How many points do you need to know to draw the graph of a direct proportionality? which are?

A measurable part of a line that consists of two points, called endpoints, and all of the points between them are called Line sigments.

Geometry is a branch of mathematics that deals with how objects can be expressed as relationships of points, lines, planes, surfaces, and dimensions. When we draw lines in geometry, we use an arrow at each end to show that it expands infinitely. A line is a path between two points that can be measured. Since line segments have a defined length, they can form the sides of any polygon. The figure below shows the line AB, where the length of the line AB is related to the distance between its endpoints, A and B. The symbol for the line is named after its two endpoints, e.g.

\( \bar{AB}\)

Answer:

3x(2x - 3)

Step-by-step explanation:

Given

y = 6x² - 9x ← factor out 3x from each term

  = 3x(2x - 3)

The constant of integration C1 was found by using the initial condition X'(0) = (-3/8), and the constant C2 was found by using the initial condition X(0) = (0) - (5).

To solve the given initial-value problem, we start by rearranging the equation:
3 11 16 × -(: * *:)* X' = 1 1 3
-(: * *:)* X' = (1/16)  (1/11)  (1/3)
Integrating both sides with respect to t:
-(: * *:)* X = (1/16) t + C1, where C1 is the constant of integration.
Multiplying both sides by the inverse of the matrix -(: * *:) gives:
X = (-1/8) t + C1/8 + C2, where C2 is another constant of integration.
To find the values of C1 and C2, we use the initial condition X(0) = (0) - (5):
X(0) = (-1/8) (0) + C1/8 + C2 = -5
C1/8 + C2 = -5
Since X'(t) = (-3/8), we have X'(0) = (-3/8). Using the equation X'(t) = (-3/8) and the initial condition X(0) = (0) - (5), we can solve for C1:
X'(t) = (-1/8) => (-3/8) = (-1/8) + C1/8 => C1 = -2
Substituting C1 = -2 into C1/8 + C2 = -5 gives:
(-2)/8 + C2 = -5 => C2 = -39/8
Therefore, the solution to the initial-value problem is:
X = (-1/8) t - 1/4 - (39/8)

The solution to the given initial-value problem is X = (-1/8) t - 1/4 - (39/8). The constant of integration C1 was found by using the initial condition X'(0) = (-3/8), and the constant C2 was found by using the initial condition X(0) = (0) - (5).

Answer: 67

explanation:

47 x 13 = 611    -- so this is how many tickets he has total

611 / 9 = 67.9

So he can get 67 prizes.

a way you can check if this is right is by multiplying 67 by 9 and you see that is 603, and he has 611 tickets so he will even have a few tickets left over. but he can not get 68 prizes because if you see what 68 x 9 is, it is 612 which is one ticket more than what he has so he cant get it. So the max he can get is 67

Answer:

67

Step-by-step explanation:

We know that, in total, he made 47 baskets, and each basket is 13 tickets.

So in total, he made 611 tickets:

47·13

=611

Next, he wanted to get [a] prize(s), but each prize costs 9 tickets, we divide the total number of tickets he has by the prize cost.

611/9

=67.88...

You obviously can't get 0.88 of a prize, so the max amount of prizes that Arthur can get is 67.

Therefore, The lie factor is a helpful tool to identify misleading graphs, but it should be used alongside critical thinking and contextual understanding.

The lie factor is a measure of how much a graph distorts the data it represents. It is calculated by dividing the size of the effect shown in the graph by the size of the effect in the data. A lie factor of 1 indicates no distortion, while a lie factor greater than 1 indicates distortion. In practice, the concept of a lie factor can be useful to identify misleading graphs that exaggerate or downplay the significance of the data. However, it should be used in conjunction with other critical thinking skills and contextual understanding to fully evaluate the accuracy and relevance of a graph's message.

Answer:

Therefore, the probability of getting at least 3 tails is 1/16 + 1/4 = 5/16 or 0.3125.

The probability of getting exactly 3 tails is just 1/4, as we calculated above.

Step-by-step explanation:

To find the probability of getting at least 3 tails when tossing a coin 4 times, we need to add the probabilities of getting 3 tails and 4 tails.

The probability of getting a tail on one toss is 1/2, and the probability of getting a head is also 1/2.

The probability of getting 4 tails is (1/2)^4 = 1/16 because there is a 1/2 chance of getting a tail on each toss, and the events are independent, so we multiply the probabilities together.

The probability of getting 3 tails is (4 choose 3) * (1/2)^4 = 4/16 = 1/4 because we need to choose which 3 tosses will be tails (this can be done in (4 choose 3) = 4 ways), and there is a 1/2 chance of each of those tosses being a tail, with a 1/2 chance of the last toss being a head.

