The required standard deviation of the given data is 54.6.

To find the sample standard deviation for the weights of the offensive linemen, we first need to calculate the mean of the sample and then use that to find the variance and standard deviation.

Mean:

The mean (μ) is the sum of all the values in the sample divided by the number of values in the sample. In this case, the mean is:

(359 + 297 + 350 + 254 + 312 + 250 + 359 + 253 + 254 + 326 + 254 + 331) / 12 = 298.75

Variance:

The variance (σ²) is a measure of the spread of the data. It is calculated as the sum of the squared deviations of each value from the mean divided by the sample size minus one. In this case, the variance is:

( (359 - 298.75)² + (297 - 298.75)² + (350 - 298.75)² + (254 - 298.75)² + (312 - 298.75)² + (250 - 298.75)² + (359 - 298.75)² + (253 - 298.75)² + (254 - 298.75)² + (326 - 298.75)² + (254 - 298.75)² + (331 - 298.75)² ) / (12 - 1) = 2987.5

Standard Deviation:

The standard deviation (σ) is the square root of the variance. In this case, the standard deviation is:

√2987.5 = 54.59

Therefore, the sample standard deviation of the weights of the offensive linemen is 54.59 pounds.

What is the parametric equation?

The parametric equation of a curve is a representation of the curve in terms of one or more independent variables (known as parameters), usually represented as t. Each parameter value t corresponds to a unique point (x, y, z) on the curve.

For the given curve, the intersection of the cylinder x²  + y² = 81 and the surface z = 6xy can be found by setting the equation of the cylinder equal to the equation of the surface and solving for x, y, and z in terms of a single parameter t.

Starting with the cylinder: x²  + y² = 81, we can parameterize x and y as follows:

x(t) = 9cos(t)

y(t) = 9sin(t)

Substituting these expressions into the equation of the surface:

z(t) = 6x(t)y(t) = 6 * 9cos(t) * 9sin(t) = 54sin(t)cos(t)

So, the parametric equations of the curve given by the intersection of the cylinder x² + y² = 81 and the surface z = 6xy are:

x(t) = 9cos(t)

y(t) = 9sin(t)

z(t) = 54sin(t)cos(t)

Answer: A linear function is one whose graph is a straight line. Given the linear function B(t) = 45422 + 34.26t, its inverse function can be found by switching the places of x and y and then solving for y.

The inverse function, written in function notation, can be represented as:

B^(-1)(t) = (1/34.26)(t - 45422)

So the inverse of the linear model B(t) = 45422 + 34.26t can be written as B^(-1)(t) = (1/34.26)(t - 45422) in function notation.

Answer:

The expression can be solved using algebraic methods. The result is -(2^7)z^2y^3.

Step-by-step explanation:

The solution to the equation 4/(9)((3/2)z^2y^3)^5 is y^15z^10. This can be solved by using the steps of algebraic manipulation. First, the parentheses can be simplified by multiplying the numerator and denominator together, resulting in 4/27z^2y^3. Then, the exponent can be applied to both terms, resulting in y^15z^10. Finally, this answer can be checked by substituting it into the original equation and verifying that it is true.

Answer: In a triangle, the medians divide the triangle into six smaller triangles with equal area. This can be proven using the fact that the medians of a triangle are concurrent, meaning they all intersect at a single point called the centroid.

Let's assume that AD = 2BE, then the area of △ADG is equal to four times the area of △BEG. This can be expressed as follows:

Area(△ADG) = 4 * Area(△BEG)

Since GD is one of the medians, it must be equal to one-third of AD. So, we can write:

GD = AD/3

Since the area of △ADG is equal to four times the area of △BEG, we can write:

Area(△ADG) = 4 * Area(△BEG)

(2BE)^2/2 * GD / 2 = 4 * BE^2/2 * EG / 2

Expanding and simplifying the above equation gives us:

BE^2 * GD / 2 = 4 * BE^2/2 * EG / 2

And, finally, dividing both sides of the equation by BE^2/2, we get:

GD = 1/3 * AD

This result holds true regardless of the relative lengths of AD and BE. Hence, the conclusion that GD = 1/3 AD is always true for any triangle △ABC where AD and BE are medians.

The class limit or the Class width is 6.

Data scattering is indicated by a measure of dispersion. It provides a clear picture of their distribution while explaining the discrepancy between the data from different sources. The measure of dispersion illustrates and provides information on the range and centre value of a single item.

Dispersion, then, is the degree to which values in a distribution deviate from the distribution's mean. It offers us a sense of how different each item is from the main value and from one another.

Arrange the data in increasing order:

54  55  55  55  56  60  60  64 65  69  70  70  71  72  75  75  77  78  79  80  80  85  88  88 88  90 100 102 105

Class width = range/no of classes

No of classes=9

The height of the mountain above the level plain is 4465.2 feet

An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either  be linear, quadratic, cubic, depending of the degree of the variable.

Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.

Let h represent the height of the mountain. Let d represent the distance from the plain to the mountain base

Using trigonometric ratio:

tan(32) = h/d

h = d * tan(32)

Also:

tan(36) = h / (d - 1000)

h = (d - 1000) * tan(36)

Equating:

d * tan(32) = (d - 1000) * tan(36)

d = 7145.9 feet

h = d * tan(32) = 7145.9 * tan(32) = 4465.2 feet
