The situation described is an example of "Biased Sampling" or "Selective Sampling" in advertising.
Biased or selective sampling refers to the act of intentionally selecting or presenting a subset of data or information that supports a specific claim or viewpoint while disregarding or ignoring other data or information that may present a different perspective. In this case, the advertisement selectively presents the endorsement of four out of five dentists to create the impression that SparklySafe gum is widely recommended.
The humorous portrayal of the fifth dentist falling asleep or being bitten by a squirrel serves as a creative way to dismiss or downplay the dissenting opinion. By focusing on the majority endorsement and providing a humorous explanation for the dissenting dentist, the advertisement aims to convince consumers that SparklySafe is the preferred choice among dentists.
However, it is important to approach such claims with critical thinking and consider the possibility of biased sampling. The advertisement may not accurately represent the opinions of all dentists and could be a strategic marketing tactic to promote the product.

Answer:
a) 7 +9(n -1)
b) (n +2)² +6
Step-by-step explanation:
You want expressions for the n-th terms of sequences that start ...
a) 7, 16, 25, 34, 43, ...
b) 15, 22, 31, ...
a)It is useful to look at the differences of terms of a sequence. Here the "first" differences are ...
16 -7 = 9
25 -16 = 9
34 -25 = 9
43 -34 = 9
The constant differences mean this is an arithmetic sequence. Its first term is a1 = 7, and the common difference is d = 9. The general term is ...
an = a1 +d(n -1)
an = 7 +9(n -1)
b)The first differences of the numbers of squares are ...
22 -15 = 7
31 -22 = 9
There aren't enough numbers to establish a definitive pattern, but we can assume that the second difference will continue to be 9 -7 = 2. The constant second differences mean the sequence can be described by a quadratic (degree 2) expression.
When the pattern is presented as a geometry, it is often useful to examine the geometry for clues. Here, we see the central body of squares forms a square that has n+2 squares on a side. Those not in that central square total 6, remaining constant from one figure to the next.
The expression for the number of squares can be ...
(n +2)² +6

Find all the zeros of p(x)=x^3+2x^2-3x+20
Answer:
x = -4
Step-by-step explanation:
Find the zeros of a function by setting the function equal to zero.
Basically, solve for x when p(x) = 0. Thus:
\(0=x^3+2x^2-3x+20\)
↓ seperate to factor out \((x+4)\)
\(0=(x^3 -3x) + (2x^2 + 20)\)
↓ factor out \((x+4)\)
\(0 = (x + 4)(x^2 - 4x) + (x+4)(2x + 5)\)
↓ simplify by combining the right part of each term
\(0=(x+4)(x^2 - 4x + 2x + 5)\)
\(0=(x+4)(x^2 -2x + 5)\)
↓ split into two equations using the zero factor principle
(if \(AB = 0\), then \(A = 0\) or \(B = 0\))
\(x + 4 = 0\) \(x^2 - 2x + 5 = 0\)
\(x = -4\) ↓ complete the square
\(x - 2x + 1 = -5 + 1\)
\((x-1)^2 = -4\)
\(x-1 = \sqrt{-4}\)

A farmer plans to enclose a rectangular pasture adjacent to a river. (see figure). The pasture must contain 320,000 square meters in order to provide enough grass for the herd. What dimensions will require the least amount of fencing if no fencing is needed along the river?
y = ? (m)
x = ? (m)
The dimensions of the square pasture would be approximately 565.7 meters by 565.7 meters.
Let's assume the length of the rectangular pasture along the river is x meters. Since no fencing is needed along the river, only three sides of the pasture will require fencing. Therefore, the perimeter of the pasture, which represents the amount of fencing required, will be equal to 2x + y meters.
The area of the rectangular pasture is given as 320,000 square meters, so we have the equation xy = 320,000.
To minimize the amount of fencing, we need to minimize the perimeter. The perimeter equation can be rewritten as P = 2x + (320,000/x).
To find the minimum value of P, we can take the derivative of P with respect to x and set it equal to zero. By solving the resulting equation, we find that x ≈ 565.7 meters.
Substituting this value of x into the area equation xy = 320,000, we can solve for y, which also turns out to be approximately 565.7 meters.
Therefore, the dimensions that require the least amount of fencing are approximately 565.7 meters by 565.7 meters, forming a square-shaped pasture.

What is the slope of the line that passed through the points (-3,-3) and (-5,-2)
Answer: -1/2
Step-by-step explanation:
Formula for finding slope: (y1 - y2) / (x1 - x2).
This is because the slope is the change of y and x values, so we shall find the difference between the y and x points.
Let x1 be -3, and y1 be -3, and the second point- let x2 be -5, and y2 as -2.
We plug them in and we get (-3 - (-2)) / (-3 - (-5)).

