The formula for the given condition will be x=14t, where x is the number of books that Tea has and t is the number of books that Joseph has.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a whole sentence.

Here,

let x be number of books tea have be x,

Joseph has 14 books.

Tea have t times the book joseph have,

x=14t

The expression for the given condition will be x=14t where Tea have t times the book joseph have and x be number of books tea have.

The conversion of the units is 7 1/2 cup is 112.5 tbsp

From the question, we have the following parameters that can be used in our computation:

convert 7 1/2 cup to tbsp

This can be represented using the following equation

7 1/2 cup = x tbsp

Express as decimal

x tbsp = 7.5 cups

1 cup = 16 tablespoons

So, we have the following representation

x tbsp = 7.5 * 15 tablespoons

Evaluate

x tbsp = 112.5 tablespoons

Hence, the conversion is 112.5 tablespoons

If a quadratic function y = f(x) is plotted on a graph and the vertex of the resulting parabola is (4, 6), the vertex of the function defined as g(x) = f(x +2) - 2 is (2, 4).

In Mathematics, the translation a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.

In Geometry, the function g(x) = f(x + 2) - 2 simply means shifting a graph of the parent function by 2 units to the left and 2 units down.

In this context, we can reasonably infer and logically deduce that the vertex of the image g(x) is given by;

Vertex = (4 - 2, 6 - 2)

Vertex = (2, 4).

Answer:

  {-2, -1, 3}

Step-by-step explanation:

You want the zeros of F(x)=x^3-7x-6.

The signs of the coefficients in order of decreasing degree are +--. There is one sign change, so there is one positive real root.

The rational root theorem tells you any real roots will be divisors of the constant, 6. Hence, we only need to try ±1, ±2, ±3.

The sum of coefficients is 1-7-6 = -12, so x=1 is not a solution. The positive solution is greater than +1.

The sum of coefficients of odd-degree terms is (1 -7) = -6, equal to the sum of coefficients of even-degree terms (0 -6) = -6, so -1 is a root.

The attachment shows F(x) divided by the corresponding factor (x+1) using synthetic division. The quotient is (x² -x -6), so we know the factorization is ...

  F(x) = (x +1)(x² -x -6) = (x +1)(x -3)(x +2)

The zero product rule tells us the roots are ...

  x = {-2, -1, 3}

The graph of the function tells us the same thing.

Additional comment

The constants in the binomial factors of x² -x -6 will be factors of the constant term, -6, that sum to the linear term coefficient, -1. These are -3 and +2.

We like a graphing calculator for finding roots of a cubic and higher-degree polynomials. It will show only the real roots, so more steps are required for complex roots.

Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.

Create a square on paper by using a pencil. Tw dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

A number is divided in division, which is a straightforward procedure. The simplest way to conceptualize it is as a set of objects being distributed among a set of individuals, as in the example given above. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that can be made. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

Answer:

D

Step-by-step explanation:

Option B, option C, and option E are correct because the equation is Negative 3 less than 4.9 times a number, x, which is the same as 12.8.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

The options are:

A: -3 - 4.9x = 12.8

B: 4.9x - (-3) = 12.8

C: 3+ 4.9x = 12.8

D: (4.9 - 3)x = 12.8

E: 12.8 = 4.9x + 3

We have a statement:

A negative 3 less than 4.9 times a number, x, is the same as 12.8.

We can write in a mathematical form:

4.9x - (-3) = 12.8

or

4.9x + 3 = 12.8

or

12.8 = 4.9x + 3

Thus, option B, option C, and option E are correct because the equation is Negative 3 less than 4.9 times a number, x, which is the same as 12.8.

 20                        100% of Ehecatl's old hair

The complete question is added at the end of this solution and as an attachment

From the question, we have the following incomplete table that can be used in our computation:

Length (cm)       Percentage

                          60% of Ehecatl's old hair

                          20% of Ehecatl's old hair

                         100% of Ehecatl's old hair

The first step is to determine the length of her hair before she cut it

The equation to calculate the new length of the hair after the cut is represented as

New length = Length of the hair before it was cut * Percentage

Substitute the known values in the above equation

So, we have the following representations

At 60%: 60% x 20 = 12cm

At 20%: 20% x 20 = 4cm

At 10%: 100% x 20 = 20cm

So, the missing values are 12 cm, 4 cm and 20 cm

A: The percentage of respondents who like hamburgers but dislikes burritos is 46.34%

B: Marginal relative frequency  of all who like hamburgers is 0.65.

C:Lowest joint frequency is of the respondents who like both.

The word "relative" is used to describe how something is being viewed in connection to or in comparison to another event. How frequently an event occurs can be determined by looking at its frequency. On the other hand, relative frequency is a means to compare the frequency of a specific event to all other occurrences.

The ratio of the total number of events occurring in a scenario to the number of times an event occurs is known as relative frequency.

Two facts must be known in order to determine the relative frequency:

>>Number of total events/trials

>>Frequency count for a category/subgroup

                             Like Ham↓  Does Not Like Ham    Total↓

Likes burritos →                 39           38                         77

Does not like burritos →    95           33                        128

Total →                               134           71                        205

So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 39 like Hamburgers.

A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining 33 do not like Hamburgers.

A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.

A:

Total people who liked hamburgers are 134 and those who doesnot like burritos and liked hamburgers are 95 and the total people participated in the survey are 205.

So the percentage of people is [tex]\frac{95}{205}*100[/tex] = 46.34%

B:

The marginal relative frequency is nothing but total people who like hamburgers out of the total respondents.. which is

[tex]\frac{134}{205}[/tex] = 0.65

C:

The category that has lowest joint relative frequency is

Case 1:

Likes both burritos and hamburgers:

[tex]\frac{39}{134}=0.29[/tex]

Likes burritos and dislikes hamburgers:

[tex]\frac{38}{71} = 0.53[/tex]

Likes hamburgers and dislikes burritos:

[tex]\frac{95}{134} = 0.71[/tex]

Who dislike both are:

[tex]\frac{33}{71}=0.47[/tex]

So the category which lowest joint frequency is Likes both burritos and Hamburgers.

A: The percentage of respondents who like hamburgers but dislikes burritos is 46.34%

B: Marginal relative frequency  of all who like hamburgers is 0.65.

C:Lowest joint frequency is of the respondents who like both.
