Part B. Calculate the height of the building to the nearest tenth of a foot?
Explain your process for arriving at the answer.
a. The diagram that represents this situation is given by the image shown at the end of the answer.
b. The height of the building is of: 33.4 feet.
What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.As shown by the diagram given at the end of the answer, this situation is represented by a right triangle in which:
There is an angle of 24º.The adjacent side to the angle is of 75 feet.The height of the building is of x feet.Then the height of the building is calculated as follows:
tan(24º) = x/75
x = 75 x tangent of 24 degrees
x = 33.4 feet. -> height of the building.

An electrician need to run a cable from the top of a 68-foot tower to a tranmitter box located 51 feet away from the bae of the tower. Fidn how long he hould cut the cable
By using Pythagoras' theorem the required length of the cable is 85 feets.
What is Pythagoras' theorem?The square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides, according to Pythagoras' theorem. Perpendicular, Base, and Hypotenuse are the names given to the triangle's sides. The hypotenuse is the longest side in this case because it is opposite the angle of 90°.
What is the name of Pythagoras' formula?The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides of a right-angled triangle. Alternatively, the sum of the squares of a right triangle's two legs equals the square of its hypotenuse.
Given:
Height of the tower = 68 feet = perpendicular
distance of box form tower = 51 feet = base
Let's assume lenght of the cable = L = hypotenous
Acoording to the question by using Pythagoras' theorem,
[tex]hyp^{2}= perpendicular^{2} +base^{2} \\(L)^2 = (68)^2 + (51)^2\\L^2 = 4624 + 2601\\L^2 = 7225\\L =\sqrt{7225}\\L = 85 feet[/tex]

What is meant by 6% slope?
6% slope means on a run of 100 units, there is just a 6-unit rise. The basic definition of slope is the gradient or incline of the terrain.
A steep slope is an abrupt incline, and a gentle slope is a gradual incline. The river's route flows between the steep, forested hills and their softer counterparts.
This is accomplished by comparing the vertical and horizontal changes, which are frequently stated as rise/run.
Since "percent" or "%" denotes "out of 100" or "per 100," x% can be expressed as
For instance
You can come across a road sign that says "6% Grade" or "Steep Grade" while driving down a highway. The road's grade is essentially its slope, multiplied by 100.

why is an understanding of the central limit theorem essential to the concepts of estimation an hypothesis testing?
Because it permits one to assume that the sampling distribution of the mean would typically be normally distributed, the central limit theorem is helpful when examining big data sets. This makes statistical analysis and inference simpler.
Hypothesis :
In statistics, hypothesis testing is used to identify the variance in the group of data that results from genuine variation. Based on the presumptions, the sample data are taken from the population parameter. The hypothesis can be divided into many categories. A hypothesis is described in statistics as a formal statement that explains the relationship between two or more variables belonging to the specified population. It aids the researcher in converting the stated issue into an understandable justification for the study's findings. It provides examples of various experimental designs and guides the investigation of the research procedure.

Variance is the anticipated squared variation of a random variable from its population mean or sample mean in probability theory and statistics. Variance serves as a proxy for dispersion, or the degree to which a set of numbers deviates from their mean.
Here, We have
The mean square for error in the ANOVA provides an estimate
ANOVA = Analysis of VarianceThe correct answer is (B)
The mean square for error (MSE) in the analysis of variance (ANOVA) provides an estimate of the variance of an individual treatment average.
Unlike option C which refers to an individual observation,
option B refers to a group of observations that are classified into a single treatment sample.
The MSE measures (gives an estimate of) the variation within this treatment sample. In this case, the variation is in the average or the mean. This could be average texture, average strength, average penetration, etc.

Is the sum of any two whole numbers always a whole number answer it with at least 3 example?
Yes, the sum of 2 whole numbers is always a whole number.
Any number that ranges from 0 to infinity with 1 as the denominator in its smallest form is called a whole number.
For example- 0, 3, 78, 9363, etc.
Now if we take up two numbers say 34 and 78.
34 + 78
= 112
According to the definition of the whole number, we can say that this is a whole number.
Another example can be 0 + 237
The sum is 237

so, the 4th answer option is correct. g(x) is steeper than f(x).
the lines are not parallel, because they do not have the same slope.
they are not perpendicular, because perpendicular slopes turn the y/x ratio upside down AND flip the sign.

Answer:
The conclusion is incorrect because there is exactly one solution to the equation.
Step-by-step explanation:
8x - 12 = 4(12x - 6)
4 x 12x = 48x 4 x -6 = -24
8x - 12 = 48x - 24
Move the terms
8x - 12 - 48x = -24
Move the constant to the right-hand side and change its sign
8x - 48x = -24 + 12
-40x = -24 + 12
-40x = -12
Divide both sides by -40
