In a random distribution, the variance is similar or equal to the mean. This is because the individuals in the population are randomly distributed, and there is no clear pattern to their distribution. The variance of a random distribution can depend on the species mobility, but it is not necessarily greater than the mean.

A random distribution is a type of distribution in which the individuals are randomly scattered throughout the population. There is no clear pattern to the distribution, and the individuals are not grouped together in any way. The variance of a random distribution is similar or equal to the mean because the individuals are evenly distributed throughout the population.

The variance of a random distribution can depend on the species mobility. For example, a species that is highly mobile, such as a bird, will have a larger variance than a species that is less mobile, such as a fish. This is because the mobile species is more likely to travel to different areas of the population, which will increase the variance of the distribution.

However, the variance of a random distribution is not always greater than the mean. For example, if the population is very small, the variance of the distribution may be less than the mean. This is because there are not enough individuals in the population to create a large variance.

In experimental design, pseudoreplication is often a consequence of:

Small sample size and the increased likelihood of committing a Type I error. When the sample size is small, it is more likely that the results of the experiment will be due to chance. This increases the likelihood of committing a Type I error, which is rejecting the null hypothesis when it is actually true.

The actual physical space over which samples are taken or measurements made being smaller or more restricted than the inference space implicit in the hypothesis being tested. This means that the samples or measurements are not representative of the entire population, which can lead to inaccurate results.

Pseudoreplication can also be caused by inadequate stratification of the sample, which means that the samples are not evenly distributed throughout the population. This can lead to biased results.

Finally, pseudoreplication can be caused by using the wrong type of samples or measurements for the hypothesis being tested. This can lead to results that are not relevant to the hypothesis.

Answer:

\(\displaystyle \frac{d}{dx} \Big [ \frac{3}{x^2} \Big ]=-\frac{6}{x^3}\)

Step-by-step explanation:

We can use either the Power Rule or the Quotient Rule to find the derivative of 3/x².

Rewrite \(\displaystyle \frac{3}{x^2}\) as \(\displaystyle 3\cdot \frac{1}{x^2}\) which is equivalent to \(3\cdot x^-^2\).

Now we can apply the power rule to 3x⁻². Subtract 1 from the exponent and multiply the coefficient by -2.

This can be rewritten as \(\displaystyle -\frac{6}{x^3}\).

Substituting 3 for f(x) and x² for g(x), we get:

Simplify.

Using exponent rules, we can rewrite this as:

This can be rewritten as \(\displaystyle -\frac{6}{x^3}\), which is the same as what we got using the product rule.

Answer:

\(\displaystyle \frac{d}{d x}\left[\frac{3}{x^2}\right] = -\frac{6}{x^{3}}\).

Step-by-step explanation:

Let \(f(x)\) and \(g(x)\) denote two functions of \(x\). Assume that \(g(x) \ne 0\). The quotient rule states that:

\(\displaystyle \frac{d}{d x}\left[\frac{f(x)}{g(x)}\right] = \frac{{f}^\prime(x) \cdot g(x) - f(x) \cdot g^{\prime}(x)}{{(g(x))}^2}\).

In this question:

Find \({f}^{\prime}(x)\) and \({g}^{\prime}(x)\).

Notice that the value of \(f(x)\) is constantly \(3\) regardless of the value of \(x\). By the constant rule, \({f}^{\prime}(x) = 0\).

For \({g}^{\prime}(x)\), consider the power rule:

if \(m\) represents a rational number (such as \(2\),) then by the power rule, \(\displaystyle \frac{d}{d x}\left[{x}^{m}\right] = m\, {x}^{m-1}\).

Apply this rule to find \({g}^{\prime}(x)\).

\(\begin{aligned}{g}^{\prime}(x) &= \frac{d}{d x} \left[x^{2}\right] \\ &= 2\, x^{2 - 1} \\ &= 2\, x\end{aligned}\).

Substitute \(f(x) = 3\), \({f}^{\prime}(x) = 0\), \(g(x) = x^{2}\), and \({g}^{\prime}(x) = 2\, x\) into the quotient rule expression to find \(\displaystyle \frac{d}{d x}\left[\frac{3}{{x}^{2}}\right]\):

\(\begin{aligned}&\; \frac{d}{d x}\left[\frac{3}{{x}^{2}}\right] \quad \genfrac{}{}{0em}{}{\leftarrow f(x) = 3}{\leftarrow g(x) = {x}^{2}} \\ =&\; \frac{d}{d x}\left[\frac{f(x)}{g(x)}\right]\\ =&\; \frac{{f}^\prime(x) \cdot g(x) - f(x) \cdot g^{\prime}(x)}{{(g(x))}^2} \\ =& \; \frac{0 \, x^2 - 3\, (2\, x)}{\left({x}^{2}\right)} \\ =&\; -\frac{6}{x^{3}}\end{aligned}\).

Therefore, \(\displaystyle \frac{d}{d x}\left[\frac{3}{{x}^{2}}\right] = -\frac{6}{x^{3}}\).

The 4-period weighted moving average forecast in period 6 is 125.

Given the following data and 4-period weighted moving average.

The weights of the four periods are, 0.13, 0.18, 0.27, and X, for the OLDEST to NEWEST periods, respectively.

The summation of all four weights is equal to 1. Compute the 4-period weighted moving average forecast in period 6.

Entering the given data and X, the summation of all the weights should equal to 1.

