What are Combinations?

The number of ways of selecting r objects from n unlike objects is:

ⁿCₓ = n! / ( ( n - x )! x! )

Given data ,

The number of fresher men in sorority = 12 fresher men

The number of sophomores in sorority = 9 sophomores

In the conference ,

The number of fresher men from sorority =3 fresher men

The number of sophomores from sorority = 2 sophomores

To calculate the number of different ways the conference attendees be selected is by using combination

So , the combination will become

Selecting 3 fresher men from 12 and selecting 2 sophomores from 9

And , the equation for combination is

ⁿCₓ = n! / ( ( n - x )! x! )

The combination is ¹²C₃ x ⁹P₂

¹²C₃ x ⁹P₂ = 12! / ( 9! 3! )  x  9! / ( 7! 2! )

                = ( 12 x 11 x 10 ) / ( 3 x 2 )  x  ( 9 x 8 ) / 2

                = 1320 / 6  x  72 / 2

                = 220 x 36

                = 7920 ways

Hence , the number of different ways the conference attendees be selected is 7920 ways

* Two cars started to move from C and from D, towards one another. The car that starts at point C moves twice as fast as the car that starts at point D. How far from Boston will these two cars meet?

Answers

Answer:

The answer to the question is

If Boston is at D and C is 90 km away from Boston, then the two cars will meet at 30 km from Boston.

Step-by-step explanation:

Let the speed of the car that start from C = V₁

Let the speed of the car that start from D = V₂

Therefore where V₁ = 2·V₂

We have at time t when the cars meet the distance covered by the car that start from C will be V₁×t = 2·V₂×t, while the distance of the other car will be

V₂×t

Which means that the distance covered by the car that start from C is twice that of the car that start from D

Hence if Boston is located at D which is 90 km from C then both cars will meet at

90 km /3 = 30 km from Boston as the car originating from Boston would only have covered 30 km when the two cars meet.

920 mg

200 mg

449 mg

360 mg

600 mg

Answers

Answer:

360 mg.

Step-by-step explanation:

The medicine has a decay rate of 40% in 25 hours, which means after 24 hours its amount will be 100% - 40% = 60% it's original value.

Let us call [tex]t[/tex] the number of hours passed and [tex]d[/tex] the number of 24-hours passed, then we know that

[tex]t = 24d[/tex].

Now, the amount [tex]c[/tex] of medicine left after time [tex]d[/tex] (dth 24-hour) will be

[tex]c = 1000(0.6)^d[/tex]

and since [tex]t =24d[/tex], we have

[tex]$\boxed{c = 1000(0.6)^{\frac{t}{24} }}$[/tex]

We now use this equation to find the final amount after [tex]t =48 hours[/tex]:

Coach Martinez will order 2 pairs of shorts and 3 shirts for each player. There are 12 members on the team. If each pair of shorts costs x dollars and each shirt costs y dollars, which expression represents the total cost of his order?

Answers

The expression [tex]\(24x + 36y\)[/tex] represents the total cost of Coach Martinez's order for 12 team members, where [tex]\(x\)[/tex] is the cost of each pair of shorts and [tex]\(y\)[/tex] is the cost of each shirt.

The total cost [tex](\(C\))[/tex] of Coach Martinez's order can be represented by the expression:

[tex]\[ C = \text{Cost of shorts} + \text{Cost of shirts} \][/tex]

Since Coach Martinez is ordering 2 pairs of shorts and 3 shirts for each player, and there are 12 members on the team, the expression for the total cost is:

[tex]\[ C = 12 \cdot (2x) + 12 \cdot (3y) \][/tex]

Simplify this expression to get the total cost:

[tex]\[ C = 24x + 36y \][/tex]

Therefore, the expression [tex]\(24x + 36y\)[/tex] represents the total cost of Coach Martinez's order for 12 team members, where [tex]\(x\)[/tex] is the cost of each pair of shorts and [tex]\(y\)[/tex] is the cost of each shirt.

In a round robin tennis tournament, each player plays every other player exactly once. Use induction to show that if there are n players there will be n(n − 1)/2 games.

Answers

Answer:

Step-by-step explanation:

given that in a round robin tennis tournament, each player plays every other player exactly once.

