The following table shows the number of heartbeats for four animals for example if it's heartbeat 225 in 3 minutes what animals heart beats ate a rate of 65 beats per minute?

The measure of the arc TQ is 180°.

Given that a circle with an angle subtended outside is 38° and a small arc of 104°, we need to determine the measure of arc TQ.

So, according to the property of a circle, we have,

m ∠R = 1/2 [m arc TQ - m arc SQ]

38° × 2 = m arc TQ - 104°

76° = m arc TQ - 104°

m arc TQ = 76° + 104°

m arc TQ = 180°

Hence the measure of the arc TQ is 180°.

Mat must bowl 140 in the next game.

In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.

Given:

Matt bowled games of 162, 170, and 148.

Average = 155

let the score on fourth game be x.

So, (162 + 170 + 148 + x)/4 = 155

480 + x= 620

x= 140

Thus, he must bowled 140.

First, what is an equation?

➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.

Or, LHS = RHS

Example:- 3x - 5 = x + 8

An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.

Solving an equation:-

To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.

Example:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ Rules for solving an equation by the substitution method:-

Rule ❶ 

If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8

Rule ❷

If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2

Rule ❸ 

If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4

Now consider the algebraic expression 5x - 2y

This expression consists of variables x and y.

Now if :-

⠀⠀⠀⠀⠀⠀⠀⠀

The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Looks like the system is

x + 4y - z = -14

5x + 6y + 3z = 4

-2x + 7y + 2z = -17

or in matrix form,

\(\mathbf{Ax} = \mathbf b \iff \begin{bmatrix} 1 & 4 & -1 \\ 5 & 6 & 3 \\ -2 & 7 & 2 \end{bmatrix} \begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} -14 \\ 4 \\ -17 \end{bmatrix}\)

Cramer's rule says that

\(x_i = \dfrac{\det \mathbf A_i}{\det \mathbf A}\)

where \(x_i\) is the solution for i-th variable, and \(\mathbf A_i\) is a modified version of \(\mathbf A\) with its i-th column replaced by \(\mathbf b\).

We have 4 determinants to compute. I'll show the work for det(A) using a cofactor expansion along the first row.

\(\det \mathbf A = \begin{vmatrix} 1 & 4 & -1 \\ 5 & 6 & 3 \\ -2 & 7 & 2 \end{vmatrix}\)

\(\det \mathbf A = \begin{vmatrix} 6 & 3 \\ 7 & 2 \end{vmatrix} - 4 \begin{vmatrix} 5 & 3 \\ -2 & 2 \end{vmatrix} - \begin{vmatrix} 5 & 6 \\ -2 & 7 \end{vmatrix}\)

\(\det \mathbf A = ((6\times2)-(3\times7)) - 4((5\times2)-(3\times(-2)) - ((5\times7)-(6\times(-2)))\)

\(\det\mathbf A = 12 - 21 - 40 - 24 - 35 - 12 = -120\)

The modified matrices and their determinants are

\(\mathbf A_1 = \begin{bmatrix} -14 & 4 & -1 \\ 4 & 6 & 3 \\ -17 & 7 & 2\end{bmatrix} \implies \det\mathbf A_1 = -240\)

\(\mathbf A_2 = \begin{bmatrix} 1 & -14 & -1 \\ 5 & 4 & 3 \\ -2 & -17 & 2 \end{bmatrix} \implies \det\mathbf A_2 = 360\)

\(\mathbf A_3 = \begin{bmatrix} 1 & 4 & -14 \\ 5 & 6 & 4 \\ -2 & 7 & -17 \end{bmatrix} \implies \det\mathbf A_3 = -480\)

Then by Cramer's rule, the solution to the system is

\(x = \dfrac{-240}{-120} \implies \boxed{x = 2}\)

\(y = \dfrac{360}{-120} \implies \boxed{y = -3}\)

\(z = \dfrac{-480}{-120} \implies \boxed{z = 4}\)

Step-by-step explanation:

The correct answer is b. independent variable = study environment,

dependent variable = test score

The F-ratio is applicable in research situations involving analysis of variance (ANOVA) or comparing the means of multiple groups. It quantifies the variability between groups compared to the variability within groups. To calculate the F-ratio, one needs to determine the mean square values by dividing the sum of squares by the respective degrees of freedom, and then compute the ratio of the mean square between groups to the mean square within groups.

The F-ratio is typically calculated for situations involving analysis of variance (ANOVA) or comparing the means of multiple groups. In the given research situations, the F-ratio would be calculated for:

b. independent variable = study environment,

dependent variable = test score

For this scenario, if there are multiple study environments (e.g., different classrooms, online vs. in-person), and the researcher wants to determine if there are any significant differences in test scores across these environments, an ANOVA test can be conducted to calculate the F-ratio. This test compares the variability between the groups (study environments) with the variability within the groups to determine if there are significant differences in the mean test scores.

The other research situations mentioned (a, c, and d) involve independent variables with a single category or continuous dependent variables, which do not require calculating an F-ratio for their analysis.

