The margin of error is 2.326 for the supplied values of  c, σ, and n, which are 0.98, 0.78, and 150 respectively.

Margin is the term used to describe the equity that a trader has in their account. Using funds borrowed from a broker to buy stocks is referred to as "marging" or "buying on margin." Instead of a typical brokerage account, you must have a margin account to execute this. Beginning with your gross profit, which is the distinction between revenue and COGS, you may compute profit margin. Find the percentage of revenue that represents gross profit next. Calculate it by dividing your gross profit by your revenue. You can calculate your margin % by multiplying the sum by 100.

Given that,

Population standard deviation =  

 = 0.78

Sample size = n =150

α = 1 - 98% = 1 - 0.98 = 0.02

α= 2 = 0.02/ 2 = 0.01

Z*α = 2 = 0.01 = 2.326     (  Using z table    )  

Margin of error = E =  Z

Using the .01 level of significance means that, in the long run, a Type I error occurs 1 time in 100. This means that if we perform a statistical test 100 times, and we set the level of significance at .01, then we can expect to observe one false positive result due to chance alone. So, the correct option is 1).

A Type I error occurs when we reject a true null hypothesis, or when we conclude that there is a significant difference or relationship between two variables when in fact there is not.

By setting the level of significance at .01, we are minimizing the risk of making a Type I error while increasing the risk of making a Type II error, which occurs when we fail to reject a false null hypothesis. So, the correct answer is 1).

345,000 ; 350,00 ; 300,000.

Answer:

300,000

Step-by-step explanation:

the ten hundred thousands place would be

100,000

therefore the nearest ten hundred thousand would be

300,000

because the 345,047 isn't a high enough digit to be 5+ and make the nearest thousand 400,000 and not 300,000

If that doesn't help, think of it like this...

Anything before the place is what determines if the number will be higher or lower.

45 is lower than 50 and 50+ is the passing number to make the number 400,000.

Tip: when your rounding numbers the only numbers that stay the same and don't turn into 0's is like the 3 in "345,047" but the "45,047" part turns into 0's is because those aren't needed and because you rounded it, it's like it takes those numbers to make what you rounded to higher or lower.

so if you look at it like that the answer is 300,000.

Use the formula for finding the magnitude of a vector |u-v| = √((u1-v1)² + (u2-v2)² + (u3-v3)²).

To find |u-v|, we need to subtract vector v from vector u. Let's assume that vector u =  and vector v = .

The subtraction of vectors can be done by subtracting their corresponding components. So, |u-v| = ||.

Using the given vectors in Problem 3, substitute their values into the equation. Calculate the differences for each component.

Finally, use the formula for finding the magnitude of a vector:

|u-v| = √((u1-v1)² + (u2-v2)² + (u3-v3)²).

|u-v| = √((u1-v1)² + (u2-v2)²+ (u3-v3)²).
Substitute the values of u and v into the equation.

|u-v| is the square root of the sum of the squares of the differences between the corresponding components of u and v. |u-v| is equal to √3.

To find |u-v|, we need to calculate the magnitude of the difference between the vectors u and v.

Let's assume that u = (u1, u2, u3) and v = (v1, v2, v3) are the given vectors.

To find the difference between u and v, we subtract the corresponding components:

u - v = (u1 - v1, u2 - v2, u3 - v3)

Next, we calculate the magnitude of the difference vector using the formula:

|u-v| = √((u1 - v1)^2 + (u2 - v2)^2 + (u3 - v3)^2)

For example, if u = (2, 4, 6) and v = (1, 3, 5), we can find the difference:

u - v = (2 - 1, 4 - 3, 6 - 5) = (1, 1, 1)

Then, we calculate the magnitude:

|u-v| = √((1)^2 + (1)^2 + (1)^2) = √(1 + 1 + 1) = √3

Therefore, |u-v| is equal to √3.

The measure of angle L is given as follows:

<L = 33.9º.

First we obtain the measure of angle K, considering than an angle is supplementary with it's exterior angle, meaning that their sum is of 180, hence:

<K = 180 - 67.8

<K = 112.2º.

