Step-by-step explanation:

The linear equation for this situation is ax + y = Total cost, where is no. of ticket, x = $32.5, is cost of ticket and y = $11.9 is processing fee.

A linear equation is an algebraic equation where the highest exponent of the variable is one. There are linear equations with one, two, or three variables, but not all linear systems have three equations. Typically, a system of linear equations has a single solution, but occasionally there is no solution or an infinite number of solutions.

A relationship in which the value of one variable, say "x," depends on the value of the other variable, say "y," is described by a two variables linear equation. A linear equation's graph will be a straight line if there are only two variables.

Given that cost for 5 tickets is $174.45

Let x be the cost of each ticket and y be the processing fee

5x + y = 174.45

And for the cost for 8 tickets is $271.95

8x + y = 271.95

Subtract the terms

 8x + y = 271.95

- 5x + y = 174.45

 3x + 0 = 97.5

If 3x = 97.5

Then,

x = 97.5/3

x = 32.5

Each ticket costs $32.5 then processing fees

5(32.5) + y = 174.45

y = 174.45 - 162.5

y = 11.95

8(32.5) + y = 271.95

y = 271.95 - 260

y = 11.95

Thus, The linear equation for this situation is ax + y = Total cost, where is no. of ticket, x = $32.5, is cost of ticket and y = $11.9 is processing fee.

Answer: A irregular

b. irregular

c neither

d. Regular

e. regular

Step-by-step explanation: Regular polygons have all sides equal in length but an irregular polygon does not have all sides equal.

Answer:

A: Irregular polygon

B: Irregular polygon

C: Neither

D: Regular polygon

E: Regular polygon

Step-by-step explanation:

To start off with, we can eliminate C for being a polygon (neither), because being a polygon states the shape must be closed with a finite number of line segments (a circle has an infinite amount of line segments).

A regular polygon states that it must have an equal distance on all sides. We can find this by looking at what shapes have a line (which represents that it has the same length) on all sides. The only polygons that fit this requirement are D and E.

From here we can see that the remaining polygons of A and B are in fact irregular polygons by process of elimination.

Answer: The scale of the billboard is 1 foot = 8 inches, so to find the actual height of the woman, we need to multiply the height on the billboard by 8.

8 3/8 feet x 8 inches/foot = 66 inches (8 x 8) + (3 x 8) = 66

So the woman's actual height is 66 inches.

a) The margin of error for the 95% confidence interval is given as follows: $122.4.

b) The 95% confidence interval for the population mean amount spent on restaurants and carryout food is given as follows: ($1,750.6, $1,995.4).

c) The estimate of the total amount spent by Americans of age 50 and over on restaurants and carryout food is between $161,055,200,000 and $183,576,800,000.

d) As the distribution os skewed to the right, the median would be expected to be less than the mean.

The t-distribution is used when the standard deviation for the population is not known, and the bounds of the confidence interval are given according to the following rule:

The value of x is 54/35 when y=12 and z=21. The solution is obtained using the concept of relations and functions.

What is relation and function?

A relation belongs to the Cartesian product's subgroup or just a lot of points (ordered pairs). In other words, the ordered pair collection, where the ordered pair is made up of an object from each set, is used to define the relationship between the two sets.

A function is a special sort of relation (a collection of ordered pairs) that adheres to the rule that every X-value should only be connected with one y-value.

We are given that x varies directly as y and inversely as z.

This means that x ∝ y and x ∝ 1/z

So, x ∝ y/z

=> x = k*y/z  ( k is a constant)

Now, it is given that x = 3 when y = 10 and z = 9

So,

=> 3 = k*10/9

=> k = 27/10

=> x = 27y/10z

When y=12 and z=21,

=> x = 27*12/10*21

=> x = 54/35

Hence, the value of x is 54/35 when y=12 and z=21.

Step-by-step explanation:

the funny thing with equations is we can transform them (as long as we do every operation in both sides), and we can even add them up or subtract from each other to get new equations that are maybe simpler to solve.

to eliminate x i would recommend to multiply the first equation by 4, and the second equation by 5 and then subtract equation 2 from equation 1 (comparable term by comparable term).

