Answer: 4.8%

Step-by-step explanation: the total amount of pens in the drawer is (10+12+3)  = 25

the amount of red pens in the drawer is 3

the probability of picking out a red pen from the drawer = 3/25

the amount of blue pens in the drawer is 10

the probability of picking out a red pen from the drawer = 10/25

the probability of picking out a red pen then a blue pen afterwards = (10/25 x 3/25) = 4.8%

The statement that is equivalent to |6x-3|=3 is: 6x-3=3 or 6x-3=-3

For the equation to be true, two scenarios need to be considered:

When the expression 6x-3 is positive and equals 3:

6x-3 = 3

When the expression 6x-3 is negative and equals -3:

6x-3 = -3

By solving these two equations, we can find the equivalent statement:

Solving 6x-3 = 3:

Adding 3 to both sides gives us:

6x = 6

Dividing both sides by 6:

x = 1

Solving 6x-3 = -3:

Adding 3 to both sides gives us:

6x = 0

Dividing both sides by 6:

x = 0

Therefore, the equivalent statement to |6x-3|=3 is:

6x-3=3 or 6x-3=-3, which can be further simplified to:

6x-3=3 or 6x-3=-3

Step-by-step explanation:

The support vector of the input dsolve('Dy = -3*y') is "dsolve(diff(y,t) == -3*y)".

A symbol is a mathematical object that represents a mathematical entity, such as a number, a variable, or a function. In mathematical software, symbols are used to represent variables, which can be used in mathematical expressions to perform computations.

In the past, character vectors or strings were used to represent symbols in certain mathematical software programs.

In the future release of this software, support for character vectors or strings will be removed. Instead, the program will require users to use the "syms" function to declare variables as symbols.

As an example of how this might be used in practice, consider the differential equation

=> "dy/dt = -3y".

In the past, this equation might have been entered into a mathematical software program using a character vector or string to represent the variable "y".

However, in the future release of this software, the user will need to use the "syms" function to declare "y" as a symbol. The equation would then be entered using the "diff" function, like this:

=> "dsolve(diff(y,t) == -3*y)".

Answer:

The area of the circle is \(\mathbf{6.25\pi}\)

Step-by-step explanation:

Area of a Circle

A circle of radius r has an area calculated by the following formula:

\(A=\pi r^2\)

The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.

A given circle has a diameter of 5 inches.

The radius of this circle is r = 5/2 = 2.5 inches.

Thus, the area is calculated below:

\(A=\pi 2.5^2 = 6.25\pi\)

The area of the circle is \(\mathbf{6.25\pi}\)

Answer:

Step-by-step explanation:

To check whether the given credit card number is valid or not, we need to apply the Luhn algorithm or the mod-10 algorithm. The Luhn algorithm works by adding up all the digits in the credit card number and checking if the sum is divisible by 10 or not. If it is, then the credit card number is considered valid, otherwise, it is invalid.

Let's apply the Luhn algorithm to the given credit card number:

Step 1: Starting from the rightmost digit, double every second digit

| 5 | 4 | 2 | 4 | 9 | 8 | 1 | 3 | 2 | 7 | 2 | 0 | 0 | 0 | 8 | 5 |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

| | 8 | | 8 | | 16| | 6 | | 14| | 0 | | 0 | | 10|

Step 2: If the doubled value is greater than 9, add the digits of the result

| 5 | 4 | 2 | 4 | 9 | 8 | 1 | 3 | 2 | 7 | 2 | 0 | 0 | 0 | 8 | 5 |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

| | 8 | | 8 | | 7 | | 6 | | 5 | | 0 | | 0 | | 1 |

Step 3: Add up all the digits in the credit card number, including the check digit

5 + 4 + 2 + 4 + 9 + 8 + 1 + 3 + 2 + 7 + 2 + 0 + 0 + 0 + 8 + 5 + 1 = 61

Step 4: If the sum is divisible by 10, then the credit card number is valid, otherwise, it is invalid.

61 is not divisible by 10, therefore the given credit card number is invalid.

Hence, it can be concluded that 5424 9813 2720 0085 is an invalid MASTERCARD credit card number.

Answer:

d. (600 - 81π) units ³

Step-by-step explanation:

Volume of the shaded portion = volume of triangular pyramid - volume of cone

= ⅓*A*h - ⅓πr²h

Where,

A = 15*10 = 150 units²

r = ½(9) = 4.5 units

h = 12

Plug in the values

Volume of the shaded portion = ⅓*150*12 - ⅓*π*4.5²*12

= (600 - 81π) units³

Check the picture below.

