you suspect that an unscrupullous employee at a casino has tampereed with a die. that is, he is using a loaded die. In order to test this claim you roll it 258 times and obtain the folllowing frquencies Category 1 2 3 4 5 6 Frequency 48 52 51 34 48 25 a. Choose the approp. alternative hypotheses to test if the population proportion differ a/all population proportion differ from 1/6 b/ Not ll population proportion are equal to 1/6 b-1 calculate the value of the test statistic(round to at last 4 decimal places) b-2 Approx. the p-value c. at the 10% signifigance level. can you conclude that the die is loaded?

Answers

a. For the alternative hypothesis, you normally would want to choose something that says not equal since you will need to be testing if the proportions are equal and this will be your null hypothesis.

Therefore for your alternative hypothesis it would need to be: Not all population proportions are equal to 1/6.

b-1. Since we have 6 different outcomes, we will use the chi square test to evaluate the hypothesis. The test statistic is computed by getting the summation of [tex] \frac{ (observed-expected)^{2} }{expected} [/tex] for all the 6 outcomes. In our case the expected proportion would be 1/6 or 0.1667 and the observed values would be the proportions from the 6 outcomes.

[tex] X^{2} = \frac{ (0.1860-0.1667)^{2} }{0.1667} +\frac{ (0.2016-0.1667)^{2} }{0.1667}+\frac{ (0.1977-0.1667)^{2} }{0.1667}[/tex]
[tex]+\frac{ (0.1318-0.1667)^{2} }{0.1667}+\frac{ (0.1860-0.1667)^{2} }{0.1667}+\frac{ (0.0969-0.1667)^{2} }{0.1667}=0.0541[/tex]

ANSWER: The test statistic is 0.0541

b-2. For this problem we just imagine the chi square distribution and the fact that our test statistic is so close to zero so the p-value must be so much greater than 0.10.

Based on other resources, there are choices to this problem so we just choose the option similar to the one we just described.

ANSWER: p-value > 0.10

c. Since the p-value we estimated above is greater than 0.10, we do not reject the null hypothesis. This means that there is NOT enough evidence to reject the fact that the die is a fair die.

ANSWER: No, we cannot conclude that the die is loaded.

Maggie and her friend visit a beach that has a shoreline 2 2/5 kilometers long. They walk along 2/3 of it. How many kilometers of the beach shoreline do they walk?

Answers

Simply put, this question is asking "What is 2/3 of 2 2/5 ?". 

If we want to find 2/3 of 2 2/5, we can multiply the fractions together. 

[tex] \frac{2}{3} * 2 \frac{2}{5} [/tex]

= [tex] \frac{24}{15} [/tex]

= [tex] \frac{8}{5} [/tex]

= [tex]1 \frac{3}{5} [/tex]

This means that Maggie and her friend have walked [tex] 1 \frac{3}{5} [/tex] kilometers of the beach shoreline. 
Final answer:

To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along. Maggie and her friend walk 8/5 kilometers of the beach shoreline.

Explanation:

To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along.

First, we need to convert the mixed number 2 2/5 to an improper fraction. We can do this by multiplying the whole number (2) by the denominator (5) and adding the result to the numerator (2), then putting the new numerator over the denominator. So, 2 2/5 is equal to (2 * 5 + 2) / 5 = 12/5.

Next, we can multiply the length of the shoreline (2 2/5) by the fraction they walk along (2/3). Multiply the whole number and numerator separately, then add the products and put the result over the denominator.

So, (12/5) * (2/3) = (12 * 2) / (5 * 3) = 24/15 = 8/5.

Maggie and her friend walk 8/5 kilometers of the beach shoreline.

Hello there! I can help you! The surface area is where you add the areas of the shapes to find the area of the surface. 15 is the side of the square. We can raise 15 to the second power (15²) to get 225. The total surface area is 945 square feet. Let's subtract 225. 945 - 225 is 720. There are 4 triangles. 720 square feet is the sum of the surface area of 4 triangles so let's divde 720 by 4 to find the area of each triangle. 720/4 is 180. The area of each triangle is 180. But we're not done. We need to look for the height. The formula for the area of the triangle is 1/2 the product of base and height. (½bh) When we divide by 2, our answer should be 180. So the product of the two numbers should be 360. We know that the base is 15ft long, so let's divide. 360/15 is 24. 15 * 24 is 360. 360/2 is 180. There. The height of each triangular base is 24 ft.

Answers

The answer is a parallelogram.  Quadrilateral have 4 sides, and if there are not right angles, it cannot be a rectangle because that is the added characteristic of rectangles.  All rectangles are actually parallelograms, but only parallelograms will have exactly 2 pairs of parallel sides with no right angles.  The statement says "may" because as I mentioned before, rectangles are parallelograms too!

What is the average weight of the kittens in the shelter?

Answers

You should add the weights of each kitten and then divide by the number of kittens. Ex. There are 5 kittens weighing 2, 1, 3, 2, and 2. So you would add those to get 10 and divide by the number of kittens which is 5 to get an average of 2.

Average weight of the kitten in the shelter = Total weight of the kittens / Number of kittens.

What is Average?

An average is a single number taken as representative of a list of numbers, usually the sum of the numbers divided by how many numbers are in the list.

Here,

Average weight of the kittens in the shelter = Total weight of all kitten/ Number of kittens.

Hence, the average weight of the kitten in the shelter = Total weight of all kitten/ Number of kittens.

