The total area under a probability distribution equals 1.
A.) True
B.) False
This is true because a probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.
The area under the probability distribution is a measure of the probability of all the possible outcomes. Since the sum of all the probabilities of all the possible outcomes must be 1, the total area under the probability distribution must also be 1. This is because the probability of an event happening is the area under the curve of the probability distribution at that event. Thus, the total area under the probability distribution must always equal 1.
This is true because a probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.

Solve. -4 3/4 = x - 1 1/5 QUICK!!!
Answer:
\(x = \frac{-49}{20}\)
Step-by-step explanation:
\(-4\frac{3}{4} = x - 1\frac{1}{5}\)
\(\frac{-4*4+3}{5} = x - \frac{-1*5+1}{5}\)
\(\frac{-13}{4} = x - \frac{4}{5}\)
\(x = \frac{-13}{4} + \frac{4}{5}\) (collecting like terms to one side)
\(x = \frac{(-13*5) + (4*4)}{4*5}\)
\(x = \frac{-65+16}{20} \\\)
\(x = \frac{-49}{20}\)
Balena has a garden in the shape of a circle of radius 10 m.
He is going to cover the garden with grass seed to make a lawn.
Grass seed is sold in boxes.
Each box of grass seed will cover 46 m' of garden.
Balena wants to cover all the garden with grass seed.
Work out an estimate for the number of boxes of grass seed Balena needs.
Show your working out.
Answer:
7
Step-by-step explanation:
→ Work out area of circle
π × 10² = 100π = 314.159 (3 decimal places)
→ Divide area of circle by box area
314.159 ÷ 46 = 6.8295
→ Round answer as you can't get a decimal of a box
7
The area of a circle is given as πr².
The number of boxes of grass seeds required to cover the garden is 9 boxes.
What is a circle?A circle is a round-shaped figure that has no corners or edges.
The area of a circle is given as:
Area = πr²
We have,
The radius of the circle = 10 m
Area of the garden:
= πr²
We can take,
π = 22/7 = 3.14
= 3.14 x 10 x 10
= 314 m²
The area of a box of grass seeds:
= 46 m²
The number of boxes of grass seeds to cover the garden area:
= 314 / 46
= 6.8 boxes
Thus,
The number of boxes of grass seeds required to cover the garden is 9 boxes.

use the definition of the matrix exponential, given below, to compute eat. for any n × n matrix a, eat = i at a2 t2 2! ak tk k! = [infinity] ak tk k! k=0 . a = 0 0 0 5 0 0 7 1 0
To compute the matrix exponential eat, we can use the definition that involves the power series expansion. The matrix a is given as a 3x3 matrix with specific values. By plugging the matrix into the power series expansion formula, we can calculate the matrix exponential eat.
The matrix exponential eat can be calculated using the power series expansion formula: eat = I + at + (1/2!)a2t2 + (1/3!)a3t3 + ... + (1/n!) and. Here, a is an n × n matrix and t is a scalar representing time. In this case, the matrix a is given as a 3x3 matrix with values 0 0 0 5 0 0 7 1 0. To compute eat, we can plug the matrix into the power series expansion formula and calculate each term.
The first term in the power series expansion is identity matrix I, which is a 3x3 matrix with diagonal elements equal to 1 and all other elements equal to 0. The second term is at, which is obtained by multiplying the matrix a by the scalar t.
The third term is (1/2!)a2t2, where a2 is obtained by squaring the matrix a and multiplying it by (1/2!)t2. We can continue this process for higher terms, calculating (1/n!) Rankin for each term. By summing up all these terms, we can obtain the matrix exponential eat. It's important to note that calculating the matrix exponential can be computationally intensive, especially for larger matrices. However, by using the power series expansion formula, we can approximate the matrix exponential and obtain an expression for eat in terms of the matrix a and the scalar t.

normal approximation for binomial distribution
when n is large we can use this to determine probabilities for binomial settings
In mathematical terms, if X is the sum of successes in n different Bernoulli trials, and p is the likelihood of success in each trial, then X may be represented as a normal distribution with mean increasing as n rises.
μ = np
variance σ^2 = np(1-p)
What is binomial distribution?The binomial distribution is a discrete probability distribution that produces just two outcomes in an experiment: success or failure. In a binomial distribution, the chance of success must remain constant during the trials under consideration. For example, because there are only two possible outcomes when tossing a coin, the chance of flipping a coin is 1/2 or 0.5 for each experiment we do.
Here,
When the sample size (n) is high, the distribution of the total of successes (k) in n separate Bernoulli trials approaches a normal distribution, according to the normal approximation for the binomial distribution.

