Answer:

A. (Table Attached)

B. (See Step 3)

C. 0.06 (See Step 4)

D. NOT independent (See Step 5)

Step-by-step explanation:

Name the probabilities:

p₁ = 0.02,   p₂ = 0.07,   p₃ = 0.91

q₁ = 1-p₁ = 0.98 ,   q₂ = 1-p₂ = 0.93 ,   q₃ = 0.09

Let X and Y be the number of bits with high and moderate distortion out of three.

A.

The function will follow multinomial distribution:

\(f_{XY}(x,y) = P(X=x, Y=y) = \frac{3!}{x!y!(3-x-y)!} (p_1^x)(p_2^y)(p_3^{3-x-y})\)

Substitute the values and make a table.

TABLE IN ATTACHMENT

B.

We calculate marginal distribution by:

\(P (X=x)=\) ∑ \(P(X=x,Y=y)\)

\(fx(x)\) can be found by adding all the probabilities in each row for different value of X

For X=0 , ∑P = 0.94157441

For X=1 , ∑P = 0.057624

For X=2 , ∑P = 0.001176

For X=3 , ∑P =0.000008

The mathematic expectation E is the sum of product of each possibility with its probabiity.

\(E(X)=\)∑ \(xP(X=x)\)

Find E(X):

\(E(X)= (0*0.9415744)+(1*0.057624)+(2*0.001176)+(3*0.000008)\)

\(E(X)=0.06\)

Condition probability states:

\(P(A|B)=\frac{P(A,B)}{P(B)}\)

It can also be written as:

\(f_{Y|X=1}(y)=\frac{f_{XY}(1,y)}{f_x(1)}\)

Where \(f_x(1)\\\) = 0.057624

Calculate the quotient:

\(Y|_{x=1}\) = 0 ,  \(f_{Y|_X=1\) = 0.862245

\(Y|_{x=1}\) = 1 ,  \(f_{Y|_X=1\) = 0.132653

\(Y|_{x=1}\) = 2 ,  \(f_{Y|_X=1\) = 0.000510

\(Y|_{x=1}\) = 3 ,  \(f_{Y|_X=1\) = 0

Find the dependency:

\(f_{XY}(y)=f_X(x)f_Y(y)\)

We found that

\(f_{Y|_X=1\) = 0.862245

Calculate \(f_Y(1)\) from summing the column from the table

\(f_Y(1)=0.17428341+0.007644+0.000084\\f_Y(1)=0.18201141\)

Which are not equal.

Conclusion:

X and Y are NOT Independent

It is necessary to compute in the volume of the rotated region while taking into account that each cross section piece is raised up by a height of h = 4 - y. Scale the results by 62.4 lb/ft3 as well.

The given parabolic region's volume of revolution about the y-axis is a parabolic cylinder. This solid is revolved, and it has circular disks as its cross section. The differential volume of one such disk situated at a differential height y above the x-axis must be determined. The weight of water in this volume can then be calculated by multiplying this volume by the density of water. The depth of this volume is then determined from the tank's top surface. Determine how much differential work is needed to lift this water layer to the top surface. Integrate this differential work now to calculate the overall effort needed to empty the tank.

Rotating the curve x=3y about the y-axis creates the region. Keep in mind that 62.5 = (125 / 2) As a result, using the disk method,

\(\int_{0}^{3} \left(\frac{125}{2} \pi (4-y) (3\sqrt{y})^2\right)\, dy \\ &=\int_{0}^{3} \left(\frac{1125}{2} \pi (4-y) y\right)\, dy &\text\)

Integrate in relation to:

\(y\text{]} \\ &=\left(-\frac{1125}{2} \pi \left(\frac{y^3}{3}-2 y^2\right)\right)\bigg|_{0}^{3} \\ &=\frac{10125 \pi }{2} \\ &\approx 16045.7 \end{align*} \)\)

A: The linear equations are x + y = 125 and x = y + 45.

B: Everyday Angela spends 40 minutes in playing golf.

C: No, it is not possible for Angela to spend 80 minutes playing soccer every day.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Part A:

Let x be the number of minutes Angela plays soccer every day

Let y be the number of minutes Angela plays golf every day

According to the problem statement the linear equations are -

x + y = 125 (total time playing both sports is 125 minutes)

x = y + 45 (Angela plays 45 more minutes of soccer than golf)

Part B:

Substitute x = y + 45 into the first equation -

(y + 45) + y = 125

Use the addition operation -

2y + 45 = 125

2y = 80

y = 40

Angela spends 40 minutes playing golf every day.

Part C:

If Angela spends 80 minutes playing soccer every day, then

x = 80

y + 45 = 80 (using the equation x = y + 45)

y = 35

But this would mean that she plays golf for 35 minutes and soccer for 80 minutes, which adds up to a total of 115 minutes.

This is not possible since the problem states that Angela plays both sports for a total of 125 minutes every day.

Therefore, it is not possible for Angela to have spent 80 minutes playing soccer every day.

P(2 red balls without replacement) = P(1st red ball) x P(2nd red ball | 1st red ball is red), where P is probability.

