Work accounts for approximately 60° of the pie chart, or 15.48% of the total 360°.

To calculate a pie chart, first, categorize the data and calculate the total.

Each slice of the pie chart represents a numerical value and has a size proportional to the value.

The sum of all the data is equal to 360°, with the total value always being 100%.

To find the percentage for each slice of the pie chart, divide the categories by the total and convert them into percentages.

Finally, calculate the degrees using the formula (Given Data/Total value of Data) × 360°.

For example, let's say we have data on sleep, work, family care, personal care, and leisure, with a total of 168 hours.

To find the percentage for each category, we can use the following calculations:

Therefore, work accounts for approximately 60° of the pie chart, or 15.48% of the total 360°.

The value of [tex]$g(f(g(f(g(f(g(f(12)))))))) = \frac{5926}{3335}$[/tex] when the function f is applied 8 times and g is applied 8 times alternatively.

The process of applying one function to the result of another is known as function composition. In other words, if we have two functions, f and g, we may combine them to create a new function that accepts an input, processes it though g, and then outputs f.

For the given composite function we start with the innermost function.

Find the value of f(12):

[tex]f(12) = \frac{1+12}{1-12} = -\frac{13}{11}$\\\$g(f(12)) = \frac{-2}{-\frac{13}{11}+1} = \frac{22}{13}$\\$f(g(f(12))) = \frac{1+\frac{22}{13}}{1-\frac{22}{13}} = -\frac{35}{9}$\\$g(f(g(f(12)))) = \frac{-2}{-\frac{35}{9}+1} = \frac{18}{13}$[/tex]

The missing value in the proportion 4:x = 20:10 is 2.

What is proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.

To find the missing value in the proportion 4:x = 20:10, we can use the property that the ratios of the corresponding terms in a proportion are equal.

That is, 4:x = 20:10 is equivalent to the equation -

4 / x = 20 / 10

Simplifying this equation, we get -

4 / x = 2

Multiplying both sides of the equation by x, we get -

4 = 2x

Dividing both sides of the equation by 2, we get:

x = 2

Therefore, the value for x is obtained as 2.

Therefore, the probability that a randomly selected family owns a cat is 0.257. Therefore, the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat is 0.778.

Probability is a branch of mathematics that deals with the study of random events or situations. It involves the quantification of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, with 0 representing impossibility and 1 representing certainty. The theory of probability provides a framework for making predictions, analyzing data, and making decisions in situations involving uncertainty or randomness.

Here,

Let's use the following events:

D: family owns a dog

C: family owns a cat

From the problem statement, we know:

P(D) = 0.3

P(C|D) = 0.2

P(C) = 0.34

1. To find the probability that a randomly selected family owns a cat, we can use the law of total probability:

P(C) = P(C|D) * P(D) + P(C|not D) * P(not D)

We don't know P(C|not D), but we can find it using the fact that P(not D) = 1 - P(D):

P(C|not D) = (P(C) - P(C|D) * P(D)) / P(not D)

P(C|not D) = (0.34 - 0.2 * 0.3) / (1 - 0.3)

P(C|not D) = 0.2857

Substituting the values:

P(C) = 0.2 * 0.3 + 0.2857 * 0.7

P(C) = 0.257

2. To find the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat, we can use Bayes' theorem:

P(not D|C) = P(C|not D) * P(not D) / P(C)

Substituting the values:

P(not D|C) = 0.2857 * 0.7 / 0.257

P(not D|C) = 0.778

The line of best fit for this set of points is y = -1.00x + 9.00.

Coefficient is a value that is used to indicate the degree or amount of a certain property or characteristic. It is usually used in mathematics and physics, and is a numerical measure of how two variables are related. For example, the coefficient of friction is a number that indicates how much resistance there is between two surfaces when one is sliding over the other. In economics, the coefficient of elasticity is used to measure how much of a change in one variable affects a change in another.

Linear regression is a technique used to find the line of best fit for a given set of points. To use linear regression, we must first calculate the mean of all the x and y coordinates. The mean of the x coordinates is 4, and the mean of the y coordinates is 4.5.

We then calculate the sum of the squared differences between the x and y coordinates and their respective means. This sum is 36.5.

Next, we calculate the sum of the products of the differences between the x and y coordinates and their respective means. This sum is -25.

Using the formula for linear regression, we can calculate the slope of the line of best fit. The slope is -1.00.

To calculate the y-intercept of the line of best fit, we use the slope and the mean of the x and y coordinates. The y-intercept is 9.00.

