Answer:
495 ways
Step-by-step explanation:
Given that:
Total number of applicants (n) = 12
Required number (r) = 4
Using the combination formula :
nCr = n! / (n-r)!r!
12C4 = 12! / (12 - 4)!4!
12C4 = 12! / 8!4!
12C4 = (12*11*10*9) / 4*3*2*1
12C4 = 11880 / 24
= 495 ways

I don't have any knowledge in algebra, so what would be the best way to learn it. (The only advancements I have within are things as 2+x=14 ***When x=12***)
Answer
I guess the best way to learn algebra is first being confident with your arithmetic and PEMDAS/BODMAS, then understanding how substitution works, knowing what like-terms, binomial products, squares, etc are and going through worked examples as well as solving algebraic problems yourself. Of course, to get a grasp on algebra, you should start from the basics and continue working your way up. You should be able to find resources online to help you.
Good luck!

You want to know the opinions of drivers with valid licenses across America on the issue of establishing a law that requires individuals to take and pass another driver's test at the age of 65 to determine whether they may retain their license. You obtain a list of all licensed drivers and mail a survey to a random sample of 10,000 drivers. Of those, 6,457 responded and 46% say they favor the test. Which of the following statements is true? (5 points)
A. Because random sampling is used, we can feel confident that the percentage of all
drivers with a valid license who say they favor the test is close to 46%.
B. The results of this survey may be affected by nonresponse bias.
C. We cannot trust these results because the survey was mailed. Only survey results
from face-to-face interviews are considered valid.
D. Because more than half of those who were mailed the survey actually responded,
we can feel fairly confident that the actual percentage of all drivers with a valid
license who say they favor another test is close to 46%.

The results of this survey may be affected by nonresponse bias

What is the slope-intercept form of the equation of the line that passes through the point (-6,1), and is perpendicular to the graph of 2x + 3y = -5
Answer:
Y= -3/2x-8
Step-by-step explanation:
Graph 8x−4y=16. From Big Ideas Math
Solve for y.
8x−4y=16
-4y = -8x + 16
y = (-8x + 16)/-4
y = (-8x)/-4 + (16/-4)
y = 2x - 4
We only need two points to graph linear equations.
Now let x be 0 and solve for y.
y = 2(0) - 4
y = -4
This leads to the point (0, -4).
We need another point.
Let y = 0 and solve for x.
0 = 2x - 4
4 = 2x
4/2 = x
2 = x
This leads to the point (2,0).
Plot these two points on the xy-plane and connect the points with a straight line.
I'll let you do that.

What method can be used to prove the triangles below are congruent
Answer:
SSS?Step-by-step explanation:
I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.

What are the zeros or x-intercepts of the parabola?
A) (0, -1) and (0,5)
B (2,0) and (-9,0)
C (-1,0) and (5,0)
D (0,-5) and (-5,0)
Answer:
C
Step-by-step explanation:
x-intercepts , when y=0 are
(-1,0) and (5,0)
Answer:
C
Step-by-step explanation:
The zeros are also known as x-intercepts so it is the points on the x axis.
For x-intercepts the y is 0 so it is (-1,0) and (5,0)

Solve the system of equation. Write the solution as a coordinate point
Answer:
(2,16)
Step-by-step explanation:
y=-x+18
y=8x
8x=-x+18
8x+x=9x
-x+x=0
9x=18
9x/9=x
18/9=2
x=2
y=8(2)
y=16
Answer:
(2,16)
Step-by-step explanation:
Step 1: Substitute -x+18 for y in y=8x:
-x+18=8x Add X to both sides
9x=18 Divide 9 by both sides
x=2
y=8(2)Plug in the new value for x(which is 2) into one of the equations
y=16

The ratio of a to 5 equals b
What do we do here? Tell me in the comments, please!
The value of a for the ratio a:b = 5 will be 25.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio of a to 5 equals b. When b = 5 the value of 'a' will be calculated as below,
a / 5 = b
a / 5 = 5
a = 5 x 5
a = 25
Hence, the value of 'a' will be 25.

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area

What is the correct factorization of:
x? - 11x + 18
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)
Solve for x: x2 = 16
Answer:
8
Step-by-step explanation:
to get x alone you divide the 2 away on both sides, getting x = 8. To check multiply 8 by 2 and you get 16.
Hope this helps!
Take the root of both sides and solve.
x = 4, −4