5x - 2y = 10

4x - 3y = 15

would then turn into

20x - 8y = 40

- 20x - 15y = 75

------------------------

0 7y = -35

y = -35/7 = -5

now we can pick any original equation to solve for x.

The sum of A and B in the ten digits numbers is 6.

The ten-digit number 3872649A0B is divisible by 36 . Therefore, the ten digit number can divide 36 without any remainder.

Hence, the letters A and B each represent single digit even numbers. Even numbers are numbers that can divide 2 without remainders.

Therefore, let's find the sum of the numbers A and B.

Since, the numbers are single digits and even the numbers are 2, 4, 6 or 8.

Therefore, lets do trial and error to know what will be replaced in the ten digits to divide 36 without remainder.

Therefore, the numbers are 2 and 4.

Where,

A = 2

B = 4

3872649204 ÷ 36 = 107573589

The x-intercepts and the y-intercept of the cubic function f(x) = x³ - 9·x² + 20·x - 12 for which (x - 6) is a factor are;

A function is a rule that uniquely maps each value from the set of input variables to exactly one value in the set of the output variables.

The specified cubic function is; f(x) = x³ - 9·x² + 20·x - 12

A factor of f(x) = x - 6

The x-intercepts are the points on the graph of the function, where the value of the function, f(x) = 0, which are found as follows;

At the x-intercept, f(x) = x³ - 9·x² + 20·x - 12 = 0

x³ - 9·x² + 20·x - 12

Dividing the cubic function by the factor (x - 6), we get;

          x² - 3·x + 2

(x - 6) | x³ - 9·x² + 20·x - 12

   [tex]{}[/tex]       x³ - 6·x²

[tex]{}[/tex]                                      0

The other factor of the cubic function is; x² - 3·x + 2

x² - 3·x + 2 = (x -2)·(x - 1)

Therefore;

f(x) = x³ - 9·x² + 20·x - 12 = (x - 6)·(x - 2)·(x - 1)

From which at the x-intercepts, we get;

f(x) = (x - 6)·(x - 2)·(x - 1) = 0

x = 6, x = 2, and x = 1

The y-intercept are the points the x-values is zero, therefore, at the y-intercepts, we get;

f(0) = 0³ - 9·0² + 20·0 - 12 = -12

let's start with combinations, where the order does not matter - the 4 basis are indistinguishable.

C(5, 4) = 5! / (4! × (5-4)!) = 5! / 4! = 5

that makes sense, of course, as we only need to trace the possibilities for the one empty box : 5 possibilities.

now, the order of the 4 balls matter.

the 4! term in the denominator was actually taking that away, so we need to remove it.

that turns the combinations into permutations, where the order matters.

P(5, 4) = 5! / (5 - 4)! = 5! = 5×4×3×2×1 = 120

Solving by factoring is a strategy for solving a polynomial equation that is in quadratic form. Quadratic form means that the equation is of the form ax^2+bx+c=0, where a,b, and c are real numbers. When factoring, the goal is to express the equation as the product of two simpler equations. To do this, we must factor the quadratic equation into two linear equations, each with a single variable.

For example, consider the equation x^2+3x-4=0. To factor this equation, we can first rewrite it as (x+4)(x-1)=0. This is the same as x+4=0 and x-1=0. We can then solve each of these linear equations to find the solutions. In this case, the solutions are x=-4 and x=1.

Therefore, the strategy of solving by factoring is to rewrite a polynomial equation in quadratic form as the product of two simpler equations, and then solve each of these equations. The solutions to the original equation can then be found by solving each of the linear equations.

Answer: 222 gallons of gasoline to travel 444 miles.

Step-by-step explanation: To find how much gasoline the boat needs to travel 444 miles, we need to use the formula:

distance = rate x time

Where distance is the total distance to be traveled, rate is the distance per unit of fuel (370 miles/185 gallons) and time is the amount of fuel required to travel 444 miles.

So we can calculate the fuel required as:

Fuel = (distance) / (rate)

Fuel = (444 miles) / (370 miles/185 gallons) = 444/ (370/185) = 444/2 = 222 gallons.

So the boat needs 222 gallons of gasoline to travel 444 miles.
