Answer:
a) 0.4545 = 45.45% probability that a random committee is made up of 2 women and 1 man.
b) 0.1515 = 15.15% probability that the Chairperson and Vice Chairperson are both women and the Treasurer is a man
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
If the order of the people chosen is important, we use the permutations formula. If the order is not important, we use the combinations formula.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
(a) What is the probability that a random committee is made up of 2 women and 1 man?
Order is not important, so we use the combinations formula.
Desired outcomes:
2 women from a set of 6, and a men from a set of 5. So
[tex]D = C_{6,2}*C_{5,1} = \frac{6!}{2!4!}*\frac{5!}{1!4!} = 15*5 = 75[/tex]
Total outcomes:
3 people from a set of 6 + 5 = 11. So
[tex]T = C_{11,3} = \frac{11!}{3!8!} = 165[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{75}{165} = 0.4545[/tex]
0.4545 = 45.45% probability that a random committee is made up of 2 women and 1 man.
(b) Suppose now that the committee consists of different positions: Chairperson, Vice-Chairperson, and Treasurer. What is the probability that the Chairperson and Vice Chairperson are both women and the Treasurer is a man?
Now, the order is important, which means that we use the permutations formula.
Desired outcomes:
2 women from a set of 6, and a men from a set of 5. So
[tex]D = P_{6,2}*P_{5,1} = \frac{6!}{4!}*\frac{5!}{4!} = 30*5 = 150[/tex]
Total outcomes:
3 people from a set of 11. So
[tex]T = P_{11,3} = \frac{11!}{8!} = 990[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{150}{990} = 0.1515[/tex]
0.1515 = 15.15% probability that the Chairperson and Vice Chairperson are both women and the Treasurer is a man

We have,
Based on the given transactions, we can prepare the accounting equation as follows:
a. Started business with Cash Rs. 250,000.
Assets: Cash = Rs. 250,000
b. Purchased goods amounting to Rs. 45,000 on credit from Harish.
Assets: Cash = Rs. 250,000, Inventory = Rs. 45,000
Liabilities: Accounts Payable = Rs. 45,000
c. Goods costing to Rs. 80,000 was sold for Rs. 1,25,000 on credit.
Assets: Cash = Rs. 250,000, Accounts Receivable = Rs. 1,25,000
Inventory: Rs. 45,000 - Rs. 80,000 = Rs. -35,000 (Assuming no additional purchases or returns)
Liabilities: Accounts Payable = Rs. 45,000
Capital: Retained Earnings = Rs. 1,25,000 - Rs. 80,000 = Rs. 45,000
d. Salaries outstanding Rs. 5,000.
Liabilities: Salaries Payable = Rs. 5,000
e. Rent paid Rs. 50,000.
Assets: Cash = Rs. 250,000 - Rs. 50,000 = Rs. 2,00,000
f. Withdrawn by owner for personal use Rs. 25,000.
Assets: Cash = Rs. 2,00,000 - Rs. 25,000 = Rs. 1,75,000
Capital: Retained Earnings = Rs. 45,000 - Rs. 25,000 = Rs. 20,000
Now, let's summarize the accounting equation:
Assets:
Cash = Rs. 1,75,000
Inventory = Rs. -35,000 (negative value indicates loss or returns)
Liabilities:
Accounts Payable = Rs. 45,000
Salaries Payable = Rs. 5,000
Capital:
Retained Earnings = Rs. 20,000
Therefore,
The accounting equation is:
Assets (Rs. 1,75,000 - Rs. 35,000) = Liabilities (Rs. 45,000 + Rs. 5,000) + Capital (Rs. 20,000)

Triangle ABC is the preimage of a transformation that consists of a reflection across x -axis followed by a reflection across the y -axis. Which of the triangles is the image of △ABC under this transformation? Select the triangle that corresponds to the image △A′B′C′ .
The image triangle △A'B'C' is formed by reflecting triangle ABC across the origin, resulting in each point's coordinates being negated.
The preimage triangle ABC undergoes a reflection across the x-axis followed by a reflection across the y-axis.
To determine the image triangle △A'B'C', we need to understand the effects of these transformations.
Reflection across the x-axis flips the points of the preimage vertically, while reflection across the y-axis flips the points horizontally.
When both reflections are applied successively, the resulting image will be a reflection across the origin (0,0).
Given that, the image triangle △A'B'C' will be the reflection of triangle ABC across the origin.
In this case, the x-coordinate and y-coordinate of each point in triangle ABC will be negated to obtain the corresponding point in △A'B'C'.
Let's consider the points of triangle ABC:
A(x₁, y₁), B(x₂, y₂), C(x₃, y₃)
To obtain the corresponding points in △A'B'C', we negate the x and y coordinates:
A'(-x₁, -y₁), B'(-x₂, -y₂), C'(-x₃, -y₃)
Therefore, the image triangle △A'B'C' is formed by reflecting triangle ABC across the origin, resulting in each point's coordinates being negated.
Note: It's important to note that without the actual coordinates of triangle ABC, it's not possible to determine the specific shape or size of the image triangle △A'B'C'.