the pages per book in a library are normally distributed with a population standard deviation of 45 pages and an unknown population mean. a random sample of 15 books is taken and results in a sample mean of 305 pages. what is the correct interpretation of the 99% confidence interval? select the correct answer below: we estimate that 99% of the books in the library have between 275 and 335 pages. we estimate with 99% confidence that the sample mean is between 275 and 335 pages. we estimate with 99% confidence that the true population mean is between 275 and 335 pages.
Therefore, the 99% confidence interval for the population mean is 305 - 30 to 305 + 30, which is between 275 and 335 pages.
The correct interpretation of the 99% confidence interval is that we estimate with 99% confidence that the true population mean is between 275 and 335 pages. This is because the confidence interval is based on the sample mean and the standard deviation of the sample, and it provides a range of values within which we can be reasonably confident that the true population mean lies. The fact that the sample was randomly selected helps to ensure that the estimate is representative of the overall population of books in the library. The population standard deviation of 45 pages is used to calculate the standard error of the mean, which in turn is used to construct the confidence interval.
We estimate with 99% confidence that the true population mean is between 275 and 335 pages.
Explanation:
1. A random sample of 15 books is taken from the library.
2. The sample mean (305 pages) is calculated from the random sample.
3. The population standard deviation is given as 45 pages.
4. To construct a 99% confidence interval for the population mean, we need to use the standard deviation and the sample mean.
5. The formula for the margin of error in a confidence interval is: Margin of Error = Z-score * (Standard Deviation / \(\sqrt{SampleSize}\))
6. For a 99% confidence interval, the Z-score is approximately 2.576.
7. Margin of Error = 2.576 * (45 / √15) ≈ 30
8. The confidence interval for the population mean is: (Sample Mean - Margin of Error) to (Sample Mean + Margin of Error)
9. Therefore, the 99% confidence interval for the population mean is 305 - 30 to 305 + 30, which is between 275 and 335 pages.

the correct interpretation of the 99% confidence interval is:
"We estimate with 99% confidence that the true population mean is between 275.08 and 334.92 pages."
Based on the given information, we can calculate the 99% confidence interval for the true population mean of pages per book in the library.
Here are the steps to calculate the confidence interval:
Identify the given information:
population standard deviation \((\sigma) = 45\) pages, sample size \((n) = 15\) books, and sample mean \((\bar x) = 305\) pages.
Calculate the standard error (SE) of the sample mean:
\(SE = \sigma / \sqrt n = 45 / \sqrt 15 \approx 11.62.\)
The critical value (z) for a 99% confidence level:
\(z \approx 2.576\) (from a standard normal distribution table or using a calculator).
Calculate the margin of error (ME):
\(ME = z \times SE \approx 2.576 \times 11.62 \approx 29.92.\)
Determine the confidence interval:
\((\bar x - ME, \bar x + ME) = (305 - 29.92, 305 + 29.92) \approx (275.08, 334.92).\)

Based on records from the past several seasons the probability of the Madison Math Team winning a competition is p(win)-0.875
If they compete in 24 competitions, how many will they win?
Answer:
They will win 21 games
Step-by-step explanation:
Here, we want to get the number of possible wins
From the question, we have it that the probability that the team will win is 0.875
Now, out of the 24 games, we simply have to multiply their winning probability by the number of games
We have this as;
0.875 * 24 = 21
Hence, out of the 24, 21 will result in a win

Jim takes an hour to fold the weekly washing for his family. His older sister Sara can do the same job in half the time. How many minutes would it take them to fold the washing together if they continue to fold at their own rates?
Answer:
Let's start by finding out how long it takes Jim to fold the washing in minutes. Since there are 60 minutes in an hour, Jim takes 60 minutes to fold the washing. Sara can do the same job in half the time, so she takes 30 minutes to fold the washing. To find out how long it would take them to fold the washing together, we can use the formula: Time = (Work) / (Rate) In this case, the "work" is folding the washing, and the "rate" is how long it takes each person to do the work. We can add their rates together to get the combined rate: Combined rate = Jim's rate + Sara's rate Combined rate = 1/60 + 1/30 To add these fractions, we need to find a common denominator, which is 60:

When a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. Write an
equation and solve it to find the value of n.
Show work plsss
The equation is 4(n - 7) = 88 and the value of n is 29.
What is an Equation?An equation basically means a mathematical statement including variables and operator that shows that two expressions are equal. Any equation can be solved using PEMDAS rule. where P stands for Parenthesis, E stands for Exponents, D stand for Divide, M for Multiplication, A for Addition and S for Subtraction.
If the number n is decreased by 7, that means n - 7.
Then the result is multiplied by 4, so 4(n - 7).
The product is equal to 88, so the equation is,
4(n - 7) = 88
Now, solving the equation
4(n - 7) = 88
4n - 28 = 88
4n = 116
n = 29
Therefore, the equation is 4(n - 7) = 88 and the value of n is 29.

A dramatic change in look or form is referred to as a transformation and the transformation of points (0, 1) to D5 o R270° is (270, -4).
What is transformation?A transformation is a significant alteration in appearance or form.
Your life may change as a result of a significant occasion like earning your driver's license, enrolling in college, or getting married.
A dramatic, drastic shift is called metamorphosis.
In the standard nomenclature, a function maps a number to a number, but a transform maps a function to a function.
This distinction is illogical and inaccurate.
So, fL2(R), to use an example, is a function (kind of), since f is sort of a numerical value for each xR. (x).
So, we have the points:
(0, 1)
Then, the transformation is D5 o R270°.
If D5 signifies "down 5" and R270," respectively.
then, subtract 5 from 1 and add 270 to get:
(270, -4)
Therefore, a dramatic change in look or form is referred to as a transformation and the transformation of points (0, 1) to D5 o R270° is (270, -4).
