After 2 hours, the Serenity and Mystic sailboats will be 68 miles apart. To determine how far apart the Serenity and Mystic sailboats will be after 2 hours, we need to calculate the total distance each boat will travel in that time.

The distance that the Serenity travels is:

distance = rate x time = 13 mph x 2 hours = 26 miles

The distance that the Mystic travels is:

Distance = rate x time = 21 mph x 2 hours = 42 miles

To use this formula, you need to know the rate at which the object is traveling and the time it has been traveling.

Simply multiply the rate by the time to calculate the distance traveled.

Since they are traveling in opposite directions, we can add these distances to find the total distance between them:

total distance = distance traveled by Serenity + distance traveled by Mystic

total distance = 26 miles + 42 miles

total distance = 68 miles

The answer is 4 times the cube of the first number minus the sum of the second number and two times the third number. That is the result of the calculation is -6.

To calculate this, first, we multiply the first number by itself twice to get the cube of the first number. Then, we subtract the sum of the second and third numbers multiplied by two from the cube of the first number. This result is our answer.

For example, let's say we have the numbers 2, 3, and 4. We first calculate the cube of 2, which is 8. Then, we subtract the sum of 3 and 4 multiplied by two, which is 14. So, the final answer is 8 - 14 = -6.

We can also show the stepwise calculation as follows:

= 2³ - (3 + 2 × 4)

= 8 - 14

= -6

The mean absolute deviation of the set of numbers 2, 3, 3, 6, and 1 is 1.2.

What is the mean absolute deviation?

Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. Similar to standard deviation, MAD is a parameter or statistic that measures the spread, or variation, in your data.

To find the mean absolute deviation of a set of numbers, we first need to find the mean of the set. The mean is the sum of the numbers divided by the total number of numbers. For the set of numbers 2, 3, 3, 6, 1, the mean is:

mean = (2 + 3 + 3 + 6 + 1) / 5

= 15 / 5

= 3

Next, we need to find the absolute deviation of each number in the set from the mean. The absolute deviation is the absolute value of the difference between the number and the mean. For each number in the set, we calculate the absolute deviation as follows:

|2 - 3| = 1

|3 - 3| = 0

|3 - 3| = 0

|6 - 3| = 3

|1 - 3| = 2

To find the mean absolute deviation, we take the average of the absolute deviations. We add up the absolute deviations and divide by the total number of numbers in the set:

mean absolute deviation = (1 + 0 + 0 + 3 + 2) / 5

= 6 / 5

= 1.2

Therefore, the mean absolute deviation of the set of numbers 2, 3, 3, 6, and 1 is 1.2.

Since the graph is constant, the function is not changing within any interval. Therefore, there are no intervals where the function is changing.

In mathematics, a graph is a visual representation of a set of objects and the relationships between them. Graphs are widely used in many areas, including mathematics, computer science, engineering, social sciences, and more.

A graph consists of two main components: vertices (also known as nodes) and edges. The vertices represent the objects, and the edges represent the connections or relationships between them. The edges can be directed or undirected, meaning they can be one-way or two-way relationships.

There are many types of graphs, including:

Undirected graphs: Graphs in which edges have no direction.

Directed graphs: Graphs in which edges have a direction, often represented by arrows.

Weighted graphs: Graphs in which edges have weights or values, representing some kind of numerical data.

Bipartite graphs: Graphs in which the vertices can be divided into two distinct sets, with edges only connecting vertices in different sets.

Complete graphs: Graphs in which every vertex is connected to every other vertex by an edge.

Graphs are used to model and analyze various kinds of data, such as social networks, transportation systems, financial transactions, and more. They are also used in algorithms and data structures, such as shortest path algorithms and tree data structures. In addition, graphs are often visualized using software tools to help people better understand complex relationships and patterns in data.

The probability that he will make both free throws is 0.84.

What exactly is the meaning of probability?

Probability expresses the possibility of an event. This branch of mathematics studies the occurrence of a random event. The value ranges between 0 and 1. Probability is used in mathematics to anticipate the possibility of events occurring.

Probability refers to the likelihood of something occurring. This fundamental premise of probability theory is used by the probability distribution. We must first know the entire number of possibilities before we can assess the possibility of an event occurring.