(b) For the given augmented matrix, the system of equations is
-5x-6y-4z=400;
y+z=100;
-3x-3y-2z=150;
A "system-of-equations" is a set of two or more equations which contain multiple variables. The solution to the system of equations is the set of values for the variables that satisfy all the equations in the system.
An "Augmented-Matrix" is a way to represent a system of linear equations in a concise and organized manner. It is obtained by writing the coefficients of the variables and the constants in each equation in a rectangular array, with each row representing an equation.
Part(a) : The system-of-equations is given as :
x + 3r +0m = 150
0x + r + 0m = 250
-x - r + m = 400,
We see that the first column of the matrix will have 1, 0, -1,
the second-column will have 3, 1, -1 ;
the third-column will have 0, 0, 1.
So, the Augmented Matrix is represented as : [tex]\left[\begin{array}{cccc}1&3&0&150\\0&1&0&250\\-1&-1&1&400\end{array}\right][/tex].

In this matrix, the terms in the "first-column" will be multiplied by variable"x";
the terms in the "second-column" will be multiplied by variable"y"; and
the terms in the "third-column" will be multiplied by variable"z";
The term sin the "fourth-column" represents the output value.
So, "system-of-equation" will be represented as : -5x - 6y - 4z = 400;
0x + y + z = 100;
-3x - 3y - 2z = 150.

The maximum density of killer whales per cubic foot is 0.000021142, You must explain your answer using words, and you must show all work and calculations to receive credit.
The volume of the quarter-sphere tank is approximately 1,387,244 cubic feet.
The volume of tank 1 is 353h cubic feet, and the volume of tank 2 is 31,416 cubic feet.
The main tank is in the shape of a quarter-sphere, which means it is a quarter of a full sphere.
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere.
Given that the radius of the main tank is 95 feet
we can substitute this value into the formula to calculate the volume:
V = (4/3)π(95³) = 1,387,244 cubic feet.
The holding tanks are in the shape of cylinders that have been cut in half vertically.
The volume of a cylinder is given by the formula V = πr²h, where r is the radius of the base and h is the height.
For tank 1, the radius is given as 15 feet. Since it is a half-cylinder, we divide the volume by 2:
V1 = (1/2)π(15²)h = 353h cubic feet.
For tank 2, the height is given as 120 feet.
V2 = (1/2)π(15²)(120) = 31,416 cubic feet.
The maximum density is 0.000021142 killer whales per cubic foot
we can calculate the maximum number of killer whales as follows:
Number of killer whales = (Volume of main show tank) / (Density of killer whales)
Number of killer whales = 1,387,244 / 0.000021142 ≈ 65,606,197.
Therefore, the maximum number of killer whales allowed in the main show tank at any given time is 65,606,197

John borrowed $4,300.00 for 8 days at an annual simple interest rate of 13.75%. What is the amount of interest will John have to pay at the end of the loan?
John will have to pay $12.24 in interest at the end of the loan.
To calculate the amount of interest John will have to pay at the end of the loan, we can use the formula for simple interest:
Interest = Principal * Rate * Time
Given:
Principal (P) = $4,300.00
Rate (R) = 13.75% per annum
Time (T) = 8 days
First, we need to convert the rate from an annual percentage to a daily rate. Since there are 365 days in a year:
Daily Rate = (Rate / 100) / 365 = (13.75 / 100) / 365 = 0.0003767
Now we can calculate the interest:
Interest = Principal * Rate * Time
= $4,300.00 * 0.0003767 * 8
= $12.24
Therefore, John will have to pay $12.24 in interest at the end of the loan.

You have $400,000 saved for retirement. Your account earns 10% interest. How much will you be able to pull out each month, if you want to be able to take withdrawals for 20 years?
You will be able to withdraw $3,548.50 per month for 20 years if you have $400,000 saved for retirement and earn 10% interest.
To calculate the monthly withdrawals for a given time period, we can use the present value annuity formula. This formula allows us to calculate the fixed monthly withdrawal amount needed to deplete a given initial amount (in this case, $400,000) over a specified time period (20 years) at a given interest rate (10%).
The formula for present value annuity is:
PMT = PV * r / (1 - (1 + r)⁻ⁿ)
Where:
PMT = the fixed monthly withdrawal amount
PV = the present value of the initial investment ($400,000)
r = the interest rate per month (10%/12 = 0.00833)
n = the total number of monthly withdrawals (20 years * 12 months per year = 240)
Plugging in the values, we get:
PMT = 400,000 * 0.00833 / (1 - (1 + 0.00833)⁻²⁴⁰) = $3,548.50 (rounded to the nearest cent)

