A jar contains 8 large red marbles, 5 small red marbles, 7 large blue marbles, and 4 small blue marbles. if a marble is chosen at random, which of the conditional probabilities is larger, p(red|large) or p(large|red)?

Answers

8 large red, 5 small red, 7 large blue, 4 small blue:

totally = 24 marbles

P(red)= 13/24

let A red and B large

P(A/B)= P(A∩B)/P(B)

P(B)= 15/24 =.625

P(A∩B)= 8/24 = .333

P(A/B) =.333/.625 =.533

P(B/A) =.625/.333= 1.875

so the probability of p(large/red) is larger.

A test is worth 50 points. Multiple-choice questions are worth 1 point, and short-answer questions are worth 3 points. If the test has 20 questions, how many multiple-choice questions are there?
A. t for test, q for questions
B. m for multiple choice, s for short answer
C. s for short answer, t for test
D. p for points, m for multiple choice

apex mcr

Answers

Use the following formula to find the answer to this question:

S * Q + M * Q = P

Representations:

S = The amount of points for short-answer questions.

M = The amount of points for multiple-choice questions.

Q = Number of questions for each of the type of questions that add up to the total number of questions on the test (20 questions).

P = Total points on the test.

Since there is a total of 50 points on the 20 question test, you would need to divide up the amount of questions there are for each of the type there are on the test, short-answer, and multiple-choice.

3 * Q + 1 * Q = P

Now find how many of the type of questions there are out of 20 questions on the test that would add up to the total number of points on the test.

3 * Q + 1 * Q = 50

(15 + 5 = 20 questions on the test, 15 and 5 can be used for the number of questions for each type of question on the test).

3 * 15 + 1 * 5 = 50

45 + 5 = 50

50 = 50

So, your total number of multiple choice questions are: 5.
And, your total number of short answer questions are: 15.

If the graph of the function h is defined by = h(x)+x^2+9 is translated vertically downward by 9 units, it becomes the graph of a function g. Find the expression for
gx

Answers

The answer is g(x) = x².
Solution:
The graph of h(x) = x²+9 translated vertically downward by 9 units means that each point (x, h(x)) is shifted onto the point (x, h(x) - 9), that is,
(x, h(x)) → (x, h(x) - 9)
The translated graph that represents the function is defined by the expression for g(x):
g(x) = h(x) - 9 = x² + 9 - 9 = x²

h(x) = x²+9 → g(x) = x² shows that the graph of the equation g(x) = x² moves the graph of h(x) = x²+9 down nine units.

The greenhouse effect traps heat near earth's surface. Greenhouse gases in the atmosphere—carbon dioxide, water vapor, methane, and nitrous oxide—allow the shorter waves of ultraviolet radiation from the sun to enter earth's lower atmosphere. However, these gases do not allow the longer wavelengths of infrared radiation to pass back out to the outer atmosphere. The result is that the lower atmosphere heats up.This result happens naturally, but it can be accelerated by human activities. Since the late 1800s, human activity has greatly altered the amount of greenhouse gases that enter the atmosphere. Burning fossil fuels, farming, and clearing forests, as well as industry, have all contributed to increases of carbon dioxide (CO2), methane, nitrous oxide, and other greenhouse gases in the atmosphere.The result is that temperatures in the troposphere have gone up. Many scientists identify this increase in greenhouse gas emissions as contributing directly to global warming. This suggests that human activity has had an impact on the global climate.

Use part 1 of the fundamental theorem of calculus to find the derivative of the function. y = cos x (3 + v5)8 dv sin x

Answers

It looks like

[tex]y(x)=\displaystyle\int_{\cos x}^{\sin x}(3+v^5)^8\,\mathrm dv[/tex]

(If the limits are in the wrong order, just multiply the result by -1)

Split the integral at an arbitrary value between [tex]\cos x[/tex] and [tex]\sin x[/tex], and write [tex]y(x)[/tex] as

[tex]y(x)=\displaystyle\left\{\int_{\cos x}^c+\int_c^{\sin x}\right\}(3+v^5)^8\,\mathrm dv[/tex]

[tex]y(x)=\displaystyle\int_c^{\sin x}(3+v^5)^8\,\mathrm dv-\int_c^{\cos x}(3+v^5)^8\,\mathrm dv[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\cos x(3+\sin^5x)^8+\sin x(3+\cos^5x)^8[/tex]

Final answer:

The first part of the Fundamental Theorem of Calculus provides a method to find the derivative of a function. However, clarity is needed in the question as it has extra elements. If we consider the derivative of y = cos x (3 + √5)8 sin x, it would be f'(x) = -sin x (3 + √5)8 sin x + cos x (3 + √5)8 cos x.

Explanation:

Since the question asks for the derivative of the function y = cos x (3 + √5)8 dv sin x, we'll need to use the First Part of the Fundamental Theorem of Calculus. This theorem states that if a function f is continuous over the interval [a, b] and F is an antiderivative of f on [a, b], then the definite integral from a to b of f(x) dx equals F(b) - F(a). In this case, we have y = cos x (3 + √5)8 dv sin x which sadly is not clear due the presence of apparently extra and possibly typographical elements.

