According to a recent article in the Wall Street Journal, 40% of web surfers who view online pop up ads remember them. Suppose a random sample of 5 web surfers is selected. What is the standard deviation in the number that will remember the ad
Answers
Answer:
The value is \(\sigma = 1.0954\)
Step-by-step explanation:
From the question we are told that
The proportion of people that remember the ad is p = 0.40
The sample size is n = 5
Generally this study of number of web surfers who view online pop up ads and remember them follow binomial distribution in that the outcome is two (which either they remember them or not) , the number of trial is finite , each the two outcome is consistent throughout the study.
Generally the standard deviation in the number that will remember the ad is mathematically represented as
\(\sigma = \sqrt{n * p * (1- p)}\)
=> \(\sigma = \sqrt{ 5 * 0.40 * (1- 0.40)}\)
=> \(\sigma = 1.0954\)

Sunset Lake is stocked with 2800 rainbow trout and after 1 year the population has grown to 7000. Assuming logistic growth with a carrying capacity of 28000, find the growth constant kk, and determine when the population will increase to 14600.
Answers
The growth constant is 1.0986 and the trout population will increase to 14600 after 2.1 years. The result is obtained by using the logistic equation.
How to find the increase of population?The increase of population can be found by using the logistic equation. It is
\(P(t) = \frac{K}{1 + Ae^{-kt} }\)
Where
P(t) = population at time t (in years)K = carrying capacityA = (K- P₀)/P₀k = growth constant of proportionalityt = time (in years)Sunset Lake is stocked with the rainbow trout. We have
P₀ = 2800P(1) = 7000K = 28000Find the growth constant k and time t when P(t) = 14600!
A = (K - P₀)/P₀
A = (28000 - 2800)/2800
A = 25200/2800
A = 9
After 1 year, we have 7000 rainbow trout. The growth constant is
\(7000 = \frac{28000}{1 + 9e^{-k(1)} }\)
\(1 + 9e^{-k} = 4\)
\(9e^{-k} = 3\)
\(e^{-k} = \frac{1}{3}\)
k = - ln (1/3)
k = 1.0986
Use k value to find the time when the population will increase to 14600!
\(14600 = \frac{28000}{1 + 9e^{-1.0986t} }\)
\(1.9178 = 1 + 9e^{-1.0986t}\)
\(0.9178 = 9e^{-1.0986t}\)
\(\frac{0.9178 }{9} = e^{-1.0986t}\)
\(t = \frac{ln \: 0.10198}{-1.0986}\)
t = 2.078
t ≈ 2.1 years
It is in another 1.1 years after t = 1.
Hence, the growth constant k is 1.0986 the population will increase to 14600 when t is 2.1 years.

2. You and your coworkers each bought scooters to get to work that costs $550. If 1
out of 20 people break their scooters or have them stolen, and you work with 40
people, how much will each member need to pay if you all form an insurance company
for your scooters?
Answers
The amount each member needs to pay is $27.50
To solve this problemIf 1 in 20 people has their scooters stolen or broken, that means 2 people will need to file a claim for their scooters (1/20 * 40).
We multiply the number of claims by the price of each scooter to determine the total amount of insurance required: 2 * $550 = $1100.
The cost of the insurance will be covered by equal contributions from each of the 40 participants.
Therefore, the amount each member needs to pay is $1100 / 40 = $27.50.

The solution to given linear inequality, 6(x1.5) + 30 < 48, is x < 2
Solving linear inequalitiesFrom the question, we are to solve the given linear inequality
The given linear inequality is
6(x1.5) + 30 < 48
First, we will write this inequality properly.
The inequality can be properly written as
6(1.5x) + 30 < 48

6(1.5x) + 30 < 48
Subtract 30 from both sides of the equation
6(1.5x) + 30 - 30 < 48 - 30
6(1.5x) < 18
Divide both sides of the inequality by 6
6(1.5x)/6 < 18/6

You pick a card at random, put it back, and then pick another card at random. 5 6 7 8 What is the probability of picking a prime number and then picking a prime number? Simplify your answer and write it as a fraction or whole number.
Answers
In fraction form, the answer is 1/4, which represents the simplified probability of the given event occurring.
To find the probability of picking a prime number and then picking another prime number, we first need to determine the total number of possible outcomes and the number of favorable outcomes.
Given the four numbers: 5, 6, 7, and 8, we can see that there are two prime numbers (5 and 7) and two non-prime numbers (6 and 8).
The total number of possible outcomes is 4 since there are four cards to choose from.
Now, let's consider the favorable outcomes, which are picking a prime number and then picking another prime number.
The probability of picking a prime number on the first draw is 2/4, as there are two prime numbers out of the four total cards.
Since we replace the card before the second draw, the probability of picking a prime number on the second draw is also 2/4.
To find the probability of both events occurring, we multiply the individual probabilities:
(2/4) * (2/4) = 4/16 = 1/4
Therefore, the probability of picking a prime number and then picking another prime number is 1/4.

