The table that represents this relationship regarding the volume is table D.

From the information, the approximate volume in milliliters, m, for a volume of f fluid ounces is equal to 29.57 times the value of f.

Therefore, when f is 1, the millimeters will be:

= 1 × 29.57

= 29.57

When f is 2, the millimeters will be:

= 2 × 29.57

= 59.14

When f is 3, the millimeters will be:

= 3 ×29.57

= 88.71

When f is 4, the millimeters will be:

Step-by-step explanation:

By using the concept of function, it can be calculated that

[tex]f^{-1}(x) = \frac{3x - 4}{6}[/tex]

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here, the function is

[tex]f(x) = 2x + \frac{4}{3}\\[/tex]

Let f(x) = y

[tex]2x + \frac{4}{3} = y\\\frac{6x + 4}{3} = y\\[/tex]

6x + 4 = 3y

6x = 3y - 4

The polynomial in standard form is equal to 2 · x³ + 12 · x² - 64.

Cubic equations have three roots. In this problem we need to derive a cubic equations whose three real roots (r₁, r₂, r₃) and leading coefficient (a) are given. The procedure consists in substituting on factor form of a cubic polynomial and expanding the resulting expression until standard form is obtained.

First, substitute on the factor form of the cubic equation:

y = 2 · (x - 2) · (x + 4)²

Second, expand the polynomial until its standard form is found:

y = 2 · (x - 2) · (x² + 8 · x + 16)

y = 2 · (x³ + 8 · x² + 16 · x - 2 · x² - 16 · x - 32)

y = 2 · (x³ + 6 · x² - 32)

y = 2 · x³ + 12 · x² - 64

The Total Probability is 4/663 and 35/2652

What is Probability?

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. An event's probability is a number between 0 and 1.

Solution:

We know that there are 52 cards in a deck of cards.

So, probability of getting a king = 4/52 = 1/13

And probability of getting a 7 after drawing a king is 4/51,

this is because one card is drawn out from the deck and there are only 51 cards left in the deck.

Total Probability = 1*4/13*51 = 4/663

In the secon case, there are two possibilities,

It can be the kling drawn might be of spade or not

Case 1: When King drawn is of Spade

Probaility of drawing a King of Spade = 1/52

Probability of drawing a Spade after King of Spade is drawn = 11/51

Total Probaility = 1*11/52*51 = 11/2652

Case 2: When King drawn is not of Spade

Probability of drawing a King not of Spade = 2/52

Probability of drawing a Spade after drawing the King = 12/51

Total Probability = 2*12/51*52 = 24/2652

Total Probability of drawing a king and spade = 11/2652 + 24/2652 = 35/2652

If a person deposits $8,000 into a savings account at 6.5% interest compounded quarterly for 12 years, the balance (future value) will be $17,342.70.

The future value is the compounded present value of an investment for a future period.

The future value can be computed using the FV formula, table, or an online finance calculator as below.

N (# of periods) = 48 quarters (12 years x 4)

I/Y (Interest per year) = 6.5%

PV (Present Value) = $8,000

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $17,342.70

Total Interest = $9,342.70

Thus, the future value of a present investment of $8,000 at 6.5% interest compounded quarterly for 12 years is $17,342.70.

The two numbers that are compatible are 0.25 and 8. The property which helps to calculate it is commutative property.

What is the commutative property?

This law merely asserts that while adding and multiplying integers, you can rearrange the numbers in a problem without changing the solution.

Given numerical expression is (0.25 x 12.3) x 8.

First remove the parenthesis from the numerical expression:

(0.25 x 12.3) x 8 = 0.25 x 12.3 x 8

Now apply commutative property:

(0.25 x 12.3) x 8 = (0.25 x 8) x 12.3

Answer:

b=3x+y

Step-by-step explanation:

y=-3x+b

get b by itself on one side

y+3x=b

The rearranged equation, [tex]b = Y + 3x[/tex], allows us to determine the value of b based on the given values of Y and x.

Rearranging an equation involves manipulating the terms and variables in order to isolate a specific variable or simplify the equation. The goal is to rewrite the equation in a different form while maintaining equality.

In the context of solving the equation [tex]Y = -3x + b[/tex] for b, rearranging the equation means moving the terms around so that b is isolated on one side of the equation. This is done by performing inverse operations on the equation.

Starting with [tex]Y = -3x + b[/tex], we want to isolate b. To do this, we need to move the [tex]-3x[/tex] term to the other side of the equation.

By subtracting [tex]-3x[/tex] from both sides, we can eliminate the -3x term on the right-hand side. The equation becomes [tex]Y - (-3x) = b[/tex].

Simplifying further, [tex]Y + 3x = b[/tex]. Now, b is isolated on one side of the equation.

Therefore, the rearranged equation, [tex]b = Y + 3x[/tex], allows us to determine the value of b based on the given values of Y and x.

With 95% confidence, the margin of error is 19.523, population mean is (253.477, 292.523) and the change in cost over the two-year period is 19.21%.

In the given question,

The average cost per night of a hotel room in New York City(y) = $273

Number of rooms in hotel(n) = 45.

The sample standard deviation(s) = $65

(a.) Now finding the margin of error, with 95%(0.95) confidence.

The formula of margin of error is

ME= [tex]z_{\alpha /2}\times \frac{s}{\sqrt n}[/tex]

Now find the value of [tex]z_{\alpha /2}[/tex].

[tex]\alpha[/tex] = 1-0.95

[tex]\alpha[/tex] = 0.05

[tex]\alpha[/tex]/2 = 0.05/2

[tex]\alpha[/tex]/2 = 0.025

Now the value of [tex]z_{\alpha /2}[/tex]

[tex]z_{\alpha /2}=z_{0.025}[/tex]

From the standard table of z is 2.015.

Now putting the value in formula

ME= 2.015 × 65/√45

ME= 2.015 × 65/6.708

ME= 2.015 × 9.689

ME= 19.523

Hence, with 95% confidence, the margin of error is 19.523.

(b) Now finding .the 95% confidence interval estimate of the population mean.

Population Mean = y ± ME

Population Mean = 273 ± 19.523

Population Mean = {(273-19.523), (273+19.523)}

Population Mean = (253.477, 292.523)

(c) Now two years ago the average cost of a hotel room in New York City was $229 then the change in cost over the two-year period is

The change in cost = difference between the cost/old cost

The change in cost = (273-229)/229 *100

The change in cost = 44/229 *100

The change in cost = 0.1921 *100
