The formula provides insights into the relationship between price and demand for Papa's Fried Chicken, indicating how changes in price affect the number of buckets of chicken sold.
From the formula b = 100 - 5p, we can infer the following:
The formula represents a linear relationship between the number of buckets of chicken sold (b) and the price per bucket (p).
The coefficient of p, which is -5, indicates that for every increase of 1 unit in the price, the number of buckets sold decreases by 5 units. Conversely, for every decrease of 1 unit in the price, the number of buckets sold increases by 5 units.
The intercept term of 100 represents the maximum number of buckets that can be sold at a price of 0. This suggests that there is a limit to the number of buckets that customers are willing to purchase, regardless of the price.
The formula assumes a downward-sloping demand curve, indicating that as the price increases, the quantity demanded decreases. This aligns with the typical behavior of most goods or services.
The formula implies that there may be an optimal price point where the number of buckets sold is maximized. Finding this price point would involve finding the value of p that maximizes the expression 100 - 5p.

Find the coordinates of point P along the directed line segment AB that partitions it so that the ratio of AP to PB is 2:1.
Answer:
coordinates of P are (2, 1).
Step-by-step explanation:
Let P be the point that partitions the line segment AB such that AP: PB = 2:1.(m:n) Then we can use the line ratio formula:
[tex]\bold{x = \frac{xB * m + xA*n}{m + n}}[/tex]
[tex]\bold{y = \frac{yB * m + yA*n}{m + n}}[/tex]
where (xA, yA) and (xB, yB) are the coordinates of A and B respectively, and m is the ratio of AP to PB, which is 2:1.
Substituting the given values, we get:
[tex]\bold{x = \frac{4*2+ (-2)*1}{2 + 1}}=2[/tex]
[tex]\bold{y = \frac{0 * 2 + 3*1}{2 + 1}= 1}[/tex]
Therefore, the coordinates of P are (2, 1).
Answer:
(2, 1)
Step-by-step explanation:
If the line segment AB is partitioned so that the ratio of AP to PB is 2 : 1, then point P is two-thirds of the way along AB.
Point A is located at (-2, 3) and point B is located at point (4, 0).
Since the difference between the x and y values of points A and B are multiples of 3, we can visually partition AB into 3 sections of equal length by placing points at (0, 2) and (2, 1).
Therefore, as point P is two-thirds of the way along AB, point P is located at (2, 1).
To prove this mathematically, we can use the Section Formula for Internal Division:
[tex]\boxed{\begin{minipage}{8.1 cm}\underline{Section Formula - Internal Division}\\\\\\$P(x,y)=\left(\dfrac{nx_1+mx_2}{m+n},\dfrac{ny_1+my_2}{m+n}\right)$\\\\\\where:\\\phantom{ww} $\bullet$ $\overline{AB}$ is the directed line segment.\\\phantom{ww} $\bullet$ $A(x_1, y_1)$ and $B(x_2, y_2)$ are the endpoints.\\\phantom{ww} $\bullet$ Point $P$ divides the segment in the ratio $m : n$.\\ \end{minipage}}[/tex]
Given values:
(x₁, y₁) = A = (-2, 3)(x₂, y₂) = B = (4, 0)m : n = 2 : 1Substitute the values into the formula:
[tex]\begin{aligned}P(x,y)&=\left(\dfrac{nx_1+mx_2}{m+n},\dfrac{ny_1+my_2}{m+n}\right)\\\\&=\left(\dfrac{1 \cdot (-2)+2 \cdot 4}{2+1},\dfrac{1 \cdot 3+2 \cdot 0}{2+1}\right)\\\\&=\left(\dfrac{-2+8}{3},\dfrac{3+0}{3}\right)\\\\&=\left(\dfrac{6}{3},\dfrac{3}{3}\right)\\\\&=\left(2,1\right)\end{aligned}[/tex]
Hence proving the the location of point P on the coordinate plane is (2, 1).

Three brothers decide to paint a wall. The eldest brother could have painted it himself in 3 hours, the middle brother would have taken 4 hours and the youngest would have taken 6. How long will it take them to paint the wall working together?
It will take them 2.4 hours or 2 hours and 24 minutes to paint the wall working together.
We have,
We can use the formula:
1/Time taken to complete task = Work done / Time
Let's say the work to be done is to paint the whole wall. We can represent the work done by each brother as follows:
Eldest brother's work done in 1 hour = 1/3
Middle brother's work done in 1 hour = 1/4
The youngest brother's work done in 1 hour = 1/6
Now, we can add up their work done in 1 hour:
1/3 + 1/4 + 1/6 = 2/4
Simplifying, we get:
5/12
This means that together, the three brothers can complete 5/12 of the work in one hour.
To find out how long it would take them to complete the whole work
(paint the wall), we can use the same formula:
1/Time taken to complete task = Work done / Time
Let's say the time taken for the three brothers to complete the work is 't'. Then we can write:
1/t = 5/12
Solving for 't', we get:
t = 12/5 hours or 2.4 hours

