you are skiing down a mountain with a vertical height of 2900 feet. the distance from the top of the mountain to the base is 5800 feet. to the nearest degree, what is the angle elevation from the base to the top of the mountain?
Answer:
30°
Step-by-step explanation:
You want the angle of elevation to a point 2900 feet up that is 5800 feet distant on a straight line.
SineThe sine of the angle is the ratio of the height to the straight-line distance.
sin(θ) = h/d = 2900/5800 = 1/2
θ = arcsin(1/2) = 30°
The angle of elevation is 30° from the base to the top.
Answer: When doing a problem like this I always draw an example so I can see it. If you do that you see a right triangle with the hypothenuse, 2500 feet, is the distance from the top to the base. The opposite side is 1250 feet. Then remember sine= o/h, (opposite side over hypothenuse). So divide 1250/2500 and you get .5 Now take your calculator and use "inv" or sin-1 button to get the answer of the angle. x = 30
sinθ 1250/2500 = 1/2; θ = sin-1(1/2) = 30°

The asymptotes for the given function are y = 1 and x = 4 respectively.
What is an asymptote?An asymptote to any function can be defined as a line that touches the graph of the function as the coordinates of the graph approaches infinity.
[tex]\lim_{x \to \infty}[/tex]The given function is R(x) = (x² - 25)/(x² - 8x + 16)
Since, the given function is not defined at x² - 8x + 16 = 0.
The values of x can be found as below,
x² - 8x + 16 = 0
⇒ (x - 4)² = 0
⇒ x = 4
Now, [tex]\lim_{x \to \ 4}} R(x)[/tex] = [tex]\lim_{x \to \ 4}[/tex] (x² - 25)/(x² - 8x + 16)
= -9/0
= -∞
Hence, at x = 4 the function has a y asymptote.
Again, in order to find x asymptotes compute the following limit,
[tex]\lim_{x \to \infty} R(x)[/tex] = [tex]\lim_{x \to \infty}[/tex] (x² - 25)/(x² - 8x + 16)
Apply L' Hospital rule to get,
[tex]\lim_{x \to \infty}[/tex] (x² - 25)/(x² - 8x + 16) = [tex]\lim_{x \to \infty}[/tex] 2x/ (2x - 8)
⇒ [tex]\lim_{x \to \infty}[/tex] 2/2 = 1
Thus, the x asymptote of the function is at y = 1.
Hence, the horizontal and vertical asymptotes of the given function are y = 1 and x = 4 respectively.

The fraction of a box that can be filled with the leftover textbooks is 10.
What is a fraction?
A fraction is a number that represents a part of a whole or a part of a collection. It is written in the form a/b, where a is called the numerator and b is called the denominator.
To find the fraction of a box that can be filled with the leftover textbooks, we need to first find the total number of textbooks that are leftover. We can do this by subtracting the number of fourth-grade textbooks and the number of fifth-grade textbooks from the total number of textbooks that can fit in a box:
Leftover textbooks = (28 textbooks/box) - (125 textbooks) - (191 textbooks)
= 28 textbooks - 125 textbooks - 191 textbooks
= -288 textbooks
Since there are -288 leftover textbooks, we can fill -288/-28 =-288/-28=10 boxes with the leftover textbooks.
Hence, the fraction of a box that can be filled with the leftover textbooks is therefore 10/1 = 10.

The fraction of a box that can be filled with leftover textbooks is 125/7
What is the fraction?
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
To find the fraction of a box that can be filled with leftover textbooks,
we need to first determine the total number of textbooks that will fit in a box.
Since a box can hold 28 textbooks, and the school has bought 125 Fourth Grade math textbooks and fifth-grade math textbooks,
the total number of textbooks the school has is 125 + 125 = 250 textbooks.
To find the fraction of a box that can be filled with leftover textbooks,
we can divide the total number of leftover textbooks by the total number of textbooks that fit in a box.
Since there are 250 leftover textbooks and a box can hold 28 textbooks, the fraction of a box that can be filled with leftover textbooks is 250/28.
Simplifying this fraction, we get:
250/28 = (250/14)/(28/14) = (250/14)/2 = 125/7
Therefore, the fraction of a box that can be filled with leftover textbooks is 125/7.

if the average height of a male in the u.s. is 70 inches and the standard deviation of male heights is 3 inches, what is the probability that a randomly selected male will be between 70 and 73 inches? (assume a normal distribution.)
The probability of men whose height falls between 70 and 73 inches is 0.273. Therefore, the percent of men whose height falls between 70 and 73 inches is 27.3%. Therefore, the solution is 27.3%.
The standard deviation is a quantity that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.
We are informed that the heights of men in the U.S are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. We need to determine the percent of men whose height falls between 70 and 73 inches. We would first evaluate the probability that the height of a randomly selected individual would fall between 70 and 73 inches;
This can be done in stat-crunch;
Click Stat, highlight on Calculators then click Normal
In the pop-up window that appears click Between
Enter the given values of mean and standard deviation; 70 and 3 respectively
Enter the values 70 and 73 in the next set of boxes in that order

