Population equilibria can be stable or unstable. If, when a population deviates a bit from the equilibrium value (as populations inevitably do), it tends to return to it, this is a stable equilibrium; if, however, when the population deviates from the equilibrium it tends to diverge from it ever further, this is an unstable equilibrium. Think of a ball in the pocket of a snooker table versus a ball balanced on a snooker cue. Unstable equilibria are a feature of Allee effect models such as (4). Use a phase portrait of the autonomous equation (4) to determine whether the nonzero equilibria that you found in Problem 2 are stable or unstable.
equation (4)
the logistic equation, is:
(dN/dt)= rN(1- (N/K))((N/A)-1). where A is called the Allee threshold. The value N(t)=A is the population size below which the population growth rate becomes negative due to an Allee effect— situated at a value of N somewhere between N=0 and N=K, that is, 0
Answers
The stability of the nonzero equilibria found in Problem 2 can be determined by analyzing the phase portrait of the autonomous equation (4).
If the phase portrait shows that any slight deviation from the equilibrium point results in the population returning to the equilibrium point, then the equilibrium is stable.
On the other hand, if any slight deviation from the equilibrium point causes the population to diverge further from the equilibrium point, then the equilibrium is unstable.
To analyze the phase portrait, we need to first find the Jacobian matrix of the autonomous equation (4) evaluated at the nonzero equilibria. Then, we can determine the eigenvalues of the Jacobian matrix and use them to classify the stability of the equilibria.

If a chord of a circle is 6 and is twice as far from the center chord of length 12, how long is the radius of the circle?
Answers
Answer and explanation:
A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm

Kenneth bought a car for $16,200, but he received $900 cash back. He will make monthly payments at a 4.56% APR, compounded monthly, for 36 months. Kenneth is wondering how much money he saved by receiving the cash back. Help him figure out the answer.
Part I: How much will Kenneth have left to pay after receiving the cash back?
Part II: What is the periodic rate at which Kenneth will be charged interest?
Part III: What will Kenneth's monthly payment be?
Part IV: What would Kenneth's monthly payment have been if he hadn't received the cash back?
Part V: How much money did Kenneth save by receiving the cash back?
Answers
Part I:
The amount Kenneth has left to pay after receiving the cash back is:
$16,200 - $900 = $15,300
Part II:
The periodic rate at which Kenneth will be charged interest can be found using the formula:
r = (APR/12)/100
where APR is the annual percentage rate.
r = (4.56/12)/100
r = 0.0038
So the periodic rate is 0.0038 or 0.38%.
Part III:
To find Kenneth's monthly payment, we can use the formula for the present value of an annuity:
PMT = R * (PV * r) / (1 - (1 + r)^-n)
where PMT is the monthly payment, PV is the present value, r is the periodic interest rate, and n is the number of periods.
PV = $15,300
r = 0.0038
n = 36
R is the factor by which the payments change each period, but in this case, the payments are equal, so R is equal to 1.
PMT = 1 * ($15,300 * 0.0038) / (1 - (1 + 0.0038)^-36)
PMT = $451.66 (rounded to the nearest cent)
So Kenneth's monthly payment is $451.66.
Part IV:
If Kenneth hadn't received the cash back, his present value would have been $16,200, so we can use the same formula as before to find his monthly payment:
PV = $16,200
r = 0.0038
n = 36
PMT = 1 * ($16,200 * 0.0038) / (1 - (1 + 0.0038)^-36)
PMT = $478.59 (rounded to the nearest cent)
So Kenneth's monthly payment would have been $478.59.
Part V:
To find out how much money Kenneth saved by receiving the cash back, we can subtract his monthly payment with the cash back from his monthly payment without the cash back:
$478.59 - $451.66 = $26.93 (rounded to the nearest cent)
So Kenneth saved $26.93 per month, or a total of:
$26.93 * 36 = $968.28
Therefore, Kenneth saved $968.28 by receiving the cash back.

Explanation:
The expected population proportion that prefers to shop at places with loyalty cards is between 54.6% to 61.4% if, in a survey conducted by a retail store, 58% of the sampled respondents said they prefer to shop at places with loyalty cards. If the margin of error is 3.4%
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
The formula for finding the MOE:
\(\rm Z{score}= \frac{s}{\sqrt{n} }\)
Where is the z score at the confidence interval
s is the standard deviation
n is the number of samples.
The percent of sample respondents = 58%
Margin of error = 3.4%
The expected population that prefers to shop at places with loyalty cards is:
= (58±3.4%)
Take minus sign:
= 54.6%
Take plus sign:
= 61.4%
Thus, the expected population proportion that prefers to shop at places with loyalty cards is between 54.6% to 61.4% if, in a survey conducted by a retail store, 58% of the sampled respondents said they prefer to shop at places with loyalty cards. If the margin of error is 3.4%

Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 159 disks are summarized as follows:
Shock Resistance
scratch resistance high low
high 70 9
low 16 5
Let A denote the event that a disk has high shock resistance, and let B denote the event that a disk has high scratch resistance. If a disk is selected at random, determine the following probabilities.
a. P(A)=86/100
b. P(B)=79/100
c. P(A')=7/50
d. P(A U B)=95/100
e. P(A' U B)= ???
Answers
The probability of the event A' (not A) or the complement of event A, which represents a disk not having high shock resistance, is 7/50.
To calculate this probability, we need to find the number of disks that do not have high shock resistance. From the given data, we can see that there are a total of 159 disks. Out of these, 70 disks have high shock resistance (event A), so the number of disks without high shock resistance is 159 - 70 = 89.
Therefore, the probability of A' is 89/159, which simplifies to 7/50.
In terms of interpretation, this probability represents the likelihood of randomly selecting a disk that does not have high shock resistance from the given sample of 159 disks. It indicates the proportion of disks that do not meet the criteria for high shock resistance.
It's worth noting that the calculation of P(A' U B) (the probability of either A' or B occurring) was not provided. If you provide the necessary information, I can assist you in calculating that probability as well.

Find two quadratic functions, one that opens upward and one that opens downward, whose graphs have the given x-intercepts. (-5,0), (5,0) opens upward f(x)=x²+x-5 X opens downward f(x)=x²-x+5
Answers
We have found two quadratic functions with x-intercepts (-5,0) and (5,0): f(x) =\(x^2 - 25\), which opens upward, and g(x) = \(-x^2 + 25\), which opens downward.
For the quadratic function that opens upward, we can use the x-intercepts (-5,0) and (5,0) to set up the equation:
f(x) = a(x + 5)(x - 5)
where a is a constant that determines the shape of the parabola. If this function opens upward, then a must be positive. Expanding the equation, we get:
f(x) = a(x^2 - 25)
To determine the value of a, we can use the fact that the coefficient of the x^2 term in a quadratic equation determines the shape of the parabola. Since we want the parabola to open upward, we need the coefficient of x^2 to be positive, so we can set a = 1:
f(x) = x^2 - 25
For the quadratic function that opens downward, we can use the x-intercepts (-5,0) and (5,0) to set up the equation:
g(x) = a(x + 5)(x - 5)
where a is a constant that determines the shape of the parabola. If this function opens downward, then a must be negative. Expanding the equation, we get:
g(x) = a(x^2 - 25)
To determine the value of a, we can use the fact that the coefficient of the x^2 term in a quadratic equation determines the shape of the parabola. Since we want the parabola to open downward, we need the coefficient of x^2 to be negative, so we can set a = -1:
g(x) = -x^2 + 25

Kelly has 97 apples, Jason has 72. How may proportional relationships are there?
Answers
There are 6984 inverse proportional relationships and the direct proportional relationships are 97/72.
Given that:
Kelly has 97 apples, and Jason has 72.
The relationship between two variables, X and Y, is directly proportional if it can be expressed in terms of Y/X = k or Y = Xk.
Y/X = k
Substitute the given X and Y values and solve for k.
Suppose, Y = 97, X = 72
then k = 97/72
Distinguish a proportional relationship from other relations, including an inverse relationship (XY = k or Y = k/X).
An inverse proportional relationship is one in which two quantities vary inversely with respect to each other. We say that the variable Y changes inversely with X if
Y = k/X
Substitute the given X and Y values and solve for k.
Suppose, Y = 97, X = 72
then k = 97 x 72
=> k = 6984
Hence, there are 6984 inverse proportional relationships and direct proportional relationships are 97/72 between Kelly which has 97 apples, and Jason which has 72.

which of the following is not an advantage of using a sample versus a census? question 3 options: smaller dataset to analyze cost ready access to respondents population size
Answers
Out of the given options, the one that is not an advantage of using a sample versus a census is population size. The reason for this is that whether you use a sample or a census, the population size remains the same. However, there are several advantages to using a sample over a census.
Firstly, a sample generates a smaller dataset to analyze, which can save time and resources. Secondly, using a sample can be less expensive than conducting a census, which involves surveying every member of the population. Lastly, using a sample provides ready access to respondents, as it is often easier to reach a smaller group of people than an entire population. However, it is important to note that using a sample also has its limitations, such as the potential for sampling bias and the need to ensure that the sample is representative of the population being studied. Overall, the choice between using a sample or a census depends on the research question, available resources, and the level of accuracy and precision required.
