The probability that when n=6,  \(Y_{1}\) =3, \(Y_{2}\)=1, \(Y_{2}\)=2 is 0.0822.

We have to find the probability that n=6,  \(Y_{1}\) =3, \(Y_{2}\)=1, \(Y_{2}\)=2

A rat has three possible exits to come out from the maze

The pmf of multinomial distribution is

P\((y_{1}, y_{2}, y_{3}......, y_{k} ) = \frac{n!}{{y_{1!} }y_{2}!....y_{k}! } p^y_1 1p^y_2 2......p^y_k k\)

The probability of choosing one of the ways is 1/3

Then \(p_{1}\)= 1 / 3,\(q_{1}\) = 1-(1/3) = 2/3

        \(p_{2} = 1/3, q_{2} = 2/3\\ p_{3} = 1/3, q_{3} = 2/3\)

\(P(y_{1}, y_{2}, y_{3} ) = P(1,2,3)\\ = \frac{6!}{3! 2! 1!} (\frac{1}{3} )3(\frac{1}{3} )2(\frac{1}{3} )1\)

                      =60(0.00137)

                      =0.0822

Hence, the probability that when n=6,  \(Y_{1}\) =3, \(Y_{2}\)=1, \(Y_{2}\)=2 is 0.0822.

$15 is the cost of a 6-ounce serving cost.

What is the cost price?

The precise value that corresponds to the unit price paid is represented by the cost price. In some stock market theories, this value is utilized to establish the value of stock holdings and is used as a key determinant of profitability.

Here, we have

Given: If a 24-pound EP rib of beef costing $45.00 is purchased oven-ready, and 1/4 of it is lost during roasting.

EP = 24 lb costing $45

1/4th lost during roasting.

Remaining = 24 lb - (1/4) of 24 lb

= 24 lb - 6 lb

= 18 lb

Now, this roast should match the cost of the original EP.

Cost per lb = (cost of beef originally)/(quantity of roasted beef)

= 45/18 dollar per lb

Cost of 6-ounce serving cost = (45/18)×6 = $15.

Hence, $15 is the cost of a 6-ounce serving cost.

Answer:

(a.) max height = 5.16 ft at 0.5 seconds

(b.) 4.91 ft

(c.) max height = 5.16 ft

(d.) height at 2 seconds = 2.91 ft

Step-by-step explanation:

(a.) The maximum height is also known as the vertex.

We can find it by using the formula

\(x =\frac{-b}{2a}\), which gives us the x coordinate of the vertex (or in this case, the time at which the rocket reaches its maximum height).

Then, we can plug this value in the quadratic equation to find the y coordinate of the vertex (i.e., the maximum height the rocket reaches.

The equation is currently in the standard form, which is:

\(y = ax^2+bx + c\).

Thus, our a is -1 and b is 1:

\(x=\frac{-1}{2(-1)}=\frac{1}{2}=0.5 \\\\y=-(0.5)^2+0.5+4.91\\y=-0.25+0.5+4.91\\y=0.25+4.91\\y=5.16\)

Thus, the max height is 5.16 ft and the rocket reaches it at 0.5 seconds.

(b). As mentioned in the explanation for part a, the equation is currently in standard form and c is the constant or y-intercept. Thus, the initial height is 4.91 ft

(c.) We found that the maximum height of the rocket is 5.16 ft.

(d.) We simply plug in 2 for x in the equation to find h:

\(h(2)=-(2)^2+2+4.91\\h(2)=-4+2+4.91\\h(2)=-2+4.91\\h(2)=2.91\)

As shown, the height of the rocket at 2 seconds is 2.91 ft.

Answer:

Type II error.

Step-by-step explanation:

We have a hypothesis test for the claim that placing a seasonal cookie product on an end cap (the shelf at the end of an aisle at a store) will make a difference in sales.

The null hypothesis will state that there is no difference, while the alternative hypothesis will state that there is significant positive difference.

The result is a P-value of 0.1288 and the null hypothesis failing to be rejected.

