The given equation solved for z is z = s/(r - 6c⁴)

From the questions, we are to solve the given equation for the specified value

The given equation is

s = zr - 6zc⁴

The specified value is z.

Thus, we are to solve for z.

Solving for z

s = zr - 6zc⁴

First, factor out z

s = z(r - 6c⁴)

Now, divide both sides by r - 6c⁴

s/(r - 6c⁴) = z(r - 6c⁴)/r - 6c⁴

s/(r - 6c⁴) = z

∴ z = s/(r - 6c⁴)

Hence, the given equation solved for z is z = s/(r - 6c⁴)

The properties of the mean and median to determine which

are the correct mean and median for the following histogram. The answer is Mean is 3.5; median is 3.1.

Mean

[tex]\mu=& \varepsilon x \cdot P(x)[/tex]

= 0(0.04)+1(0.08)+2(0.125)+3(0.24) +4(0.15)+5(0.14)+6(0.12)+7(0.05)

= 0+0.08+0.25+0.72+0.6+0.7+0.72+0.35

= 3.42 [Approx: 3.5]

Mean =3.5 of median 3.1.

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data collection is called the mode.

The median is computed by sorting the scores into numerical order, dividing the total by 2, rounding the result up if the number of scores is odd to determine the median position, or by averaging the median position and the position after it, if the number of scores is even.

Answer: x=−32

−1/4x−6=2

Add 6 to both sides:

−1/4x−6+6=2+6

Step-by-step explanation:

Slope = difference in y values / difference is x values

= (1 - (-3)) / (0 - (-1)

So, the equation is

y = 4x + 1.

Answer:

L = 8

w = 3

Step-by-step explanation:

Givens

w = L - 5

L = x

Area = 24

Formula

Area = L * w

Solution

Area = (x) * (x - 5)

24 = x * (x - 5)                      Remove the brackets

24 = x^2 - 5x                       Subtract 24 from both sides

0 = x^2 - 5x - 24                  This will factor

0 = (x - 8)(x + 3)

x + 3 is an extraneous root. You cannot have a length of -3 units no matter what the units are.

x - 8 = 0  

x = 8

Answer

The length = 8

The width is = 8 - 5 = 3  

Using translation concepts, the notation that describes this transformation is:

C. (x,y) -> (x - 8, y - 8).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

Step-by-step explanation:

The volume of a cube that has a total surface area of 54 square millimeters is 27 cubic millimeters

The surface area is given as

A = 54

This is calculated using

A = 6L^2

So, we have

6L^2 = 54

Divide

L^2 = 9

This gives

L = 3

The volume is

V = L^3

This gives

V = 3^3

Evaluate

V = 27

Based on the calculations, the volume of this pyramid is equal to 1440 cm³.

Given the following data:

Length of right triangular base = 9 centimeters and 15 centimeters.

Height of right triangular base = 32 centimeters.

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × b × h

Where:

h is the height of a pyramid.

b is the base area of a pyramid.

According to Descartes' rule of sign,

a. We have 0 or 2 real positive roots for the equation and

b. We have 0 or 2 real negative roots for the equation.

Descartes' rule of sign states that

Since we have the equation 0 = −8x¹⁰ − 2x⁷ + 8x⁴ − 4x² − 1, we now re-write it as a polynomial function. So, it is now f(x) = −8x¹⁰ − 2x⁷ + 8x⁴ − 4x² − 1

To find the number of positive roots, we require the number of sign changes of the polynomial f(x).

Thus, f(x) = −8x¹⁰ − 2x⁷ + 8x⁴ − 4x² − 1

Thus, the coefficients of f(x) are -8, -2, + 8, -4, -1, and we see that there are two sign changes from -2 to + 8 and from + 8 to -4.

Thus, there are 2 or 2 - 2 = 0 real positive roots.

Thus, we have 0 or 2 real positive roots for the equation.

To find the number of negative roots, we thus need to find the number of sign changes of the polynomial f(-x).

Thus, f(-x) = −8(-x)¹⁰ − 2(-x)⁷ + 8(-x)⁴ − 4(-x)² − 1

= −8x¹⁰ + 2x⁷ + 8x⁴ − 4x² − 1

Thus, the coefficients of f-(x) are -8, +2, + 8, -4, -1. We see that there are two sign changes from -8 to + 2 and from + 8 to -4.

Thus, there are 2 or 2 - 2 = 0 real negative roots.

Thus, there are 0 or 2 real negative roots for the equation.

The asymptotes of the graph are vertical asymptotes as; x = 0 and x = -4

The end behavior of the second graph is that as x → ∞, f(x) → -∞ and x → -∞, f(x) → -∞

An asymptote is defined as a line that a curve approaches, as it heads towards infinity. There are three types of Asymptotes namely horizontal, vertical and oblique.

It is called a Horizontal Asymptote when as x goes to positive or negative infinity the curve approaches some constant value.

It is called a Vertical Asymptote when as x approaches some constant value (from the left or right) then the curve goes towards positive or negative infinity

It is called an Oblique Asymptote when as x goes to positive or negative infinity, then the curve goes towards a line y = mx + b

Step-by-step explanation: add all the numbers up and divide them by how many numbers they are

According to the given statement, there are 129 spacy subsets of, such as the empty set.

The correct option is E.

Whole numbers that followed each other with no gaps are known as consecutive integers. For example, the numbers 15, 16, and 17 are all consecutive integers. If is an integer, then the following consecutive integers begin at:,, and so on.

A divider counting argument can be employed because each member of the subgroups must be at least two apart.

We select no more than four numbers first from set 1,2,3,4,5,6,7,8,9,10,11,12. Let's use balls to represent these numbers. There are least two dividers between each of the balls.

So for example, o | | o | | o | | o | | represents {1,4,7,10}.

There must be 2(k - 1) dividers between both the balls in subsets of size k, leaving 12 - k - 2(k - 1) = 12 - 3k + 2 dividers to be placed at k + 1 spots between the balls.

[tex]\left(\begin{array}{c}(12-3 k+2)+(k+1)-1 \\k\end{array}\right)=\left(\begin{array}{c}12-2 k+2 \\k\end{array}\right)[/tex]