Suppose there are two players i.e. n=2, we have only one match satisfies

[tex]\frac{2(2-1)}{2} =1[/tex]

Hence P(2) is true

Assume P(k) is true.  For k players no of matches played

= [tex]\frac{k(k-1)}{2}[/tex]

To prove true for n = k+1

If to k players one new player is introduced, then the new player should play all the k players to have the condition satisfied

i.e. no of matches = no for k players + k

= [tex]\frac{k(k-1)}{2} +k\\= \frac{k^2-k+2k}{2} \\= \frac{(k+1)k}{2}[/tex]

So if true for n =k, then true for n =k+1

Already true for n =2

By induction true for all natural numbers starting from 2.

Answers

Answer:

[tex]1\frac{1}{4} \ cups \ of \ juice[/tex] ,[tex]2\frac{2}{3}\ cups \ of \ juice[/tex]

Step-by-step explanation:

Given:

Number of people in a group = 4

Each person gets cup of juice = [tex]\frac{1}{3}[/tex]

Question asked:

How much tomato juice is needed for a group of four people ?

How much tomato juice is needed if they each get 2/3 cup of juice ?

Solution:

Unitary method:

In case of each person gets [tex]\frac{1}{3}[/tex] up of juice.

1 person gets cup of juice = [tex]\frac{1}{3}[/tex]

4 persons gets cup of juice = [tex]\frac{1}{3} \times4=\frac{4}{3} =1\frac{1}{3} \ cup \ of\ juice[/tex]

Therefore, [tex]1\frac{1}{4} \ cups \ of \ juice[/tex] is needed for a group of four people.

In case of each person gets [tex]\frac{2}{3}[/tex] cup of juice.

1 person gets cup of juice = [tex]\frac{2}{3}[/tex]

4 persons gets cup of juice = [tex]\frac{2}{3}\times4=\frac{8}{3} =2\frac{2}{3} \ cups\ of \ juice[/tex]

Thus, [tex]2\frac{2}{3}[/tex] cups of tomato juice is needed if they each get [tex]\frac{2}{3}[/tex] cup of juice.

Final answer:

To compute the needed tomato juice for four people with varying cup quantities, multiply the cup amount by the number of people.

Explanation:

To find out how much tomato juice is needed for four people if each person gets 1/3 cup, you would multiply 1/3 cup by 4 people:

1/3 cup x 4 people = 4/3 = 1 1/3 cups of tomato juice

If each person gets 2/3 cup of juice, you would multiply 2/3 cup by 4 people:

2/3 cup x 4 people = 8/3 = 2 2/3 cups of tomato juice

The first term of the geometric sequence is

[tex]a_1 =5[/tex].

The common ratio between the consecutive terms is

[tex]\dfrac{20}{5} = 4,[/tex]

[tex]\dfrac{80}{20} = 4;[/tex]

therefore, we see that the nth term is found by

[tex]a_n =4 a_{n-1}[/tex]

Thus, the recursive formula for the geometric sequence is

[tex]a_1 = 5,\\a_n =4 a_{n-1}.[/tex]

Final answer:

The recursive formula for finding the nth term of a geometric sequence is a_n = a_1 * r^(n-1), where a_n represents the nth term, a_1 is the first term, and r is the common ratio. In this case, the given sequence is 5, 20, 80. The recursive formula for this sequence is a_1 = 5 and a_n = 4 * a_(n-1).

Explanation:

The recursive formula for finding the nth term of a geometric sequence is given by: an = a1 * r(n-1) where an represents the nth term, a1 is the first term, and r is the common ratio. In this case, the given sequence is 5, 20, 80, ...

Since the first term is 5, and the common ratio between terms is 4, the recursive formula for this sequence is: a1 = 5 and an = 4 * an-1.

Consider two representations. Representation A is abstract and bears no systematic relationship to what it represents, whereas Representation B shares some features of what it represents. Representation A is a(n) ________ and Representation B is a(n) ________.

Answers

Answer:

Consider two representations. Representation A is abstract and bears no systematic relationship to what it represents, whereas Representation B shares some features of what it represents. Representation A is a **symbolic representation** and Representation B is an **analogical representation**.

