22.3 is correct i believe :)
Step-by-step explanation:
a committee of 4 is to be selected from a group of 9 women and 7 men. what is the probability that 2 men and 2 women are selected?
The probability of selecting 2 men and 2 women from a group of 9 women and 7 men is 11%.
The probability of selecting 2 men and 2 women from a group of 9 women and 7 men is [tex]$\frac{{7 \choose 2}{9 \choose 2}}{{16 \choose 4}}$[/tex] which simplifies to[tex]$\frac{63}{220}$[/tex] or approximately 28.6%. The probability of selecting 2 men and 2 women from a group of 9 women and 7 men is 11%.
The probability of selecting 2 men and 2 women from a group of 9 women and 7 men can be calculated by using the formula for combination, nCr. In this case, we would be selecting 4 people from 16 individuals, so n = 16 and r = 4. The formula is nCr = n!/(r!(n-r)!). This can be simplified to 16C4 = 16!/ (4!(12!)). The answer is 1820/21168, which can be simplified to 86/792, or approximately 11%. Therefore, the probability of selecting 2 men and 2 women from a group of 9 women and 7 men is 11%.

Mi use structure ji builds a right rectangular prism with 14-centimeter cubes in the bottom layer with no gaps or overlaps. if there are 8 layers, The volume of the right rectangular prism is 14 x 14 x 8 = 1,536 cm3.
To get this answer, I first determined the number of cubes in the bottom layer. Since the bottom layer contains 14 cubes, the total length of the base of the prism is 14 cm. The height of the prism is 8 layers, so the total height of the prism is 8 cm. To calculate the volume of a right rectangular prism, you need the base length, the width, and the height. Since all three of these measurements are given, the volume can be calculated by multiplying the base length (14 cm) by the width (14 cm) by the height (8 cm). The result is 1,536 cm3.

Which of the layer(s) in the diagram below have liquid-like properties? 3 3&4 1,2,3 & 4 2&4 1,2 & 4
The layers in the diagram that have liquid-like properties are layers 1,2,3 and 4. This is determined by the properties of liquids, which are: high viscosity, low compressibility, and the ability to flow.
Viscosity is the measure of a liquid's resistance to flow. It can be calculated using the formula η = (ΔP/l) x (d/Δt), where η is the viscosity, ΔP is the pressure difference, l is the length of the flow, d is the change in distance, and Δt is the time difference.
Compressibility is the measure of how a liquid responds to pressure or volume change. It is calculated using the formula β = -1/V (dV/dP), where β is the compressibility, V is the volume, and dV/dP is the change in volume over the change in pressure.
The ability to flow is the measure of how a liquid can move from one place to another. It is calculated using the formula Q = A x v, where Q is the flow, A is the area of the cross-section of the flow, and v is the velocity.
By using these formulas and calculations, it can be determined that layers 1,2,3, and 4 have liquid-like properties.

Which statement is true of table A and table B shown below?
Table A represents a function because there is only one output for
each input value.
Table B represents a function because there is only one output for
each input value.
Table A represents a function because there is only one input for each
output value.
Table B represents a function because there is only one input for each
output value.
Table A represents a function, but Table B does not represent a function.
What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
A function or mapping is described as a collection of pairs of x and y that are ordered such that given different values of x, there will also be different values of y or vice versa.
For instance, the function x=y+2 yields a different x for every different value of y, while yielding the same x value for every single different value of y.
We obtain two distinct x for two distinct ys, thus we can refer to this as a function at that point.
As, each element of X is associated with a unique element of Y, so this is a function.
Table A

As, each element of X is associated with a unique element of Y, so this is a function.

Answer:
We can use the trigonometric function sine to calculate the length of AB in a right-angled triangle.
The sine function relates the ratio of the side opposite an angle (in this case, AB) to the hypotenuse (AC) with the angle in question (in this case, angle C):
sin(C) = AB/AC
In this case, we know that angle C is 29 degrees and the hypotenuse AC is 5cm, so we can substitute these values into the equation to find AB:
sin(29) = AB/5
To solve for AB, we can multiply both sides of the equation by 5:
AB = 5sin(29)
AB=2.42cm
If x and y are in direct proportion and y is 18 when x is 9, find y when x is 5.
Answer:
y=10
Step-by-step explanation:
18/9=1/2
so
x/5=1/2
Answer: The value of y will be 10 when the value of x is 5.
x and y are directly proportional to each other so,we can write the given relation in mathematical form as:
y=kx
k is any constant
We are given: The value of y is 18 when value of x is 9:
x=9 and y=18
Putting the value of x and y in the above equation , we get:
18=9k
k=18/9=2
k=2
So now we have the proportional relation(k) between x and y.
Again,
we have been given the value of x=5 and we are asked the value of y using same proportional relation.
y=k(5)
y=2(5)=10
Hence the value of y the value of x is 10.

The columns of the matrix A span R2.
In order to determine if the columns of the matrix A span R2, we need to check if the columns of A can be used to generate all possible linear combinations of the form a1v1 + a2v2, where a1 and a2 are scalars and v1 and v2 are the columns of A.
A = [2 1]

The columns of A are [2, 0, -3] and [1, 1, -1]. To check if these columns span R2, we need to see if we can create any vector in R2 by taking linear combinations of the columns. We can see that by taking linear combinations of the columns, we can create any vector of the form (a, b) in R2.
For example, by taking a = 2, b = 1, we can generate the vector (2, 1) by taking
a[2, 0, -3] + b[1, 1]
And by taking a = 3, b = -1, we can generate the vector (3, -1) by taking

In the equations above, b and c represent the price per pound, in dollars, of beef and chicken, respectively, x weeks after July 1 during last summer. What was the price per pound of beef when it was equal to the price per pound of chicken?
The price per pound of beef when it was equal to the price of chicken is $3.35 per pound.
The following linear equations represent the costs of beef and chicken:
Beef price, B:
B = 2.35 + 0.25x
Price of chicken, C :
C = 1.75 + 0.40x
Where x in both equations denotes the number of weeks since July 1 of the previous summer:
B = 2.35 + 0.25x
Price of chicken, C :
C = 1.75 + 0.40x
Where x in both equations represents x weeks after July 1 of last summer
Firstly:
We identify the week when the cost of beef and chicken is equal:
Beef = Chicken
2.35 + 0.25x = 1.75 + 0.40x
We solve for x
2.35 - 1.75 = 0.40x - 0.25x
0.60 = 0.15x
x = 0.60 / 0.15
x = 4
Therefore, poultry and beef had the same price four weeks after July 1 of last summer.
B = 2.35 + 0.25(4)
B = 2.35 + 1
B = 3.35
When the price of chicken and beef were equal, the price per pound of meat was $3.35.

We may utilize the knowledge that the rectangle's perimeter is 112 and that its sides are 5x and 3x+5 to determine the value of x and the lengths of each side. We can put up the following equation because the perimeter of a rectangle is equal to the sum of its four sides:
2(5x) + 2(3x + 5) = 112
We must simplify and account for x in order to solve for x. We'll start by allocating the two on the left side of the equation:
10x + 6x + 10 = 112
We'll then mix similar terms:
16x + 10 = 112
To get x alone, we will now deduct 10 from both sides, giving us 16x = 102.
Next, multiply both sides by 16 times to get 6.375.
Therefore as a result, the rectangle's sides measure 5x = 5(6.375) = 31.875 inches and 3x+5 = 3(6.375) + 5 = 20.125 inches, respectively.
