In probability theory, a Venn diagram is a diagrammatic representation of sets that shows all possible logical relations between them. Venn diagrams are widely used in probability and statistics to visualize the relationship between different sets of data.

The given Venn diagram shows the relationship between three sets, A, B, and C. In order to calculate probabilities using a Venn diagram, we need to know the number of elements or members in each set, as well as any overlapping regions.

We can then use these numbers to calculate the probability of different outcomes.Let's consider two possible probabilities from the given Venn diagram:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22. The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3The first probability can be calculated by dividing the number of elements in the overlapping region of sets A and B (which is 0.1) by the total number of elements in set B (which is 0.5).

This gives us a probability of 0.22 or 22%.The second probability can be calculated by dividing the number of elements in the union of sets B and C (which is 0.2) by the total number of elements in either set B or set C (which is 0.6). This gives us a probability of 1/3 or approximately 33%.

Therefore, the correct probabilities are:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22.

The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3

The volume of cylinder is 2352π in³ while the volume of cone is 784π in³. The volume of the cylinder is three times the volume of the cone

An equation is an expression that shows the relationship between two or more numbers and variables.

A cylinder has radius 14 inches and height 12 inches. A cone has the same radius and height.

Volume of cylinder = π * radius² * height = π * 14² * 12 = 2352π in³

Volume of cone = (1/3) * π * radius² * height = (1/3) * π * 14² * 12 = 784π in³

To determine if a function has a vertical asymptote, you need to consider its behavior as the input approaches certain values.

A vertical asymptote occurs when the function approaches positive or negative infinity as the input approaches a specific value. Here's how you can determine if a function has a vertical asymptote:

Check for restrictions in the domain: Look for values of the input variable where the function is undefined or has a division by zero. These can indicate potential vertical asymptotes.

Evaluate the limit as the input approaches the suspected values: Calculate the limit of the function as the input approaches the suspected values from both sides (approaching from the left and right). If the limit approaches positive or negative infinity, a vertical asymptote exists at that value.

For example, if a rational function has a denominator that becomes zero at a certain value, such as x = 2, evaluate the limits of the function as x approaches 2 from the left and right. If the limits are positive or negative infinity, then there is a vertical asymptote at x = 2.

In summary, to determine if a function has a vertical asymptote, check for restrictions in the domain and evaluate the limits as the input approaches suspected values. If the limits approach positive or negative infinity, there is a vertical asymptote at that value.

128 subsets

127 proper subsets

=======================================================

Explanation:

Set P is the set of letters from the word "PREPOSTEROUS"

So P = {P,R,E,P,O,S,T,E,R,O,U,S}

But we must toss out any duplicate items. After doing so we have

P = {P, R, E, O, S, T, U}

which in alphabetical order would be

P = {E, O, P, R, S, T, U}

There are n = 7 unique letters in this set.

So there are 2^n = 2^7 = 128 subsets and (2^n)-1 = (2^7)-1 = 128-1 = 127 proper subsets.

---------------------

note: If B is a subset of A, then everything inside B is also inside A. But not necessarily the other way around. A proper subset is one where set B is smaller than set A (it has at least one fewer items).

Let z = k. Then f(z) = 2z = 2k = e. Thus, f is surjective.Therefore, since f is both injective and surjective, it is a bijection between Z and E. Thus, |Z| = |E|, and the statement is true.

The statement Z and the set E of even natural numbers having the same cardinality is true. The proof follows. Definition of cardinality, Cardinality is defined as a way of representing the size of a set. The cardinality of a set is determined by counting the number of elements in the set.

We write the cardinality of a set X as |X|. If a set Y is in a one-to-one correspondence with set X, then their cardinalities are equal. We write |Y| = |X|.

Proof that |Z| = |E|To prove that |Z| = |E|, we need to show that there exists a bijection (one-to-one correspondence) between set Z and set E.