Step-by-step explanation:

Symbolic representation as it sounds, uses visual symbols to represent variable/data. This form of representation doesn't need an explanation or a relationship between the symbol and what it is representing. There are numerous examples of these all over Mathematics and Physics. For example, Angular speed is represented by ω; there isn't a direct relationship between ω and angular speed. We have just come to accept that the symbol, ω, stands for angular speed.

Analogical representation hold some of the actual characteristics of what they represent. One can tell much about what is being represented just by looking at the analogical representation.

Pictures, graphs, Maps etc., are great examples of analogical representations.

The opposite sides of a rectangular are congruentThe opposite angles of a rectangular are congruentThe area of a rectangular is (length×breadth)The perimeter of a rectangular is 2(length+breadth)

Given

The perimeter of the fence is 68 feet

The area of the rectangular yard is 240 square feet

Let the length be x feet and breadth is y feet

According to the problem,

2(length+breadth)=68

⇒2(x+y)=68

⇒[tex](x+y)=\frac{68}{2}[/tex]

[tex]\Rightarrow x+y=34[/tex] .......(1)

The area of the rectangular is

length×breadth=240

⇒x×y=240

[tex]\Rightarrow x=\frac{240}{y}[/tex]

Putting the value x in the equation

[tex]\frac{240}{y}+y=34[/tex]

[tex]\Rightarrow \frac{240+y^2}{y}=34[/tex]

[tex]\Rightarrow 240+y^2=34y[/tex]

⇒y²-24y-10y+240=0

⇒y(y-24)-10(y-24)=0

⇒(y-24)(y-10)=0

⇒y=24,10

When, y=24

[tex]x=\frac{240}{24}=10[/tex]

Answer:

y = 7 csc(½ x) − 2

Step-by-step explanation:

General form of a cosecant function is:

y = A csc(2π/T x + B) + C

where A is the amplitude, T is the period, B is the horizontal offset ("phase shift"), and C is the vertical offset ("midline").

The range is (-∞, -9] [5, ∞), so the midline is halfway between -9 and 5.

C = (-9 + 5) / 2

C = -2

The amplitude is half the difference between -9 and 5.

A = |-9 − 5| / 2

A = 7

The period is twice the distance between consecutive asymptotes.

T = 2 (2π − 0)

T = 4π

So far, we have:

y = 7 csc(½ x + B) − 2

We know there is an asymptote at x = 0.  Cosecant is undefined at multiples of π, so:

½ (0) + B = kπ

B = kπ

B is any multiple of π.  The simplest choice is B = 0.

y = 7 csc(½ x) − 2

Answer:

P[X=3,Y=3] = 0.0416

Step-by-step explanation:

Solution:

- X is the RV denoting the no. of customers in line.

- Y is the sum of Customers C.

- Where no. of Customers C's to be summed is equal to the X value.

- Since both events are independent we have:

                         P[X=3,Y=3] = P[X=3]*P[Y=3/X=3]

              P[X=3].P[Y=3/X=3] = P[X=3]*P[C1+C2+C3=3/X=3]

        P[X=3]*P[C1+C2+C3=3/X=3] = P[X=3]*P[C1=1,C2=1,C3=1]        

              P[X=3]*P[C1=1,C2=1,C3=1]  = P[X=3]*(P[C=1]^3)

- Thus, we have:

                        P[X=3,Y=3] = P[X=3]*(P[C=1]^3) = 0.25*(0.55)^3

                        P[X=3,Y=3] = 0.0416

Answers

Final answer:

An appeal to authority is using an expert's statement to support a conclusion, which is valid when the statement is within the expert's field. The authority should be able to provide support for the claim, and the appeal should not be based on the authority's position alone. The fallacy of false authority arises when an individual is not actually an expert in the subject matter they are discussing.

Explanation:

The term appeal to authority or argumentum ad verecundiam involves using the statement of an expert to support a conclusion. However, not every appeal to an authority is valid. A key point is that the statement must fall within the expert's range of expertise. For example, a Nobel Laureate in Economics would not be a qualified authority on medical issues unless their advice pertains to economic factors of medicine.

An argument from authority becomes fallacious when the cited authority is not an expert in the relevant field. Moreover, the authority's position should not be the sole foundation for a conclusion; the authority must be able to provide independent support for the conclusion. When an appeal to authority is appropriate, it means that the person being cited is a recognized expert and is knowledgeable and credible in the area under discussion, such as a doctor when it comes to medical issues or a lawyer in legal matters.

