Answer: 8 units

Step-by-step explanation:

This can be solved using the Pythagorean Theorem:

c² = a² + b²

c is the hypotenuse

a and b are the sides

Solving for the length:

10² = 6² + b²

100 = 36 + b²

b² = 100 - 36

b² = 64

b = √64

b = 8 units

The missing side is 8 units.

The increasing the sample size by a factor of 25 will reduce the width of the confidence interval by a factor of 5.

a. Suppose we have a two-sided confidence interval for the population mean with known variance, given by the equation:

Cl is the confidence interval, x is the sample mean, σ is the population standard deviation, n is the sample size, and zα/2 is the z-score corresponding to the desired level of confidence.

The σ are fixed for a given level of confidence, we can achieve this by increasing n by a factor of 4.

Specifically, if we increase the sample size from n to 4n, then the new confidence interval will have half the width of the original interval.

b. If the sample size is increased by a factor of 25, then the term √n in the denominator of the above equation will be replaced.

Therefore, increasing the sample size by a factor of 25 will reduce the width of the confidence interval by a factor of 5.

Answer:

I believe it is Kadeem who takes longer by 10 minutes.

Step-by-step explanation:

A person whose speed is slow will take longer to reach so Kadeem takes longer by 0.5 hours.

Given that,
Kadeem and Quinn both drive 25 miles.
Kadeem drives at a constant speed of 50 miles an hour.
Quinn drives at a constant speed of 75 miles an hour.
To determine who takes longer to drive the 25 miles.

Distance is defined as the object traveling at a particular speed in time from one point to another.

Here,
Time is taken by Kadeem to reach 25 miles with a speed of 25 miles per hour
= 25 / 50 = 0.5 hour

Time is taken by Quinn to reach 25 miles with a speed of 75 miles per hour,
= 25 / 75 = 0.34 hour

Thus, a person whose speed is slow will take longer to reach so Kadeem takes longer by 0.5 hours.

The approximate value of the function after the change is approximately 10.9597.

A derivative of a function with respect to an independent variable is what is referred to as differentiation. Calculus's concept of differentiation can be used to calculate the function per unit change in the independent variable. A function of x would be y = f(x).

To find the approximate change in the value of √(2x + 2) as its argument changes from 1 to 27, we can use differentials. Let's denote the function as y = √(2x + 2).

First, let's find the derivative of y with respect to x:

dy/dx = d/dx(√(2x + 2))

To find this derivative, we can use the chain rule. Let u = 2x + 2, so that y = √u. Applying the chain rule:

dy/dx = (1/2√u) * d/dx(u)

      = (1/2√(2x + 2)) * d/dx(2x + 2)

      = (1/2√(2x + 2)) * 2

      = 1/√(2x + 2)

Now, let's find the approximate change in the value of y as x changes from 1 to 27. We can use differentials:

Δy ≈ dy = (dy/dx) * Δx

where Δx = 27 - 1 = 26.

Substituting the derivative we found earlier:

Δy ≈ (1/√(2x + 2)) * Δx

    = (1/√(2*27 + 2)) * 26

    = (1/√56) * 26

    ≈ (1/7.4833) * 26

    ≈ 3.4764

Therefore, the approximate change in the value of √(2x + 2) as its argument changes from 1 to 27 is approximately 3.4764.

To find the approximate value of the function after the change, we can add the approximate change to the initial value of the function:

Approximate value after the change ≈ √(2*27 + 2) + 3.4764

                                 ≈ √56 + 3.4764

                                 ≈ 7.4833 + 3.4764

                                 ≈ 10.9597

Therefore, the approximate value of the function after the change is approximately 10.9597.

Answer:

\(300\div b\) windows

Step-by-step explanation:

We can find how many windows each building has by changing our old expression.

If we assume \(b\) is the amount of buildings and \(w\) is the amount of windows per building, we can make the equation:

\(wb = 300\).

Now we want to isolate w on one side.

To do this we can divide both sides by b.

\(wb\div b = 300\div b\\\\w = 300\div b\)

So the amount of windows per building is \(300 \div b\).

The age of Barbra is 22 years.

The algebraic method for solving simultaneous linear equations is the substitution method. A quantity of one variable through one expression is replaced in the second equation, as the name implies.

Now, according to the question.

Let 'a' be the age of Alice.

Let 'b' be the age of Barbra

Let 'c' be the age of Carol.

The sum of age of all three sisters is 68 years.