Assuming, the question intends to find derivative of y = cos x (3 + √5)8 sin x, we can proceed as follows:

Let f(x) = cos x (3 + √5)8 sin x. Then by applying the chain rule, we get: f'(x) = -sin x (3 + √5)8 sin x + cos x (3 + √5)8 cos x.

A plane left on time at noon on Monday. It arrived at its destination at 8:16PM the same day, which was 16 minutes late. On average, how many seconds did the plane fall behind every fifteen minutes?

Answers

The plane arrived on 8:16 pm and was 16 minutes late. This means the arrival time of plan was 8:00 pm. The plane left on noon i.e. 12:00 pm.

So total expected time of the journey was = 8 hours

8 hours means 8 x 60 minutes = 480 minutes

480 minutes can also be seen as 32 groups of 15 minutes each as 15 x 32 = 480.

In 32 groups of 15 minutes each the plane was late by a total of 16 minutes.

So, in every 15 minute the plane was late by 16/32 minute = 0.5 minute

Thus, we can conclude that on average the plane fall behind 0.5 minutes in every 15 minutes

To find the average delay per fifteen-minute interval, convert the total delay of 16 minutes into seconds, then divide by the number of fifteen-minute intervals between noon and 8:00 PM, yielding an average delay of 30 seconds per interval.

The question asks us to calculate how much time the plane fell behind schedule, on average, every fifteen minutes. Since the plane arrived 16 minutes late, we first need to convert this delay into seconds: 16 minutes is equal to 960 seconds (16 minutes imes 60 seconds/minute). To calculate the plane's average delay per fifteen-minute interval, we divide the total delay in seconds by the total number of fifteen-minute intervals between noon and the expected arrival time at 8:00 PM, which is 32 intervals (8 hours ×4 intervals/hour). Therefore, the average delay per interval is 960 seconds \/ 32 intervals = 30 seconds per interval.

Which describes a cost that fluctuates depending on the number of units produced A) Liability B) Revenue C) fixed cost D) Variable cost

Answers

Answer: D: Variable cost

Explanation: There are two aspects of cost in the process of production. One is fixed and the other is variable

The variable component is called as variable cost which fluctuates based on the number of units produced. The examples of variable costs include commissions, direct labor costs, manufacturing costs etc which depend on the number of units produced and sold

A cost that fluctuates depending on the number of units produced is called a variable cost.

Option D is the correct answer.

What is a variable cost?

A variable cost is a cost that changes proportionally to the level of activity or production volume.

We have,

The cost per unit varies depending on how many units are produced.

As more units are produced, the variable cost increases, and as fewer units are produced, the variable cost decreases.

This is in contrast to a fixed cost, which remains constant regardless of the level of production.

Examples of variable costs include direct labor, raw materials, and production supplies.

Thus,

QM Q2.) Find the multiplicities of the greatest zero, second greatest zero, and the smallest zero.

Answers

Method
First check out the zeros (first box).

Step One.
Put brackets around terms 1 and 2 and another set around terms 3 and 4.

f(x) = (x^3 + 8x^2) - (4x + 32) Watch out that you change the sign on the 32. Minus signs can be devastating. The idea is that when the brackets are removed, the question will be exactly as it was before you put the brackets there.

Step Two
Pull out any common factors.
f(x) = x^2(x + 8) - 4(x + 8)

Step Three.
If there is a common binomial pull it out as well. This is the hardest part of the problem. The binomials have to be exactly alike (in this case they are).

f(x) = (x + 8) (x^2 - 4)

Step Four
Factor (x^2 - 4). This is an exact difference of squares. It factors into
x^2 - 4 = (x + 2)(x - 2)

Step five
Find the zeros.
f(x) = (x + 8)(x - 2)(x + 2)

x + 8 = 0
x = - 8

x + 2 = 0
x = - 2

x - 2 = 0
x = 2

I know you didn't ask for all of this, but when someone asks a question, it's always a good idea to check the work done. In your case it was all correct. That's a very good thing.

If it takes 2 nurses 2 minutes to measure the blood pressure of 2 patients, how long would it take 200 nurses to measure the blood pressure of 200 patients (in minutes)?

Answers

Final answer:

One nurse takes 2 minutes to measure the blood pressure of one patient. With 200 nurses, each assigned to one patient, it will take all nurses 2 minutes to measure the blood pressure of 200 patients.

Explanation:

The question is asking for the time it would take a group of nurses to measure the blood pressure of an equal number of patients given a scenario. It works on the principle that if the number of nurses is directly proportional to the number of patients, the time it takes for one nurse to measure one patient's blood pressure will be the same, regardless of how many nurses or patients there are, as long as the ratio remains 1:1.

If it takes 2 nurses 2 minutes to measure the blood pressure of 2 patients, that means one nurse takes 2 minutes to measure the blood pressure of one patient. Therefore, if you have 200 nurses each measuring the blood pressure of one patient, it would still take 2 minutes for all 200 patients to have their blood pressure measured since each nurse is working with one patient individualy.
