Statistics indicate that 45% of all small businesses fail after three years. This is a concerning statistic for entrepreneurs who are considering starting their own business.

It is important for potential business owners to understand the reasons why small businesses fail and take steps to mitigate these risks. Some common reasons for failure include poor management, insufficient funding, lack of market demand, and competition.

One way to mitigate these risks is by having a solid business plan in place that includes a realistic assessment of the market, a clear understanding of the competition, and a plan for securing financing. Additionally, having a strong risk tolerance and the ability to adapt to changing market conditions can also increase the chances of success for small businesses.

Ultimately, the key to success for small businesses is a combination of careful planning, strong management, and a willingness to take calculated risks.

One of the contributing factors to this failure rate is the business owner's risk tolerance (3) B), which may lead them to take on more financial obligations than they can handle. Additionally, securing proper financing (4) D) is crucial for the success and growth of a small business, and a lack of adequate funding may contribute to the high failure rate.

The correct statements are:

b. The population variances for each of the cells should be equal (i.e., there is homogeneity of variance).

c. The populations from which the samples are taken for a two-way ANOVA must be distributed normally.

In a two-way ANOVA, there are several assumptions that need to be met for valid statistical inference. Two of these assumptions are the equality of population variances and the normal distribution of populations.

b. The assumption of homogeneity of variance states that the population variances for each combination of levels of the two factors in a two-way ANOVA should be equal. Violation of this assumption can lead to biased results and affect the validity of the statistical test.

c. The assumption of normality states that the populations from which the samples are taken should follow a normal distribution. This assumption is important because the validity of the F-test used in ANOVA is based on the assumption of normality. Departures from normality can impact the accuracy and reliability of the results.

a. The statement in option (a) is not true. The two-way ANOVA is not robust to violations of the assumptions of sampling from normal distributions and homogeneity of variance, even if the samples are of equal size. Violations of these assumptions can lead to inaccurate and unreliable results.

d. The statement in option (d) is also not true. If the assumptions of a two-way ANOVA are violated, it does not necessarily mean that the researcher should conduct two separate one-way ANOVAs. There are alternative non-parametric tests or robust ANOVA methods that can be used in such cases. The choice of appropriate statistical analysis depends on the nature of the data and the specific research question.

Step-by-step explanation:

If we consider a point on the line (x, y ) then the corresponding point on the inverse, the other line will be (y, x )

A function and its inverse are reflections in the line y = x

Consider the point (1, 5 ) on the red line, the corresponding point on the blue line will be (5, 1 )

This is the case in graph B

The graph showing a function and its inverse is the graph D.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

The graph of a function and its inverse are symmetric with respect with the line y = x.

On each graph you are given, plot the line y = x. If the two functions are symmetric with respect to the line y = x, then the graph does show a function and its inverse.

The probability that X is greater than 145.28 is approximately 0.0465.

Given that X is normally distributed with mean (μ) of 110 and standard deviation (σ) of 21. We are to find the probability that X is greater than 145.28. It can be calculated as follows: We can calculate the Z-score value with the help of the following formula, Z = (X - μ) / σWhere X is the random variable value, μ is the mean, and σ is the standard deviation. Substituting the values in the formula, we get: Z = (145.28 - 110) / 21Z = 1.68476 Using the Z-table, we can find the probability that X is greater than 145.28 as follows: From the Z-table, we get: P(Z > 1.68) = 0.0465

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.

Answer:

Step-by-step explanation:

y = mx + b

Take any two points and set up 2 equations with 2 unknowns.

I'll start with the first two

y = 4x + b

410 = 4x + b                    (1)

440 = 6x + b                   (2)

Subtract (1) from (2)

440 = 6x + b

410 = 4x + b            Subtract

30  = 2x                  Divide by 2

30/2 = 2x/2

Answer: D

Step-by-step explanation:

To determine the maximum number of stories that can be constructed before friction losses prevent proper valve operation, we need to calculate the pressure loss due to friction as the water flows through the piping to each floor.

Using the Hazen-Williams formula, which is commonly used for sizing water supply systems:

P = (4.52Q1.85L10.67/C1.85)d4.87

where:

P = pressure loss due to friction (psi)

Q = flow rate (gpm)

L = length of pipe (feet)

C = Hazen-Williams coefficient (dimensionless)

d = inside diameter of pipe (inches)

Assuming the flow rate is 10 gpm, the length of pipe from floor to floor is the height of the building divided by the number of stories, and the inside diameter of the pipe is 4 inches (since 4 type-L copper corresponds to a 4-inch nominal diameter), the pressure loss for each story can be calculated using a Hazen-Williams coefficient of 130 for copper piping:

P = (4.52 x 10^1.85 x (1 story height/number of stories)10.67/1301.85)4.87

P = 3.3 x (1/number of stories)^1.85

For example, for a 2-story building, the pressure loss would be:

P = 3.3 x (1/2)^1.85

P = 1.6 psi

To ensure that the minimum working pressure of 25 psi is maintained at each flush valve, the pressure loss for each story cannot exceed 25 - 50 = -25 psi (since lower pressures can cause valve malfunctions).

