In how many ways can a committee of two men and two women be formed from a group of nine men and nine women?
==========================================================
Explanation:
We have 9 men and we want to select 2 of them. The order doesn't matter. If order did matter, then we would have 9*8 = 72 permutations. Since order doesn't matter, we have instead 72/2 = 36 combinations. The reason why order doesn't matter is because no person outranks another on a committee. Any given seat is the same as anyone else. This is excluding any chairperson of course.
So we have 36 ways to select the men. There are also 36 ways to select the women as well for the exact same steps as listed above. This is due to there being 9 women total and we're selecting 2 of them.
Since there are 36 ways to select the two men, and 36 ways to select the two women, this leads to a total of 36*36 = 1296 different committees
It might help to think of a table that has 36 rows and 36 columns. Each row could represent a different two-person group of men while each column represents a different two-person group of women. The intersection of a given row and column would then form a unique four-person committee. So that may help visually show why there are 36*36 = 1296 different committees (each committee is an inner cell).

Write the equation of a line that is parallel to y=−5/4x+7
and that passes through the point (-4,1)
Answer:
y=-5/4x-4.
Step-by-step explanation:
parallel lines have to have the same slope so they don't intersect each other
original equation with the same slope and rewrite it using point slope form:
y-y1=-5/4(x-x1) now Substitute the point(-4,1)
y-1=-5/4(x-(-4))
y-1=-5/4(x+4)
Now we can distribute the -5/4 and add 1 to the right to get our final slope-intercept form:
y-1=-5/4x-5
y=-5/4x-4.
The parallel line of y=-5/4x+7 that passes through point (-4,1) is y=-5/4x-4.
Answer: y=-5/4x-4.

Determine the new price after following the markdown.
original price
$72.00
markdown
15%
Choices
•$61.20
•$62.50
•$61.85
•type equation here
Answer:
$61.20
Step-by-step explanation:
15% of 72 is 10.8 (because 72 x 0.15 = 10.8)
So, the markdown is $10.80 off of $72.00
To get the new sale price, we just subtract the markdown ($10.80) from the original price ($72.00)
$72.00 - $10.80 = $61.20
So, the answer is $61.20
I hope this helps! :)

Answer:
the surface area is not equal to 296 sq ft.
Step-by-step explanation:
There are total six faces of the given rectangular prism
Area of the top and bottom face is equal to 288 Sq ft
Area front face and the face at the back = 2 * 2 * 144 = 576 Sq. ft.
Area of the other two sides is = 2 * 2 * 144 = 576 Sq. ft.
The total surface area of the prism is 576 +576 + 288 = 1440 Sqft
No, the surface area is not equal to 296 sq ft.

The sum
of two numbers is 72. The difference is
22. Find the two numbers.
Answer:
b= 25
Step-by-step explanation:
a+b =72
a-b = 22
2a = 94
DBS(Divide Both Side) by 2
a = 47
=47 +b =72
and:
47 -b =22
subtract 47 from both sides:
b=25
and
-b = -25 MBS(Multiply Both Side) by-1 ....>b=25

Answer:
The volume of the triangular prism in the diagram is:
105.5 [tex]in^{3}[/tex]The surface area of the triangular prism in the diagram is:
10.75 [tex]in^{2}[/tex]Step-by-step explanation:
First, we're gonna calculate the surface area to obtain the volume, then, to calculate the area of a triangle (because the surface o a triangular prism is just a triangle), you can use the formula:
Area of a triangle = (base * height) / 2We have this data from the diagram, where the base of the triangles is 5 inches and, the height is 4.3 inches, replacing this in the formula:
Area of a triangle = ( 5 in * 4.3 in) / 2Area of a triangle = ( 21.5 [tex]in^{2}[/tex]) / 2Area of a triangle = 10.75 [tex]in^{2}[/tex]Now, we can calculate the volume of the triangular prism with the next formula:
Volume of a triangular prism = surface area * depthIn the diagram, we can see the depth is 14 inches, then:
Volume of a triangular prism = 10.75 [tex]in^{2}[/tex] * 14 inVolume of a triangular prism = 105.5 [tex]in^{3}[/tex]How you can see with the calculations perfomed, the surface area is 10.75 [tex]in^{2}[/tex] and the volume of that triangular prism is 105.5 [tex]in^{3}[/tex].

Answer:
f(5) = 2
Step-by-step explanation:
it says to use the function (-x+3) for when x is bigger than 2
f(x) = (-x) + 3 replace x with 5
f(5) = (-5) + 3 and f(5) = 2
Answer:
[tex]f(5)=-2[/tex]
Step-by-step explanation:
In piecewise functions, we need to find the applicable equation to use based on our value of [tex]x[/tex]. [tex]f(5)[/tex] denotes [tex]x[/tex] as 5. Since [tex]5>2[/tex], we will use the equation that corresponds to [tex]x>2[/tex], which is [tex]-x+3[/tex].

Answer:
y + 7 = 11/5(x + 9)Step-by-step explanation:
Given points:
(-9, -7) and (-4, 4)Find the slope:
m = (4 - (-7)) / (-4 - (-9)) = 11/5Use one of the points and point-slope form:
y - y1 = m(x - x2)y - (-7) = 11/5(x - (-9))y + 7 = 11/5(x + 9)Slope
m=(4+7)/-4+9m=11/5Equation in point slope form
