It is difficult to make a general statement about whether tennis coaches generally get paid more than football coaches in Jacksonville or elsewhere, as the salaries of coaches are influenced by a Wide range of factors

As an AI language model, I do not have access to up-to-date information about salaries of coaches in Jacksonville. However, in general, the salaries of coaches vary widely depending on a number of factors, such as the type of sport, the level of competition, the location, the success of the team, and the budget of the institution.

In terms of tennis and football, football is generally considered to be a more popular and high-profile sport than tennis in the United States, which could result in higher salaries for football coaches at the collegiate level. Football also typically generates more revenue and has larger budgets for athletic programs, which could also influence the salaries of coaches.

However, there are also factors that could affect the salaries of tennis coaches. For example, if a tennis program has a particularly successful season or has produced successful players, the coach may negotiate a higher salary. Additionally, some colleges may place a greater emphasis on tennis or have larger budgets for tennis programs, which could also impact the salaries of coaches.

Overall, it is difficult to make a general statement about whether tennis coaches generally get paid more than football coaches in Jacksonville or elsewhere, as the salaries of coaches are influenced by a wide range of factors. It is also important to note that salaries can vary widely between individual institutions, even within the same sport, and that negotiations between coaches and their institutions can play a significant role in determining salaries.

The answer is B, I know this because I just took a test with this question lol

If 12 correct answers constitute a passing grade on a 20-item true-false exam, the probability that someone will pass is 1/2 if they are guessing.

Therefore,

Let X denote the number of correctly answered questions out of a total of 20.

Bernoulli trails are formed by repeated coin tosses. Because the "head" on a coin represents the correct answer and the "tail" represents the incorrect answer, the questions that are correctly answered are Bernoulli trials.

\($&\therefore \mathrm{p}=\frac{1}{2} \\\)

\(&\therefore \mathrm{q}=1-\mathrm{p}=1-\frac{1}{2}=\frac{1}{2}\)

X follows a binomial distribution with n = 20 and p = 1/2

\(&\therefore P(X=x)={ }^n C_x q^{n-x} p^x \\\)

\(&={ }^{20} C_x\left(\frac{1}{2}\right)^{20-x} \cdot\left(\frac{1}{2}\right)^x \\\)

\(&={ }^{20} C_x\left(\frac{1}{2}\right)^{20}\)

P ( at least 12 questions answered correctly )= P (X ≥ 12)

\(&=\mathrm{P}(\mathrm{X}=12)+\mathrm{P}\)\((\mathrm{X}=13)+\ldots+\mathrm{P}(\mathrm{X}=20) \\\)

\(&={ }^{20} \mathrm{C}_{12}\left(\frac{1}{2}\right)^{20}+{ }^{20}\)\(\mathrm{C}_{13}\left(\frac{1}{2}\right)^{20}+\ldots+{ }^{20}\)\(\mathrm{C}_{20}\left(\frac{1}{2}\right)^{20} \\\)

\(&=\left(\frac{1}{2}\right)^{20} \cdot\left[{ }^{20} \mathrm{C}_{12}+{ }^{20} \mathrm{C}_{13}+\ldots+{ }^{20} \mathrm{C}_{20}\right]\)

Hence, If 12 correct answers constitute a passing grade on a 20-item true-false exam, the probability that someone will pass is 1/2 if they are guessing.

The complete question is:

In an examination, 20 questions of true-false type are asked. Suppose a student tosses a fair coin to determine his answer to each question. If the coin falls heads, he answers 'true', if it falls tails, he answers 'false'. Find the probability that he answers at least 12 questions correctly.

Approximate solution of the system is:

B. (5/2, -13/4)

Step-by-step explanation:

To approximate the solution of the given system of equations using the graph, we need to find the point where the two lines intersect. Let's analyze the equations and the graph to determine the approximate solution.

The given system of equations is:

-2x + 5y = 19 ...(1)

y = (-5/6)x - (1/6) ...(2)

Looking at equation (2), we can see that it represents a diagonal line with a negative slope, passing through the points (-5, 1) and (6, 6).

Now let's plot this line on the graph:

  |

6  |     x

  |

  |     x

5  |      x

  |

  |        x

4  |

2  |

  |

1  |  x

  |

0  |____________________

 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7

The line rises from (-5, 1) to (6, 6).

