There are 4 different weekly plans that meet the condition

If Tycho wants to go for a run on the same weekdays every week, there are 7 choices for the first day of the week, 6 choices for the second day of the week, and 5 choices for the third day of the week (since he can't run on two consecutive days).

However, we have to be careful not to overcount the number of plans that meet the conditions. For example, if Tycho chooses Monday and Tuesday as his running days, that's the same as choosing Tuesday and Monday.

To avoid overcounting, let's first count the total number of possible plans, regardless of whether they meet the conditions or not. We can choose any two days of the week for Tycho to run, which can be done in 7 choose 2 ways (or C(7,2) ways), since order doesn't matter.

C(7,2) = 7!/(2!(7-2)!) = 21

So there are 21 possible plans, regardless of whether they meet the conditions or not.

Now let's count the number of plans that meet the conditions. Since Tycho wants to run on two days a week and not on consecutive days, there are only two possible patterns: (1) run on Monday and Thursday, or (2) run on Tuesday and Friday.

Each pattern can be done in 2 ways: either run on Monday and Thursday, or run on Thursday and Monday. Similarly, either run on Tuesday and Friday, or run on Friday and Tuesday.

So there are 4 plans that meet the conditions: (Monday, Thursday), (Thursday, Monday), (Tuesday, Friday), and (Friday, Tuesday).

Lisa would need to serve 12 customers to attain the projected income if Daisy calls in sick that day

What is linear function ?

A linear function is a mathematical function that can be represented by a straight line on a graph. It has the form of:

y = mx + b

where m is the slope of the line, which determines how steeply the line rises or falls, and b is the y-intercept, which is the point where the line crosses the y-axis.

According to the question:
If Daisy calls in sick, then Lisa will be the only stylist at the salon, and all customers will go to her. Let's use x to represent the number of Lisa's customers. Then the income generated by Lisa's customers can be represented by the equation:

18x = projected income

We can solve for x by dividing both sides of the equation by 18:

x = projected income / 18

Substituting the given projected income of $216, we get:

x = 216 / 18 = 12

Therefore, Lisa would need to serve 12 customers to attain the projected income if Daisy calls in sick that day.

The two numbers that fit the description are 27 and 99.

There are two numbers that fit this description. To find them, we can solve the equation:

Difference = Number - Number’s Reverse

Difference = 72

Number - Reverse = 72

Let’s call the two-digit number “x” and its reverse “y”. So, we can rewrite the equation as:

x - y = 72

Now, we can solve the equation using algebraic methods. First, add “y” to both sides of the equation:

x - y + y = 72 + y

x = 72 + y

Next, let’s solve for “y” by subtracting “72” from both sides of the equation:

x - 72 = 72 + y - 72

x - 72 = y

Therefore, we can rewrite the equation as:

x - 72 = y

Now, we can solve for “x” and “y” by plugging in possible values for “x” and “y” and seeing which ones work. Since we’re dealing with two-digit numbers, let’s start with numbers between 10 and 99.

First, let’s try x = 10 and y = 82.

10 - 82 = -72

This doesn’t work, since the difference cannot be negative.

Next, let’s try x = 15 and y = 87.

15 - 87 = -72

Again, this doesn’t work.

Finally, let’s try x = 27 and y = 99.

27 - 99 = -72

This works! So, the two numbers that fit the description are 27 and 99.

As per the given fraction, Kayla has 7/8 pound of flour left in total.

Let's start by looking at the amount of white flour Kayla has. She has 7/8 pounds of white flour, and she uses 3/8 pounds in the recipe. To figure out how much white flour she has left, we need to subtract the amount she used from the amount she had to start with:

7/8 - 3/8 = 4/8

So Kayla has 4/8 pounds of white flour left. But we can simplify this fraction by dividing both the numerator and the denominator by 4:

4/8 ÷ 4/4 = 1/2

So Kayla has 1/2 pound of white flour left.

Now let's look at the wheat flour. Kayla has 4/8 pounds of wheat flour, and she uses 1/8 pound in the recipe. To figure out how much wheat flour she has left, we need to subtract the amount she used from the amount she had to start with:

4/8 - 1/8 = 3/8

So Kayla has 3/8 pound of wheat flour left.

To find out how much flour Kayla has left in total, we need to add the amount of white flour she has left to the amount of wheat flour she has left:

The rate at which the water is being drained from the container is -12.56 cubic inches per second.

Given that the water is being drained from a container which has the shape of a right circular cone. The cone has a radius of 3 inches at the top and a height of 6 inches. When the water is 3 inches deep, the surface level is falling at a rate of 2 inches per second. We need to find the rate at which the water is being drained from the container.

Step 1: Calculate the volume of the cone. Consider the cone with the height h = 6 inches and radius of the base r = 3 inches. Let H be the height of the water and V be the volume of the water in the cone. Let V0 be the volume of the cone.

Cone Volume formula: $V=\frac{πr^{2}h}{3}$V0 = πr²h/3 = (3.14) (3²) (6)/3 = 56.52 cubic inches

Step 2: Find the rate at which the water level is falling. Let the rate at which the water level is falling be dh/dt. When the water is 3 inches deep, the surface level is falling at a rate of 2 inches per second. Thus, dh/dt = -2.