The sum of the measures of the internal angles of a triangle is of 180º, angle angles L and K are congruent, hence the measure of angle L is obtained as follows:

112.2 + 2L = 180

<L = (180 - 112.2)/2

<L = 33.9º.

Therefore the solution to this question is Anthony ran 5.5 miles each day after school.

An equation is a mathematical statement that proves the equality of two mathematical expressions, according to the definition of an equation in algebra. To give one example, the two expressions 3x + 5 and 14 are contained in the equation 3x + 5 = 14.

Here,

Let x represent how far he ran after school.

He ran four days straight after school, covering the same distance four times. He completed a 1.5-mile run before heading to school each day for a total of 6 miles. He completed 28 miles of running.

So, the equation which will represent this will be,

4(x + 1.5) = 284(x+1.5)=28

4x + 6 = 284x+6=28

4x = 28 - 64x=28−6

4x = 224x=22

x = 5.5x=5.5

So, Every day after school, Anthony ran 5.5 miles.

The percentage or the Probability is only 2.5%

Probability is a number that reflects the chance or likelihood that a particular event will occur. This is arrived based on the central limit theorem that sample mean follows a normal distribution for large samples randomly drawn.

Given that on the average, hotel guests who take elevators weigh about 150 pounds with an SD of about 35 pounds.

An engineer is designing a large elevator for a convention hotel, to lift 50 such people.

Maximum capacity = 4 tons =8000 pounds

= 160 pounds/man

If average of 50 people exceeds 160 pounds then it would be overloaded.

Mean of the sample follows a normal with mean = 150 and std error = 35/√50-1 = 5

Required probability

= P(x>160)

= P(Z ? 2)

= 0.0250

Probability is only 2.5%

This is arrived based on the central limit theorem that sample mean follows a normal distribution for large samples randomly drawn.

The solution involves an integral that cannot be evaluated in closed form, so the answer cannot be simplified further.

To solve the given differential equation (DE), we can use the integrating factor method. The steps are as follows:

1. Multiply both sides of the DE by the integrating factor, which is the exponential of the integral of the coefficient of y. In this case, the coefficient of y is (x + 2), so the integrating factor is e^(∫(x+2)dx) = e^(x^2/2 + 2x).

So, we have: (x + 1) e^(x^2/2 + 2x) dy/dx + (x + 2) e^(x^2/2 + 2x) y = 2x e^(x^2/2 + 2x) e^(-xy)

2. Notice that the left-hand side of the DE is the product of the derivative of y with respect to x and the integrating factor, so we can apply the product rule of differentiation to obtain:

d/dx [ e^(x^2/2 + 2x) y ] = 2x e^(x^2/2 + 2x) e^(-xy)

3. Integrate both sides of the previous equation with respect to x to obtain:

e^(x^2/2 + 2x) y = - e^(-xy) + C

where C is the constant of integration.

4. Solve for y by dividing both sides by the integrating factor:

y = [- e^(-xy) + C] e^(-x^2/2 - 2x)

This is the general solution of the given DE.

Note that the solution involves an integral that cannot be evaluated in closed form, so the answer cannot be simplified further.

Answer:

Step-by-step explanation:

The given data presents the marginal effects estimated from a probit model. Each row represents a variable, and the corresponding values show the marginal effect, standard error, z-statistic, and p-value. The marginal effect, represented as dF/dx, measures the change in the probability of the dependent variable (usually a binary outcome) resulting from a one-unit change in the independent variable.

In a probit model, the marginal effects provide insights into how changes in the independent variables affect the probability of the dependent variable. The estimated marginal effects indicate the direction and significance of these effects.

For example, a positive marginal effect indicates that an increase in the corresponding independent variable leads to a higher probability of the outcome occurring. Conversely, a negative marginal effect suggests a decrease in the probability. The standard error quantifies the uncertainty associated with the marginal effect estimate, and the z-statistic and p-value assess the statistical significance of the effect.

The significance codes provided (***, **, *, etc.) indicate the level of significance at which the null hypothesis (no effect) can be rejected. Lower p-values suggest higher significance. Researchers can use these results to understand the relative importance of different variables in influencing the probability of the outcome.

It's important to note that interpreting marginal effects requires considering the context of the model, the specific variables involved, and any assumptions made during estimation.
