Answer:
The three integers whose three times the sum of three consecutive integers is 72 will be: 7, 8, 9
Step-by-step explanation:
Let x, y, and z be the three consecutive integers
The sum of x, y, and z will be: x+y+z
The three times the sum of three consecutive integers is 72.
so the equation becomes:
3(x+y+z)=72
Now, putting x = 7, y=8 and z=9 in the L.H.S equation to check
3(x+y+z)
⇒ 3(7+8+9)
⇒ 3(24)
⇒ 72
Therefore, it is clear that the three integers whose three times the sum of three consecutive integers is 72 will be: 7, 8, 9

It is possible for two line segments to not intersect and also not be considered parallel.
true or false?
Oh yeah definitely, two lines don't have to be parallel or intersect. There are many examples. I'll give you one. Imagine two lines right now, one is flat horizontal, 180 degrees. Another line is above the horizontal line, at like 30 degrees. But they do not touch. So therefore, these lines are neither parallel or intersecting. The answer is true.

What is the affect on the graph of the linear parent function f(x) equals X when FX is replaced by FX +3
Answer:
The graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
Step-by-step explanation:
We know that when we add a constant to the input of the parent function, we get a horizontal shift.
The direction of shifting depends upon the value of the added constantly. If the added constant is negative, the shift of the graph will be left and if the added constant is positive, the shift of the graph will be right.
For example, consider the function
f(x)
so adding \(3\) in the put i.e. \(f(x+3)\) would be a change on the inside of the function, giving a horizontal shift left by 3.
Therefore, the graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).

Answer:
3.Injective
4. As the name suggests Invertible means “inverse“, Invertible function means the inverse of the function. Inverse functions, in the most general sense, are functions that “ reverse ” each other. For example, if f takes a to b, then the inverse, f -1, must take b to a. The inverse of a function is denoted by f-1
5. The graph of the inverse of a function reflects two things, one is the function and second is the inverse of the function, over the line y = x. This line in the graph passes through the origin and has slope value 1. It can be represented as; y = f -1 (x)
6. The horizontal line test is a convenient method that can determine whether a given function has an inverse, but more importantly to find out if the inverse is also a function. We say this function passes the horizontal line test.
7. When given a function, draw horizontal lines along with the coordinate system.
Check if the horizontal lines can pass through two points.
If the horizontal lines pass through only one point throughout the graph, the function is a one to one function.
Step-by-step explanation:
3. To have an inverse, a function must be injective i.e one-one. Now, I believe the function must be surjective i.e. onto, to have an inverse, since if it is not surjective, the function's inverse's domain will have some elements left out which are not mapped to any element in the range of the function's inverse.
4. As the name suggests Invertible means “inverse“, Invertible function means the inverse of the function. Inverse functions, in the most general sense, are functions that “reverse” each other. For example, if f takes a to b, then the inverse, f-1, must take b to a. In other words, we can define as, If f is a function the set of ordered pairs obtained by interchanging the first and second coordinates of each ordered pair in f is called the inverse of f. Let’s understand this with the help of an example.
5. An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1. One should not confuse (-1) with exponent or reciprocal here.
If f and g are inverse functions, then f(x) = y if and only if g(y) = x
In trigonometry, the inverse sine function is used to find the measure of angle for which sine function generated the value. For example, sin-1(1) = sin-1(sin 90) = 90 degrees. Hence, sin 90 degrees is equal to 1. A function accepts values, performs particular operations on these values and generates an output. The inverse function agrees with the resultant, operates and reaches back to the original function.
The inverse function returns the original value for which a function gave the output.
If you consider functions, f and g are inverse, f(g(x)) = g(f(x)) = x. A function that consists of its inverse fetches the original value.
Example: f(x) = 2x + 5 = y
Then, g(y) = (y-5)/2 = x is the inverse of f(x).
Note:
The relation, developed when the independent variable is interchanged with the variable which is dependent on a specified equation and this inverse may or may not be a function.
If the inverse of a function is itself, then it is known as inverse function, denoted by f-1(x).
6. In mathematics, the horizontal line test is a test used to determine whether a function is injective (i.e., one-to-one).
7. One-to-One Function. A function for which every element of the range of the function corresponds to exactly one element of the domain. One-to-one is often written 1-1. Note: y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test.

Find the length of AN given the figure below:
Applying the two-tangent theorem, the length of AN is: 21 units.
What is the Two-Tangent Theorem?The two-tangent theorem is a geometric theorem that states that if two tangents are drawn to a circle from a point outside the circle, then the lengths of the tangent segments are equal. This theorem is often used in geometry to find the length of tangent segments and to prove the existence of tangents to circles.
More formally, the two-tangent theorem states that if P is a point outside a circle with center O, and if PA and PB are tangents to the circle from point P, then PA = PB. In other words, the lengths of the two tangent segments are equal.
From the image above, AM and AN are two tangents from the same circle. Also, AN is also tangent with 29 - 2y.
This implies that the three tangents are congruent. Therefore:
6y - 3 = 29 - 2y
6y + 2y = 29 + 3
8y = 32
y = 32/8
y = 4
AN = 6y - 3
Plug in the value of y
AN = 6(4) - 3
AN = 21 units.