The line segment joining the points P(-3,2) and Q(5,7) is divided by the y-axis in the ratio:
Answers
Answer:
Step-by-step explanation:
The line segment joining two points P and Q can be represented by the equation of a straight line in the form y = mx + b, where m is the slope and b is the y-intercept.
To find the equation of the line, we need to find the slope, which can be calculated using the formula:
m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the points P and Q, respectively.
In this case, the coordinates are:
P = (-3, 2) and Q = (5, 7)
So, the slope is:
m = (7 - 2) / (5 - (-3)) = 5 / 8
Next, we can use either of the points to find the y-intercept. Let's use point P:
b = y - mx, where y and x are the y and x coordinate of the point, respectively.
In this case,
b = 2 - m * (-3) = 2 - (5/8) * (-3) = 2 + 15/8 = 89/8
So, the equation of the line joining the points P and Q is:
y = (5/8)x + 89/8
Now, to find the point where the line crosses the y-axis, we need to find the x-coordinate of the point where y = 0.
So, we have:
0 = (5/8)x + 89/8
Solving for x, we get:
x = -(89/8) / (5/8) = -89 / 5
This means that the line crosses the y-axis at the point (-89/5, 0). To find the ratio in which the line segment is divided by the y-axis, we need to find the ratio of the distance from the y-axis to point P to the distance from the y-axis to point Q.
Let's call the point of intersection with the y-axis R. The distances are then:
PR = (3, 2) and QR = (5 - (-89/5), 7)
The ratio of the distances is then:
PR / QR = (3, 2) / (5 - (-89/5), 7) = 3 / (5 + 89/5) = 3 / (94/5) = 15/47
So, the line segment joining the points P and Q is divided by the y-axis in the ratio 15:47.

Let \(f(x) = x^3 - 2x - 2\). Then differentiating, we get
\(f'(x) = 3x^2 - 2\)
We approximate \(f(x)\) at \(x_1=2\) with the tangent line,
\(f(x) \approx f(x_1) + f'(x_1) (x - x_1) = 10x - 18\)
The \(x\)-intercept for this approximation will be our next approximation for the root,
\(10x - 18 = 0 \implies x_2 = \dfrac95\)
Repeat this process. Approximate \(f(x)\) at \(x_2 = \frac95\).
\(f(x) \approx f(x_2) + f'(x_2) (x-x_2) = \dfrac{193}{25}x - \dfrac{1708}{125}\)
Then
\(\dfrac{193}{25}x - \dfrac{1708}{125} = 0 \implies x_3 = \dfrac{1708}{965}\)
Once more. Approximate \(f(x)\) at \(x_3\).
\(f(x) \approx f(x_3) + f'(x_3) (x - x_3) = \dfrac{6,889,342}{931,225}x - \dfrac{11,762,638,074}{898,632,125}\)
Then
\(\dfrac{6,889,342}{931,225}x - \dfrac{11,762,638,074}{898,632,125} = 0 \\\\ \implies x_4 = \dfrac{5,881,319,037}{3,324,107,515} \approx 1.769292663 \approx \boxed{1.769293}\)

A paper describes a study of the use of MRI (Magnetic Resonance Imaging) exams in the diagnosis of breast cancer. The purpose of the study was to determine if MRI exams do a better job than mammograms of determining if women who have recently been diagnosed with cancer In one breast have cancer in the other breast. The study participants were 980 women who had been diagnosed with cancer in one breast and for whom a mammogram did not detect cancer in the other breast.
These women had an MRI exam of the other breast, and 131 of those exams indicated possible cancer. After undergoing biopsies, it was determined that 40 of the 131 did in fact have cancer in the other breast, whereas 91 did not. The women were all followed for one year, and two of the women for whom the MRI exam did not indicate cancer in the other breast were subsequently diagnosed with cancer that the MRI did not detect.
Suppose that for women recently diagnosed with cancer In only one breast, the MRI is used to decide between the two "hypotheses.
H0: woman has cancer in the other breast
Ha: woman does not have cancer In the other breast
(Although these are not hypotheses about a population characteristic, this exercise illustrates the definitions of Type I and Type II errors.)
A) One possible error would be deciding that a woman who does have cancer in the other breast Is cancer-free. Is this a Type 1 or a Type II error?
B) There Is a second type of error that is possible In this setting. Describe this error.
A Type II error would be coming to the conclusion that the woman_______cancer in the other breast when in fact she_______cancer in the other breast.
Answers
Answer:
Step-by-step explanation:
A type I error occurs when the null hypothesis is rejected in favor of the alternative hypothesis when the null hypothesis is actually true.
A type II error occurs when the researcher fails to reject the null hypothesis when the null is false.
H0: woman has cancer in the other breast
Ha: woman does not have cancer In the other breast
A) One possible error would be deciding that a woman who does have cancer in the other breast Is cancer-free. Is this a Type 1 or a Type II error?
This error is a type I error as the patient does have cancer which should warrant failing to reject the null but the null was rejected in favour of the alternative.
A Type II error would be coming to the conclusion that the woman does have cancer in the other breast when in fact she does not have cancer in the other breast.
This is a second type of error that can occur and it is a type II error: failing to reject the null when not true.

where n is the number of the binomial trial on which the first success occurs and p is the probability of success on each trial
P(n) = p(1 - p)ⁿ⁻¹
P(3) = 0.8(1-0.8)³⁻¹
P(3) = 0.8(0.2)²
P(3) = 0.032

Answer:
6.6 °C
Step-by-step explanation:
Alabama temperature in Celsius:
F= 1.8C + 32
Put F = 112 in the above equation
112 = 1.8C + 32
112 - 32 = 1.8C
80 = 1.8C