The frequency of red light is about 4.3 x 10^14 Hz. The frequency of violet light is about 7.5 x 10^14 Hz. What is the approximate difference in frequency between red light and violet light?

Answers

Answer:

The difference in frequency between red light and violet light is 3.2×10¹⁴Hz.

Step-by-step explanation:

Frequency :During any time interval the number of waves which pass through a point in space is known as frequency of that ray.

The unit of frequency is Hz.

There are 7 colors in white ray. The highest frequency color is violet and lowest frequency color is red.

Given that the frequency of red is 4.3 ×10¹⁴Hz.

The frequency of violet ray is 7.5×10¹⁴Hz.

The difference in frequency between red light and violet light is

=(7.5×10¹⁴-4.3×10¹⁴)Hz

=(7.5-4.3)×10¹⁴Hz.

=3.2×10¹⁴Hz.

Final answer:

The difference in frequency between red light and violet light is found by subtracting the frequency of the red light from that of the violet light. The resulting difference is approximately 3.2 x 10^14 Hz.

Explanation:

The frequency of light is a measurement of how many waves pass a point in a given period of time. To find the difference in frequency between the red light and the violet light, we need to subtract the frequency of the red light from the frequency of the violet light.

The frequency of violet light is 7.5 x 1014 Hz, while the frequency of red light is 4.3 x 1014 Hz. To calculate the difference, we subtract these two frequencies as follows:

7.5 x 1014 Hz - 4.3 x 1014 Hz = 3.2 x 1014 Hz

Therefore, the approximate difference in frequency between red light and violet light is 3.2 x 1014 Hz.

An engineer designs a new cargo ship to transport 12,000 standard shipping containers. The ship's cargo hold and a shipping container are similar rectangular prisms. A standard shipping container is 6 meters long, 2.5 m wide, and 2.5 m tall.

What is the volume of the cargo hold of the ship?

Answers

Answer:

Vol=[tex]450,000m^3[/tex]

Step-by-step explanation:

Volume of rectangular prism is obtained using the formula:

[tex]V=whl\\w-width\\h-height\\l-length[/tex]

Dimensions of shipping containers is given as:

[tex]w=2.5m\\h=2.5m\\l=6m\\[/tex]

To obtain the volume of the cargo ship, we need to calculate the volume of 1 unit of a shipping container then multiply it by the number of containers the ship can carry.

let n be the number of containers ship can carry.

[tex]V_c=whl\\V_c=2.5m\times2.5m\times6m\\V_c=37.5m^3\\[/tex]

Volume of ship,[tex]V_s[/tex]

[tex]V_s=nV_c[/tex]

But n=12000

[tex]V_s=12000\times37.5m^3\\=450,000m^3[/tex]

Step-by-step explanation:

Suppose that f and g are two functions with the same domain. If ​f(x)equals​g(x) for every x in the​ domain, the equation is called​ a(n) _______.​ Otherwise, it is called​ a(n) _______ equation.

Answers

Answer:

Identity; conditional

Explanation:

Identity functions are functions that returns the SAME value which was used in its argument. In this case, f(x) = g(x). Therefore f(x) = g(x) = x.

Conditional functions are conditions that evaluates the condition and returns DIFFERENT values all depending on the condition value. That is, in this case, f(x) is not equal to g(x) for every x domain.

So, while identity functions returns the same value, conditional functions returns different functions.

Final answer:

An equation where f(x) equals g(x) for every x in the domain is an identity equation; otherwise, it's a conditional equation. For f(x) = x² and g(s) = s², they are the same function. Function f can be expressed in terms of y if g is invertible.

Explanation:

If f(x) equals g(x) for every x in the domain, the equation is called an identity. Otherwise, it is called a conditional equation.

For the given functions f(x) = x² and g(s) = s², we can see that they are indeed the same function, as they both satisfy the vertical-line test and map every x in the domain to a unique y in the range.

In the context of variable transformations, if y = g(x) defines a transformation from x to y, we could describe function f(x) in terms of the variable y only if there is a way to express x in terms of y. If g is invertible, then we can write f as a function of y by finding g⁻¹(y) and then applying f to it, yielding f(g⁻¹(y)).