Next, let's analyze equation (1), which can be rearranged as:

5y = 2x + 19

y = (2/5)x + (19/5)

Comparing equation (1) with equation (2), we can see that the slope of the line in equation (1) is positive, and it intersects the other line at a point. Therefore, we are looking for the point where the rising diagonal line intersects the line with a positive slope.

By visually examining the graph, we can approximate the intersection point to be around (5/2, -13/4).

Hence, the approximate solution of the system is:

B. (5/2, -13/4)

Answer:

6.2 kilograms/ deciliters

Step-by-step explanation:

megagrams to kilograms

1 megagram = 1000 kilograms

hectoliter to deciliter

1 hectoliter = 1000 deciliter

Using conversion factors

6.2megagrams      1000 kilgrams         1 hectoliter

---------------------- * ----------------------- * -------------------------

hectoliter                  1 megagram       1000 deciliters

Canceling like terms

6.2 kilograms/ deciliters

Answer:

\(\Large \boxed{\mathrm{6.2 \ kilograms/deciliter}}\)

Step-by-step explanation:

1 megagram = 1000 kilograms

6.2 megagrams = x (kilograms)

Cross multiplying.

x = 1000 × 6.2

x = 6200

6.2 megagrams = 6200 kilograms

1 hectoliter = 1000 deciliters

\(\displaystyle \sf \frac{6200 \ kilograms}{1 000\ deciliters }\)

\(\displaystyle \frac{6200}{1000} =6.2\)

6.2 megagrams/hectoliter = 6.2 kilograms/deciliter

Answer:

45 mph

Step-by-step explanation:

Using the equation d = rt, we can rearrange the equation to be t = d/r

Since the amount of time was the same, we can set d/r equal to each other for both speeds.

Let x represent the average speed.

\(\frac{d}{r}\) = \(\frac{d}{r}\)

\(\frac{180}{x}\) = \(\frac{200}{x+5}\)

Cross multiply and solve for x:

200x = 180x + 900

20x = 900

x = 45

So, the average speed was 45 mph

No, this table is not proportional

You can tell if a table shows a proportional relationship by calculating the ratio of each pair of values. If those ratios are, all the same, the table shows a proportional relationship.

Let us understand this by looking at the table provided

1st value is 1/5

2nd value is 3/10

We have to check whether the table is proportional or not

If the 1st value will be equal to the 2nd value then we can say that the table is proportional, otherwise, the table is not proportional

1/5 ≠ 3/10

We can say that table is not proportional. There is no need to check for other values as the condition becomes unsatisfied for the first two values.

f(x) = x^3 - 6x^2 + 12x the function is increasing for x < -2, increasing for x > 4 and decreasing for -2 < x < 4. The critical value that will give you a relative maximum is x = 4. The critical value that will give you a relative minimum is x = -2.

The derivative of the given function is f'(x) = 3x^2 - 12x + 12. Setting this equal to 0 gives us x = 0 and x = 4. By the first derivative test, we can determine that the function is increasing for x < -2, increasing for x > 4 and decreasing for -2 < x < 4. Therefore, the critical value that will give us a relative maximum is x = 4 and the critical value that will give us a relative minimum is x = -2. This can be verified by finding the second derivative of the function, which is f''(x) = 6x -12. Setting this equal to 0 gives us x = 2, which is between the two critical values. Since the second derivative is negative for x < 2, the critical value at x = -2 will give us a relative minimum and since it is positive for x > 2, the critical value at x = 4 will give us a relative maximum.

Slope intercept form

y = 1.25x +-4

Equation of a straight line:

y = mx + b ------(i)

Step by Step Solution:

Step 1: Calculating Slope (m).

m = y2-y1x2-x1

m = -4-10-4

m = -5-4

m = 1.25

Now putting value of m in equation (i)

y = 1.25x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (4,1) for calculating y-intercept:

y = mx + b

1 = 1.25(4) + b

1 = 5 + b

-4 = b

b = -4

Now putting value of b in equation (ii)

y = 1.25x + -4

The firm’s economic value added (EVA), that is, how much value did management add to stockholders’ wealth during 2018 is $0.42 million

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

Net operating profit = (22 million - 19 million)*(1 - 0.36)

                                = $1.92  million

EVA = net operating profit after taxes - invested capital*WACC

       = 1.92 million - 15 million*0.10
