possible?
Answers
Answer:

Women (Applicants): 6
Job Positions: 5
Man = 3
Women = 2
Required:
Number of possible outcomes
This question represent selection; i.e. selecting candidates for job positions;
This question can be solved by using Permutations/Selection formula
Given that 3 man are to be selected from 14 men and 2 women from a total of 6 women
Let M represent Men and W represent Woman
Number of ways = M + W
Calculating M
[tex]M = nPr[/tex]
Substitute nPr with its formular
[tex]M = \frac{n!}{(n-r)!}[/tex]
Where n = 14 men and r = 3 applied
[tex]M = \frac{14!}{(14 - 3)!}[/tex]
[tex]M = \frac{14!}{11!}[/tex]
[tex]M = \frac{14*13*12*11!}{11!}[/tex]
[tex]M = 14*13*12[/tex]
[tex]M = 2184[/tex]
Calculating W
[tex]W = nPr[/tex]
Substitute nPr with its formula
[tex]W = \frac{n!}{(n-r)!}[/tex]
Where n = 6 men and r = 2 applied
[tex]W = \frac{6!}{(6-2)!}[/tex]
[tex]W = \frac{6!}{2!}[/tex]
[tex]W = \frac{6*5*4*3!}{2!}[/tex]
[tex]W = 6*5*4[/tex]
[tex]W = 120[/tex]
Recall that Number of ways = M + W
Number of Ways = 2184 + 123
Number of Ways = 2307
Which of the following is a true proportion of the figure based on the triangle proportionality theorem? answers: A) ab= dc B) ac=ad C) ab=ac D) bd=ca
Answers
Answer:
A) a/b = d/c
Step-by-step explanation:
The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally.
In this case, line TU is parallel to side QR. So, the ratios a:b and d:c are equal. In other words, a/b = d/c

X degree= ? Degree
(X+50) Degree =? Degree
(180-3x) Degree =? Degree
(Simplify your answers. Type an integer or a fraction.)
Answers
Answer:
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Step-by-step explanation:
In a triangle, the sum of all inside angles must be 180 degrees.
In this question:
The inside angles are: x, x + 50 and 180 - 3x.
Then
x + x + 50 + 180 - 3x = 180
2x - 3x = -50
x = 50
So
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

45% of a 300ml drink is concentrated pineapple juice. The rest is water. Find the volune of water that must be added so that 40% of the drink is concentrated pineapple juice.
Answers
Answer:
37.5 mL
Step-by-step explanation:
If x is the volume of water, then:
(0.45)(300) + (0)(x) = (0.40)(300 + x)
135 = 120 + 0.40x
15 = 0.40x
x = 37.5
The volume of water that must be added so that 40% of the drink is concentrated pineapple juice will be 37.5 mL.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given;
45% of a 300ml drink is concentrated pineapple juice.
If x is the volume of water, then we get;
(0.45)(300) + (0)(x) = (0.40)(300 + x)
135 = 120 + 0.40x
15 = 0.40x
x = 37.5
Hence, The volume of water that must be added so that 40% of the drink is concentrated pineapple juice will be 37.5 mL.

28. Find the area of the triangle ABD in the diagram below.
Answers
Answer:
A = 60 cm²
Step-by-step explanation:
Finding BC using Pythagorean Theorem:
=> [tex]c^2= a^2+b^2[/tex]
=> [tex]13^2 = a^2+5^2[/tex]
=> 169-25 = [tex]a^2[/tex]
=> [tex]a^2[/tex] = 144
Taking sqrt on both sides
=> BC = 12
So,
BC = CD = 12
=> BD = BC+CD
=> BD = 12+12
=> BD = 24
Now, The area:
=> Area of a Triangle = [tex]\frac{1}{2} (Base)(Height)[/tex]
Where BASE = 24, HEIGHT = 5
=> A = 1/2(5)(24)
=> A = 1/2(120)
=> A = 60 cm²
Step-by-step explanation IN triangle abc,
AC² = AB² + BC² (Phythogoras theorem)
13² = 5² + BC²
169 - 25 = BC²
144 = BC²
BC² = 144
BC = 12 (APPLAYING SQAURE ROOT)
Then in triangle ADC,
AD² = AC² + CD²
AD² = 13² + 12² (CD = BD - BC)
AD² = 169 + 144
AD = 17cm (aprox.)
Therefore area of triangle abd = 1/2× length × side = 1/2× 5 ×24 = 5 × 12 = 60cm

The height of the prism is 8 meters. A triangular prism. The triangular base has a base of 10 meters and height of 9 meters. The height of the prism is 8 meters.
Answers
Answer: The correct answer is option 4;
A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Step-by-step explanation: A simple check for the result of each set of dimensions would give the correct answer.
The volume of a right triangular prism is derived as follows;
Volume = 1/2 * b * h * l
Where, b is the base of the triangle, h is the vertical height of the triangle and l is the length of the prism.
Note that the area of the right triangle is denoted by 1/2 * b * h, and multiplying this result by the length of the prism gives the entire depth or volume of the triangular prism. Let us examine the dimensions one after the other;
(1) A triangular prism. The triangular base has a base of 7 metres and height of 9 metres. The height of the prism is 6 metres.
Volume = 1/2 * 7 * 9 * 6
Volume = 189 cubic metres
(2) A triangular prism. The triangular base has a base of 6 metres and height of 13 metres. The height of the prism is 5 metres.
Volume = 1/2 * 6 * 13 * 5
Volume = 165 cubic metres
(3) A triangular prism. The triangular base has a base of 11 metres and a height of 8 metres. The height of the prism is 8 metres.
Volume = 1/2 * 11 * 8 * 8
Volume = 352 cubic metres
(4) A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Volume = 1/2 * 10 * 9 * 8
Volume = 360 cubic metres

A. 4.8cm B. 5.0cm C. 9.6cm
D. 48.0cm E. 2400.0cm
Answers
So do 480/50 = 9.6cm (our scale factor)
then 1x9.6 = 9.6cm
So the answer is C which is 9.6cm
Answer:
C. 9.6 cm
Step-by-step explanation:
This is all about unit rate. In this scenario the unit rate is 50/1 and for 480 km that fraction would be 480/x so we could either do cross multiplication or divide across the numerator and denominators. Let's divide. 480/50 is equal to 9.6. Seeing as that is what helped us get from numerator a to numerator b we would then multiply that in our denominators. So, 1*9.6 is equal to 9.6 so the amount of cm for 480 km is 9.6 cm.

What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Given:
While reflecting a point with coordinates as (x, y), over y axis, the rule followed is
(x, y) = (-x, y)
The given function is,
f(x) = x²
So, reflecting it over y axis, we have to replace x with -x
(x, f(x)) = (-x , f(x))
So, the new reflected function is
f(-x) = -x²

A certain club has $50$ people, and $4$ members are running for president. Each club member votes for one of the $4$ candidates. How many different possible vote totals are there?
Answers
Answer:
The number of different possible vote totals is 184.
Step-by-step explanation:
It is provided that there are N = 50 people in a club.
The position of President is open. And there are x = 4 members running for he post of President.
So, there are n = N - x = 50 - 4 = 46 people voting for these 4 members.
Each member of the club has x = 4 possible choices.
So, the number of different possible vote totals are:
Number of different possible votes = n × x
= 46 × 4
= 184
Thus, the number of different possible vote totals is 184.
