1. John is currently watching 9 different television shows.

a) If John watches one episode of each of these shows, how many orders of shows can he watch?

b) If John wants to download 5 random episodes of these 9 shows, how many combinations exist? (He only downloads 1 episode from any given show.)

c) Out of a group of 12 students competing on the Gymnastics team, how many different ways can a captain, equipment manager, and sound manager be selected at random if no person can hold two positions

The total money made by each court would be as follows:

Centre Court: £838,824, No 1 Court: £514,305

No 2 Court: £164,000, No 3 Court: £82,000

To calculate the amount of money made by each court if all seats were sold, we need to multiply the number of seats by the corresponding ticket price for each court. Here are the calculations for each court:

Centre Court:

Number of seats: 14,979

Ticket price: £56

Total money made: 14,979 seats ×£56/seat = £838,824

No 1 Court:

Number of seats: 11,429

Ticket price: £45

Total money made: 11,429 seats ×£45/seat = £514,305

No 2 Court:

Number of seats: 4,000

Ticket price: £41

Total money made: 4,000 seats ×£41/seat = £164,000

No 3 Court:

Number of seats: 2,000

Ticket price: £41

Total money made: 2,000 seats × £41/seat = £82,000

Therefore, if all seats were sold, the total money made by each court would be as follows:

Centre Court: £838,824

No 1 Court: £514,305

No 2 Court: £164,000

No 3 Court: £82,000

Answer:

-x² + 6x - 17

Step-by-step explanation:

First, expand (x-3)² using FOIL

(x - 3)(x - 3)

= x² - 6x + 9

Distribute the negative sign to the expression:

-(x² - 6x + 9)

-x² + 6x - 9

Now, subtract 8 from this

-x² + 6x - 9

= -x² + 6x - 17

So, the equation in standard form is -x² + 6x - 17

The answer is.. x^2+6x-17

Let's start solving the given problem. Suppose that an urn contains 3 different types of balls: red, green, and blue. Let pi denote the proportion of red balls, p2 denote the proportion of green balls, and p3 denote the proportion of blue balls.

Here Pi = 1.

Suppose also that 100 balls are selected with replacement, and there are exactly 38 red, 29 green and 33 blue.

We need to find the M.L.E. p; of p1, i = 1, 2, 3.

The probability of obtaining red ball from the urn = pi. The probability of obtaining green ball from the urn = p2. The probability of obtaining blue ball from the urn = p3

Given that, 100 balls are selected with replacement.

Let's calculate the probability of getting 38 red, 29 green, and 33 blue balls from the urn,

P(38 Red and 29 Green and 33 Blue) = P(Red)38 x P(Green)29 x P(Blue)33 = p₁³⁸ x p₂²⁹ x p₃³³

Therefore, the likelihood of obtaining the 38 red, 29 green, and 33 blue balls is L(p1,p2,p3) = p₁³⁸ x p₂²⁹ x p₃³³

Since, L(p1,p2,p3) is a continuous function, so we have to find the critical points of the function to obtain the minimum value of p₁. Let's take natural logarithm on both sides of the function, we get ln

L(p1,p2,p3) = 38 ln p₁ + 29 ln p₂ + 33 ln p₃.

So, taking partial differentiation with respect to p1, p2 and p3 and equating them to 0. We get the following equations,∂ ln L / ∂p1 = 38/p1 = 0∂ ln L / ∂p2 = 29/p2 = 0∂ ln L / ∂p3 = 33/p3 = 0On

solving the above three equations, we get p1 = 38/100 = 0.38p2 = 29/100 = 0.29p3 = 33/100 = 0.33

Therefore, P₁= 0.38, S= 0.29, P3 = 0.33. Hence, the required solution is P₁= 0.38, S= 0.29, P3 = 0.33.

Answer:

[tex]-4a + 12[/tex]

Step-by-step explanation:

Y Let f:R → R be defined by f(3) = Then x2 +1' a is (b) f is not a measurable function.

To determine if f is a measurable function, we need to check if the preimage of any measurable set in the codomain (R) is a measurable set in the domain (R).

In this case, the function f(3) = x^2 + 1 is defined only at x = 3. Since the domain R is continuous and f is only defined at a single point, the preimage of any set in the codomain will either be an empty set or a singleton set containing only the point x = 3.