The ratio of the exterior and interior angle of a regular polygon is 2:3. Find the number of sides in the polygon.
Answer:
5 sides
Step-by-step explanation:
the sum of the interior angle and exterior angle = 180°
sum the parts of the ratio, 2 + 3 = 5 parts , then
180° ÷ 5 = 36° ← value of 1 part of the ratio
exterior angle = 2 × 36° = 72°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular then the exterior angles are congruent , so
number of sides = 360° ÷ 72° = 5

These tables could be used to verify that the functions they represent are inverses of each other
To verify if two functions are inverses of each other, we need to check if the composition of the two functions gives the identity function.
In other words, if f and g are two functions, then we need to check if f(g(x)) = x and g(f(x)) = x for all x in their domains.
We can create two tables, one for f and one for g, and use them to compute the compositions.
If the compositions give the identity function, then the functions are inverses of each other.
Based on this, the two tables that could be used to verify that the functions are inverses of each other are:
(a) x -5 -3 0 2 4
y 4 0 -6 -10 -14

Question: Find a 95% confidence interval for the true proportion of adults who are dissatisfied with the quality of k-12 education. Show your work. Interpret your 95% confidence interval in context of the situation.
Answer:
Sure, here are the steps on how to find a 95% confidence interval for the true proportion of adults who are dissatisfied with the quality of k-12 education:
Find the sample proportion. The sample proportion is the number of people in the sample who are dissatisfied with the quality of k-12 education divided by the total number of people in the sample. In this case, the sample proportion is 54%.
Find the standard error of the sample proportion. The standard error of the sample proportion is a measure of how much the sample proportion can vary from the true proportion. In this case, the standard error of the sample proportion is 1.66%.
Find the 95% confidence interval. The 95% confidence interval is a range of values that is likely to contain the true proportion. To find the 95% confidence interval, we add and subtract 1.96 standard errors from the sample proportion. In this case, the 95% confidence interval is (52.34%, 55.66%).
Interpret the 95% confidence interval. The 95% confidence interval means that we are 95% confident that the true proportion of adults who are dissatisfied with the quality of k-12 education is within the range of values (52.34%, 55.66%).
In other words, if we were to repeat this survey many times, 95% of the time the confidence interval would contain the true proportion of adults who are dissatisfied with the quality of k-12 education.

In any coordinate system of the plane the points A; B; C have respectively for
coordinates A(1;3) , B(–2 ;1) , C(3 ;1).
1°) Place points A; B and C in the mark
2°) Calculate the coordinates of K middle of [AC]
3°) Calculate the components of the vector BC
4°) Consider point B' with coordinates (x;y). Calculate as a function of x and y the
components of AB' . Determine the coordinates of B' such that vector (BC)= vector (AB')
5°) Nature of quadrilateral ABCB’. Show that K is the midpoint of [BB'].
The coordinates of the midpoint K of AC are (2,2), the components of vector BC are (5,0), B' has coordinates (6,3), ABCB' is a parallelogram, and K is the midpoint of BB'.
1°) The points A(1,3), B(-2,1), and C(3,1) can be marked on the coordinate system as follows:
2°) To find the coordinates of the midpoint K of AC, we can use the midpoint formula:
K = ((x1 + x2)/2, (y1 + y2)/2) where (x1, y1) and (x2, y2) are the coordinates of A and C, respectively.
K = ((1 + 3)/2, (3 + 1)/2) = (2, 2)
3°) The components of the vector BC can be found by subtracting the components of B from the components of C:
BC = (3, 1) - (-2, 1) = (3 + 2, 1 - 1) = (5, 0)
4°) Let B' have coordinates (x,y). The components of AB' are given by subtracting the components of A from the components of B':
AB' = (x-1, y-3)
We want to find the coordinates of B' such that vector BC is equal to vector AB', or in other words, AB' = BC. This gives us the following system of equations:
x - 1 = 5
y - 3 = 0
Solving for x and y, we get:
x = 6
y = 3
Therefore, B' has coordinates (6, 3), and the components of AB' are (6-1, 3-3) = (5, 0), which is equal to the components of BC.
5°) Quadrilateral ABCB' is a parallelogram, since its opposite sides AB' and BC are equal and parallel. We have shown in part 4°) that AB' = BC, so the sides AB' and CB have the same length and are parallel. Therefore, ABCB' is a parallelogram.
To show that K is the midpoint of BB', we need to show that KB = KB' and that K is on the line segment BB'. Since B' has coordinates (6, 3), the components of vector BB' are (6-(-2), 3-1) = (8, 2).
Therefore, the midpoint of BB' has coordinates (-2+4, 1+1) = (2, 2), which is the same as the coordinates of K. Therefore, K is the midpoint of BB'.