After answering the presented question, we can conclude that They are equation still pleased with the quantity of pizza they received, although it is less than in the previous scenario.

A quotient refers to the result obtained when one quantity is divided by another. For example, if you have 10 apples and you want to divide them equally among 2 people, each person would get 5 apples. The quotient in this case is 5, which represents the number of apples that each person would receive.

The quotient can be expressed in different forms, depending on the situation. If you are dividing two integers, the quotient can be a whole number (also known as an integer quotient) or a fraction (also known as a rational quotient). For example, if you divide 10 by 3, the quotient is 3 with a remainder of 1, which can be expressed as [tex]3 + 1/3[/tex] or as the fraction 10/3.

In algebra, the quotient can also refer to the result obtained when dividing two algebraic expressions. For example, if you divide [tex]x^2 + 3x + 2[/tex] by [tex]x + 1,[/tex] the quotient is [tex]x + 2[/tex], which represents the quotient of the division.

The solution to the differential equation dy/dx = 3x/√(y) with initial condition (0,1) is y = ((9/4) × x² + 1)^(2/3).

Differential equations are used to model a wide variety of physical, biological, and economic systems, including the motion of objects under the influence of forces, the spread of disease in a population, and the behavior of financial markets.

There are many different types of differential equations, including ordinary differential equations (ODEs) and partial differential equations (PDEs). ODEs involve a single independent variable and its derivatives, while PDEs involve multiple independent variables and their derivatives.

To solve the differential equation dy/dx = 3x/√(y), we can separate the variables by multiplying both sides by √(y) and dividing both sides by 3x:

dy/dx = 3x/√(y)

√(y) dy/dx = 3x

√(y) dy = 3x dx

Integrating both sides:

∫√(y) dy = ∫3x dx

(2/3)*y^(3/2) = (3/2)*x² + C

where C is the constant of integration.

To find the value of C, we can use the initial condition (0,1), which means y=1 when x=0:

(2/3)*y^(3/2) = (3/2)*x² + C

(2/3)*1^(3/2) = (3/2)*0² + C

C = (2/3)

Substituting C = 2/3 back into the equation, we get:

(2/3)×y^(3/2) = (3/2) × x² + 2/3

y^(3/2) = (9/4) × x² + 1

y = ((9/4) × x² + 1)^(2/3)

Therefore, the solution to the differential equation dy/dx = 3x/√(y) with initial condition (0,1) is y = ((9/4) × x² + 1)^(2/3).

Answer:

A. To find when the spider's height is at 0 feet, we need to solve the equation h = 33.3t - 16t^2 for t when h = 0. This gives us:

0 = 33.3t - 16t^2

0 = t(33.3 - 16t)

t = 0 or t = 2.08125 (rounded to 5 decimal places)

So the spider's height is at 0 feet at 0 seconds and 2.08125 seconds.

B. To find the spider's height after 1 second, we substitute t = 1 into the equation:

h = 33.3t - 16t^2

h = 33.3(1) - 16(1)^2

h = 17.3 feet

So the spider's height after 1 second is 17.3 feet.

What is sorting?

Sorting is the process of arranging or categorizing a set of items in a particular order or sequence according to specific criteria. It is a fundamental operation in computer science and is used extensively in various applications such as data analysis, information retrieval, and database management.

In general, sorting involves comparing elements of a collection, such as an array or a list, and rearranging them according to a predetermined order. The order can be based on a variety of factors, such as numerical value, alphabetical order, or date/time stamp. The two main categories of sorting algorithms are comparison-based sorting and non-comparison based sorting.

Some common sorting algorithms include bubble sort, insertion sort, selection sort, quicksort, merge sort, and heapsort. Each algorithm has its own advantages and disadvantages, and the choice of algorithm depends on the specific application and the characteristics of the data being sorted.

The two points on the line to graph the function is (0, -16) and (1, -53).

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. The order of the coordinates is crucial, and they are sometimes recognised by their position in an ordered tuple and occasionally by a letter, as in "the x-coordinate". In elementary mathematics, the coordinates are assumed to be real numbers, although they might instead be complex numbers or components of a more abstract system, such a commutative ring.

The given function is:

q(x)=3x−(2+5x)8

To find two points on the line to graph the function we substitute different values of x.

For x = 0:

q(x)=3x−(2+5x)8

q(0) = 3(0) - (2 + 5(0))8

q(0) = -16

For x = 1:

q(x)=3x−(2+5x)8

q(1) = 3(1) - (2 + 5(1))8

q(1) = 3 - (7)8

q(1) = -53

Hence, the two points on the line to graph the function is (0, -16) and (1, -53).
