determine whether the table repersents a discrete probability distribution

Answers

Answer 1

The discrete probability distribution is discussed above.

What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Given is discrete probability distribution.

A probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment.A discrete probability distribution is the probability distribution of a random variable that can take on only a countable number of values which means that the probability of any event  {E} can be expressed as a (finite or countably infinite) sum.Mathematically, we can write it as : [tex]${\displaystyle P(X\in E)=\sum _{\omega \in A}P(X=\omega )}[/tex].A discrete probability distribution is often represented with Dirac measures, the probability distributions of deterministic random variables. If {E} is any event, then : [tex]${\displaystyle P(X\in E)=\sum _{\omega \in A}p(\omega )\delta _{\omega }(E)}[/tex].Mathematically, we can write the equivalent formula as -

        [tex]${\displaystyle P(X\in E)=\sum _{\omega \in A}p(\omega )\delta _{\omega }(E)} =[/tex]        

       [tex]${\displaystyle P(X\in E)=\int _{E}f(x)\,dx=\sum _{\omega \in A}p(\omega )\int _{E}\delta (x-\omega )=\sum _{\omega \in A\cap E}p(\omega )}[/tex]

Therefore, the discrete probability distribution is discussed above.

How do you find a specific term in a binomial expansion?.

Answers

The easiest way to find a specific term in a binomial expansion is to use the binomial theorem.

The binomial theorem is a fundamental theorem in mathematics that is used to expand expressions which involve two terms, known as binomials, raised to a power.

The binomial theorem states that for any non-negative integer n, the expansion of (x+y)ⁿ is given by the sum of all terms of the form (xⁿ-k)(y^k)/k! where k ranges from 0 to n. This theorem can be used to calculate any term of a binomial expansion.

For example, to calculate the third term of (x+y)⁵, set k = 2 and substitute the appropriate values into the expression (x⁵-2)(y²)/2! which gives 5x³y². This is the third term of (x+y)⁵. The binomial theorem is a powerful tool that can be used to simplify, expand and simplify expressions involving binomials.

A college student is choosing between two data plans for her new cell phone. Both plans include an allowance of 2 gigabytes of data per month. The monthly cost of each option can be seen as a function and represented with an equation:



Option A: `A(x)=60`

Option B: `B(x)=10x+25`



In each function, the input, `x`, represents the gigabytes of data used over the monthly allowance.



Describe each data plan in words.

Answers

The functions for the total cost per month for data use are linear in each of the given options.

Correct responses;

1. A(1) = 60,   B(1) = 35

2. A(7.5) = 60,   B(7.5) = 100

3. The monthly charge for Option A fixed. The monthly charge for Option B includes a fixed monthly fee and $10 per gigabyte used.

4. Please find attached the combined graph of Option A and Option B. Option B is more affordable when the (extra) data usage is less than 3.5 gigabytes each month.

The amount of gigabytes of data the student would have for $50 is 2.5 gigabytes.

What is an expression?

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given parameters are;

Both plans data allowance per month = 2 gigabytes

The monthly cost for each option is;

Option A: A(x) = 60 = Constant

Option B: B(x) = 10·x + 25

Solution:

1. The values of A(1) and B(1) are;

A(1) = 60

B(1) = 10 × 1 + 25 = 35

Therefore;

A(1) = $60

B(1) = $35

2. The values of A(7.5), and B(7.5) are;

A(7.5) = 60

B(7.5) = 10 × 7.5 + 25 = 100

A(7.5) = $60

B(7.5) = $100

3. The description of each data plan are;

Option A

The data plan of option A has a fixed charge of $60

Option B

The charges on the data plan on option B consist of a fixed monthly charge of $25, and $10 per gigabyte of data used.

4. Please find attached the graph of the functions of Option A and Option B. From the graph, the most affordable plan to use based on the data usage is;

Option B; If the data used a month, x < 3.5 gigabytes

Option A; If the data used a month, x > 3.5 gigabytes

Either Option A or Option B if the data usage per month is exactly 3.5 gigabytes

The amount the student budgets per month = is $50

By using Option B, we have;

B(x) = 10·x + 25 = 50

10·x = 50 - 25 = 25

x = 25 / 10 = 2.5

At $50, the amount of gigabytes the student can get is x = 2.5 gigabytes

Part A
Solve the system by ELIMINATION!! Show your work!

Answers

Answer:

a T-shirt = $31

a sweatshirt = $44

Step-by-step explanation:

Let T represent T-shirts and S represent sweatshirts.

Jayden sells 9 T-shirts and 3 sweatshirts for $420:

9T + 3S = 420

Carson sells 1 T-shirt and 6 sweatshirts for $296:

T + 6S = 296

Multiply second equation with -9

-9T - 54S = -2,664

Now find the the sum of two equation

9T - 9T + 3S - 54S = 420 - 2,664

-51S = -2,244

Divide both sides by -51

S = 44 is the price for a sweatshirt, for the price of a T-shirt:

T + 6S = 296

Rewrite equation by replacing S by 44

T + 6×44 = 296

T + 264 = 296

Subtract 264 from boths sides

T = 31

How many solutions does the linear equation 3x 11y 10 have?.

Answers

The linear equation 3x + 11y = 10 has one solution.

The given linear equation is 3x + 11y = 10. To find the number of solutions for this equation, we can use the following method:

1. Rewrite the equation in the form of y = mx + c, where m is the coefficient of x and c is the constant term.

   3x + 11y = 10

   -3x/11 = y -10/11

   y = -3/11x +10/11

2. Check the slope and the y-intercept, if the slope is infinite, it means the equation is a vertical line and it has no solutions, if the y-intercept is infinite, it means the equation is a horizontal line and it has infinitely many solutions.

In this case, the slope is -3/11 which is a finite value, also the y-intercept is (0,10/11) which is a finite value, so the equation is not a vertical or horizontal line, it is a standard form of a linear equation, and it has a unique solution.

Therefore, the linear equation 3x + 11y = 10 has one solution.

Answers

Answer:

each bag of trail mix costs $2 and each loaf of pumpkin bread costs $9.

Step-by-step explanation:

To find the cost of each item, we need to solve the system of equations.

We can use substitution method:

3x + 2y = 24

x + y = 11

Solving for x in the second equation:

x = 11 - y

Substituting this into the first equation:

3(11 - y) + 2y = 24

Solving for y:

33 - 3y + 2y = 24

-y = -9

y = 9

Then we can use y = 9 in the equation x = 11 - y to find x:

x = 11 - 9 = 2

So each bag of trail mix costs $2 and each loaf of pumpkin bread costs $9.

Answer:

The updated mean after adding 43 to the data set is 41.

Step-by-step explanation:

In statistics, the median is a measure of central tendency that represents the middle value of a data set when it is arranged in ascending or descending order.

We know that the general formula for finding median,

If the total number of data points (n) is odd, the median is the value at the  [tex]\frac{n+1}{2}[/tex] th position.

If the total number of data points (n) is even, the median is the average of the values at the [tex]\frac{n}{2}[/tex] th and [tex]\frac{n}{2} +1[/tex] th  positions.

Given data set: 31, 41, 50, 28, 52, 38, 56, 27

Case 1: Calculate the current median

Arrange the data set in ascending order:

27, 28, 31, 38, 41, 50, 52, 56

Determine the total number of data points (n):

In this case, there are 8 data points.

Calculate the median using the general formula

In Case 1, since n = 8, it is an even number. Thus, the median is the average of the values at the 8/2 = 4th and (8/2 + 1) = 5th positions, which are 38 and 41, respectively.

Calculate the median: [tex]\frac{38 + 41}{2}[/tex] = [tex]\frac{79}{2}[/tex] = 39.5

Hence it is verified

Case 2: Calculate the updated mean

Add the new number to the data set

Add 43 to the data set:
27, 28, 31, 38, 41, 50, 52, 56, 43

Arrange the updated data set in ascending order:
27, 28, 31, 38, 41, 43, 50, 52, 56

Determine the new total number of data points (n):
In this case, there are 9 data points.

Calculate the new median using the general formula:

In case 2, since n = 9, it is an odd number. Thus, the median is the value at the (9+1)/2 = 5th position, which is 41.

Therefore, after adding 43 to the data set, the new median becomes 41.

The number that belongs in the green box is 14.7. The solution has been obtained using law of sines.

What is law of sines?

According to the law of sines, all of the angles in the problem must have an equal ratio between the sine of each angle and the length of the side opposite to that angle.

As per law of sines,

sin A/a =  sin B/b = sin C/c

In the figure, we are given two angles and we know that in a triangle sum of all angles is 180°.

Therefore,

125° + 32° + x = 180°

x= 23°

Let the side be 'a'

Using law of sines,

⇒sin 125°/a = sin 23°/7

⇒a sin 23° = 7sin 125°

⇒a = 7sin 125°/sin 23°    (Dividing both sides by sin 23°)

a = 14.7

If the base is e and we are dealing with the natural log, then the inverse of f(x) = ln(x) is f^-1(y) = e^y.Rewriting these relationships substituting f(x) with y and f^-1(y) with x, we see that the inverse of y = log subb(x) is x = b^y and the inverse of y = ln(x) is x = e^y. Both the inverse and the original function state the same relationship,

so now,

f(x)=log base g x.

g^f(x)=x

g^y=f(y).

f(y)=g^y.

1. In estimating the selected objects in terms of
Width and Mass, what difficulties did you encount
Explain​

Answers

Estimating the width and mass of objects necessitates meticulous attention to detail, a thorough understanding of the measurement tools and techniques employed, and an awareness of any potential difficulties.

Estimating the width and mass of objects can be difficult in general for several reasons:

Precision of measurement: Depending on the tools used, the precision of measurement can affect the accuracy of the estimate. The shape of the object being measured can also have an impact on the estimate. It can be difficult, for example, to precisely measure the width of an irregularly shaped object.Object composition: The object's composition, such as its density or rigidity, can have an impact on the estimate.External factors such as temperature or humidity can affect the measurement, making it more difficult to obtain an accurate estimate.

Suppose that x and y vary inversely, and x = 12 when y = 8 . Write the function that models the inverse variation.

Answers

Answer:

96/x

Step-by-step explanation:

When two variables x and y vary inversely, their product is a constant. Therefore, the function that models the inverse variation between x and y is:

x*y = k

where k is the constant of proportionality.

We can use the given information to find the value of k:

x = 12 when y = 8

so, k = xy = 128 = 96

Now we can use this value of k to write the function that models the inverse variation:

x*y = 96

To find the inverse variation, we divide both sides by y,

x = 96/y

Alternatively, we can write y = 96/x

So, the function that models the inverse variation between x and y is either x = 96/y or y = 96/x

A graph which has a slope of negative three halves and a y-intercept of 3 include the following: C. graph of a line passing through the points 0 comma 3 and 2 comma 0.

What is y-intercept?

In Mathematics, the y-intercept is also known as an initial value and the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

From the information provided above, the slope and data points on this line include the following:

Points on x-axis (x) = (0, 2).Points on y-axis (y) = (3, 0).

In Mathematics and Geometry, the slope of any straight line can be calculated by using this this mathematical equation (expression);

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Substituting the given points into the slope formula, we have the following;

Slope (m) = (0 - 3)/(2 - 0)

Slope (m) = -3/2

Therefore, the required equation based on a y-intercept of 3 is y = -3x/2 + 3.

Given ABC with A(-4,1), B(8,-1), and C(-2,9), write the equation of the line containing
midsegment XZ in standard form, where X is the midpoint of AB and Z is the midpoint of
BC.
4x=y=8
4x+y=8
4x-y=-8
4x + y = -8

Answers

The equation of the line containing midsegment XZ in the standard form is:

y = 2x +0

What is the Equation of line?

The equation of a line is a mathematical representation of the relationship between the variables x and y on a coordinate plane. It is typically written in the form "y = mx + b", where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

The equation of the line containing the midsegment of a triangle can be found by taking the average of the coordinates of the midpoints of the two line segments that make up the midsegment.

First, we need to find the midpoint of AB:

Midpoint of AB = ((-4+8)/2, (1+-1)/2) = (2,0)

Then, we need to find the midpoint of BC:

Midpoint of BC = ((8+-2)/2, (-1+9)/2) = (3,4)

The equation of line XZ can be found by taking the average of the coordinates of X and Z, and solving for y:

y = (0+4)/2 = 2

x = (2+3)/2 = 2.5

Hence, the equation of the line containing midsegment XZ in the standard form is:

y = 2x +0

Karen spent 135 minutes riding her bike and swimming in the race.

Algebra is a common thread that runs through practically all of mathematics. It involves the study of variables and the rules for manipulating them in formulas.

You must add the time Karen spent swimming and riding her bike to get the total amount of time she spent doing both during the race.

First, we need to convert Karen's bike riding time to minutes:

1 1/2 hours = 1 1/2 * 60 minutes = 90 minutes

Now we can add up Karen's bike riding time and swimming time:

90 minutes + 45 minutes = 135 minutes

So Karen spent 135 minutes riding her bike and swimming in the race.