Thus,  a + b + c = 68

Now, as Alice is three years younger than Barbra.

a = b - 3

and, Barbra is 5 years younger than Carol.

b = c - 5

c = b + 5

By substitution of values of a and c in total age.

(b - 3) + b + (b + 5) = 68

3b - 3 + 5 = 68

Answer:  the value of f′′′(4) is 3/256.

Step-by-step explanation:

Given the third-degree Taylor polynomial:

f(x) = (x−4)³/512 − (x−4)²/64 + (x−4)⁴/2

To find the value of f′′′(4), we need to differentiate the polynomial three times and evaluate it at x = 4.

First derivative:

f'(x) = 3(x−4)²/512 − 2(x−4)/64 + 4(x−4)³/2

Second derivative:

f''(x) = 6(x−4)/512 − 2/64 + 12(x−4)²/2

Third derivative:

f'''(x) = 6/512 + 24(x−4)/2

Now, substitute x = 4 into f'''(x):

f'''(4) = 6/512 + 24(4−4)/2

= 6/512 + 0

= 6/512

= 3/256

Therefore, the value of f′′′(4) is 3/256.

If Argyle says that she has collected data that only tell her whether the cases are the same or different, one can accurately say that she has collected data on the nominal level.

The nominal level of measurement is the least strict type of data measurement in which the measurements or observations are grouped into distinct categories without a specific order or value structure. At this stage of measurement, variables are defined as categorical because the groups and categories can only be counted, which is usually done using frequencies and proportions.

The nominal level of measurement can take the form of either binary or multichotomous. Binary variables have only two groups, while multichotomous variables have more than two groups. Variables that are frequently used in this level of measurement include gender, race, or political affiliations.

The probability of completing the final examination in one hour or less, given a normal distribution with a mean of 79 minutes and a standard deviation of 8 minutes, is approximately 0.8413.

To find the probability of completing the exam in one hour or less, we need to convert one hour (60 minutes) into z-scores. The formula for calculating the z-score is (x - μ) / σ, where x is the value we want to convert, μ is the mean, and σ is the standard deviation.

In this case, we want to find the z-score for 60 minutes. Substituting the values into the formula, we have (60 - 79) / 8 = -2.375.

Next, we need to find the probability associated with this z-score. We can look up the corresponding probability from a standard normal distribution table or use a calculator. The probability corresponding to a z-score of -2.375 is approximately 0.0087.

However, we are interested in the probability of completing the exam in one hour or less, which includes all values less than or equal to 60 minutes. Since we are dealing with a continuous distribution, we need to consider the area under the curve up to the z-score of -2.375. This area represents the probability of completing the exam in one hour or less.

Looking up the z-score of -2.375 in the standard normal distribution table, we find that the corresponding probability is approximately 0.0087. Therefore, the probability of completing the exam in one hour or less is approximately 0.0087 or 0.8413 (rounded to four decimal places).

Please provide the target stock price to proceed with the calculation and obtain the target FCF at the end of year 1.

To determine the target Free Cash Flow (FCF) at the end of year 1, we need to calculate the FCF for each year based on the given growth rates and other financial information.

Let's break down the calculations step by step:

Calculate the FCF for year 1 using the expected growth rate of 12%:

FCF₁ = FCF₀ * (1 + growth rate) = FCF₀ * (1 + 0.12)

Calculate the FCF for year 2 using the same growth rate:

FCF₂ = FCF₁ * (1 + growth rate) = FCF₁ * (1 + 0.12)

Calculate the FCF for year 3 using the same growth rate:

FCF₃ = FCF₂ * (1 + growth rate) = FCF₂ * (1 + 0.12)

Calculate the FCF for year 4 using the industry growth rate of 5%:

FCF₄ = FCF₃ * (1 + industry growth rate) = FCF₃ * (1 + 0.05)

Given that ABC Co. aims to set the current stock price to $40, we can use the formula for the stock price as a multiple of FCF to determine the target FCF:

Target FCF = Target Stock Price / Stock Price Multiple

To find the stock price multiple, we divide the market value of the company by the FCF:

Stock Price Multiple = Market Value / FCF

The market value can be calculated as follows:

Market Value = (Number of Shares * Stock Price) + Debt - Cash

Substituting the given values:

Market Value = (15 million shares * $40) + $50 million debt - $20 million cash

Finally, we can calculate the target FCF at the end of year 1 using the target stock price and the stock price multiple:
