What is Simpson's 1 3rd rule?

1) The value of P(A∩B) = 0.

2) The value of P(A|B) = 0.

3) P(A|B) is not equal to P(A). A and B are independent events.

4) The statement "Mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent." is not accurate.

5) We can conclude that mutually exclusive events have a probability of intersection of zero and are not independent.

1) Since A and B are mutually exclusive, they cannot occur at the same time, so P(A∩B) = 0.

2) The conditional probability of A given B is defined as the probability of A occurring given that B has occurred. Since A and B are mutually exclusive, if B has occurred, then A cannot occur. Therefore, P(A|B) = 0.

3) No, P(A|B) is not equal to P(A). Since B has occurred, the sample space has been reduced to only those outcomes in which B has occurred. Therefore, the probability of A given that B has occurred can only be determined from the portion of the sample space in which both A and B occur.

However, since A and B are mutually exclusive, this probability is zero. Therefore, P(A|B) ≠ P(A).

4) The statement is not accurate. Mutually exclusive events and independent events are different concepts. Two events are mutually exclusive if they cannot occur at the same time, whereas two events are independent if the occurrence of one event does not affect the probability of the other event.

If two events are mutually exclusive, they are not independent because the occurrence of one event precludes the occurrence of the other event.

5) Mutually exclusive events have a relationship where if one event occurs, the other cannot. In contrast, independent events are events where the occurrence of one event does not affect the probability of the other event occurring.

Therefore, we can conclude that mutually exclusive events and independent events are not the same concept, and we must be careful not to confuse them.

The experimental probability of rolling a 5 is 25/56, or 0.446.

Probability is a field of mathematics that deals with the chance of certain events happening. It is used to calculate the likelihood of different outcomes in a given situation. Probability helps to make decisions for a variety of real-world applications, such as predicting the weather, deciding whether to invest in stocks and calculating insurance rates. Probability is based on the idea that all outcomes are equally likely, and can be expressed as a number between 0 and 1, where 0 means something is impossible and 1 means something is certain.

The experimental probability is calculated by taking the total number of times a number was rolled and dividing it by the total number of rolls. In this case, the total number of times a 5 was rolled is 25, and the total number of rolls is 56. Therefore, the experimental probability of rolling a 5 is 25/56, or 0.446.

Each point on the least-squares regression line represents a predicted y-value at a given x-value, based on the relationship between the two variables determined through regression analysis.

Regression is a statistical method used to analyze and understand the relationship between two variables. The least-squares regression line is a line of best fit that helps predict the value of one variable based on the value of another.

The correct answer is C, each point on the least-squares regression line represents the predicted y-value at the corresponding value of x.

The line is created by minimizing the sum of the squared differences between the actual y-values and the predicted y-values.

In other words, the line is chosen such that the average difference between the actual and predicted y-values is as small as possible.

Mathematically, the regression line is represented by an equation of the form

=> y = b0 + b1x,

where b0 and b1 are coefficients determined by minimizing the sum of squared residuals.

The predicted y-value for a given x can then be found by plugging in the x-value into the equation.

The required value of c is 9 so that [tex]f(c) =20[/tex] is true, where the function is defined by the equation f(x)=3x-7.

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

To determine the value of c such that [tex]f(c) = 20[/tex], we can simply substitute in the given equation and solve for c.

So, we have:

[tex]f(c) = 3c - 7[/tex]

And, we know that [tex]f(c) = 20[/tex], so we can substitute to get:

20 = 3c - 7

Adding 7 to both sides, we get:

27 = 3c

The first four terms of the arithmetic sequence are -3, 4, 11, 18.

If the first term of an arithmetic sequence is -3 and the common difference is 7, then we can use this formula to find the nth term of the sequence:

Un = a + (n - 1)d

Where

Un is the nth term

a is the first term

d is the common difference, and

n is the position of the term in the sequence.

To find the first four terms of the sequence, we can substitute n = 1, 2, 3, 4 into the formula and solve for Un:

n = 1:

U1 = -3 + (1 - 1)7 = -3

n = 2

U2 = -3 + (2 - 1)7 = 4

n = 3

U3 = -3 + (3 - 1)7 = 11

The characteristics of the given parabola f(x) = -3x² are, A. Compression by 3, reflected over the x-axis.

A parabola is a cross-section cut out of the cone and represented by an equation.

Here,
The general form of a parabola is f(x) = ax² + bx + c, where a, b, and c are constants. In this case, the given equation is f(x) = -3x², which means that a = -3, b = 0, and c = 0.

Answer: The surface area of a sphere can be calculated using the formula:

A = 4 * π * r^2

Where r is the radius of the sphere.

The diameter of the sphere is 36 cm, so the radius can be found by dividing the diameter by 2:

r = 36 cm / 2 = 18 cm

Now that we have the radius, we can plug it into the formula:

A = 4 * π * r^2 = 4 * π * (18 cm)^2 = 4 * π * 324 cm^2 = 1296 * π cm^2

Since π is approximately equal to 3.14, we can get an approximate answer:

A ≈ 1296 * 3.14 = 4071.84 cm^2

So the surface area of the sphere with a diameter of 36 cm is approximately 4071.84 square centimeters.

One daylily costs $9, and one pot of ivy costs $9.

Step-by-step explanation:

Step 1: Write a System of Algebraic Equations

We are given 2 different variables, or "unknowns", that we need to find the value of here - the cost of one daylily, and the cost of one pot of ivy. We know that the cost of each plant remains constant (doesn't change), and we are given the following information:

We can see that we have a system of equations in the making. The first thing to do when writing a system is assign letters to variables. Let's let the cost of one daylily be denoted as [tex]d[/tex], and the cost of one pot of ivy be denoted as [tex]i[/tex] (in dollars for each). From the above information, we can write the system:

[tex]d+8i=81 \hspace{0.8cm} (1)\\10d+11i=189 \hspace{0.1cm} (2)[/tex]

Step 2: Solve the System (with Substitution)

Now that we have a solution, let's use it to solve for the value of each variable. There are many ways to do this (addition, subtraction, etc), but it seems that the quickest way to solve this particular system is using the substitution method. This is where you write one variable in terms of the others by manipulating one equation, and then substituting that expression in for the isolated variable in the other equation. It's easy to do this here because we already have a [tex]d[/tex] in (1).

Isolating [tex]d[/tex] in (1) by subtracting [tex]8i[/tex] from both sides, we get:

[tex]d+8i=81\\d=81-8i\hspace{0.5cm} (3)[/tex]

Substituting (3) into (2) and solving for i, we get:

[tex]10d+11i=189\\10(81-8i)+11i=189\\810-80i+11i=189\\810-69i=189\\-69i=-621\\\bf i=9[/tex]

Substituting this value into (3), we get:

[tex]d=81-8i\\=81-8*9\\=81-72\\=\bf9[/tex]

Therefore, one daylily costs $9, and one pot of ivy costs $9.

A) Iker started running 24 laps on the track each week. This is mentioned in the question.

B) Iker ran 11 more laps each week.

C) The equation for this situation would be: y = 11x + 24

To find out how many more laps he ran each week, we can subtract the number of laps he ran on the first week from the number of laps he ran on the second week: 35 - 24 = 11 So, Iker ran 11 more laps each week.

To write an equation that models this type of growth, we can use the following formula: y = mx + b

Where y is the number of laps he runs, m is the number of additional laps he runs each week, x is the number of weeks, and b is the number of laps he started running.

In this case, m = 11 (the number of additional laps he runs each week) and b = 24 (the number of laps he started running).

So the equation for this situation would be: y = 11x + 24 This equation shows that the number of laps Iker runs each week (y) is equal to 11 times the number of weeks (x) plus the number of laps he started running (24).
