The theater sold 30 adult tickets and 20 children tickets.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

Let, The number of adult tickets be 'x' and the number of children tickets be 'y'.

Therefore, 10x + 5y = 400...(i) and x + y = 50...(ii)×10 ⇒ 10x + 10y = 500...(iii)

Now, Subtracting equation (i) from equation (iii) we have,

5y = 100.

y = 20, and hence x = 30.

So, They have sold 30 adult tickets and 20 children tickets.

Step-by-step explanation:

This is a family of curves represented by the equation:

y = a (x + 4) (x − 2)

Different values of the a coefficient result in different quadratic functions.

The vertex of the parabolas is halfway between the zeros, at x = -1.

y = a (-1 + 4) (-1 − 2)

y = -9a

So to find the value of a, divide the y-coordinate of the vertex by -9. For example, curve A has a vertex at (-1, -3), so the value of the a coefficient is -3 / -9 = ⅓.

A. y = ⅓ (x + 4) (x − 2)

B. y = (x + 4) (x − 2)

C. y = 2 (x + 4) (x − 2)

D. y = -⅓ (x + 4) (x − 2)

The probability at least one of the two television does not work will be 7/9.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Suppose you just received a shipment of ten television. Five of the televisions are defective. If two televisions are randomly selected. Then the probability is given as,

P = (5/10) x (5 / 9) + (5/10) x (5/9) + (5/10) x (4/9)

P = 25/90 + 25/90 + 20/90

P = 70 / 90

P = 7/9

Step-by-step explanation:

First things first, we are rotating about a point so the first we do is the move the clockwise rotation to the origin.

Since a rotation is a rigid transformation, we must move all the other points as well.

So move every point using the rotation vector

R(-6,-8), move every point to

D(1-6,4-8)=D'(-5,-4)

E(5-6,5-8)=E'(-3,-5)

F(4-6,1-8)=F'(-2,-7)

G(0-6,0-8)=G'(-6,-8)

So know since the center of rotation is middle at (0,0) , we can apply the rotation rules

For a 270 clockwise rotation, we apply this rule

(-y,x)

So for the points we know get

D''(5,-4)

E''(3,-5)

F''(2,-7)

G"(6,-8)

Know since we done our rotation, we undo what we did in step 1, we add 6 to the x coordinates and 8nto the y coordinate

D"'(11,8)

E"'(9, 3)

F"(8,1)

G"'(12,0)

So those are our new coordinates.

A hypothesis that there is some sort of relationship between the variables is where scientists start their inquiry. The alternative, or null hypothesis, asserts that there is no such relationship. Although the null hypothesis may not appear fascinating, it is a crucial component of research.

The claim can be supported by either the null hypothesis or the alternative hypothesis. The null hypothesis states that the population proportion is the same as the value specified in the claim. If the null hypothesis is the assertion, then the alternative hypothesis statement is the antithesis of the null hypothesis. A hypothesis is a well-informed, logically-supported guess about the answer to a scientific question. Although it is the experiment's anticipated outcome, it does not constitute experimental proof. The information obtained may or may not be supported, depending on the information received. Simple hypotheses simply state the relationship between two independent and dependent variables.

Answer: The slope of a line in the form y = mx + b can be found by taking the coefficient of x, which is m. In this equation, the slope is not in that form, so we need to isolate y and put it in that form.

Starting with the equation:

3x - 1/2y = 5x + 4

We'll isolate y by subtracting 3x from both sides:

-1/2y = 2x + 4

And then multiply both sides by -2 to solve for y:

y = -4x - 8

So the slope of the line is -4.

What is Word Problem?

A word problem is a mathematical problem that is presented in the form of a story or scenario, often using words and symbols to describe a real-world situation. Word problems require the solver to read and understand the problem, identify the relevant information, translate the information into mathematical expressions or equations, and then solve for the unknown quantity.

Word problems can involve a wide range of mathematical concepts, including arithmetic, algebra, geometry, statistics, and calculus, and are often used to test students' problem-solving abilities and mathematical reasoning skills.

Let's call the price of a senior citizen ticket "s" and the price of a child ticket "c".

From the information given, we know:

3s + c = 38 (equation 1)

3s = 52 (equation 2)

Using equation 2, we can solve for s:

3s = 52

s = 17.33 (rounded to two decimal places)

Now we can substitute this value of s into equation 1 and solve for c:

3s + c = 38

3(17.33) + c = 38

c = 38 - 3(17.33)

c = 5.01 (rounded to two decimal places)

So the price of a senior citizen ticket is $17.33 and the price of a child ticket is $5.01.

There are 5,760 ways to arrange the books on the bookshelf.

A permutation is an ordered arrangement of objects, and it can be calculated as follows:

ⁿPₓ = n! / (n - x)!

where n is the total number of objects and r is the number of objects that we are arranging.

To determine the total number of ways in which we can arrange the books on a bookshelf, we need to first calculate the total number of possible arrangements. We can do this by using the fundamental principle of counting, which tells us that the total number of possible arrangements is equal to the product of the number of ways in which each book can be arranged.

Therefore, the total number of possible arrangements can be calculated as follows:

Total number of possible arrangements = Number of ways to arrange math books × Number of ways to arrange history books × Number of ways to arrange science books

In our case, we have 4 math books, 5 history books, and 2 science books, so we can calculate the number of permutations for each type of book as follows:

Number of ways to arrange math books = ⁴P₄ = 4! / (4-4)! = 4! / 0! = 24

Number of ways to arrange history books = ⁵P₅ = 5! / (5-5)! = 5! / 0! = 120

Number of ways to arrange science books = ²P₂ = 2! / (2-2)! = 2! / 0! = 2

Now, we can substitute these values in the formula for the total number of possible arrangements:

Total number of possible arrangements = 24 × 120 × 2 = 5,760