Consider the function f: Z → E defined by f(x) = 2x. Since Z and E have infinite cardinality, we need to show that this function is both injective (one-to-one) and surjective (onto).Injectivity: Assume that f(a) = f(b). Then 2a = 2b which implies that a = b. Thus, f is injective.

Surjectivity: Given any even number e ∈ E, we need to show that there exists an integer z ∈ Z such that f(z) = e. Let e be any even number. Then e = 2k for some integer k.

Answer:

  1/2

Step-by-step explanation:

The "Pythagorean relation" between trig functions can be used to find the sine.

The relation between sine and cosine is the identity ...

  sin(x)² +cos(x)² = 1

This can be solved for sin(x) in terms of cos(x):

  sin(x) = √(1 -cos(x)²)

For the present case, using the given cosine value, we find ...

  sin(x) = √(1 -(√3/2)²) = √(1 -3/4) = √(1/4)

  sin(x) = 1/2

Additional comment

The sine and cosine of an angle are the y and x coordinates (respectively) of the corresponding point on the unit circle. The right triangle with these legs will satisfy the Pythagorean theorem with ...

Question: jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar

Find: how much money she has in her coin jar

Solution: let's make an equation for this problem

She has 4 more dimes than nikels:y= x+4 Let's use this value for y in the next equation:

she has 18 nickels and 36-18= 18 dimes

The required Jasmine has 16 nickles and 20 dimes which constitute  $2.80 in her coin jar.

Let's use the given information to set up a system of equations to solve for the number of nickels (x) and dimes (y) in Jasmine's coin jar.

We are given that Jasmine has a total of 36 coins in her jar, so we have the equation:

x + y = 36 -- Equation 1

We are also given that Jasmine has four more dimes than nickels, which can be expressed as:

y = x + 4 -- Equation 2

Now, let's solve this system of equations. We can substitute Equation 2 into Equation 1 to eliminate y:

x + (x + 4) = 36

2x = 36 - 4

x = 16

Now that we have the value of x, we can substitute it back into Equation 2 to find y:

y = x + 4

y = 16 + 4

y = 20

Therefore, Jasmine has 16 nickels (x) and 20 dimes (y) in her coin jar.

To find the total amount of money she has, we need to calculate the value of the nickels and dimes separately:

Value of nickels = 0.05 * 16 = $0.80

Value of dimes = 0.10 * 20 = $2.00

The total amount of money in her coin jar is:

$0.80 + $2.00 = $2.80

Jasmine has $2.80 in her coin jar.

Therefore, the explicit formula for f ο g is f(g(x)) = 10x + 17.

(b) g ο f:

g(f(x)) = g(2x + 3)

= 5(2x + 3) + 7

= 10x + 15 + 7

= 10x + 22

Therefore, the explicit formula for g ο f is g(f(x)) = 10x + 22.

(c) f ο h:

f(h(x)) = f(\(x^{2}\) + 1)

= 2(\(x^{2}\) + 1) + 3

= 2\(x^{2}\) + 2 + 3

= 2\(x^{2}\) + 5

Therefore, the explicit formula for f ο h is f(h(x)) = 2\(x^{2}\) + 5.

(d) h ο f:

h(f(x)) = h(2x + 3)

= \((2x+3)^{2}\) + 1

= 4\(x^{2}\) + 12x + 9 + 1

= 4\(x^{2}\) + 12x + 10

Therefore, the explicit formula for h ο f is h(f(x)) = 4\(x^{2}\) + 12x + 10.

the ratio of cost to size of first pizza is 0.103 $ per square inch of pizza.

Since the 14 inch diameter pizza has a lower cost (0.103 $) than the 8 inch diameter pizza (0.199 $), the 14 inch diameter pizza is the "better buy".

The better pizza has a higher "area-to-cost" ratio (high area, low cost). The first pizza has a ratio of 16π/10 = 5.027, and the second pizza has a ratio of 49π/16 = 9.621. The second pizza's ratio is higher, so it is the better buy.
