Nina bought 3.45 pounds of walnut.

Nina bought 1.62 pounds more walnut than almonds

Quantity of pecan bought by Nina = 1.725 pounds

Quantity of almonds bought by Nina = 1.83 pounds

The process of comparison of numbers establishes the similarities between two numbers and determines which number is greater, smaller, or equal to another number.

Quantity of walnuts = 2*Quanitity of pecans

= 2*1.725

= 3.45 pounds

So, she bought 3.45 pounds of walnut

Pounds of walnuts bought more than the almonds = Quantity of walnuts bought by Nina - Quantity of almonds bought by Nina

= 3.45 - 1.83

= 1.62 pounds

So, she bought 1.62 pounds more walnuts than almonds

The values of x and XZ, calculated by the given equations are  3 and 30 respectively.

What is a equation?

The equals sign indicates that two expressions in an equation are equal. An equation is a mathematical formula. The meaning of the word equation and its cognates may change a bit depending on the language. An equation is defined as including one or more variables in French, as opposed to English, where an equation is defined as any well-formed formula that consists of two expressions connected by the equals sign.

Given information (and equations) in the question:

Y is between X and Z,

XY = 19,

YZ = 2x+5,

XZ = 6x+12

Since the question say Y is between X and Z, it means:

XY + YZ = XZ

Substituting the values in this equation by the values given in the question:

19 + 2x + 5 = 6x + 12

24 - 12 = 4x

x = 3

putting the value of x in the given equation:

XZ = 6x + 12

XZ = 6(3) + 12

XZ = 18 + 12

XZ = 30

Hence, the values of x and XZ are 3 and 30 respectively.

Solution of Square root,  x² = 30: x = √30 = √30² = 30, x = -√30 = -√30² = 30

Solution of Cube root, x³ = 30: x = ∛30 = ∛30³ = 30, x = -∛30 = -∛30³ = -30

Given,

Square root x² = 30

Then, the value of:

x = √30 = √30² = 30

x = -√30 = -√30² = 30

x = ∛30 = ∛30² = 3.107

x = -∛30 = -∛30² = -3.107

Now,

Cube root, x³ = 30

x = √30 = √30³ = 164.317

x = -√30 = -√30³ = -164.317

x = ∛30 = ∛30³ = 30

x = -∛30 = -∛30³ = -30

Therefore,

Solution of Square root,  x² = 30:

x = √30 = √30² = 30

x = -√30 = -√30² = 30

Solution of Cube root, x³ = 30:

The leading term of the polynomial is [tex]4x^{3}[/tex] and the degree of the polynomial is 3.

A sheet of paper measuring 8.5 inches by 14 inches is currently in our possession. The box's volume V, measured in cubic inches, depends on the side length x, where V (x) = (14-2x)(8.5-2x)(x).

So, we have :

V (x) = (14-2x)(8.5-2x)(x)

[tex]V(x) = (14-2x)(8.5-2x)(x).\\V (x) = (14-2x)(8.5x-2x^{2} )\\V(x) = 4x^{3} -45x^{2} + 119x[/tex]

Thus, the leading term of the polynomial is [tex]4x^{3}[/tex] and the degree of the polynomial is 3.

Now, we have :
[tex]V(x) = 4x^{3} -45x^{2} + 119x\\V(x) = x ( 4x^{2} -45x +119)\\V(x) = x (x-7)(4x-17)[/tex]

Now, For intercepts, V(x) = 0

[tex]V(x) = x (x-7)(4x-17) = 0\\x (x-7)(4x-17) = 0\\\\x = 0, 7, 4.25[/tex]

Now when x = 0, V(x) =0

when x = 7, f(x) = 135

when x = 4.25, f(x) = 252.89

So, the points are (7, 135) and ( 4.25, 252.89)

These points represent the value of x and their corresponding value of V.

y = 6x is proportional.

Proportionality between x and y is defined if there is a constant of proportionality 'k' such that y = kx.

So here, the constant of proportionality in y = 6x is 6.

This equation also means that y varies directly with respect to x and then 6 is the constant of variation.

That is, y is directly proportional to x.

Then a change in y implies a corresponding change in x in the same direction as that of y.

If x increases, then y also increases and if x decreases, then y also decreases.

These changes are related to the constant of proportionality 6.

Correlation is not sensitive to the scale of the data; however, covariance is  sensitive to the scale of the data, so the statement is false.

Covariance is a term used in statistic and regression analysis. Covariance shows how two variables differ.

Covariance is affected by the change in scale, for example if all the value of one variable is multiplied by a constant and all the value of another variable are multiplied, by the same or another constant all together, then the covariance is automatically changed.

Correlation is also a term used in regression analysis and statistics. Correlation shows how two variables are related and therefore not influenced by the change in scale.
