Step-by-step explanation:
what is the probability that a randomly selected guest is accepted by the host? what type of probability is this (marginal, joint, or conditional)?
Answers
To determine the probability that a randomly selected guest is accepted by the host, we need more information about the scenario. For instance, we should know the total number of guests and the number of accepted guests. Let's say there are 'n' guests, and 'a' guests are accepted by the host.
Step 1: Identify the terms.
- n: Total number of guests
- a: Number of accepted guests
Step 2: Calculate the probability.
To find the probability, we'll divide the number of accepted guests (a) by the total number of guests (n). So, the probability is:
P(Accepted) = a / n
Step 3: Identify the type of probability.
In this case, the probability we've calculated is the "marginal probability," as it represents the likelihood of a single event occurring (a guest being accepted) without considering any other factors or events.

a. The rate of change is 2.25. b. It would cost $38.25 to ride 20 miles in the taxi. c. You can ride about 9.86 miles in the taxi with $20.
What is function notation?Using symbols and variables, a mathematical function may be represented using function notation. It includes expressing the function as f(x), where x is the independent variable or input value and f is the function's name. The symbol f(x), which may also be interpreted as "f of x," stands for "the value of the function f at the value x". We may find the value of the function f, which is the dependent variable or output value, by supplying the value of x. When a function has a complex formula or contains many variables, function notation provides a clear and practical approach to represent mathematical connections.
Given that the equation of the line is y = 1.80x +2.25.
In the given equation, 2.25 indicates the first drop on the meter or the set fare for a taxi, which is charged regardless of how far you go.
b. For x = 20 mile we have:
y = 1.80(20) + 2.25 = 36 + 2.25 = 38.25
c. Solving for x for $20 we have:
20 = 1.80x + 2.25
1.80x = 20 - 2.25
1.80x = 17.75
x = 9.8611.
Hence, it would cost $38.25 to ride 20 miles in the taxi. c. You can ride about 9.86 miles in the taxi with $20.

Find the indefinite integral: S(-7secxtanx - 5sec²x)dx
Answers
The value of the indefinite integral: S(-7secxtanx - 5sec²x)dx is -7ln|sec(x) + tan(x)| - 5x + 5ln|sec(x)| + C
To integrate the expression S(-7sec(x)tan(x) - 5sec²(x))dx, we first use the identity sec²(x) = 1 + tan²(x) to rewrite the second term as -5 - 5tan²(x). Then we can split the integral into two parts as follows: S(-7sec(x)tan(x) - 5sec²(x))dx = -7Ssec(x)tan(x)dx - 5S(1 + tan²(x))dx = -7sec(x)dx - 5x - 5tan(x)dx
Now we can integrate each part separately. The integral of sec(x) is ln|sec(x) + tan(x)| + C, and the integral of tan(x) is ln|sec(x)| + C. Therefore, S(-7sec(x)tan(x) - 5sec²(x))dx = -7ln|sec(x) + tan(x)| - 5x + 5ln|sec(x)| + C where C is the constant of integration.

e \large 84,000m+36,000w=1,962,800
Step-by-step explanation:
Given the following :
Budgeted amount = $1,962,800
Cost of resurfacing a mile of 2- lane road = $84,000
Salary of additional worker = $36,000
Number of miles = m
Number of workers = w
equations that represents the relationship between the miles of 2-lane roads the department could resurface, m, and the number of new workers it could hire, w, if it the entire budget is spent ;
(Cost of a mile of 2-lane road * number of miles) = total budget
(84000m + 36000w) = 1,962,800
To make w, the subject of the formula :
36000w = 1962800 - 84000m
w = (1962800 - 84000m) / 36000
To make m, the subject of the formula :
84000m = 1962800 - 36000w
m = (1962800 - 36000w) / 84000

By how much did the population decrease?Also known as population decline, means the reduction in a human population size
Population in 2015 = Population in 2010 + Growth from 2010 to 2015
Population in 2015 = 167,000 + (8% of 167,000)
Population in 2015 = 167,000 + 13,360
Population in 2015 = 180,360
Population in 2020 = Population in 2015 - Decrease from 2015 to 2020
Population in 2020 = 180,360 - (3% of 180,360)
Population in 2020 = 180,360 - 5,411.8
Population in 2020 = 174,948.2
The population decrease from 2015 to 2020 is:

An artist has 12 paintings to sell at the ArtiGras Fine Arts Festival in Jupiter, Florida. The artist picks 7 paintings to display on the first day. You randomly select 7 paintings. What is the probability you select the paintings in the same order the artist displays them on the first day? Write your answer as a fraction in simplest form.
Answers
Explanation:
There are 12 paintings in total, and the artist selects 7 paintings to display on the first day. The order in which you select the 7 paintings matters in this case since you are trying to match the exact order in which the artist displays them.
To calculate the probability of selecting the paintings in the same order, we need to find the total number of ways to choose and arrange 7 paintings out of 12. This is a permutation problem, so we use the formula for permutations:
P(n, r) = n! / (n - r)!
where P(n, r) is the number of permutations of n objects taken r at a time, n! is the factorial of n, and r is the number of objects selected.
In this case, n = 12 (total number of paintings) and r = 7 (number of paintings to be selected and arranged).
P(12, 7) = 12! / (12 - 7)!
P(12, 7) = 12! / 5!
Next, we'll calculate the factorials:
12! = 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
5! = 5 × 4 × 3 × 2 × 1
Now, we can simplify the expression:
P(12, 7) = (12 × 11 × 10 × 9 × 8 × 7 × 6) / (5 × 4 × 3 × 2 × 1)
We can cancel out some factors:
P(12, 7) = (12 × 11 × 10 × 9 × 8 × 7 × 6) / (5 × 4 × 3 × 2 × 1) = 12 × 11 × 10 × 9 × 8 × 7 × 6 = 665,280
There are 665,280 different ways to select and arrange the 7 paintings.
Since there is only one correct order, the probability of selecting the paintings in the same order as the artist displays them on the first day is:
P = 1 / 665,280
So, the probability is 1/665,280
The answer as a fraction in simplest form is 1 39916800.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
n = 12 and r = 7,
so the number of possible outcomes is:
12 P 7 = 12! ( 12 − 7)! = 12! 5! = 39916800
The number of favorable outcomes is only one, since there is only one way to select the paintings in the same order as the artist displays them. Therefore, the probability of selecting the paintings in the same order as the artist displays them on the first day is:
P ( event) = number of favorable outcomes number of possible outcomes = 1 39916800
This fraction cannot be simplified further, so this is the final answer. The probability is very small, which makes sense because it is very unlikely to randomly select 7 paintings in the same order as the artist displays them.
Therefore, by probability the solution will be 1 39916800.

if the expression above is written in the form a bi, where a and b are real numbers, what is the value of b?
Answers
The required, expression -7 + 24i with the form a + bi, we can see that the value of b is 24.
To find the value of b in the expression (3 + 4i)^2, we can simply expand the expression and identify the coefficient of the imaginary part.
(3 + 4i)² = (3 + 4i)(3 + 4i)
Using the FOIL method, we can multiply the terms:
= 3 * 3 + 3 * 4i + 4i * 3 + 4i * 4i
= 9 + 12i + 12i + 16i²
Since i² is defined as -1, we can substitute it:
= 9 + 12i + 12i - 16
= -7 + 24i
Comparing the expression -7 + 24i with the form a + bi, we can see that the value of b is 24.

Answers
The random variable can only take on values greater than or equal to 2.83
A random variable is a variable that can take on different values depending on the outcome of a random process.
In this problem, we are given a probability density function (pdf) for a random variable and asked to find the value of the constant "a". The pdf, f(x), represents the probability of the random variable taking on a particular value, x.
Here we have the constant "a" in the equation
=> f(x)=12/X³, x>=a,
is the minimum value that the random variable can take on.
This means that the total probability of the random variable taking on any value between "a" and infinity must equal 1.
Now by using calculus, we can find the value of "a" by solving the equation
=> ∫(a,∞) (12/X³) = 1.
This equation tells us that the total probability of the random variable taking on any value greater than "a" must equal 1.
By solving for "a", we find that it is approximately equal to 2.83.

Answers
To solve the equation 2y^(4) +11y^(3) + 18y" + 4ť' - 8y=0, we can first factor out a common factor of 2y: 2y(y^3 + 5y^2 + 9y + 2ť' - 4) = 0 Next, we can focus on the expression inside the parentheses, which can be written as:
y^3 + 5y^2 + 9y + 2ť' - 4
We can recognize this expression as the polynomial 2r^4 +11r^3 + 18r^2 + 4r – 8 evaluated at r=y-1/2.
So, 2r^4 +11r^3 + 18r^2 + 4r – 8 = (2r - 1)(r + 2)^3.
Finally, we can factor out a common factor of 2 and use the factored form of the polynomial:
2(y-1)(y+2)^3(2y+1) = 0
Therefore, the solutions to the original equation are:
y = 1, -2, -1/2 (multiplicity 3)
To solve the given polynomial equation, we will first rewrite it in a more accurate and coherent form by removing the irrelevant terms:
2y^4 + 11y^3 + 18y^2 + 4y - 8 = 0
We are given a hint that the equation can be factored as:
(2r - 1)(r + 2)^3
Now, we will replace r with y to match the variable in the given equation:
(2y - 1)(y + 2)^3 = 0
Now that we have the factored form of the equation, we can set each factor equal to zero and solve for y:
1) 2y - 1 = 0
2y = 1
y = 1/2
2) (y + 2)^3 = 0
y + 2 = 0
y = -2

a researcher is 95% confident that the interval from 2.9 minutes to 6.83 minutes captures mu the true mean amount of time mice take to complete a maze for a piece of cheese. is it plausible that the true mean number of times for all mice to complete this maze may be less than 7 minutes?
Answers
The correct option is option a) Yes, this is plausible for the population mean because the upper boundary of the 95% confidence interval is below 7 minutes.
A confidence interval is a range of values, derived from a sample of data, that is used to estimate an unknown population parameter. The interval has an associated confidence level, such as 90%, 95%, or 99%, which indicates the level of confidence that the interval contains the true population parameter.
The most commonly used method to calculate a confidence interval is the method of maximum likelihood estimation. The wider the interval, the less certain the estimate, and the narrower the interval, the more certain the estimate.
It is plausible that the true mean number of times for all mice to complete the maze may be less than 7 minutes, as the interval provided by the researcher (2.9 minutes to 6.83 minutes) does not include 7 minutes as an upper bound.
A 95% confidence interval indicates that if the study were to be repeated multiple times, 95% of the intervals created would contain the true mean, so there is a 5% chance that the true mean falls outside of the interval provided.
Therefore, The correct option is option a) Yes, this is plausible for the population mean because the upper boundary of the 95% confidence interval is below 7 minutes.