The probability of getting 2 red balls with replacement is the probability of drawing a red ball multiplied by the probability of drawing a second red ball. This can be written as P(2 red balls with replacement) = P(1st red ball) x P(2nd red ball).

The probability of drawing a second red ball given that the first ball drawn was red is the probability of drawing a red ball given that the first ball drawn was red. This can be written as P(2nd red ball | 1st red ball is red) = P(2nd red ball | 1st red ball is red).

Therefore , the solution of the given problem of angles comes out to be  M∠R measured at 45.4 degrees, to the closest tenth.

The intersection of the lines that form a skew's ends determines the size of its biggest and smallest walls. There's a possibility that two paths will intersect at a junction. Angle is another outcome of two things interacting. They mirror dihedral forms the most. A two-dimensional curve can be created by placing two line beams in various configurations between their ends.

Here,

To determine the size of angle R in triangular PQR, we can apply the Law of Cosines:

=> cos(R) = (PQ₂ + PR₂ - QR₂) / (2 * PQ * PR)

=>  cos(R) = (5.4₂ + 6.2₂ - 3.6₂) / (2 * 5.4 * 6.2)

=>  cos(R) = 0.6960917

When we calculate the inverse cosine of both sides, we obtain:

=>  R = cos⁻¹(0.6960917)

=>  R equals 45.4 degrees

Angle R in triangle PQR is therefore measured at 45.4 degrees, to the closest tenth.

The probability of randomly forming the word "woord logic" is:Probability = 1 / (10! / (2!))

To calculate the probability of forming the word "woord logic" by randomly arranging the letters l, o, g, i, c, we need to consider the total number of possible arrangements and the number of arrangements that result in the desired word.

The word "woord logic" has 10 letters in total. Among these letters, there are 2 o's and the remaining letters appear only once.

The total number of possible arrangements is given by the factorial of the total number of letters:

Total arrangements = 10!

However, since the letter "o" appears twice, we need to divide by the factorial of the number of repeated letters:

Total arrangements = 10! / (2!)

To calculate the number of arrangements that result in "woord logic," we consider that the arrangement of "woord logic" is unique and distinct. Thus, there is only one arrangement that matches the desired word.Simplifying this expression would yield the exact probability.

Answer:

a. Angel has a greater flat fee

b. Difference = $130

Step-by-step explanation:

Given

Rose:

\(Flat\ Fee = \$50\)

\(Rate = \$12\)

Angel

Guests --- Charges

10 -------- $180

15 -------- $255

25 -------- $405

30 -------- $480

Solving (a): Who charges the greater flat fee?

We have that the flat fee of Rose is:

\(Flat\ Fee = \$50\)

For Angel, we need to determine the equation of the given table

Start by calculating the slope (m) of the table

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Where x and y represent any two corresponding values of the guests and the charges.

\((x_1,y_1) = (10, 180)\)

\((x_2,y_2) = (30, 480)\)

So: \(m = \frac{y_2 - y_1}{x_2 - x_1}\) becomes

\(m = \frac{480 - 180}{30 - 10}\)

\(m = \frac{300}{20}\)

\(m = 15\)

Next, we calculate the equation using:

\(y - y_1 = m(x - x_1)\)

Where

\(m = 15\)

\((x_1,y_1) = (10, 180)\)

\(y - 180 = 15(x - 10)\)

\(y - 180 = 15x - 150\)

Add 180 to both sides

\(y - 180 + 180 = 15x - 150 + 180\)

\(y= 15x + 30\)

From the equation above:

The slope = 15 --- This represents the hourly rate

and

y intercept = 30 --- This represents the flat fee

This is better represented as:

Angel

\(Flat\ Fee = \$30\)

\(Rate = \$15\)

and

Rose:

\(Flat\ Fee = \$50\)

\(Rate = \$12\)

By comparison, Angel has a greater flat fee

Solving (b): Difference between total charges of 50 guests for both caterers.

For angel, the equation is:

\(y= 15x + 30\)

and x = 50.

So:

\(y = 15 * 50 + 30\)

\(y = 750 + 30\)

\(y = 780\)

For Rose,

First, we need to determine the equation.

\(Flat\ Fee = \$50\)

\(Rate = \$12\)

The equation is:

\(y = Flat\ Fee + Rate * x\)

\(y = 50 + 12 * x\)

So, the total charges for 50 guests is:

\(y = 50 + 12 * 50\)

\(y = 50 + 600\)

\(y = 650\)

The difference is then calculates as:

\(Difference = 780 - 650\)

\(Difference = \$130\)

Answer:

  25°, 65°

Step-by-step explanation:

Essentially, you want two angles that have a sum of 90 degrees and a difference of 40 degrees.

The smaller is half the sum less half the difference: 90/2 -40/2 = 45 -20 = 25.

The larger is half the sum plus half the difference: 90/2 +40/2 = 45 +20 = 65.

Of course, once you know either value, you can add or subtract the difference (as needed) to find the other value.

The two angles are 25° and 65°.