Find the surface area of the composite solid to the nearest hundredth.
A composite solid of a square prism with a square pyramid extending from the top and bottom face of the prism. The width, length, and height of the prism are all 5 inches. The slant height of the pyramid on the bottom of the prism is 7.5 inches. The height of the pyramid on top of the prisim is 3 inches.
The surface area of the composite solid is 255 square inches.
How to find the surface area of the composite solid?We will compute the surface area of each component and then add them together to find the surface area of the composite solid.
First, the surface area of the square prism:
Given: The square prism has a width, length, and height of 5 inches each.
Formula for the surface area of a rectangular prism: 2lw + 2lh + 2wh
Surface area of the prism = 2(5 * 5) + 2(5 * 5) + 2(5 * 5)
= 2(25) + 2(25) + 2(25)
= 50 + 50 + 50
= 150 square inches
Next, the surface area of the square pyramid at the bottom:
Given: The slant height of the pyramid on the bottom of the prism = 7.5 inches.
The base of the pyramid is a square with a side length of 5 inches.
Formula to find the lateral surface area of a square pyramid: (perimeter of base) * slant height / 2.
The base is a square, the perimeter is 4 times the side length.
Lateral surface area of the bottom pyramid = (4 * 5) * 7.5 / 2
= 20 * 7.5 / 2
= 150 / 2
= 75 square inches
Then, the Surface area of the square pyramid at the top:
Given: The height of the pyramid on top of the prism = 3 inches.
The base of the pyramid is a square with a side length of 5 inches.
Lateral surface area of the top pyramid = (4 * 5) * 3 / 2
= 20 * 3 / 2
= 60 / 2
= 30 square inches
Finally, we shall find the total surface area by summing up the surface areas of each component in this way:
Total surface area = Surface area of the prism + Surface area of the bottom pyramid + Surface area of the top pyramid
= 150 + 75 + 30
= 255 square inches
Therefore, the surface area of the composite solid = 255 square inches.

A survey of 800 nurses yielded the following information. 555 were health club members, 430 were smokers, and 320 of the health club members were smokers. How many of the 800 surveyed nurses were health club members or were smokers
Step-by-step explanation:
800 in total.
555 health club members.
430 smokers.
320 health club members (that means out of the total of 555) were smokers.
that means that
555 - 320 = 235 health club members were not smokers.
and out of the 430 smokers 320 were also health club members.
that means that
430 - 320 = 110 smokers were not health club members.
the question how many were health club members or smokers means how many people were either health club members or smokers.
so, we need to combine the sets of health club members and smokers.
the number of elements in the resulting set is not just the sum of elements of both sets, because some elements are in both sets and would be counted twice.
therefore, we have a few alternatives :
1. add both sets and then subtract the common part (people being in both sets), as this removes the double counting :
555 + 430 - 320 = 665
2. start with the common part (people that are in both sets) and add the extra people in both sets (health club members that do not smoke, and smokers that are not health club members) :
320 + 235 + 110 = 665
3. start with one of the full sets (e.g. all health club members) and add the extra people of the other set (all smokers that are not also health club members) :
555 + 110 = 665
or all smokers plus all health club members that were not smokers :
430 + 235 = 665
as you can see, as expected, the answer is always the same :
out of the 800 nurses 665 were health club members or smokers.

A cube has a depth of 9 dm. What is the volume of the cube?
The volume of the cube is 729 dm³
How to find the volume of the cube?Remember that all the dimensions on a cube are the same ones, then we have:
Length = Width = Depth.
And for any prism, the volume is the product between the 3 dimensions, then for any cube the volume is:
V = Length*Width*Depth.
In this case we know that the depth is 9dm, then also is the length and the width, and thus, the volume of this cube is:
V = 9dm*9dm*9dm = 729 dm³

The value of c in the polynomial is - 7.
How to solve polynomials?The polynomial is given as follows:
p(x) = 2x³ - x² + cx + 2 . The value of c if x - 2 is a factor of p(x) can be computed as follows:
Therefore,
p(x) = 2x³ - x² + cx + 2
when x - 2 is a factor, p(x) = 0
Therefore,
0 = 2x³ - x² + cx + 2
Hence,
2(2)³ - (2)² + 2c + 2 = 0
16 - 4 + 2c + 2 = 0
12 + 2 + 2c = 0
2c = - 14
divide both sides by 2
c = - 14 / 2
c = - 7
Therefore,
c = -7

need help please
This is a basic arithmetic problem and the solution to 9.7/0.0268 is equal to 361.94
Understanding Basic Arithmetic OperationBasic Arithmetic Operations are fundamental to solving mathematical problems and they are addition (+), subtraction (-), multiplication (×) and division (÷).
1. Addition:
Addition is the process of combining two or more numbers to find their total or sum. The symbol used for addition is "+". For example, to add the numbers 3 and 5, you write it as:
3 + 5 = 8
Here, 3 and 5 are added together to get the sum, which is 8.
2. Subtraction:
Subtraction is the process of finding the difference between two numbers. The symbol used for subtraction is "-". For example, to subtract 5 from 8, you write it as:
8 - 5 = 3
Here, 5 is subtracted from 8 to get the difference, which is 3.
3. Multiplication:
Multiplication is the process of repeated addition or combining equal groups. The symbol used for multiplication is "×" or "*". For example, to multiply 4 and 6, you write it as:
4 × 6 = 24
Here, 4 is multiplied by 6 to get the product, which is 24.
4. Division:
Division is the process of dividing a number into equal parts or finding how many times one number is contained within another. The symbol used for division is "÷" or "/". For example, to divide 20 by 5, you write it as:
20 ÷ 5 = 4
Here, 20 is divided by 5 to get the quotient, which is 4.