For example, consider the set [f > 3] in the codomain R. The preimage of [f > 3] under f would be the set of all x in the domain R such that f(x) > 3. However, since f is only defined at x = 3, the preimage would be the singleton set {3}.  Since {3} is not a measurable set in the domain R, f is not a measurable function.

Therefore , the correct option is (B) f is not a measurable function.

A possible set of scores for the students is: 4, 4, 6, 6, 6

We are given that five students took the quiz. If the lowest score is 4 and the highest score is 6, we can say that the set of values ​​can be expressed as:

4, x, y, z, 6

Here we can see that the mode is 6 and the mean is 5.2. Therefore, at least one other student of hers has scored her 6, which could result in:

4, x, y, 6, 6

Therefore:

(4 + x + y + 6 + 6)/5 = 5.2

16+x+y=26

x + y = 10

So the other two numbers are probably 6 and 4, because 6 is the mode, so they can't both be 5.

Step-by-step explanation:

Let the number of dogs Ma Bernier have be represented with d

She has 3 times as many cats as dogs, the number of cats she has :

cats = 3d

The sum of the cats and dogs is 52

d + 3d = 52

4d = 52

divide both sides of the equation by 4

d = 13

She has 13 dogs

Cats = 3d

Step-by-step explanation:

The linear system X₁ + 2X₂ = 3.21 and 4.02X₁ + IL || -1 = -1 using Cramer's rule, we need to find the values of X₁ and X₂.

To apply Cramer's rule, we first need to calculate the determinant of the coefficient matrix and the determinants of the matrices obtained by replacing each column of the coefficient matrix with the constant terms.

The coefficient matrix is:

| 1   2 |

| 4.02  IL || |

The determinant of the coefficient matrix, denoted as D, is given by:

D = (1 * IL ||) - (2 * 4.02)

  = IL || - 8.04

The matrix obtained by replacing the first column with the constant terms is:

| 3.21   2 |

| -1     IL || |

The determinant of this matrix, denoted as D₁, is given by:

D₁ = (3.21 * IL ||) - (-1 * 2)

   = 3.21IL || + 2

The matrix obtained by replacing the second column with the constant terms is:

| 1   3.21 |

| 4.02  -1 |

The determinant of this matrix, denoted as D₂, is given by:

D₂ = (1 * -1) - (4.02 * 3.21)

   = -1 - 12.9042

   = -13.9042

Now, we can find the values of X₁ and X₂ using the formulas:

X₁ = D₁ / D

X₂ = D₂ / D

Substituting the values we calculated earlier, we have:

X₁ = (3.21IL || + 2) / (IL || - 8.04)

X₂ = (-13.9042) / (IL || - 8.04)

This gives us the solution to the linear system.

Solve the linear system X 1 X1 + 2x2 3.21 + 4.02 IL || -1 -1 = via Cramer's rule if possible.

A. The volume of the solid formed by rotating the region bounded above by the parabola y = 3x-x² and y = 0 around the vertical line x = -1 is approximately 9.74 cubic units and B. The inverse function is found to be ln(x/(1 - x)).

To find the volume of the solid, we can use the method of cylindrical shells. The integral for the volume is given by V = ∫[a,b] 2πxf(x) dx, where f(x) represents the height of the shell at each x-coordinate.

First, we need to find the bounds of integration. The parabola y = 3x - x² intersects the x-axis at x = 0 and x = 3. Therefore, the bounds of integration are [0, 3].

Next, we need to express the height of the shell, f(x), in terms of x.

Evaluating the integral, we get V = ∫[0,3] 2π(x + 1)(3x - x²) dx. After integrating and simplifying, the volume is approximately 9.74 cubic units.

(B) To find the inverse of the function f(x), we swap the roles of x and y and solve for y. So, we start with y = eˣ/(1 - eˣ).

Step 1: Swap x and y: x = eʸ/(1 - eʸ).

Step 2: Solve for y: x(1 - eʸ) = eʸ.

Step 3: Expand and isolate eʸ: x - xeʸ = eʸ.

Step 4: Factor out eʸ: eʸ(x - 1) = x.

Step 5: Divide both sides by (x - 1): eʸ = x/(x - 1).

Step 6: Take the natural logarithm of both sides: y = ln(x/(x - 1)). Thus, the inverse function is g(x) = ln(x/(x - 1)), where x ∈ (0, 1).