Solving for the maximum number of stories:

3.3 x (1/number of stories)^1.85 <= -25

(1/number of stories)^1.85 <= -25/3.3

1/number of stories <= (-25/3.3)^0.54

number of stories >= 1/(-25/3.3)^0.54

number of stories >= 6.7

Therefore, the maximum number of stories that can be constructed before friction losses prevent proper valve operation is D. This floor only.

A box indicates a 90° angle.

So to find m<a, we can setup the equation 41 + a = 90.

Now subtract 41 from both sides to get a = 49.

There are 72 multiples of 9³ that are greater than \(9^4\) and less than \(9^5\).

We have,

The values of 9³, \(9^4\), and \(9^5\):

9³ = 729

\(9^4\) = 6561

\(9^5\) = 59049

Now,

The multiples of 729 that fall within the range (6561, 59049).

The number of multiples can be calculated as follows:

Multiples = (Highest value ÷ Divisor) - (Lowest value ÷ Divisor)

= (59049 ÷ 729) - (6561 ÷ 729)

= 81 - 9

= 72

Therefore,

There are 72 multiples of 9³ that are greater than \(9^4\) and less than \(9^5\).

x - intercepts: 2 and -1/2

Point = (3, -14)

quadratic formula:

y = a(x -2)(x + 1/2)

we need to solve for a.

-14 = a(3 - 2)(3 + 1/2)

-14 = a(7/2)

a = - 4

so:

y = -4(x -2)(x + 1/2)

y = -4x^2 + 6x + 4

b)

x - intercept = -2 = (-2, 0)

point: (-1, 4)

We can plug both points into two separated equations, as follows:

4 = a(-1)^2 + b(-1) + c (EQUATION 1.)

0 = a(-2)^2 + b(-2) + c (I'll multiply this equation by -1 in order to add the 2 equations together and get rid of c)

4 = a - b + c

0 = -4a + 2b - c

4 = -3a + b

a = 1/3b - 4/3**

What is Scale Drawing?

The Scale drawing that has been scaled up or down from its original size.

According to question

let the scale of drawing is K centimeters/meters

Now

We know that

(Scale of drawing)*Actual Length = Length in scale Drawing

⇒ K centimeters/meters * Actual Length = 16 centimeters

⇒ Actual Length = 16/K meters

(Scale of drawing)*Actual Width = Width in scale Drawing

⇒ K centimeters/meters * Actual Length = 8 centimeters

⇒ Actual Width = 8/K meters

Given that Actual area is 72 square meters

therefore

⇒ Length * Width = Area

⇒ 16/K * 8/K = 72

⇒ 128/K² = 72

⇒ 1/k² = 72/128

⇒ k² = 128/72

The general solution of the differential equation is: y = y_h + y_p

= c_1 cos(θ) + c_2 sin(θ) + (1/2) ln|cos(θ)| cos(θ) - (1/2) tan(θ) csc(θ) sin(θ) - (1/2) ln|cos(θ)| sin(θ) - (1/2) sec(θ).

The characteristic equation of the homogeneous part of the differential equation is given by:

r^2 + 1 = 0

which has the roots r = ±i. Thus, the general solution of the homogeneous part is:

y_h = c_1 cos(θ) + c_2 sin(θ)

To find the particular solution using the method of variation of parameters, we assume that:

y_p = u(θ)cos(θ) + v(θ)sin(θ)

where u(θ) and v(θ) are functions to be determined.

Taking the first and second derivatives of y_p, we get:

y'_p = u' cos(θ) - u sin(θ) + v' sin(θ) + v cos(θ)

y''_p = -u cos(θ) - 2u' sin(θ) - v sin(θ) + 2v' cos(θ)

Substituting these expressions into the differential equation, we get:

-u cos(θ) - 2u' sin(θ) - v sin(θ) + 2v' cos(θ) + u cos(θ) + v sin(θ) = sec(θ) tan(θ)

Simplifying and collecting like terms, we get:

-2u' sin(θ) + 2v' cos(θ) = sec(θ) tan(θ)

Dividing both sides by 2cos(θ), we get:

u' tan(θ) - v' sec(θ) = (1/2) tan(θ)

Now, we need to find u(θ) and v(θ) such that the left-hand side of the above equation satisfies the integrating factor e^(-ln|cos(θ)|) = |cos(θ)|^(-1). Multiplying both sides of the equation by this integrating factor, we get:

u' sin(θ)/|cos(θ)| - v' = (1/2) tan(θ)/|cos(θ)|

Integrating both sides with respect to θ, we get:

u(θ) = (1/2) ln|cos(θ)| - (1/2) tan(θ)csc(θ) + C1

v(θ) = -(1/2) ln|cos(θ)| - (1/2) sec(θ) + C2

where C1 and C2 are constants of integration.

Therefore, the general solution of the differential equation is:

y = y_h + y_p

= c_1 cos(θ) + c_2 sin(θ) + (1/2) ln|cos(θ)| cos(θ) - (1/2) tan(θ) csc(θ) sin(θ) - (1/2) ln|cos(θ)| sin(θ) - (1/2) sec(θ)

where c_1 and c_2 are arbitrary constants.
