The value 5 is a solution to the inequality x + x > 8 from the set {2, 3, 4, 5}.

What is meant by set?

In mathematics, a set is a collection of distinct objects or elements that share a common characteristic or property. Sets can be composed of numbers, letters, symbols, or even other sets.

To solve the inequality x + x > 8, we can simplify the left-hand side by combining like terms:

2x > 8

Then, we can solve for x by dividing both sides by 2:

x > 4

So any value of x greater than 4 would be a solution to the inequality.

From the set {2, 3, 4, 5}, the only value that satisfies this inequality is 5, since 5 is greater than 4:

5 + 5 = 10 > 8

Therefore, the value 5 is a solution to the inequality x + x > 8 from the set {2, 3, 4, 5}.

Let's define the following variables first.

A = number of tickets sold for adults

C = number of tickets sold for children

From the question, we can say that or form the following equations:

1. A + C = 790 tickets

2. $7A + $4C = $4, 390

The first equation can also be written as A = 790 - C. We can use this equation and replace "A" in the second equation.

From that, we can solve "C" by solving the equation formed above.

Therefore, 380 tickets for children were sold.

Since there are 790 tickets in total that are sold and 380 tickets for children were sold, we can say that 410 tickets for adult was sold.

To find the new coordinates of the points after Louis multiplied each x-coordinate and y-coordinate of triangle ABC by -2, we can use the following formulas:

New x-coordinate = -2 * old x-coordinate

New y-coordinate = -2 * old y-coordinate

Let's apply these formulas to each point in triangle ABC:

Point A: (-3, 4)

New x-coordinate of A = -2 * (-3) = 6

New y-coordinate of A = -2 * 4 = -8

New coordinates of A: (6, -8)

Point B: (1, 1)

New x-coordinate of B = -2 * 1 = -2

New y-coordinate of B = -2 * 1 = -2

New coordinates of B: (-2, -2)

Point C: (5, -2)

New x-coordinate of C = -2 * 5 = -10

New y-coordinate of C = -2 * (-2) = 4

New coordinates of C: (-10, 4)

Therefore, the new coordinates of the points after Louis multiplied each x-coordinate and y-coordinate of triangle ABC by -2 are:

A: (6, -8)

The two numbers in this problem are given as follows:

x = -11, y = -23.

The two numbers are obtained solving a system of equations, for which the variables are given as follows:

x and y.

The sum of two numbers is -34, hence:

Replacing the second equation into the first, the value of x is given as follows:

x + x - 12 = -34

2x = -22

x = -11.

Hence the value of y is given as follows:

The order pair of point B is (1.75,1.25).

What is order pair?

 A pair that has two values stated in a specific order between parenthesis is known as an ordered pair. It is made up of the x coordinate (abscissa) and the y coordinate (ordinate). For greater visual comprehension, it helps to locate a point on the Cartesian plane. Two numbers in a specific order. Usually, parentheses are used to write this: (12,5)

This can be used to display a graph's position where the "x" (horizontal) value appears first and the "y" (vertical) value appears second.

(12,5) is therefore 12 units down and 5 units up.

Here the given point B is,

coordinate value of x axis= 1.75

coordinate value of y axis = 1.5

Then the order pair of point B is,

=> (x,y) =(1.75,1.5)

The unit of measurement after standardization of a left-skewed data set of hummingbirds' beaks lengths would be "standard deviations above the mean".

To answer your question, after standardizing the lengths of hummingbirds' beaks in a left-skewed data set, the best unit of measurement to describe their lengths would be "standard deviations above the mean."

This is because standardization involves subtracting the mean of the data set from each value and dividing the result by the standard deviation. This process results in a new set of values that are expressed in terms of standard deviations from the mean. Therefore, the unit of measurement is no longer in millimeters or any other physical unit, but in standardized units.
Standardizing the data allows for easier comparison by converting the original measurements to units of standard deviations from the mean.

The probability that a man will test positive on two successive tests if he has the disease 81%.

In mathematical terms, probability can be represented as the ratio of the number of favorable outcomes to the number of possible outcomes. The formula for probability is as follows:

P(E) = n(E) / n(S)

Where:

P(E) is the probability of event E occurring

n(E) is the number of favorable outcomes for event E

n(S) is the number of possible outcomes in the sample space S

Let's assume the probability of a man testing positive for a disease if he has it is represented by the symbol "P".

If the tests are independent, meaning that the outcome of one test does not affect the outcome of the other, then the probability of a man testing positive on two successive tests can be calculated as the product of the probabilities of each individual test.

Therefore, the probability of a man testing positive on two successive tests if he has the disease is P * P, or P².

If the probability of a man testing positive for a disease if he has it is 90%, represented by P = 0.9, then the probability of him testing positive on two successive tests is 0.9 * 0.9 = 0.81, or 81%.

Step-by-step explanation:

The minimum requiremenet is 56 g, so set 13x greater than 56 g.

The area under the standard normal curve to the left of z = 2.06 is approximately 0.9803.

The normal distribution function, also known as the Gaussian distribution or bell curve, is a probability distribution that is symmetric, bell-shaped, and continuous. It is defined by two parameters: the mean (μ) and the standard deviation (σ).

The normal distribution is widely used in statistics and probability theory due to its many desirable properties and its applicability to various natural phenomena. It serves as a fundamental distribution for many statistical methods, hypothesis testing, confidence intervals, and modeling real-world phenomena.

To find the area under the standard normal curve to the left of z = 2.06, you can use a standard normal distribution table or a calculator with a normal distribution function. The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.

Using a standard normal distribution table, the area to the left of z = 2.06 can be found by looking up the corresponding value in the table. However, since the standard normal distribution table typically provides values for z-scores up to 3.49, we can approximate the area using the available values.

The closest value in the standard normal distribution table to 2.06 is 2.05. The corresponding area to the left of z = 2.05 is 0.9798. This means that approximately 97.98% of the area under the standard normal curve lies to the left of z = 2.05.

Since z = 2.06 is slightly larger than 2.05, the area to the left of z = 2.06 will be slightly larger than 0.9798.

Therefore, rounding the answer to four decimal places, the area under the standard normal curve to the left of z = 2.06 is approximately 0.9803.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's break this problem down step by step.

Start by defining a variable to represent the unknown number. Let's call it "x".

Translate the given sentence into an inequality:

"The sum of a number and 19" means "x + 19"

"is at least" means "≥"

"8.2" means "8.2"

So the inequality is:

x + 19 ≥ 8.2

Solve the inequality for x:

x + 19 ≥ 8.2

Subtract 19 from both sides:

x ≥ 8.2 - 19

Simplify:

x ≥ -10.8

So the solution is:

x ≥ -10.8

This means that any number that is greater than or equal to -10.8 will make the original sentence true.