0.13 + 0.18 + 0.27 + X = 1

⇒ 0.58 + X = 1

⇒ X = 1 − 0.58

⇒ X = 0.42

We can use the formula below to calculate the 4-period weighted moving average in period 6:

WMA_6$= (X6 × w1) + (X5 × w2) + (X4 × w3) + (X3 × w4)

WMA_6$= (149 × 0.13) + (120 × 0.18) + (111 × 0.27) + (131 × 0.42)

WMA_6$ = 19.37 + 21.60 + 29.97 + 55.02

WMA_6$ = 125

Therefore, the 4-period weighted moving average forecast in period 6 is 125.

The number of people in a restaurant is a discrete random variable with possible values ranging from 0 to 100, while the time it takes for a light bulb to burn out is a continuous random variable with values spanning a non-negative real interval.

Let us now explain each sub-question in a detailed way:

(a) The number of people in a restaurant that has a capacity of 100 is a discrete random variable. This is because the possible values of the random variable are countable and distinct. The number of people in the restaurant can only take on whole number values from 0 to 100, inclusive. The values 0, 1, 2, ..., 100 represent the possible occupancy levels of the restaurant.

(b) The time it takes for a light bulb to burn out is a continuous random variable. This is because the possible values of the random variable form a continuous interval. The time it takes for a light bulb to burn out can theoretically range from a fraction of a second to infinity. It can take on any non-negative real value within this range. Therefore, the possible values of this random variable span a continuum rather than a countable set of distinct values.

Answer:

Below

Step-by-step explanation:

You need the RADIUS to calculate area.....since diameter is 8, radius is 4 inches

Area = pi r^2

Cost per square inch =  price / area = $12.56 / ( 3.14 *4^2) =  $ 0.25 per in^2

The approximate cost per square inch of the cookie cake is $0.25

To know the total cost to cover an area, multiply the area with the cost per unit of area.

Given that, a circular cookie cake costs $12.56, the diameter of the cookie cake is 8 inches,

We need to determine that, what is the approximate cost per square inch of the cookie cake,

So, the area of the cake = π × radius² [diameter = 2 radius]

= 3.14 × 4²

= 50.24 in²

Since, the cost for the 50.24 in² of the cookie cake is $12.56,

So, the 1 in² of the cookie cake = $12.56 / 50.24 in²

= $0.25

Hence, the approximate cost per square inch of the cookie cake is $0.25

50% of the number of 200.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number = x

15% of x = 60

(15/100)x = 60

x = (60 x 100)/15

x = 400

Now,

65/100 x 40

= 260

Now,

50% of 400

= 50/100 x 400

= 200

Thus,

200 is 50% of 400.

5) Two angles and one side are congruent

6) 1 angle and 1 side are given, and the middle side is Reflexive, so thats also congruent.

Proof by contradiction: Every integer greater than 11 is a sum of two composite numbers.

Step 1: Assume the negation of the statement, which is "There exists an integer greater than 11 that cannot be written as a sum of two composite numbers."

Step 2: Let n be the smallest integer greater than 11 that cannot be written as a sum of two composite numbers. This means that all integers greater than n can be written as a sum of two composite numbers.

Step 3: Since n is not composite, it is either prime or 1. If n is prime, then it cannot be written as a sum of two composite numbers because the sum of two composite numbers is composite. If n is 1, then it cannot be written as a sum of two composite numbers because 1 is not composite.

Step 4: Therefore, n cannot be prime or 1. This means that n must be composite. Since n is composite, it can be written as the product of two numbers a and b, where a and b are greater than 1.

Step 5: Since a and b are greater than 1, they must be composite. Therefore, n can be written as the sum of two composite numbers, a and b. This contradicts the assumption that n cannot be written as a sum of two composite numbers.

Step 6: Therefore, the assumption that there exists an integer greater than 11 that cannot be written as a sum of two composite numbers is false. In other words, every integer greater than 11 can be written as a sum of two composite numbers.

A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100, what is f(6) ?

Since, A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100,we have to find the value of f(6).

Consider

f(n+1) = f(n)-8

Let n =1, we get

f(1+1) = f(2) = f(1) - 8 = 100-8 = 92

Let n =2, we get

f(2+1) = f(3) = f(2) - 8 = 92-8 = 84

Let n =3, we get

f(3+1) = f(4) = f(3)-8 = 84 - 8 = 76

Let n =4, we get

f(4+1) = f(5) = f(4)-8 = 76 - 8 = 68

Let n =5, we get

f(5+1) = f(6) = f(5) - 8 = 68-8 = 60

If firm issues​ commercial paper with $1000000 face-value and pays EAR of​ 7.4%, then amount the firm will receive is $981500.

To calculate the amount the firm receives from issuing the three-month commercial paper, we need to determine the total interest earned over the three-month period.

The Effective Annual Rate (EAR) of 7.4% indicates the annualized interest rate. Since the commercial paper has 3-month term, we adjust the EAR to account for the shorter period.

To find the quarterly interest rate, we divide the EAR by the number of compounding periods in a year. In this case, since it is a 3-month period, there are 4-compounding periods in a year (quarterly compounding).

Quarterly interest rate = (EAR)/(number of compounding periods)

= 7.4%/4

= 1.85%,

Now, we calculate interest earned on "face-value" of $1,000,000 over 3-months,

Interest earned = (face value) × (quarterly interest rate)

= $1,000,000 × 1.85% = $18,500,

So, amount firm receives from issuing 3-month commercial paper is the face value minus the interest earned:

Amount received = (face value) - (interest earned)

= $1,000,000 - $18,500

= $981,500.

Therefore, the amount that firms receives is $981500.