Answer:

Step-by-step explanation:

The first one is equal to.  203/203 is equal to 1.  1 times any number is itself.

The second on is less than.  9/37 is a proper fraction and when a number is multiplied by a proper fraction, it gets smaller.

The probability of winning in the described dice game can be calculated by considering the possible outcomes and their corresponding probabilities.

On the first roll, there are three favorable outcomes to win: rolling a total of 7 or 11. There are 36 equally likely outcomes in total (since each die has 6 faces and there are two dice), so the probability of winning on the first roll is 3/36 or 1/12.

If a point is established (any number other than 2, 3, 7, 11, or 12), the game continues. In this case, there are two ways to win: rolling the point value before rolling a 7. The probability of rolling the point before a 7 depends on the specific point value.

For example, if the point is 4, there are 3 ways to win (rolling a 4) and 6 ways to lose (rolling a 7), so the probability of winning in this case is 3/9 or 1/3.

To calculate the overall probability of winning, we need to consider both the probability of winning on the first roll and the probability of winning after establishing a point. These probabilities need to be weighted based on the likelihood of each scenario.

Since the probability of establishing a point on the first roll is 1 - (3/36 + 2/36) = 31/36, the overall probability of winning can be calculated as follows:

Probability of winning = (1/12) + (31/36) * (probability of winning after establishing a point)

The probability of winning after establishing a point depends on the specific point value and the number of ways to win and lose from that point. This probability varies depending on the point and can be calculated individually.

By combining the probabilities of winning from the first roll and winning after establishing a point for all possible point values, we can determine the overall probability of winning in the dice game.

Assuming that a randomly selected subject is given a bone, it seems that we need to consider the context and determine the implications or consequences of this action. Without further information, it is difficult to provide a specific explanation or analysis. However, we can discuss some general possibilities and considerations related to giving a bone to a subject.

1. Medical Treatment: Giving a bone could be related to medical treatment or procedures. For example, in orthopedic medicine, bones may be used for grafting or reconstructive surgeries to repair damaged or fractured bones.

2. Nutritional Benefits: Bones, such as beef or chicken bones, can be used to make broths or stocks that are rich in nutrients like collagen, calcium, and other minerals. These bone-based products are often consumed for their potential health benefits.

3. Animal Care: Giving a bone to an animal, particularly dogs, is a common practice. Bones can serve as a form of entertainment or enrichment for pets, satisfying their chewing instincts and providing dental benefits.

4. Symbolic Meaning: In certain cultures or traditions, bones can hold symbolic meanings. They may be used in rituals, ceremonies, or artistic expressions to represent various concepts, such as strength, mortality, or spirituality.It's important to note that the above interpretations are speculative and based on general assumptions.

The city's average rainfall in November was 5.7 inches.

Seattle, Washington, is famous for its rainy climate. Winter is the rainiest season there. From November through December, the city gets an average of 5.85 inches of rain each month. Seattle usually gets 6 inches of rain in December. We have to find the city's average rainfall in November.

Let the city's average rainfall in November be represented by the variable "x". An average is a single number that represents a set of numbers, generally the sum of the numbers divided by the number of numbers in the set. We can use the equation given below.

A = (R1 + R2)/2

5.85 = (x + 6)/2

x + 6 = 11.7

x = 5.7

Hence, the city's average rainfall in November is 5.7 inches.

The factored form of the given quadratic equation y = x^2 - 5x - 36 is y = (x - 9) (x + 4) and the x-intercepts of the given quadratic equation y = (x - 9) (x + 4) is (9, 0) and (-4, 0).

We are given a quadratic equation:

y = x^2 - 5x - 36

Let us factorize using the middle-term split method.

y = x^2 - 5x - 36

y = x^2 - 9x + 4x - 36

y = x (x - 9) + 4 (x - 9)

y = (x - 9) (x + 4)

So, the factorized form is y = (x - 9) (x + 4).

For x-intercepts, y should be zero.

So,

0 = (x - 9) (x + 4)

(x - 9) = 0 or (x + 4) = 0

x = 9 os  x = -4

So, the x-intercept will be (9, 0) and (-4, 0).

Thus, the factored form of the given quadratic equation y = x^2 - 5x - 36 is y = (x - 9) (x + 4) and the x-intercepts of the given quadratic equation y = (x - 9) (x + 4) is (9, 0) and (-4, 0).

The minimum sample size for the given event to have a normal approximation has to be 13 people.

For normal approximation,

np or n(1-p) should be greater than 10

where,

n = the sample size

p = probability for the occurrence of the event

Here, 20% of ohio residents support the legalization of marijuana

p = 20% or, 2/10

Hence,

1 - p = 1 - 2/10

= 8/10

Therefore, for normal approximation to be used

either n X 2/10 > 10    or,      n X 8/10 > 10

Therefore,

n X 2 > 10 X 10            or,      n X 8 > 10 X 10

hence,

n > 100/2                      or,               n > 100/8

n >  50                          or,               n > 12.5

Since we need to find the minimum no. of sample size to be required we will consider