To get more than a dollar, Bob needs to earn at least 110 cents. Bob already has 20 cents. He needs to get 9 right to earn over a dollar.

If Bob gets 9 right, Bob would earn 90 cents more. 90 + 20 = 110 cents = $1.1

Algebraic Expression: An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms

Bob correctly answered 12 questions, so

Bob mis-answered 20 questions.

Let x be the number of questions that he correctly answered.

Let y be the number of questions that he answered incorrectly.

Bob's mother promised to give him 10 cents for each accurate response. This implies that he would receive $10x for correctly answering x questions.

Bob's mother informed him that she would deduct $5 for each incorrect response. This implies that if he answers y questions incorrectly, Bob will forfeit.

- $5y.

Bob completed 32 problems, which indicates that

x + y = 32

After solving 32 tasks, Bob received 20 cents, which indicates that

10x - 5y = 20 - - - - - - - - -1

When x = 32 - y is substituted into equation 1, it produces

10(32 - y) - 5y = 20

320 - 10y - 5y = 20

- 10y - 5y = 20 - 320

- 15y = - 300

y = - 300/ -15 = 20

Substituting y = 20 into x = 32 - y, it becomes.

x = 32 - 20 = 12

To get more than a dollar, Bob needs to earn at least 110 cents. Bob already has 20 cents. He needs to get 9 right to earn over a dollar.

If Bob gets 9 right, Bob would earn 90 cents more. 90 + 20 = 110 cents = $1.1

A "required parameter" requires an assigned value for the argument used to call the method, while "optional parameters" do not need to be included in the method call and have a default value assigned to them.

The type of parameter that requires that the argument used to call the method must have an assigned value is a "required parameter".

Required parameters are parameters that must be included in the method call, and the argument passed for the required parameter must have a value assigned to it. If a required parameter is not included in the method call, or if the argument passed for the required parameter does not have a value assigned to it, an error will be thrown.

In contrast, there are also optional parameters, which are parameters that do not need to be included in the method call. If an optional parameter is not included in the method call, the method will use a default value assigned to the parameter.

In many programming languages, the syntax for specifying required and optional parameters in a method or function call is specified using different symbols, such as parentheses or square brackets.

We have,

Consider each partition separately:

Partition 1: {{0}, {1}, {2}, {3}, {4}}

Since each element is in its own subset, there are no elements related to each other.

Therefore, the relation r is empty, and there are no ordered pairs.

Partition 2: {{0, 1}, {2, 3, 4}}

Within this partition, the elements 0 and 1 are in the same subset, and the elements 2, 3, and 4 are in another subset.

Therefore, the ordered pairs in the relation r are:

{(0, 0), (1, 1), (2, 2), (3, 3), (4, 4), (0, 1), (1, 0)}

Partition 3: {{0, 1, 2}, {3, 4}}

B. No, because the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

The Central Limit Theorem (CLT) is a fundamental concept in statistics that states that as the sample size increases, the sampling distribution of the sample means will approach a normal distribution. However, this is only true if certain conditions are met, one of which is having a large enough sample size.
The CLT states that the sampling distribution of x will be approximately normally distributed if the sample size is large enough (usually greater than 30). If the sample size is small, the sampling distribution may not be normally distributed. In such cases, other statistical techniques like the t-distribution should be used.
Furthermore, the CLT assumes that the population being sampled is not necessarily normally distributed, but it does require that the population has a finite variance. This means that even if the population is not normally distributed, the sampling distribution of x will still be approximately normal if the sample size is large enough.
In conclusion, the answer is B, as the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

The directional derivative of the function in the direction of the given vector is positive, indicating that the function is increasing in that direction.

The directional derivative is a measure of the rate of change of a function in a particular direction. To calculate the directional derivative, we need to take the dot product of the gradient of the function with the unit vector in the given direction. The sign of the directional derivative tells us whether the function is increasing or decreasing in that direction.
In this case, we are given that the angle between the vector and a unit vector is 99 degrees. Since the dot product of two vectors is equal to the product of their magnitudes times the cosine of the angle between them, we can write:
cos(99) = (u . v) / (|u| |v|)
where u is the given vector and v is the unit vector. We know that the magnitude of the unit vector is 1, so we can

simplify:
cos(99) = u . v / |u|
Multiplying both sides by |u|, we get:
cos(99) |u| = u . v
This tells us the magnitude of the projection of the vector u onto the unit vector v. If u and v point in the same direction, the projection is positive; if they point in opposite directions, the projection is negative.
Since u is nonzero and the angle between u and v is less than 180 degrees (i.e., they point in the same direction), the sign of the projection is positive.