The first pentagon is dilated to form the second pentagon. Drag and drop the answer to correctly complete the statement. The scale factor is . A pentagon with a side length of 4. An arrow points to a larger pentagon with a side length of 5

Answers

To find the scale factor, we want to find the number that we would multiply 4 by to get 5.  This gives us the equation 4x = 5.  Solve by dividing both sides by 4:
4x/4 = 5/4
x = 1.25
The scale factor is 1.25. 

Final answer:

To find the scale factor for the dilation of a pentagon from a side length of 4 to a side length of 5, divide the new dimension by the original dimension, resulting in a scale factor of 1.25.

Explanation:

The question asks about finding the scale factor used to dilate a pentagon from a side length of 4 to a side length of 5. To find the scale factor, we compare the new dimension to the original dimension. In this case, the side length of the second pentagon is 5, and the side length of the first pentagon is 4. To find the scale factor, we divide the new dimension by the original dimension, which is 5/4. Hence, the scale factor is 1.25.

To clarify, the scale factor is determined by dividing the new dimension (5) by the original dimension (4), yielding 5/4. Therefore, the scale factor is indeed 1.25. This indicates that each side of the pentagon has been multiplied by 1.25 to achieve the dilation from a side length of 4 to a side length of 5.

Formulate a system of equations to represent this situation, with f = the amount of money that Frank spent and r = the amount of money that Rachel spent. Frank and Rachel spent a total of $15.75. If Rachel spends twice as much money as Frank, how much money did they each spend?
A)
B)
C)
D)

Answers

Rachel and Frank spends $10.5 and $5.25 respectively.

It is given to us that

f is the amount of money that Frank spent and

r is the amount of money that Rachel spent.

Frank and Rachel together spent a total of $15.75.

Rachel spends twice as compare to Frank

The equation that represents this situation:

1. f + r = $15.75

2. r = 2f

Substituting r = 2f in equation 1.

f + r = 15.75

f + 2f = 15.75

3f = 15.75

f = 5.25

Substituting f = 5.25 in equation 2.

r = 2f

r = 2(5.25)

r = 10.5

Thus, Rachel spends $10.5 and Frank spends $5.25.

Answers

You need to convert the sequence to a formula 

Since step 1 is 63,360 and each is 6 higher. 

First I will try... 

Altitude = 63,360 + 6x 

Lets check it with step 1 ... 

= 63,360 + 6(1) 
= 63,366 
wrong. 

6 too high 

So the formula would be 

Altitude = 6x + 63,354 

Lets test for known step 5 which the sequence says will be 63,384 ... 

= 6(5) + 63,354 
= 30 + 63,354 
= 63,384 

Looks good ! 

Now... 

For step 55 just plug in 55 as X to solve. 

= 6(55) + 63,354

What is the interquartile range of the data set? Enter the answer in the box. Key: 1|5 means 15

Answers

First of all we have to arrange the data in ascending order as shown below:

28, 40, 43, 43, 45, 50, 50

Total number of values = 7

Since the number of values is odd, the median will be the middle value i.e. 4th value which is 43. Median divides the data in two halves:

1st Half = 28, 40, 43
2nd Half = 45, 50, 50

Q1 or the First Quartile is the middle value of the lower or 1st half which is 40.
Q3 or the Third Quartile is the middle value of the upper or second half, which is 50.

IQR or the Inter Quartile Range is the difference of Q3 and Q1.

So, IQR= Q3 – Q1 = 50 – 40 = 10

Thus, IQR for the given data is 10
Answer:

The interquartile range(IQR) of the data set is:

                               10

Step-by-step explanation:

The data points according to the stem and leaf plot are as follows:

           28    40    43    43    45   50    50

We know that the median of the data is the central tendency of the data and always lie in the middle of the data.

Here looking at the data we have:

Median= 43

Similarly the lower set of data is:

                    28    40    43

Hence, the first quartile or the lower quartile i.e. [tex]Q_1[/tex] is the median of the lower set of data.

Hence,

[tex]Q_1=40[/tex]

Similarly, the upper set of data is:

                 45   50   50

Hence, the upper quartile or the third quartile i.e. [tex]Q_3[/tex] is the median of the upper set of data.

Hence,

[tex]Q_3=50[/tex]

The interquartile range(IQR) is calculated as:

[tex]IQR=Q_3-Q_1\\\\IQR=50-40\\\\IQR=10[/tex]

If you take a certain number 2.5 times then add 1.75 and divide the result by 0.8, you’ll get 37.5. What was the original number?

Answers

Answer:

The original number is 11.3

Step-by-step explanation:

Let the number is x and then we form the equation to solve it for the value of x.

1- Number is multiplied by 2.5 then it becomes = 2.5x

2- Then we add 1.75 to the expression then new expression will be = 2.5x + 1.75

3- We divide the result by 0.8 then expression will be = [tex]\frac{2.5x + 1.75}{0.8}[/tex]

4- Now the final expression is equal to 37.5 so the equation will be

[tex]\frac{2.5x + 1.75}{0.8}[/tex] = 37.5

Now we multiply 0.8 in both the sides of the equation

[tex]\frac{2.5x + 1.75}{0.8}[/tex]×0.8 = 37.5×0.8

2.5x + 1.75 = 30

2.5x = 30 - 1.75

2.5x = 28.25

x = 28.25/2.5 = 11.3