1. What are the 3 conditions for a function to be continuous at xa? 2. the below. Discuss the continuity of function defined by graph 3. Does the functionf(x) = { ***
The three conditions for a function to be continuous at a point x=a are:
a) The function is defined at x=a.
b) The limit of the function as x approaches a exists.
c) The limit of the function as x approaches a is equal to the value of the function at x=a.
The continuity of a function can be analyzed by observing its graph. However, as the graph is not provided, a specific discussion about its continuity cannot be made without further information. It is necessary to examine the behavior of the function around the point in question and determine if the three conditions for continuity are satisfied.
The function f(x) = { *** is not defined in the question. In order to discuss its continuity, the function needs to be provided or described. Without the specific form of the function, it is impossible to analyze its continuity. Different functions can exhibit different behaviors with respect to continuity, so additional information is required to determine whether or not the function is continuous at a particular point or interval.

Based on the provided question, it seems like you are asking about the most efficient evaluation method, either by hand or using a computer. To determine which method is the most suitable, you need to consider the complexity of the evaluation process and the number of alternatives.
Using a computer is generally faster and more accurate when dealing with large datasets or complex calculations. On the other hand, evaluating by hand may be more suitable for smaller datasets or simpler calculations. It can provide a more hands-on approach, allowing for a deeper understanding of the evaluation process. However, this method is generally more time-consuming and prone to human error.
To select the most appropriate evaluation method, consider the complexity of the task and the available resources. If the evaluation involves a large amount of data or complex calculations, using a computer would likely be the most efficient choice. However, if the task is relatively simple or involves a smaller dataset, evaluating by hand may suffice. In conclusion, the choice between evaluating by hand or using a computer depends on the complexity of the task and the available resources. Consider these factors to determine the most suitable method.

In a middle-school mentoring program, a number of the sixth graders are paired with a ninth-grade student as a buddy. no ninth grader is assigned more than one sixth-grade buddy. if 1/3 of all the ninth graders are paired with 2/5 of all the sixth graders, what fraction of the total number of sixth and ninth graders have a buddy
The total fraction of sixth and ninth graders who have a buddy is (n + s)/5.
Let there be s sixth graders and n ninth graders. Since 2/5 of the sixth graders are paired with 1/3 of the ninth graders, we can set up the equation: (2/5)s = (1/3)n
Multiplying both sides of the equation by 15 gives us: 6s = 5n
Then, we can rewrite the equation as: s + n = 5n/6
We can simplify this equation to: s + n = (5/6)n + (5/6)s
Combining like terms on the right side of the equation gives us: s + n = (11/6)s + (5/6)n
Subtracting (5/6)n from both sides of the equation gives us: s + n - (5/6)n = (11/6)s
Combining like terms on the left side of the equation gives us: (6/6)s + (1/6)n = (11/6)s
Subtracting (11/6)s from both sides of the equation gives us: (1/6)n = -(5/6)s
Dividing both sides of the equation by (1/6) gives us: n = -(5/1)s
Multiplying both sides of the equation by (-1) gives us: n = (5/1)s
Dividing both sides of the equation by 5 gives us: n/5 = s/5
The fraction of sixth and ninth graders who have a buddy is equal to the number of ninth graders who have a buddy (n/5) plus the number of sixth graders who have a buddy (s/5). The total fraction of sixth and ninth graders who have a buddy is therefore: (n/5) + (s/5) = (n + s)/5.

Step-by-step explanation:
Answer:
John is currently 6 years old.
You can find this by setting John's original age as x and Jose's original age as x + 6. Then we can set up an equation adding two to both.
John's new age = x + 2
Jose's new age = x + 8
Now we can multiply John's new age by two and set equal to Jose's age, since Jose's new age is twice as much as John's.
2(x + 2) = x + 8
2x + 4 = x + 8
x + 4 = 8
x = 4
This means John's original age is 4 and his new age is 6.

Write an absolute value inequality to represent each situation.
A friend is planning a trip to Alaska. He purchased a coat that is recommended for outdoor temperatures from -15⁰ F to 45⁰F . Let t represent the temperature for which the coat is intended.
Answer: |t - 15| ≤ 30 ; -30 ≤ t - 15 ≤ 30
Step-by-step explanation:
To set up the equation, we have to find the center, and the tolerance, so that we can use formula "|x - c| ≤ t"
First, we can find the tolerance by adding both number, then dividing by 2 --> -15 + 45 = 30 --> 30/2 = 15, so we now know that the center is 15
Next, we can find the tolerance by finding the distance between the center and one of the number --> 15 - (-15) = 30, so we now know that the tolerance is 30
Now we can set up our equation,
center (c) = 15
tolerance (t) = 30
|t - 15| ≤ 30
Now that we have our equation, we can set up the inequality
|x - c| ≤ t = -t ≤ x - c ≤ t
so,
-30 ≤ t - 15 ≤ 30
