How do I Evaluate f(5).

Answer:

12+-8=4

Step-by-step explanation:

this would be that same as 12-8=4, just keep the numbers but flip the negative into a positive number then change the equation into a subtraction problem if this confuses you.

Answer:

А. The solution to this system is nonviable because it results in a fractional number of tickets.

Step-by-step explanation:

Let x represent the number of adult tickets, y represent the number of child ticket and z represent the number of senior ticket.

Since the number of purchased ticket is 17, hence:

x + y + z = 17         (1)

The total cost of tickets is $141.50, hence:

10x + 7y + 8.5z = 141.5       (2)

they are purchasing 2 more senior tickets than adult tickets, therefore:

x = z + 2        (3)

Solving equation 1 2 and 3 simultaneously gives:

x =17/3, y = 23/3, z = 11/3

Therefore the solution to this system is nonviable because it results in a fractional number of tickets.

Answer:

True : It is an example of a continuous variable

Step-by-step explanation:

Numerical variables acn be classed as either being discrete or continuous based on whether the values in the data set are finite and countable or not.

Discrete variables are characterized by possessing a finite number of possible values which are countable and usually do not involve decimal numbers in between successive whole numbers.

On the other hand continuous variables are non finite and usually contains a lot of points in between possible whole numbers such as in the scenario above, the race time for the students take up any number within minutes, seconds and milliseconds. Hence, making the possible Numner of values impossible to predict or state.

Irrational Number

Step-by-step explanation:

The irrational numbers are those that cannot be expressed as a ratio of two integers. Examples are as well as the square roots of many other numbers, and special numbers like e and π. It turns out that there are as many irrational numbers as rational. Irrational numbers have no exact decimal equivalents.

Answer:

56 possible different subcommittees

Step-by-step explanation:

This is a combination problem.

In combination probability, the formula is;

nCr = n!/((n - r)! × r!)

Now, out of the 8 members on the board of directors, they now want to form a subcommittee of 3 members.

Thus, the different subcommittees possible is given by;

8C3 = 8!/((8 - 3)! × (3!)) = 56

Thus, there are 56 possible different subcommittees

Answer:

[tex]WX = 83[/tex]

[tex]WY = 119[/tex]

[tex]XY = 36[/tex]

Step-by-step explanation:

Given

[tex]WX = 3y + 11\\WY = 6y - 25\\XY = y + 12[/tex]

Required

Determine the values of WX, XY and XY

Since X is between W and Y, we have:

[tex]WY = WX + XY[/tex]

[tex]6y - 25 = 3y + 11 + y + 12[/tex]

Collect Like Terms

[tex]6y - 3y - y = 25 + 11 + 12[/tex]

[tex]2y = 48[/tex]

Solve for y

[tex]y = 48/2[/tex]

[tex]y = 24[/tex]

Substitute 24 for y in

[tex]WX = 3y + 11\\WY = 6y - 25\\XY = y + 12[/tex]

[tex]WX = 3 * 24 + 11[/tex]

[tex]WX = 83[/tex]

[tex]WY = 6 * 24 - 25[/tex]

[tex]WY = 119[/tex]

[tex]XY = 24 + 12[/tex]

[tex]XY = 36[/tex]

  your marked choice is correct: x = e

Step-by-step explanation:

For the line to go through the origin, the ratio of ln(x) to x at the point must equal the slope at the point.

The slope of ln(x) is 1/x, so we require ...

Answer:

Tanya's height at age of 9 is 53.75 inches

Step-by-step explanation:

Tonya's age (yr.)     Tonya's height (in.)

3                                        36.8

4                                         40

5                                       41.25

6                                        45

7                                        48.0

8                                       51.5

Tanya's height at the age of 8 = 51.5

We are given that Tonya grew 2.25 more inches before her 9 year height was recorded.

So, Tanya's height at age of 9 = 51.5+2.25

Tanya's height at age of 9 =53.75 inches

Hence Tanya's height at age of 9 is 53.75 inches

Answer:

The simplified form of the compound fractional expression is [tex]\frac{x^2(y-1)}{y^2(x-1)}[/tex].

Step-by-step explanation:

Simplify the fraction as shown:

[tex]\dfrac{x-\frac{x}{y} }{y-\frac{y}{x} }[/tex]

Take the LCM.

[tex]\dfrac{\frac{xy-x}{y} }{\frac{xy-y}{x} }[/tex]

Simplify,

[tex]\frac{xy-x}{y} \times\frac{x}{xy-y}[/tex]

[tex]\frac{x^2(y-1)}{y^2(x-1)}[/tex]

Hence, the simplified form of the compound fractional expression is [tex]\frac{x^2(y-1)}{y^2(x-1)}[/tex].

Answer:

The area is changing at 2 m²/d.

Step-by-step explanation:

The area of a rectangle is given by:

[tex] A = l*w [/tex]

Where:

l is the length

w is the width

We have that the length is increasing at a rate:

[tex] \frac{dl}{dt} = 1 \frac{m}{d} [/tex]

And the width is decreasing at a rate:

[tex]\frac{dw}{dt} = -2 \frac{m}{d}[/tex]

The change in the rectangle's area is the following:  

[tex] \frac{dA}{dt} = w\frac{dl}{dt} + l\frac{dw}{dt} [/tex]

When the length is 8 meters and the width is 18 meters we have:

[tex] \frac{dA}{dt} = 18 m*1\frac{m}{d} + 8 m(-2 \frac{m}{d}) [/tex]

[tex] \frac{dA}{dt} = 18 \frac{m^{2}}{d} - 16 \frac{m^{2}}{d} [/tex]

[tex] \frac{dA}{dt} = 2 \frac{m^{2}}{d} [/tex]

Therefore, the area is changing at 2 m² per day.

Answer: 1/3^7

Step-by-step explanation:

Answer:

1/4

Step-by-step explanation:

15 - 3 = 12

3 : 12

1 : 4

In its most basic form, the debate team's male-to-female ratio is 1/4.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

given, There are 15 students on the debate team. Of these, 3 are boys.

Since there are 3 boys out of 15

Thus,

Number of girl = 15 - 3

Number of girls = 12

Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B.

thus,

The ratio of boys to girls = 3/12

the Ratio of boys to girls = 1/4

therefore, the ratio of boys to girls on the debate team in simplest form is 1/4.
