It is not possible for a study to have practical significance without statistical significance because statistical significance provides evidence that the observed effect is unlikely to have occurred by chance.

The Practical significance and statistical significance are two different concepts that are often used in hypothesis testing.

The Statistical significance refers to the probability that the observed results of a study occurred by chance, given a particular level of significance or alpha.

The Practical significance refers to whether the observed effect size is large enough to be meaningful in a real-world context.

It is possible for a study to have statistical significance without practical significance. For example, a study may find a statistically significant difference between two groups, but the difference may be so small that it is not meaningful in practice.

Answer:

Nine less than a number

Step-by-step explanation:

The probability of finding a sample mean (Y¯) of 1.5 ounces or more when the liquor tax has no impact on consumption (µ = 0). To determine this probability, we would use the Central Limit Theorem and the z-score formula.

Since the population mean (µ) is 0, we'll need to know the population standard deviation (σ) and the sample size (n) to proceed. Without these values, it's impossible to provide an exact probability. However, I can explain the general process.

First, you would calculate the standard error (SE) using the formula SE = σ / √n. Next, you would find the z-score, which is the difference between the sample mean (Y¯) and the population mean (µ) divided by the standard error: z = (Y¯ - µ) / SE.

Once you have the z-score, you can look it up in a standard normal distribution table or use a calculator to find the probability associated with it. In this case, you're looking for the probability of finding a sample mean of 1.5 ounces or more, which corresponds to the area to the right of the z-score in the distribution.

Answer:

s=16, p = 32

s is shirt and p is pants.

s+p=48

since the cost of the shirt and the pants together is $48

p=2s

the cost of the pants was 2 times as much as the shirt.

substitute p in s+p=48

s+2s=48

3s=48

divide both sides by 3

s=16

The shirt costs 16.

now substitute 16 in for s in p=2s

p=2*16

By differentiating the polynomial function, finding the critical points, and evaluating the function at these points and the endpoints, we can determine the maximum and minimum values of the polynomial function.

To find the maximum and minimum of a polynomial function, follow these steps:

1. Differentiate the polynomial function to find its derivative.

2. Set the derivative equal to zero and solve for the critical points.

3. Evaluate the polynomial at the critical points and the endpoints of the interval to determine the maximum and minimum values.

To find the maximum and minimum of a polynomial function, we start by differentiating the function. The derivative represents the rate of change of the function and helps us identify the critical points where the function may reach its extreme values.

Once we have the derivative, we set it equal to zero to find the critical points. Solving this equation gives us the x-values where the function may have a maximum or minimum. Additionally, we need to consider the endpoints of the interval over which we are analyzing the function.

After obtaining the critical points and the endpoints, we evaluate the polynomial at these values to determine the corresponding y-values. The highest y-value corresponds to the maximum of the function, while the lowest y-value corresponds to the minimum.

By differentiating the polynomial function, finding the critical points, and evaluating the function at these points and the endpoints, we can determine the maximum and minimum values of the polynomial function. This method allows us to analyze the behavior of the function and identify its extreme points.

Answer:

x = -11.2

Step-by-step explanation:

0.1 + 0.2x + 0.3 + 0.05x = -2.4

Combine like terms on the left side.

0.25x + 0.4 = -2.4

Subtract 0.4 from both sides.

0.25x = -2.8

Divide both sides by 0.25.

Step-by-step explanation: 1/5 of 30 is 6 so if Sali gets 1/5 then Sali should get 6 cakes. 10% of 30 is 3 so if Jane gets 10% then she should get 3 cakes. Sali and Jane together get 9 cakes so Simon has 21 cakes left.

Answer:

$345.60

Step-by-step explanation:

From the above question,

P = Principal = $200

R = Interest rate = 20%

T = Time in years = 3 years

n = Number of times interest is compounded = Annually = 1

First, convert R as a percent to r as a decimal

r = R/100

r = 20/100

r = 0.2 rate per year,

Then solve the equation for A

The formula =

A = P(1 + r/n)^nt

A = 200.00(1 + 0.2/1)^(1×3)

A = 200.00(1 + 0.2)^(3)

A = $345.60

Therefore, the total amount that Molly will have in her account at the end of 3 years is $345.60

Division involves the dividend divided by the divisor which results in the quotient.

Division operation is one of the four basic mathematical or algebraic operations, including addition, multiplication, and subtraction.

There are five parts to a division operation, including the dividend (the numerator or number being divided), the divisor (the denominator or number dividing), the division operand (÷), the equation symbol (=), and the product.

Thus, to divide a value, quantity, expression, or number, use the divisor as the denominator and the result becomes the quotient.

(A) dy/dx = - x/y will be the differential equations will a slope field show nothing but negative slopes in the fourth quadrant.

The slope field is utilized when you want to see the tendencies of solutions to a DE, given that the solutions pass through a certain localized area or set of points. The beauty of slope field diagrams is that they can be drawn without actually solving the DE. Slope fields allow these people to view the probable trends of a certain population based on its conditioning factors without actually solving their DE's.

In differential equations you can find what is called a "general solution" even if no initial conditions are given. If you do have initial condition, then you can transform your general solution into a "particular solution".

With the slope field visualization, you saw Sal draw several particular solutions, each one dependent of the initial conditions that he choose

As the differential equation dy/dx is a function of y, plugging in the y-value 6 gives

dy/dx = 6/6 × (4-6) = 1 ×-2 = -2,

the slope you mentioned. If you look at the point (1, 6) on the slope field diagram, you can see a short downward sloping line, of approximately slope -2.

If the slope were pi at a point, you would see an upward sloping line of approximately 3.14159

We can solve for which points this would be at:

dy/dx = π = y/6 × (4-y)

π6 = 4y-y²

multiply both sides by 6, then distribute on the right

0 = -1*y² +4 × y - 6×π,

add 6×π to the right side

The quadratic should get the y-values where the slope is π

To find the displacement and total distance traveled by the object from t=0 to t=6, we need to integrate the velocity function over the given time interval.

The displacement can be found by integrating the velocity function v(t) with respect to t over the interval [0, 6]. The integral of v(t) represents the net change in position of the object during this time interval.

The total distance traveled can be determined by considering the absolute value of the velocity function over the interval [0, 6]. This accounts for both the forward and backward movements of the object.

Now, let's calculate the displacement and total distance traveled using the given velocity function v(t) = t^2 - (1/t) - 12 over the interval [0, 6].

To find the displacement, we integrate the velocity function as follows:

Displacement = ∫[0,6] (t^2 - (1/t) - 12) dt.

To find the total distance traveled, we integrate the absolute value of the velocity function as follows:

Total distance = ∫[0,6] |t^2 - (1/t) - 12| dt.

By evaluating these integrals, we can determine the displacement and total distance traveled by the object from t=0 to t=6.

To find the dot product of these two vectors, we use the formula:

u · v = (2 * -1) + (3 * 2) + (-1 * 0) = -2 + 6 + 0 = 4

The dot product of u and v is 4, which means that these two vectors are not orthogonal. A dot product of 0 would indicate that the vectors are orthogonal, meaning they are at 90 degrees to each other.

The dot product is a scalar value that represents the magnitude of one vector projected onto the other, and it's a measure of similarity between the vectors.

A positive dot product indicates that the vectors are pointing in a similar direction, while a negative dot product indicates that the vectors are pointing in opposite directions. A dot product of 0 means that the vectors are orthogonal, or perpendicular to each other.