P(E) is the probability of an event occurring divided by the total number of outcomes.

Now,

Given that player makes 92% of freethrows

that means p(making free throws)=92/100

=23/25

so making two free throws probability will be =23*23/25*25

To find the original price, you will multiply the discount price by 25%, or 0.25.

0.25 * 17.25 = 4.3125 or 4.31

Now you will ad that to the discount price to find the original price:

4.31 + 17.25 = 21.56

The original price was $21.56.

Step-by-step explanation:

Hope it helps! =D

Answer:

$21.56

Step-by-step explanation:

A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

To solve this, we can multiply the price by 1.25.

We multiply by 1.25 because in order to solve for the original price of an object that was 25% off, we have to add that 25% back. The reason we don't multiply by 0.25 is because if we were to do so, the price would be getting smaller, not larger.

Therefore, the original price is $21.56

Step-by-step explanation:

I took the test one time before .

Required probability P(A)= 0.46. The problem here is a Joint Probability Distribution exercise. See the answers and explanation below.

Joint Probability Distribution can be simply described as the likelihood of two events (variables) occurring at the same time. These two events are commonly referred to as event A and event B, and their formal names are: p (A and B).

here, we have,

What is the solution to the questions?

A - The likelihood that each line has exactly one customer: The probability relates to the associated row and column.

X₁ = 1  and X₂ = 1

P (X₁ = 1, X₂ =1) = 0.15

B - The sum of the diagonal elements of the joint pmf indicates the likelihood that the amount of clients in both lines is the same:

P(X₁ = X₂) =) p(0,0) + p (1,1) + p(2, 2) + p(3,3

= 0.08 + 0.15 + 0.10 + 0.07

= 0.4

Hence,

C - Let A represent the situation in which there are at least two more clients than the other line: The following are examples of variable combinations:

X₂ =0 ;   X₁ = 2,3, 4

X₂ =1  ;   X₁ = 3, 4

X₂ =2 ;   X₁ = 0, 4

X₂ =3 ;   X₁ = 0, 1

The probability is thus computed as follows:

P (A) = p(1, 3) + p (2,2) + p(2, 3) + p(3,1) + p(3,2) + p(3,3) + p(4,0) + p(4,1) + p(4,2) + p(4,3)

= 0.04 + 0.10 +0.06 + 0.03 + 0.04+ 0.07 + 0.00 + 0.01 + 0.05 + 0.06

Answer:

W = 8cm

L = 19cm

Step-by-step explanation:

The first step to solving these problems is always writing the information that is given into 2 equations.

Piece of info #1: Length is 5cm less than 3 times the width

Piece of info #2: Perimeter (of the rectangle, which has 4 sides) is 54cm

Turing these into equations...

Equation 1) L = 3*W - 5

Equation 2a) L+L+W+W = 54

Let's simplify that second equation:

Equation 2b) 2L+2W = 54

Now, we just solve the system of two equations by substitution. Take the known value of L from equation 1 and substitute it in for the value of L in equation 2b:

2*(3*W-5)+2W = 54

Now we solve for W:

6W - 10 + 2W = 54

8W - 10 = 54

8W = 64

W = 64/8

W = 8 cm

Now that we know W, we can substitute its value into either equation 1 or equation 2 to find L. Here, I'll randomly choose equation 1.

Equation 1) L = 3*W - 5

L = 3*8 - 5

L = 24-5

L = 19 cm

Plug in values for x:

5(2) + 5y = 18

10 + 5y = 18

Solve for y.

Answer:

The missing coordinate is 1.6.

Step-by-step explanation:

A coordinate is two points, x value and y value, on a graph. Ex: 1, 4. 1 is on the x axis, and 4 is on the y axis. In some Math problems, the point in the x value will be replaced with x.

5x + 5y = 18

5(2) + 5y = 18

10 + 5y = 18

10 - 10 + 5y = 18 - 10

5y = 8

5y/5 = 8/5

y = 1.6

To check this, we need to input 2 and 1.6 into the original problem.

5(2) + 5(1.6) = 18

10 + 5(1.6) = 18

5x - 9x = -55 - 21

-4x = -76

X = 19
