How many different 8-letter permutations can be formed from 6 identical h's and two identical t's?.

When we are interested in deviations greater than or less than the hypothesized value, we do a two-sided test.

A two-tailed or two-sided test determines whether a sample is greater than or less than a specific range of values by using a two-sided critical area of distribution.

This test tests the null hypothesis. This test determines whether there is a statistically significant difference between the sample and population mean.

This test also determines whether a claim is true or not.

This test differs from a one-tailed test because one-tailed tests permit the potential for a one-directional effect. But the two-tailed tests examine the potential for two-directional (positive and negative directions) effects.

Matthew' curtain company will need 222 feet to make 74 curtains.

We will first convert the curtain length to feet. As per the known fact, 1 inch = 1/12 feet

So, 36 inch = 3 feet

Hence, each curtain will be of 3 feet length and hence requires 3 feet fabric.

So, the total amount of fabric required based on the need = 74 × 3

Performing multiplication on Right Hand Side of the equation

The total amount of fabric needed to make 74 curtains = 222 feet

Hence, the company will need 222 feet fabric to make 74 curtains.

If the ANOVA test is statistically significant, then we can determine which groups are different by means of the F statistic, which is defined by the ratio of the mean sum square to the average square error (none of the options are correct).

The ANOVA test can be defined as a strategy to assess when differences between two or even more groups and or populations in the same are statistically significant.

Moreover, the F statistic refers to the results of the ANOVA, which is used to show statistically significant differences between groups in the sample.

Therefore, with this data, we can see that the ANOVA test is used to determine when differences between groups in the sample are significant enough to explain a given working hypothesis, and it is associated with the F statistics.

Answer:

Step-by-step explanation:

Hailey so many people ask about this type of question.  I've got a cut and paste answer.   I would like to hear from you ,  posted in the comments of this problem.  what's the part of this type of problem that you find complex and difficult.  The math to do this is not hard.  But it is a difficult problem for so many people.  please write in your words what it is that you find difficult.  Thanks  :)

They ask for slope-intercept form of the problem.  this form:  y= mx + b

recall there is also point-slope form   of   y -y1 = m(x -x1)

They give us two points.  

point P1 (15,40)  in the form (x1,y1)

point P2(41,61)  in the form (x2,y2)

Step1:  find the slope

slope = m

m = (y2-y1) / (x2-x1)

m= (61-40) / (41-15)

m = 19 / 26

Step 2: now use the point-slope form to get the slope-intercept form. Any given point will work, I'll use P1

y - y1 = m(x -x1)

y - 40 = [tex]\frac{19}{26}[/tex](X - 15 )

use  your algebra skillz to solve for "Y" ( get "Y" by itself )

y - 40  =   [tex]\frac{19}{26}[/tex]X -  [tex]\frac{19}{26}[/tex]*15

y - 40 = [tex]\frac{19}{26}[/tex]X - [tex]\frac{285}{26}[/tex]

y - 40 =  [tex]\frac{19}{26}[/tex]X - 10[tex]\frac{25}{26}[/tex]

Y =  [tex]\frac{19}{26}[/tex]X - 10[tex]\frac{25}{26}[/tex] + 40

Y =  [tex]\frac{19}{26}[/tex]X + 30[tex]\frac{25}{26}[/tex]    this is in slope-intercept form now

There will be 5.41667 gallons of water in the bucket after 1 second according to the straight line present in graph.

The line passes through O(0, 0) and A(12, 5).

The slope of the line OA is given by :

Slope, m = ([tex]y_{2} - y_{1}[/tex])/([tex]x_{2} - x_{1}[/tex])

⇒ m = (5 - 0)/(12 - 0)

⇒ m = 5/12

The equation of the line passing through (0, 0) having slope = 5/12 is :

(y - 0) = (5/12)(x - 0)

⇒ y = 5x/12

After 1 second, the time t = 13 sec

Then, on substituting x = 13 in y = 5x/12, we can get the no. of gallons of water :

⇒ y = 5(13)/12 = 65/12 = 5.41667

Hence, after 1 second there will be 5.41667 gallons of water in the bucket.

Step-by-step explanation:

For a Regression Analysis that the value of R is 0.42, the value of the Coefficient of Non-Determination is 0.8236.

Coefficient of non-determination is the variation recorded in the dependent variable which is not counted by the changes in the explanatory variable. This is calculated by subtracting Coefficient of Determination from 1.

Coefficient of Non-Determination explains the amount of unexplained, or unaccounted for, variance among two variables, or among a set of variables (predictors) in an outcome variable.

The formula for the Coefficient of Non-Determination is 1 – R².

So, in this case:

1 – R²

= 1 – (0.42)²

= 1 – 0.1764

= 0.8236

Hence, the value of the Coefficient of Non-Determination is 0.8236.

The lines p and q are perpendicular lines.

According to the question,

We have the following information:

Line p passes through points (18, 11) and (-17, 22). Line q passes through points (2, 37) and (-9, 72).

We will find the slope of both the lines to check whether they are perpendicular or parallel. If their slope is equal then they are parallel and if their slope is not equal or inverse of the other one then they are perpendicular.

(Slope is denoted by m.)

m = (y2-y1)/(x2-x1)

For line p:

x1 = 18, y1 = 11, x2 = -17 and y2 = 22

m = (22-11)/(-17-18)

m = -11/35

For line q:

x1 = 2, y1 = 37, x2 = -9 and y2 = 72

m = (72-37)/(-9-2)

m = -35/11

Now, the slope is inverse.

The solution to the equation by linear combination is (d) (3, 5)

From the question, we have the following system of equations

2x – 3y = – 9

x + 3y = 18

By linear combination, we start by eliminating one of the variables

This is done by adding the equations

So, we have

2x + x -3y + 3y = -9 + 18

Evaluate the like terms

3x = 9

Divide both sides

x = 3

Substitute x = 3 in x + 3y = 18

3 + 3y = 18

So, we have

3y = 15

Main answer:

She bought 5 coach tickets and 6 first class tickets.

Step-by-step explanation:

Given:

Total tickets = 11

Let's First class tickets =f, Coach tickets = c.

Total tickets = f + c

     f + c = 11  

⇒  f = 11 - c  →   equation 1

Cost she used to purchase coach tickets = $260

Cost she used to purchase First class tickets = $1130

Total budget for airfare = $8080

260c + 1130f = 8080  →  equation 2

Substitute equation 1 in equation 2;

260c + 1130(11-c) = 8080

260c + 12430 - 1130c = 8080

12430 - 8080 = 1130c- 260c

870c = 4350

c = 5 peoples

Now, Substitute c in equation 1;

f + c = 11

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 115 grams of a radioactive isotope

If we start with 115g of the isotope, after one half-life the quantity will diminish to [tex]\frac{115g}{2} = 57.5[/tex] which is half the original quantity.

This can be written mathematically as: [tex]115g(\frac{1}{2})^{1}[/tex]

After the second half life: [tex]\frac{57.5g}{2} = 28.75 = \frac{115g}{4} = (115g)\frac{1}{2}^{2}[/tex]

After the third half life: [tex]\frac{28.75g}{2} = 14.37g = \frac{115g}{8} = (115g)(\frac{1}{2}) ^{3}[/tex]

But now we can see a pattern developing, because for each new half-life we are dividing the quantity by 2 to a power that increases as the number of half-lives.

Then we can take the original quantity and quickly compute for 6 half-lives:

[tex](115g)(\frac{1}{2})^{6} = (115g)(\frac{1}{64}) = \frac{115g}{64} = 1.79g[/tex]
