Find the length of the toothpick nearest millimeter

The probability that an ace appears at the 9th place, and a queen appears at the 10th place in the deck is 1/221.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given:

The probability that an ace appears at the 9th place, and a queen appears at the 10th place in the deck can be calculated as:

There is a total of 52 cards in a deck and 4 aces and 4 queen cards.

So, the probability is

4/52 * 4/51 = 1/221

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, Angelina spent $23.65 on books and magazines when she went to chapters. She bought a total of 7 items. The books cost $5.95 each and the magazine cost $2.95 each.

Let "b" be the number of total book and "m" be the number of magazine she bought.

Inequality from the given data

m + b = 7

since, Angelina spent $23.65 on books and magazines

thus,

5.95 * b + 2.95 * m = 23.65

from equation 1

5.95b + 2.95(7 - b) = 23.65

5.95b + 20.65 - 2.95b = 23.65

because of PEMDAS

The correct option is Option A: (5h^2)^3 + (3k)^3

The total number of cubic units that the cube totally occupies is the definition of a cube's volume. A cube is a solid three-dimensional object with six square faces. Volume is simply the total amount of space an object takes up. A thing with a bigger volume would take up more room.

Total Volume = V₁ + V₂

V₁ = Volume of Cube 1

V₂ = Volume of Cube 2

Volume of Cube = (Side Length)³

V₁ = (5h²)³

V₂ = (3k)³

∴ Total Volume = (5h²)³ + (3k)³

And this cannot be simplified further.

Answer:

y = -2x + 13

Step-by-step explanation:

In order to write an equation of the line in slope-intercept form, we first have to look at the equation:

y = mx + b

We know that m represents slope, and b represents the y-intecept, in other words, what y is equal to when x is equal to zero.

We already have y and x, (4,5), and the slope of the line, since the two lines are parellel, they share the same slope. So now, we have to pulg those values into the equation and solve for b:

(4,5)

y = 5

x = 4

m = -2

y = mx + b

(5) = (-2)(4) + b

5 = -8 + b

13 = b

So, equation of the line in slope-intercept form that passes through point (4, 5), is y = -2x + 13

The formula for compound interest is: A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment (the amount Alex has at the end of 7 years)

P = the initial investment (£4000)

r = the annual interest rate (x/100)

n = the number of times interest is compounded per year (let's assume it is compounded annually)

t = the number of years invested (7)

Plugging in the given values and solving for x:

5263.73 = 4000(1 + x/100)^7

So x = ((5263.73/4000)^(1/7))-1*100

x = 6.33% (approximately)

So, the interest rate is 6.33%.

b) Nearly normal according to the central limit theorem.

c) 0.0901 = 9.01% probability that the average cable service paid by a sample of cable service customers exceeds $170 in the central limit theorem.

Normal probability distribution:

The normal probability distribution, discovered by Abraham De Moivre in 1733, approximates the binomial probability distribution when a particular experiment has a very large number of trials. In 1774 Laplace studied the mathematical properties of the normal probability distribution. By historical error, the discovery of the normal distribution was attributed to Gauss, first mentioned in his 1809 paper. In the 19th century, many scientists discovered that measurement errors in a particular experiment followed a pattern (usual error curve). ), which was very well approximated by this probability distribution.

Central Limit Theorem:

The central limit theorem is a statistical theory that for large sample sizes with finite variance, samples are normally distributed and the mean of the sample is approximately equal to the mean of the entire population.

According to the Question:

The average monthly charge is $142 with a standard deviation of $29.

This is μ = 142 and σ = 29

Part a:

The mean and standard deviation of the sampling distribution of x to show your research and support your argument:

According to the Central Limit Theorem

The mean is 142 $

The standard deviation is s = [tex]\frac{29}{\sqrt{1500} }[/tex] = 0.7488

Part b:

Shape of sampling distribution of X.

Due to the large sample size, the shape of the sample distribution is almost normal. According to the central limit theorem, which states that the sampling distribution converges to the normal distribution as the sample size increases. Mean ~ N(142, 0.749²)

Part C:

The probability that the average cable service paid by a sample of cable service customers exceeds $170.

Therefore, by the central limit theorem, the p-value of Z when X= 170

                         Z =  x - μ/ σ

By the Central Limit Theorem:

   Z = 170 - 142 / 0.7488

      = 28/ 0.7488