Step 3: Find the rate at which the water is being drained from the containerLet dv/dt be the rate at which the water is being drained from the container. To find this rate we need to differentiate the volume of water with respect to time V = (1/3)πr²H.H²dv/dt = (2/3)πr² dh/dtdv/dt = (2/3)π(3²)(-2) = -12.56 cubic inches per second.

Hence, the rate at which the water is being drained from the container is -12.56 cubic inches per second.

In triangle ΔABC angle m∠A = 38.68°

An angle is the space between of the point of intersection of two rays meeting at a common vertex.

Since we have triangle ΔABC and m∠B = 90 and the ratio BC/AC = 0.625. We desire to find angle A, we proceed as follows.

In  ΔABC, since m∠B = 90, this implies that ΔABC is a right-angled triangle.

Also, the ratio BC/AC = cosC

Since BC/AC = 0.625

⇒ cosC = 0.625

Taking inverse cosine of both sides, we have

C = cos⁻¹(0.625)

= 51.318°

≅ 51.32°

Also in ΔABC

m∠A + m∠B + m∠C = 180°  (sum of angles in a triangle)

So, m∠A = 180° - m∠B - m∠C

= 180° - 90° - 51.32°

= 90° - 51.32°

= 38.68°

So, angle m∠A = 38.68°

The two solutions to e² = 6x using Newton's method are x_left = 1.23151 and x_right = 2.157545.

To find the solutions of e² = 6x using Newton's Method, we will follow these steps:

Let f(x) = e² - 6x. Then we want to find the roots of f(x) = 0, which are the solutions to e² = 6x.

We need to choose a starting point x₀. A good choice is x₀ = 1, since it's a reasonable approximation to the solutions.

Apply Newton's Method to find the next approximation x₁:

x₁ = x₀ - f(x₀)/f'(x₀),

where;

Plugging in the values, we get:

x₁ = x₀ - (e² - 6x₀)/(-6) = x₀ + (e²/6 - x₀)

Use x₁ as the new starting point and repeat the process until we achieve the desired level of accuracy.

In this case, we want to find the solutions to six significant figures, so we will repeat the process until the difference between xₙ and xₙ₋₁ is less than 0.000005 (the sixth decimal place).

Using a calculator, we can apply Newton's Method iteratively to find the two solutions:

Iteration 1:

x₁ = x₀ - f(x₀) / f'(x₀)

x₁ = 1 - (e² - 6)/(-6) = 1.231509

Iteration 2:

x₂ = 1.231509 - (e² - 6)/(-6) = 1.463018

Iteration 3:

x₃ = 1.463018 - (e² - 6)/(-6) = 1.694527

Iteration 4:

x₄ = 1.694527 - (e² - 6)/(-6) = 1.926036

Iteration 5:

x₅ = 1.926036 - (e² - 6)/(-6) = 2.157545

y = -5x² + 5 is the equation of the parabola which has its vertex at (0, 5) and passes through the point (1, 0)

We know that the vertex of the parabola is (0, 5), which means that the equation for the parabola has the form:

y = a(x - 0)² + 5

where 'a' is a constant that determines the shape of the parabola. Since the parabola passes through the point (1, 0), we can substitute these values into the equation and solve for 'a':

0 = a(1 - 0)² + 5

0 = a + 5

a = -5

Therefore, the equation of the parabola is: y = -5x² + 5

This equation represents a parabola that opens downwards (since the coefficient of x² is negative), has a vertex at (0, 5), and passes through the point (1, 0).

This gives us a present value for the company with debt of $35,564 and a present value for the competitor without debt of $36,944. The difference in present values is $1,380, rounded to the nearest dollar. Therefore, the company with debt gives the contract a higher present value of $1,380.

The company with debt will have the higher present value for this contract. This is because, despite having a higher yield, the competitor without debt is only earning 2.3% on their excess money, while the company with debt is earning 8%.

To calculate the difference in present values, we need to first calculate the present value of each company's contract. To do this, we will use the present value formula, which is:

[tex]PV = C / (1 + r)n[/tex]

Where C is the contract amount, r is the rate of return, and n is the number of years. For the company with debt, we can substitute $40,000 for C, 8% for r, and 1.75 for n. For the competitor without debt, we can substitute $40,000 for C, 2.3% for r, and 1.75 for n.

A triangle is a polygon that has three sides, three angles, and three vertices. It is a two-dimensional figure that is formed by connecting three non-collinear points. The three sides of a triangle can be of different lengths or the same length, and the angles can also vary in size. The sum of the three angles of a triangle always adds up to 180 degrees. Triangles can be classified based on their side lengths and angle measurements.

In a right triangle, the sum of the two acute angles is always equal to 90 degrees. Therefore, we can find the missing angle by subtracting the two given angles from 90 degrees.

Let's call the missing angle "x". Then we have:

x + 21 + 20 = 180 (the sum of angles in any triangle is 180 degrees)

x = 180 - 21 - 20

The central limit theorem (CLT) states that for large enough sample sizes, the distribution of the sample means approximates a normal distribution regardless of the shape of the initial population distribution.

It is a statistical theory that clarifies how the mean of a random sample of independent observations drawn from a non-normal population converges in distribution to a normal population.

According to this theory, the sample size should be at least 30 for the sample mean to have an approximately normal distribution. The following are the fundamental assumptions of the central limit theorem:
