if x and y and w are independent binomial random variables with parameters (n,p), (m,p) and (k,p)respectively, with p representing the probability of success, what is the distribution of x y w?

The point (11,11) will lie on the graph of the function f(x) = IxI

What is coordinate?

The x-coordinate informs us of a point's separation from the y-axis, which is the vertical axis. The abscissa is another term for the x-coordinate. The y-coordinate shows how far a point is from the horizontal axis, or x-axis. The term "ordinate" also applies to the y-coordinate.

the function: f(x) = IxI

The function will have every positive and negative integer contained within itself.

So coordinates of another point with the same y value (11,11) will lies on the graph so as (-11,11).

Hence point (11,11) will lie on the graph of the function f(x) = IxI

Following the Sampling Theorem of statistics, the answer is True.

The study of statistics focuses on gathering, organizing, organizing, analyzing, interpreting, and presenting data.

Each member of the group or community has an equal chance of being chosen when using probability sampling. According to probability-based statistical theory, this indicates that the sample is more likely to match the larger population, allowing for the drawing of more precise conclusions about the latter.

Yes, the quota sampling process occurs when the available or accessible people or material are selected. Due to large population size, Sampling process is preferred.

Since, Statistics convey characteristics of data to us. So yes, The sample is weighted so that predetermined characteristics are represented.

A 95% confidence interval for percent of american adults who believe in aliens:  (0.6578, 0.7822)

In this question we have been given that in a survey conducted on an srs of 200 american adults, 72% of them said they believed in aliens

We need to find the 95% confidence interval for percent of american adults who believe in aliens.

95% confidence interval = (p ± z√[p(1 - p)/n])

Here, n = 200

p = 72%

p = 0.72

And the z-score for 95% confidence interval is 1.960

The upper limit of interval would be,

(p + z√[p(1 - p)/n])

= 0.72 + 1.960 √[0.72(1 - 0.72)/200]

= 0.72 + 1.960 √[(0.72 * 0.28)/200]

= 0.72 + 1.960 √0.001008

= 0.72 + 0.0622

= 0.7822

The lower limit of interval would be,

(p - z√[p(1 - p)/n])

= 0.72 - 1.960 √[0.72(1 - 0.72)/200]

= 0.72 - 1.960 √[(0.72 * 0.28)/200]

= 0.72 - 1.960 √0.001008

= 0.72 - 0.0622

= 0.6578

Therefore, a 95% confidence interval = (0.6578, 0.7822)

Division is a basic procedure in which an integer is divided. It's best to imagine of it as a number of things being distributed among a particular number of persons, such as in the previous example. In mathematics, division is the process of dividing a number into equal parts and determining how many equal parts can be made. For instance, dividing 15 by 3 implies dividing 15 into three equal groups of five. Dividend Divisor = Quotient + Remainder is the formula for dividing two numbers. The dividend is the number that is being divided in this case. The divisor is the number, which divides the number (dividend) into equal parts.

Here,

37 - 21 and 1/4 = 36 and 4/4 - 21 and 1/4 = 15 and 3/4 = 63/4

63/4 divided by 1 and 3/4 = 63/4  divided by 7/4 = 63/4 * 4/7 = 9 years

Answer:

Question 1: Calculate the coordinates of 2 points. You know that the value of the Y coordinate in a point is 4 times the value of the x in the same point. Once you figure out the points, put them on the graph and draw a straight line through them with a ruler.

Question 2: What number do you multiply 5 by to get 12? You multiply that same number by the 375 to get the value in the corresponding row. That's called proportion.

Question 3: You can find the proportion between the two values (distance and energy). Its how many times bigger (or smaller) the values are in relation to each other. You can use this proportion for the scale of the graph so that the location of points are easier understood in relation to each other and discernable all by your eye.

After solving the equation, the value obtained for x will be equal to 5.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.

Step-by-step explanation:

The answer is to the 7 1/3 th mark.

Consider the provided question,

Since, in wide cylinder, water rises to 4th mark while in narrow cylinder same amount of water rises to 6th mark.

So, 6th mark on narrow cylinder = 4th mark on the wide cylinder which implies that 3rd on narrow cylinder = 2th mark on the wide cylinder

From the above,

Since, 3rd on narrow cylinder = 2th mark on the wide cylinder that means 1 mark on narrow cylinder is equal to 2/3 the of the 1st mark of the wider cylinder.

Hence the 11th mark of the narrow cylinder is equal to the

The required equation of the line is 9/4x with a slope of 9/4 and a y-intercept of 0.

The value of the steepness or the direction of a line in a coordinate plane is known as a line's slope, often referred to as a line's gradient. With a line's equation or the coordinates of a point along the straight line, slope can be computed using a variety of ways.

The slope of a line indicates the steepness and direction of the line. Finding the difference between the coordinates of the locations will allow you to quickly compute the slope of a straight line connecting two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The letter "m" is typically used to signify slope.

The slope of the line is a tangent angle made by line with horizontal.

i.e. m = tan x, where x in degrees.

Let the given values be m = 9/4 and c = 0

Standard equation of the line, y = mx + c

A right-angled triangle can be formed by the string, the height of the kite, and the horizontal distance along the ground to a point directly beneath the kite.

The string represents the hypotenuse (200 feet), and the height (120 feet) represents the opposite side.

The trigonometric ratio sin can be used to calculate the angle between the string and the ground.

A polynomial is a mathematical formula that involves only the operations of addition, subtraction, multiplication, and powers of positive integers of the variables and is composed of coefficients and indeterminates.

An example of a polynomial with a single indeterminate x is x² - 4x + 7.

So, we have the equation:

3x²+4x²-7=0

Now, calculate the zero of the polynomial as follows:

When x = 0:

P(x) = 3x² + 4x² - 7 = 0

P(0) = 3(0)² + 4(0)² - 7

P(0) = - 7

Not zero

When x = 1:

P(x) = 3x² + 4x² - 7 = 0

P(1) = 3(1)² + 4(1)² - 7

P(1) = 3 + 4 - 7

P(1) = 0

By adding up all the possible ways to distribute the coupon and subtracting it from the possible ways to distribute the 10 coupons to the 15 men, we can determine the total number of ways at least a woman can receive a coupon.

- The entire number of options for dividing the coupons among the 20 customers is the same as the total number of ways to choose a subset of 10 items from a set of 20.

In other terms, 20/10 = 20!/ 10!10 is the combinatorial number of 20 and 10.

- We must use the same calculation as above, but with a set of 15 items rather than 20, to get the total number of alternatives for distributing the coupons among the 15 males.

We now have 15/10, which is 15!/10!5! possibilities.

To ensure that at least one woman receives a coupon, we have 20/10 - 15/10 distribution options.

2. ∠1 = 30°

3. ∠2 = 60°

4. ∠3 = 120°

Step-by-step explanation:

⭐What are supplementary angles?

⭐What are complementary angles?

Set up the equations for the situation:

∠1 + ∠2 = 90

∠2 + ∠3 = 180

x + 2x = 90 . . . (1)

2x + ∠3 = 180 . . . (2)

First, solve for "x" in equation 1:

x + 2x = 90

3x = 90

∴ x = 30

Next, substitute "x" into ∠1 and ∠2 to solve for ∠1 and ∠2:

∠1 = x

∴ ∠1  = 30°

∠2 = 2x

∠2 = 2(30)

∴ ∠2  = 60°

Finally, substitute "x" into equation 2 to solve for ∠3:

2x + ∠3 = 180

2(30) + ∠3 = 180

60 + ∠3 = 180

∴ ∠3 = 120°

Thus, 420 fish were ultimately caught, with 6x standing in for "6 times as much."

The smallest and largest fish range in size from 1 cm to 18 m. 18 m then equals 18 x 100 or 1800 cm. ∴ The length of large fish exceeds that of little fish by 1800 times.