The coordinates of point Y are (9 , 12)

Step-by-step explanation:

* Lets explain how to solve the problem

- If point (a , b) divides a line whose end points are (c , d) and (e , f) at

ratio p : q from the point (c , d), then

 and

∵ Segment XY has one endpoint at X (0 , 0)

∵ Point (3 , 4) is 1/3 of the way from X to Y

∴ Point (3 , 4) divides the segment XY,  where the distance from X

 to the point (3 , 4) is 1 part and from point (3 , 4) to Y is 2 parts

∴ Point (3 , 4) divides segment XY to the ratio 1 : 2 from X

- Let point (a , b) is (3 , 4)

- Let point (c , d) is X (0 , 0)

- Let point (e , f) is Y

- Let p : q = 1 : 2

* Lets find e and f

∵

∴

∴

- Multiply both sides by 3

∴ 9 = e

∴ The x-coordinate of point Y is 9

∵

∴

∴

- Multiply both sides by 3

∴ 12 = f

∴ The y-coordinate of point Y is 12

* The coordinates of point Y are (9 , 12)

The area of the rhombus is equal to a rectangle with an area of 135ft² plus the area of one triangle with a base of 16ft and a height of 15ft.

A rhombus is defined as the type of a quadrilateral that is has four sides which has the same equal length.

The area of the given rhombus above can be gotten through the addition of the area of a rectangle and a triangle.

The area of the rectangle = length× width

where length = 15ft

width = 17-8 = 9ft

area of the rectangle = 15×9 = 135ft²

The area of the triangle = 1/2 base × height

base = 8+8 = 16ft

height = 15ft

The area of the triangle = 1/2 × 16 × 15 = 120ft²

Therefore the area of the rhombus = 135 + 120 = 255ft²

events B and C are not only dependent but also mutually exclusive. events B and C are mutually exclusive and dependent.

Based on the correct value of P(B AND C), the relationship between events B and C is as follows: We are given that P(B) = 0.6, P(C) = 0.4, and P(B AND C) = 0. If events B and C were independent, then we would have P(B|C) = P(B), which means that the occurrence of event C would not affect the probability of event B. However, since P(B AND C) = 0, we know that events B and C cannot occur simultaneously. Therefore, P(B|C) = 0. This means that if event C occurs, event B cannot occur. Therefore, events B and C are not only dependent but also mutually exclusive. In summary, events B and C are mutually exclusive and dependent.

Required equation represents

3 × 3/5 as a multiple of a unit fraction is 9 x 1/5.

To multiply a whole number by a fraction, you can convert the whole number to a fraction with a denominator of 1. So, 3 can be written as 3/1.

Now, to multiply 3/1 by 3/5, you can multiply the numerators (top numbers) together and the denominators (bottom numbers) together separately:

3/1 × 3/5 = (3 × 3) / (1 × 5)

Simplifying the numerator and denominator gives 9/5

To write this as a multiple of a unit fraction (a fraction with a numerator of 1), you need to rewrite 5 as a product of 1 and another number (in other words, find a denominator that is a multiple of 5):

5 = 1 × 5

Then, you can write 9/5 as:

9/5 = (9/1) × (1/5)

So, the equation that represents 3 × 3/5 as a multiple of a unit fraction is:

3 × 3/5 = 9 x 1/5

So, the correct option is D) 9 x 1/5.

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The given function is:

f(x) = -(x + 3) - 1

To find the interval over which the function is decreasing, we need to find the values of x where the function's derivative is negative.

The derivative of the function is:

f'(x) = -1

The derivative is a constant, which means the function has a constant slope of -1. Since the slope is negative, the function is decreasing over its entire domain.

Therefore, the interval over which the graph of f(x) = -(x + 3) - 1 is decreasing is (-∞, +∞).

There are \(1.18\times 10^24\) formula units in a 1.96 mol sample of NH4NO3.

What is Avagadaro's Number ?

Avogadro's number, denoted as N_A, is a fundamental physical constant that represents the number of particles (such as atoms, molecules, ions, or other particles) in one mole of a substance. One mole of a substance contains Avogadro's number of particles, which is approximately 6.022 x 10²³ particles.

The number of formula units in a sample of a compound can be calculated using Avogadro's number (6.022 x 10²³) and the molar mass of the compound.

The molar mass of NH4NO3 can be calculated as:

M(NH4NO3) = 14.01 + 4(1.01) + 14.01 + 3(16.00) = 80.04 g/mol

Therefore, the number of formula units in a 1.96 mol sample of NH4NO3 can be calculated as:

(1.96 mol NH4NO3) x (6.022 x 10²³ formula units/mol) = 1.18 x 10²⁴formula units

So, there are 1.18 x 10²⁴ formula units in a 1.96 mol sample of NH4NO3.

Answer:

The relationship between the number of faces, vertices, and edges of a three-dimensional object is described by Euler's formula, which states that for any polyhedron (a solid object bounded by flat faces), the number of faces (F), vertices (V), and edges (E) satisfy the equation F + V - E = 2. This formula is true for any convex polyhedron, such as a cube or a regular tetrahedron.

The formula is based on the fact that every face of a polyhedron is bounded by a closed loop of edges, and each vertex is where three or more edges meet. The total number of edges is the sum of the number of edges around each face, which is equal to twice the number of faces since each edge is shared by two faces, and the number of edges meeting at each vertex, which is equal to the degree of the vertex (the number of edges meeting at the vertex).

Therefore, by knowing the number of faces, vertices, and edges of a three-dimensional object, we can determine if it is a convex polyhedron and use Euler's formula to check if the numbers are consistent with a solid shape.