The solution is
a) The compound interest for the second period is $ 2.01 and the amount after the second period is $ 404.01
b) The compound interest for the first period is $ 114.125 and the amount is $ 18,374.125
The compound interest for the second period is $ 114.83828125 and the amount after second period is $ 18,488.96
What is Compound Interest?
Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
a)
Let the principal be P = amount after first period = $ 402
Now , the rate of interest r = 6 %
The compound interest is calculated by compounding monthly
Now , the interest for the second period = ( PRT / 100 x 12 )
Substituting the values in the equation , we get
The interest for the second period = ( 402 x 6 x 1 ) / 1200
The interest for the second period = $ 2.01
The amount after the second period = amount after first period + interest for the second period
The amount after the second period = 402 + 2.01
The amount after the second period = $ 404.01
b)
Let the principal be P = $ 18260
The rate of interest r = 2.5 %
The compound interest is calculated by compounding quarterly
Now , the interest for the first period = ( PRT / 4 x 100 )
Substituting the values in the equation , we get
The interest for the first period = ( 18260 x 2.5 ) / 400
The interest for the first period = 45650 / 400
The interest for the first period = $ 114.125
The amount for the first period = 18260 + 114.125
The amount for the first period = $ 18,374.125
Now , the principal for the second period = interest + amount of first period
The principal for the second period = $ 18,374.125
The rate of interest = 2.5 %
The interest for the second period = ( PRT / 4 x 100 )
Substituting the values in the equation , we get
The interest for the second period = ( 18374.125 x 2.5 ) / 400
The interest for the second period = 45935.3125 / 400
The interest for the second period = $ 114.83828125
The amount for the second period = 18,374.125+ 114.84
The amount for the second period = $ 18,488.96

C. 72
D. 18
Answer:
72
Step-by-step explanation:
We are told that line AC divides angle BAE in half or "bisects" it. We are also told that line AD divides angle CAE in half as well. Lastly we are giving the value of angle DAE which is 36.
Since line DA split angle CAE in half and we have half of the value, that means that the measure of angle CAE is 36 times 2 which is 72.
72 happens to be our answer for angle BAC because angle BAC is half of the largest angle BAE, which was divided in two by line AC.

For 10 days that bag will last when Mr. Eder's buys 6 pound bag of dog food, using kg to pound conversion and simple basic arithmetic operation.
How to convert kg to pound ?
We know that 1 Kg = 2.20 pound.
The dog is to eat 1/4 * 2.20 = 0.55 pound food
Weight of bag brought by him = 6 pound
The basic operations are :
Addition : (+) To get sum of two or more values
e.g. a = 3, b = 5
Addition = 3+5
= 8
Subtraction : (-) The result of subtraction is the “difference”
e.g. Subtraction of a and b = a-b
= 3-5
= -2.
Multiplication : (*) The result of multiplication is the “product”
e.g. Multiplication of a and b = 3*4
= 12
Division : (/) The result of division is the “quotient”
e.g. Division of 4 and 2 is = 4/2

In the given question,
P(A)=0.39 P(A) = 0.39 and P(B)=0.42. P(B) = 0.42
(a) We have to find the probability of either A or B occurring.
P(A)=0.39
P(B)=0.42.
Since, events A and B are mutually exclusive
P(A and B) = 0
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.39 + 0.42 - 0
P(A or B) = 0.81
Probability of either A or B occurring is = 0.81
(b) Now we have to find the probability that neither A nor B will happen.
P(A or B) = 0.81

do you need to perform a post hoc on an anova that has three levels and has significant findings for that factor?
Yes, a post hoc test should be performed after an ANOVA with three or more levels if the ANOVA finds a significant result.
Post hoc tests are used to determine which specific levels within the factor are responsible for the significant result.
1. An ANOVA is performed to test if there is a significant difference between the means of three or more levels of a factor.
2. If the ANOVA finds a significant result, then a post hoc test should be performed to determine which specific levels within the factor are responsible for the significant result.
3. Post hoc tests compare the means of each level of the factor to determine which levels are significantly different from each other and which are not.

The table shows the production budgets and worldwide gross revenues of eight 2018 films. Which statement gives the correct value and interpretation of r?
A. As budgets increased, the gross revenue increased; r = 0.38.
B. For every budget increase of $1 billion, gross revenue increased $0.38 billion; r = 0.38.
C. As budgets increased, the gross revenue increased; r = 0.62.
D. For every budget increase of $1 billion, gross revenue increased $0.62 billion; r = 0.62.
The correct option regarding the correlation coefficient of the data-set is given as follows:
C. As budgets increased, the gross revenue increased; r = 0.62.
What is the correlation coefficient and how to obtain it?The correlation coefficient is an index between -1 and 1 that measures the relationship between two variables, as follows:
negative coefficient: inverse relationship.positive coefficient: direct relationship.absolute value greater than 0.6: strong relationship.absolute value less than 0.6: weak relationship.The coefficient is obtained with a correlation coefficient calculator, inserting the points of the data-set into the calculator.
From the table given by the image, the points are given as follows:
(0.3, 2.05), (0.25, 0.39), (0.2, 1.35), (0.2, 1.24), (0.2, 0.63), (0.18, 0.79), (0.18, 0.53), (0.18, 0.35).
Inserting these points into a calculator, the value of the coefficient is given as follows:
r = 0.62.
Meaning that there is a positive relation amount the variables, and option C is correct.
Option D would be correct if 0.62 was the slope of the line of best fit, hence this is not the case.

Answer:
answer is attached.
Step-by-step explanation:
HELP ME PLEASE AND ONLY RIGHT ANSWERS!
The length of a cell phone is 1.4 inches and the width is 3.4 inches. The company making the cell phone wants to make a new version whose length will be 1.54 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answer: 3.74 inches.
Step-by-step explanation: We can use the following to help us solve this proportion:
1.4 / 1.54 = 3.4 / x (where x is the unknown value that we are trying to solve)
1.54 / 1.4 = 1.1
x / 3.4 = 1.1
The only number that can make the following above true is 3.74, so that is your answer.
Let me know if this is right! :)