As the null hypothesis failed to be rejected, if an error has been made in the conclusion, is that we erroneusly accept a false null hypothesis.

This is a Type II error, where the null hypothesis is accepted although the alternative hypothesis is true.

Step-by-step explanation:

After decreasing new value would be : 100%  - 13% = 87%

87 % = 87/100 = 0.87

The percentage of the data values are between 110 and 170 = 37.5%

We know that in the box plot, the first quartile is nothing but 25% from smallest to largest of data values.

The second quartile is nothing but between 25.1% and 50% (i.e., till median)

The third quartile: 51% to 75% (above the median)

And the fourth quartile: 25% of largest numbers.

In the attached box plot, we can observe that between two numbers on the number line there are 5 equal parts.

So, each unit length measures 10 units.

Also, the median of the data = 110

We need to find the percentage of the data values are between 110 and 170.

i.e., the percentage of the data values are in the third quartile.

The range of this box plot is: 190 - 30 = 160

The data values are between 110 and 170 = 60

Using percentage formula,

P = (60/160) × 100

P = 37.5%

Answer:

The C=intercept of the regression line

Step-by-step explanation:

The slope of the regression line has a logical interpretation as the average rate of change in collar size for a 1cm increase in height.

A linear regression is represented as \(^\wedge y = mx + c\)

The option that has no logical interpretation is: E The c-intercept of the regression line

From the question, we have:

\(^\wedge c = 94 + 0.9h\)

Using the above representation of a regression line \(\wedge y = mx + c\)

\(m \to\) the slope

\(c \to\) the y-intercept

By comparing \(\wedge y = mx + c\) to  \(^\wedge c = 94 + 0.9h\)

\(0.9 \to\) slope

\(94 \to\) the y-intercept

While \(^ \wedge c\) and \(h\) are the variables (i.e. collar size and height)

From the list of given options (see attachment), the option that has no logical interpretation is:

Because the positions of the respective vertices did not change, we can see that there was a translation.

We can see two figures in a coordinate axis, one is on the right side and the other is on the left side.

We can see that the left figure is larger than the right one, so there was some kind of dilation here.

Now, assume that we had a reflection over the y-axis, then the position of the vertices in the left side should be inverted.

Because the positions of the vertices D' and B' are in the same sides in both figures, we conclude that there was a translation applied.

1. Convert fraction into same decimal.

To find this answer, we want to first convert the fraction so that the denominators are the same:

3/4 = ?/8

Divide the original denominator by the needed-to-be denominator.

8 / 4 = 2

Do reversal calculations

4 x 2 = 8

So, now that we know to multiply the original denominator by 2 to get the new denominator, multiple the numeriator by the same.

3           6

_  x 2 = _

4           8

So now, the new equation is:

How many 1/8 teaspoons are equal to 4 6/8 teaspoons.

(The reason why you must convert is because then you can simply say that the fraction is 6 1/8's, which means you just have to worry about the whole numbers.

2. Convert the whole numbers into a fraction to make it easier.

In order to convert whole numbers into fractions, first find the denominator your using. Which in this case, it is 8.

?/8

Now remember, for it to be a whole number, the numeriator and denominator MUST be the same.

8/8 = 1

Now remember, there are four 1's. Multiply the numeriator by 4, but keep the denominator the same or else the equation is ruined.

32/8 = 4

3. Add all your information together.

DO NOT forget to add the information you collected during the equation, or else you will get a wrong answer. Add the equation's final answer to the whole numbers final answer.

32 / 8 + 6 / 8 = ?

32 / 8 + 6 / 8 = 38 / 8

Well now, remember something. It is asking us, how many 1/8's were in the equation 4 3/4. We have transformed 4 3/4 into a whole equation, 38/8.

Now, all you need to do is look at the numeriator.

What number do you see?

You see 38.

The denominator is the correct denominator that you need. So, the number of the numeriator is the answer to the equation.

So, how many 1/8 are in 38/8?

Now to find out how many ⅛ teaspoons will equal 19/4 teaspoons, all we need to do is to divide 19/4 by ⅛

Thus;

19/4 ÷ 1/8
