In statistics, the risk of making an error is referred to as a significance level. A significance level represents the probability of making a Type I error, which occurs when a null hypothesis is rejected even though it is true.

The most common significance level used in statistical analyses is 0.05 or 5%. This means that there is a 5% chance of rejecting a true null hypothesis.

In general, the choice of significance level depends on the specific application and context of the statistical analysis.

The 5% significance level is commonly used in scientific research, particularly in the fields of medicine and psychology.

The choice of this level is based on a balance between the risk of making a Type I error and the risk of making a Type II error, which occurs when a null hypothesis is not rejected even though it is false.

A Type II error is often more serious than a Type I error since it may lead to incorrect conclusions about the relationship between variables or the effectiveness of a treatment or intervention.

A 5% significance level provides a reasonable balance between these two types of errors. However, in some situations, a higher or lower significance level may be more appropriate.

For example, in a clinical trial where the consequences of a Type II error are severe, a lower significance level may be used to reduce the risk of this type of error.

Emily funded $6000 in stocks and $12,000 in bond funds. She also funded the remaining  $2,000 in her savings account.

Future value = $20,000

Simple interests rate = 1.5%

The return rate on bonds= 4.5%

The return rate on stocks = 6.2%

Total amount made on invests =  $942

Time period = 1 year

Let us assume that the amount of money Emily invested = x

Amount invested in stock = y

If the amount is twice = 2y

The interest earned = x * 0.015

Interest on bond = 2y * 0.045

Interest on stocks = y * 0.062

The equation will be:

(x * 0.015) + (2y * 0.045) + (y * 0.062) = 942

0.015x + 0.152y = 942  ------ Equation 1

Total future value is given as $20,000

x + 2y + y = 20000

x + 3y = 20000

x = 20000 - 3y

Substituting the x value in the first equation:

0.015(20000 - 3y) + 0.152y = 942

300 - 0.045y + 0.152y = 942

0.107y = 642

y = 6000

Therefore, we can conclude that Emily funded $6000 in stocks and $12,000 in bond funds.

Answer:

You distribute first 2 into the parentheses

2x-20 Is your answer

thats all you do

Step-by-step explanation:

You answered 6,9 and 10,13. The correct answer is 6,9 and 7,13 to find the equation of the linear model.

(a) The two points you selected are (6,9) and (10,13). This is correct.

(b) To find the slope of the linear model, we can use the formula: slope = (change in y) / (change in x). By using the points (6,9) and (10,13), we have (13-9) / (10-6) = 4/4 = 1. So, the slope is indeed 1. This is correct.

(c) The equation of the linear model in point-slope form is given as: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. Plugging in the values (6,9) as the point and 1 as the slope, we get y - 9 = 1(x - 6). This simplifies to y - 9 = x - 6. This is not the same as the equation you provided. It seems you made a mistake here.

(d) The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. To convert the equation y - 9 = x - 6 to slope-intercept form, we can add 9 to both sides: y = x - 6 + 9, which simplifies to y = x + 3. This matches the equation you provided. So, this is correct.

(e) The equation for the least squares regression line is in the form y = bx + a, where b is the slope and a is the y-intercept. In this case, the slope is 1, and we need to find the y-intercept.

We can use the point (6,9) and the slope-intercept form equation y = x + 3 to find the y-intercept: 9 = 6 + 3. Solving this equation, we find that the y-intercept is 3.

Therefore, the equation for the least squares regression line is y = x + 3. This does not match the equation you provided. It seems you made a mistake here.

(f) Based on the correct equation from part (d) (y = x + 3), the correct equation for the least squares regression line is y = 1x + 3. When rounded to three decimal places, this would be y = 1.000x + 3.000.

The equation you provided (Y = 1.028x + 2.271) is slightly different, so it appears you made a mistake in the calculations or rounding.

To summarize, your answers in parts (a) and (b) are correct. However, there are mistakes in parts (c), (e), and (f). The corrected answers are:

(c) The equation of the linear model in point-slope form: y - 9 = x - 6.

(d) The slope-intercept form of the equation: y = x + 3.

(e) The equation for the least squares regression line: y = 1x + 3.

(f) When rounded to three decimal places, the equation is: y = 1.000x + 3.000.

Answer:

Step-by-step explanation:

To find the number of ways that Mary, her three female friends, and her brother Peter can be seated in a row of 10 seats, we can follow these steps:

First, we need to consider the number of ways that the five people can sit together in the row of 10 seats. We can treat these five people as a single unit and arrange them in the row in 5! (5 factorial) ways.

However, since Mary and her friends are all female, we need to account for the number of ways that they can be arranged within this group of five. We can arrange the four women in 4! (4 factorial) ways.

Finally, we need to consider the number of ways that Peter can be seated in one of the remaining seats. Since there are six remaining seats, Peter can be seated in any of these seats in 6 ways.

Therefore, the total number of ways that Mary, her three female friends, and her brother Peter can be seated in the row of 10 seats is:

5! × 4! × 6 = 120 × 24 × 6 = 17,280

So there are 17,280 ways that these five people can be seated in the row of 10 seats, assuming that they all sit next to each other for the first half of the show.

The number is 546.208 in standard form.

Step-by-step explanation:

The standard form consist in the presentation of given number in decimal format. The proceeding is described as follows:

1) Each component of the sum is simplified.

2) Results are summed to get number in standard form.

That is,

Step 1

\(5 \times 100 = 500\)

\(4 \times 10 = 40\)

\(6 \times 1 = 6\)

\(2 \times \left(\frac{1}{10} \right) = 0.2\)

\(0 \times \left(\frac{1}{100}\right) = 0.00\)

\(8 \times \left(\frac{1}{1000} \right) = 0.008\)

Step 2

\(x = 500 + 40 + 6 + 0.2 + 0.00 + 0.008\)

\(x = 546.208\)

The number is 546.208 in standard form.

The number in standard form is written as 546.208

The length of FG is approximately 15.3 cm.

To calculate the length of FG using Pythagoras' theorem, we need to find the length of the hypotenuse (FG) of a right triangle. Let's denote the length of FG as x.

According to Pythagoras' theorem, in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, we have:

\(FG^2 = GH^2 + FH^2\)

Given that GH = 8 cm and FH = 13 cm, we can substitute these values into the equation:

\(x^2 = 8^2 + 13^2\)

\(x^2 = 64 + 169\)

\(x^2\) = 233

To find x, we take the square root of both sides:

x = √233 ≈ 15.26 cm (rounded to 1 decimal place)

Therefore, the length of FG is approximately 15.3 cm.

Answer:

5^125 ways

Step-by-step explanation:

We proceed as follows

Let us label the five printers as A,B,C,D and E

Each printer can print any number of pages since there are no restrictions

Therefore for every page to be printed , there are 5 printer options available

Page 1 = 5 options

Page 2 = 5 options and so on till page 125

So total number of ways to assign 125 pages to five printer = 5*5*5*......*5 (125times)

So total ways = 5^125 ways

Using the Fundamental Counting Theorem, it is found that there are \(5^{125}\) ways for the 125 pages to be assigned to the five printers.

Fundamental counting theorem:

States that if there are n things, each with  ways to be done, each thing independent of the other, the number of ways they can be done is:

\(N = n_1 \times n_2 \times \cdots \times n_n\)

In this problem:

\(N = n_1 \times n_2 \times \cdots \times n_{125}\)

5 is multiplied by itself 125 times, hence:

\(N = 5^{125}\)

There are \(5^{125}\) ways for the 125 pages to be assigned to the five printers.