a. The concentration would be 0.5 mg/L at approximately t = 40 hours.
b. The table representing the concentration of the drug in the bloodstream, t hours after administration is shown below.
c. A reasonable domain for this function is t ≥ 0.
d. The patient should receive the next intravenous dose of the drug in order to maintain a concentration above 1 mg/L and below 8 mg/L at t = 1.25 hour.
e. The concentration of the oral drug and the concentration of the intravenous drug would keep increasing over the first 20 hours after it is administered.
How to calculate when the concentration will be 0.5 mg/L?In order to determine the time when the concentration would be 0.5 mg/L, we would substitute the value of the concentration and then solve the quadratic function for time (t);
c(t) = 20t/(t² + 4)
0.5 = 20t/(t² + 4)
0.5(t² + 4) = 20t
0.5t² + 2 = 20t
0.5t² + 2 - 20t = 0
t² + 4 - 40t = 0
t² - 40t + 4 = 0
Time, t = 38.8998 ≈ 40 hours.
Part b
In this context, we would complete the table of values at various time (t) as follows;
t 0 2 4 6 8 10 12 14 16 18 20
c(t) 0 5 4 3 2.35 1.92 1.62 1.4 1.23 1.10 1.00
Part c
Since the concentration of the drug at time, t = 0 is equal to 0 mg/L and the concentration actually never becomes zero (0) for any value of time (t), we can reasonably infer and logically deduce that a reasonable domain for this quadratic function is t ≥ 0 or {0, ∞}.
Part d and e
Furthermore, the intravenous drug must be administered to the patient between the time interval 1.25 ≤ t ≤ 20 in order to maintain a concentration above 1 mg/L and below 8 mg/L.

Find the number of sides of a polygon whose sum of interior angles is given given as 6 right angles
Answer:
5 sides
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° ( n - 2) ← n is the number of sides
given sum is 6 right angles = 6 × 90° = 540° , then
180° (n - 2) = 540° ( divide both sides by 180° )
n - 2 = 3 ( add 2 to both sides )
n = 5

Event A: Choosing an even digit for the first numberEvent B: Choosing an odd digit for the second number.Given that the digits are non-zero digits and no two digits are the same, then we have
P(A) = 4/9
Also, we have
P(B) = 5/8
The probabilty is then calculated as
P(B|A) = P(B)
So, we have
P(B | A) = 5/8
Hence, the value of the probability P(B|A) is (d) 5/8

a. The concentration would be 0.5 mg/L at approximately t = 40 hours.
b. The table representing the concentration of the drug in the bloodstream, t hours after administration is shown below.
c. A reasonable domain for this function is t ≥ 0.
d. The patient should receive the next intravenous dose of the drug in order to maintain a concentration above 1 mg/L and below 8 mg/L at t = 1.25 hour.
e. The concentration of the oral drug and the concentration of the intravenous drug would keep increasing over the first 20 hours after it is administered.
How to calculate when the concentration will be 0.5 mg/L?In order to determine the time when the concentration would be 0.5 mg/L, we would substitute the value of the concentration and then solve the quadratic function for time (t);
c(t) = 20t/(t² + 4)
0.5 = 20t/(t² + 4)
0.5(t² + 4) = 20t
0.5t² + 2 = 20t
0.5t² + 2 - 20t = 0
t² + 4 - 40t = 0
t² - 40t + 4 = 0
Time, t = 38.8998 ≈ 40 hours.
Part b
In this context, we would complete the table of values at various time (t) as follows;
t 0 2 4 6 8 10 12 14 16 18 20
c(t) 0 5 4 3 2.35 1.92 1.62 1.4 1.23 1.10 1.00
Part c
Since the concentration of the drug at time, t = 0 is equal to 0 mg/L and the concentration actually never becomes zero (0) for any value of time (t), we can reasonably infer and logically deduce that a reasonable domain for this quadratic function is t ≥ 0 or {0, ∞}.
Part d and e
Furthermore, the intravenous drug must be administered to the patient between the time interval 1.25 ≤ t ≤ 20 in order to maintain a concentration above 1 mg/L and below 8 mg/L.