Find the value of (f o g)' at the given value.
To find the value of (f o g)' at a given value, you first need to understand the concept of composite functions and the chain rule of differentiation. Let's break it down step by step.
To find the value of (f o g)' at a given value, you need to evaluate g(x) and f(x), find their derivatives, and use the chain rule to find the derivative of (f o g) at the given value. It is important to understand the concepts of composite functions and the chain rule to be able to solve problems involving these concepts.
What are composite functions? Composite functions are functions that are formed by composing two or more functions. The notation used to denote composite functions is (f o g)(x), which means that the output of function g is used as the input for function f. In other words, we first evaluate g(x), and then use the result as the input for f(x).
What is the chain rule of differentiation? The chain rule of differentiation is a method used to find the derivative of composite functions. It states that if a function is composed of two or more functions, then its derivative can be found by taking the derivative of the outer function and multiplying it by the derivative of the inner function.
To find the value of (f o g)' at a given value, we need to follow these steps:1. Find g(x) and f(x)2. Find g'(x) and f'(x)3. Evaluate g(x) at the given value4. Use the chain rule to find (f o g)' at the given value
step 1: Find g(x) and f(x)Let's say that we have two functions: g(x) = x^2 + 3x + 1 and f(x) = sqrt(x). To find (f o g)(x), we first need to evaluate g(x) and then use the result as the input for f(x). Therefore, (f o g)(x) = f(g(x)) = sqrt(x^2 + 3x + 1)
Step 2: Find g'(x) and f'(x)To find g'(x), we need to take the derivative of g(x) using the power rule and the sum rule. Therefore, g'(x) = 2x + 3To find f'(x), we need to take the derivative of f(x) using the power rule and the chain rule. Therefore, f'(x) = 1/2(x)^(-1/2)
Step 3: Evaluate g(x) at the given valueSuppose we want to find (f o g)' at x = 2. To do this, we need to first evaluate g(x) at x = 2. Therefore, g(2) = 2^2 + 3(2) + 1 = 11
Step 4: Use the chain rule to find (f o g)' at the given value now we can use the chain rule to find (f o g)' at x = 2. Therefore, (f o g)'(2) = f'(g(2)) * g'(2) = 1/2(11)^(-1/2) * (2)(3) = 3/sqrt(11)

Which point(s) lie on the graph of the equation y = -5x - 3?
Plug in values of x to find corresponding values of y.
For example, replace x with 0 to find that...
y = -5x-3
y = -5*0 - 3
y = 0 - 3
y = -3
We have x = 0 lead to y = -3.
Therefore, the point (0, -3) is on this line. This is the y intercept.
Now try something like x = 1
y = -5x-3
y = -5*1 - 3
y = -5 - 3
y = -8
It shows the point (1,-8) is also on the line.
The straight line goes through (0,-3) and (1,-8)
We can repeat this process infinitely many times since there are infinitely many numbers to pick for x.

After being rejected for employment, Kim Kelly learns that the Bellevue Credit Company has hired only five women among the last 18 new employees. She also learns that the pool of applicants is very large, with an approximately equal number of qualified men as qualified women. Help her address the charge of gender discrimination by finding the probability of getting five or fewer women when 18 people are hired, assuming that there is no discrimination based on gender.
Does the resulting probability really support such a charge?
Answer:
0.0481 = 4.81% probability of getting five or fewer women when 18 people are hired. Since this probability is lower than 5%, it means that five or fewer woman being hired is an unlikely event, and supports the charge.
Step-by-step explanation:
For each new employee hired, there are only two possible outcomes. Either it is a woman, or it is not. The probability of an employee being a woman is independent of any other employee. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
And p is the probability of X happening.
She also learns that the pool of applicants is very large, with an approximately equal number of qualified men as qualified women.
This means that \(p = 0.5\)
Help her address the charge of gender discrimination by finding the probability of getting five or fewer women when 18 people are hired, assuming that there is no discrimination based on gender.
This is \(P(X \leq 5)\) when \(n = 18\)
So
\(P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)\)
In which
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 0) = C_{18,0}.(0.5)^{0}.(0.5)^{18} \approx 0\)
\(P(X = 1) = C_{18,1}.(0.5)^{1}.(0.5)^{17} = 0.0001\)
\(P(X = 2) = C_{18,2}.(0.5)^{2}.(0.5)^{16} = 0.005\)
\(P(X = 3) = C_{18,3}.(0.5)^{3}.(0.5)^{15} = 0.0031\)
\(P(X = 4) = C_{18,4}.(0.5)^{4}.(0.5)^{14} = 0.0117\)
\(P(X = 5) = C_{18,5}.(0.5)^{5}.(0.5)^{13} = 0.0327\)
\(P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0 + 0.0001 + 0.0005 + 0.0031 + 0.0117 + 0.0327 = 0.0481\)
0.0481 = 4.81% probability of getting five or fewer women when 18 people are hired. Since this probability is lower than 5%, it means that five or fewer woman being hired is an unlikely event, and supports the charge.
