b) ways to select 7 women.
c) The probability is 0.004662
What is Combination?Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.
a) Number of ways can seven people be selected from this group of thirteen
C( 13, 7)

To simplify a complex algebraic expression, you handle fractions first by bringing them to a common denominator. However, the resources provided seem misplaced as they pertain to calculus rules and Chemistry, which are not relevant to this algebra question.
Explanation:The student's question is asking to simplify a complex algebraic expression: 6/x-6+3x/x+5-1/(x-6)(x+5). To simplify such an expression, it's best to deal with fractions first. Note that the given expression can also be expressed as three separate fractions summed together, i.e., (6/x-6) + (3x/x+5) - [1/(x-6)(x+5)]. Dealing with fractions in simplification, we combine them to a common denominator and rationalize the numerator and denominator. After that, simplify the resulting expression. However, with provided reference, it seems that there is a misunderstanding or a misplacement of information because resources given are about calculus rules and Chemistry which are not relevant in simplifying this algebraic expression.

If A(0, 0), B(3, 3), C(9, 3), and D(6, 0) are the vertices of a quadrilateral, do the points form a parallelogram? Justify your answer.
A. Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals 1, and AB = DC = square root of 18.
B. Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals −1, and AD = CD = 3 units.
C. Yes, it is a parallelogram because the midpoint of the diagonals of segment AC and segment BD is (4.4, 1.5).
D. No, it is not a parallelogram because the slope of segment AB = 1 and the slope of segment DC = −1.

What are the zeros of f(x) = 4x^2 - 12x + 8 (I need a clear explanation on how to solve it)
The zero of the quadratic function is therefore x = 1. Since both factors give the same zero, we have a repeated zero and f(x) only touches the x-axis at one point, x = 1.
The zeros of the quadratic function f(x) = 4x^2 - 12x + 8 are the values of x that make f(x) = 0. In this function, we can factor by finding two numbers that multiply to give the constant term (8 times 4, the coefficient of x^2) and add to give the coefficient of x (-12). Here, those numbers are -4 and -4, so we rewrite the middle term -12x as -4x - 4x, and factor by grouping:
4x^2 - 4x - 4x + 8 = 0
4x(x - 1) - 4(x - 1) = 0
(4x - 4)(x - 1) = 0
Now we have two factors equal to zero, which gives us two equations to solve:
4x - 4 = 0 or x - 1 = 0
x = 1

b. 105
c. 1.05
d. 5
and the bank compounds the interest__ .
a. annually
b. continuously
c. daily
d. monthly
The balance of the account will grow __ .
a. logarithmically
b. exponentially
c. asymptotically
d. linearly
Answer:
The annual interest is,
Option d is correct
5%
The bank compounds the interest_
Option a is correct.
Annually.
The balance of the account will grow,
Option b is correct
exponentially
Step-by-step explanation:
Exponential growth function is given by:
[tex]y=(1+r)^x[/tex] .....[1]
where,
r is the annual interest in decimal
x is the number of periods.
As per the statement:
Consider the function:
[tex]y=(1.05)^{\frac{x}{12}}[/tex] where, x represents the time in months.
On comparing with [1] we have;
[tex]1+r = 1.05[/tex]
Subtract 1 from both sides we have;
r = 0.05 = 5%
The annual interest is, 5%
and
the bank compounds the interest annually.
The balance of the account will grow exponentially

Which of the functions below is the inverse of the logarithm function?
Linear function
Exponential function
Rational function
Radical function
Answer:
Option 2 - Exponential function
Step-by-step explanation:
To find : Which of the functions below is the inverse of the logarithm function?
Solution :
The inverse of a logarithmic function is an exponential function.
As by property of logarithmic,
[tex]y=\log_b(x)\\\Rightarrow x=y^b[/tex]
For example -
Taking log function,
[tex]y=\log_2 x[/tex]
Applying property it convert into exponential function,
[tex]x=2^y[/tex]
The graphs of the logarithmic function and the exponential function are mirror images of one another.
Therefore, Option 2 is correct.

Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation y=3.5x+4; a(...; 5), b(10; ...)
A(2/7:5)
B(10:39)
The slope is 7/2.
The slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation of line is y=3.5x+4
When we compare this with slope intercept form y=mx+b.
slope m=3.5
We need to find the value of x when y is 5
5=3.5x+4
1=3.5x
Divide both sides by 3.5
x=0.28
So a coordinates are (0.28, 5)
Now let us find y value when x is 10
y=3.5(10)+4
y=39
So b coordinates are (0.28, 39)
Hence, the slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)

Evaluate the function below for x = 2 F(x) = 4x3 - x2 - 5x + 7
Answer:
The value of the given function is 25 for x = 2.
Step-by-step explanation:
Given function is,
[tex]F(x) = 4x^3 - x^2 - 5x + 7[/tex]
At x = 2,
The value of the function is,
[tex]f(2)=4(2)^3-(2)^2-5(2)+7[/tex]
[tex]=4(8)-4-10+7[/tex]
[tex]=32 - 7[/tex]
[tex]=25[/tex]
Hence, the value of the given function is 25 for x = 2.
which statement can be proved if you are given that SK≌LR?
Answer:
C
Step-by-step explanation:
The correct answer is C.[tex]$\overline{SL}\cong\overline{KR}$[/tex]
Given that [tex]$\overline{SK}\cong\overline{LR}$[/tex] , we can see that triangle SKL is congruent to triangle LRP by the Side-Side-Side (SSS) congruence postulate. This means that all corresponding sides and angles of the two triangles are congruent.
Since [tex]$\overline{SK}\cong\overline{LR}$[/tex]is given, we know that [tex]$\overline{SL}\cong\overline{KR}$[/tex] must also be true. The other answer choices do not necessarily follow from the given information.
