

-y=-x+2

y=x-2

y int = -2

slope = 1

Answer:

Slope = 1

Y-intercept = -2

Step-by-step explanation:

   First, we will put it into slope-intercept form.

x - y = 2

x = y + 2

y = x - 2

   This gives us the slope of one and the y-intercept being -2.

Answer:

Given that the area of the base is 440.4, all we would need to find out is the sum of all the areas of the triangles surrounding it.

Formula for area of a triangle:

A = BH x 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 simply means to divide the product of those two lengths(base and height) by 2.

Plug in what we know:-

A = BH x 1/2

A = 16(20) x 1/2

A = 320 x 1/2

A = 320/2

A = 160 mm is the area of one triangle, but we want to know the area of all 5 triangles, so;

160(5)

= 800 mm is the area of all the triangles.

Now add the base area to the area of all the triangles.

440.4 + 800

= 1,240.4 mm.

Therefore the surface area of this pyramid is 1,240.4 mm.

Answer:

1240.4 mm²

Step-by-step explanation:

The surface area of a pyramid = Area of the all sides + Area of base

Each side is a triangle.

With a regular pentagonal pyramid, the area of each triangle is

A = 1/2 x base x slant height

For the 5 triangles,

A = 5 x 1/2 x base x slant height = 1/2 x 5 x slant height

Substitute values,

A = 5 x 1/2 x 16mm x 20mm = 800 mm²

Area of base = 440.4 mm²

Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²

So D has the biggest volume.

Based on the information provided, the mean number of people in a class is 21 people.

To calculate the mean number, the general formula is the total of people in the class/ number of classes.

Then, let's find the total of people in classes by adding the number of people that are in class every day:

13+23+24+31+14 =  105 people in total

Number of classes: 5 classes or 5 days

The mean number of people in a class: Divide the total of people by the number of classes

105 / 5 = 21 people per class in average

Answer:

the slope of the line perpendicular to that line is 6/2

Step-by-step explanation:

Find the slope of the original equation by putting it into y=mx + b form

2x+6y=-4                  Given

2x-(2x)+6y=-4-(2x)   Subtract 2x from both sides

6y= -2x -4                Simplify

6y/6= -2x/6 -4/6      Divide both sides by 6

y= -2/6 x - 4/6          Simplify

*perpendicular slopes are opposite reciprocals*

-2/6 = slope

2/6 is the opposite of -2/6

6/2 is reciprocal of 2/6

Answer:

Acute and Scalene

Step-by-step explanation:

The measurments of the triangle are all almost equal and all the angles are less than 90 degrees, so all of them are acute angles. The scalene triangle has almost all equal sides.

The possible way to classify the triangle by side and angle measurements is,

⇒ Acute and scalene.

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°.

Since, All the angles are less than 90 degree.

Hence, It shows the Acute angle.

Here, Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm.

Clearly, All the sides of triangle are not same in length.

Thus, It shows scalene.

Thus, The possible way to classify the triangle by side and angle measurements is,

⇒ Acute and scalene.

Answer:

(π6x+21π)m²

Step-by-step explanation:

Solution,

For small circle

radius(r)=x+2

Area(A1)=πr²

Area(A1)=π×(x+2)²

Area(A1)=π×(x²+4x+4)

Area(A1)=πx²+π4x+4π

For big circle

radius(r)=x+5

Area(A2)=πr²

Area(A2)=π×(x+5)²

Area(A2)=π×(x²+10x+25)

Area(A2)=πx²+π10x+25π

Again,

Area of shaded part=A2-A1

Area of shaded part=πx²+π10x+25π-(πx²+π4x+4π)

Area of shaded part=πx²+π10x+25π-πx²-π4x-4π

Area of shaded part=π6x+21π

Answer:

(2,-3) and (49/29, -108/29)

Step-by-step explanation: Assuming this is an exam and time is limited, first you gotta sketch the circle for clarity. Using the standard circle equation

(x-a)^2 + (y-b)^2 = r^2

(x-1)^2 + (y+3)^2 =1

You can always expand to verify it gives x^2 + y^2 - 2x + 6y + 9=0

Now you know (a,b) which is also the center of the circle being= (1,-3) and the radius(r) = 1

Your first assumption here even without drawing the circle is that it has to be in the fourth quadrant meaning all values of x for any point of intersection on that circle has to be +ve. Looking at your answer choices only c with is (2,-3) and (49/29, -108/29) fulfills this hence it is your answer.

Also you have to realize point (2,-3) on the straight line has same y coordinates with center of this circle.

The quadratic equation y = -x^2 - 4x - 3 has a degree of 2

The vertex of the function is (-2,1)

The equation of the function is:

y = -x^2 - 4x - 3

Differentiate

y' = -2x - 4

Set to 0

-2x - 4 = 0

Solve for x

x = -2

Substitute -2 for x in y = -x^2 - 4x - 3

y = -(2)^2 - 4(-2) - 3

y = 1

The above means that the vertex of the function is (-2,1)
