In right triangle ABC, m∠B ≠ m∠C. Let sin B = r and cos B = s. What is sin C – cos C?
==================================================
Explanation:
We'll need these trig ratios
sine = opposite/hypotenusecosine = adjacent/hypotenuseRefer to the diagram below.
sin(B) = r = r/1 which tells us that the side opposite angle B is r units long. The hypotenuse is 1.
cos(B) = s = s/1 means the adjacent side to angle B is of length s
sides r and s are the two legs of the right triangle.
----------
From that diagram, we can then say:
sin(angle) = opposite/hypotenuse
sin(C) = s/1
sin(C) = s
This is identical to cos(B). We can say cos(B) = sin(C)
Also, we can say:
cos(angle) = adjacent/hypotenuse
cos(C) = r/1
cos(C) = r
So cos(C) = sin(B)
This works because B+C = 90
----------
So,
sin(C) - cos(C) = cos(B) - sin(B) = s - r
Use f(x)=|x| f(x) is shifted down 4 and right 3 to create h(x) Which answer shows the correct function for h(x) ? h(x)=|x-3|+4 b
The correct function for h(x), which represents the transformation of f(x) by shifting it down 4 units and right 3 units, is h(x) = |x - 3| + 4. To determine the correct function for h(x) that represents the desired transformation of f(x).
We need to understand the effects of shifting down and right on the absolute value function. Shifting a function down by a certain number moves all the points on the graph vertically downward by that amount. In this case, f(x) is shifted down by 4 units. To achieve this, we add 4 to the original function, resulting in |x| + 4.
Shifting a function right by a certain number moves all the points on the graph horizontally to the right by that amount. In this case, f(x) is shifted right by 3 units. To achieve this, we replace x in the function with (x - 3), resulting in |x - 3|.Combining the two transformations, we have h(x) = |x - 3| + 4, which correctly represents the function obtained by shifting f(x) down 4 units and right 3 units.
In h(x) = |x - 3| + 4, the term |x - 3| represents the absolute value of the shifted variable x - 3, and adding 4 moves the entire graph vertically upward by 4 units. Therefore, h(x) = |x - 3| + 4 is the correct function for h(x), representing the desired transformation of f(x) by shifting it down 4 units and the right 3 units.

a team has twelve 15-year-old players and eight 16-year-old players. the coach of the team is 43 years old. which measure of central tendency best represents the ages of the team, including the coach, and why?
The best measure of central tendency to represent the ages of the team, including the coach, would be the mean or average age.
To calculate the mean, we add up all the ages and divide by the total number of people:
Mean = (Sum of all ages) / (Total number of people)
In this case, we have:
12 players who are 15 years old
8 players who are 16 years old
1 coach who is 43 years old
So, the total number of people is 12 + 8 + 1 = 21.
The sum of all the ages is:
12 × 15 (years old) + 8 × 16 (years old) + 43 (years old) = 180 + 128 + 43 = 351 (years old)
Therefore, the mean age of the team is:
Mean = 351 / 21 = 16.71 (rounded to two decimal places)
The mean is a good measure of central tendency because it takes into account all the ages in the team, including the coach, and provides an average value that is representative of the ages of the entire team. It is also a useful measure for making comparisons between different groups or teams based on their age and to estimate the mean ages of various people.

he expected to have 15 customers each day. to answer whether the number of customers follows a uniform distribution, a chi-square test for goodness of fit should be performed. (alpha
To determine whether the number of customers, which is expected to be 15 each day, follows a uniform distribution, a chi-square test for goodness of fit should be performed with a specified significance level (alpha).
The chi-square test for goodness of fit is used to determine if observed data follows an expected distribution. In this case, we want to test whether the number of customers each day, which is expected to be 15, follows a uniform distribution.
To perform the test, we need to collect data on the number of customers over a period of time and compare it to the expected uniform distribution. The observed frequencies for each category (e.g., the number of days with 0 customers, 1 customer, 2 customers, etc.) would be obtained.
Then, the chi-square test statistic can be calculated based on the observed and expected frequencies. The test statistic measures the discrepancy between the observed and expected distributions.
To interpret the test results, we compare the calculated chi-square value to the critical chi-square value at the chosen significance level (alpha). If the calculated chi-square value exceeds the critical value, we reject the null hypothesis and conclude that the number of customers does not follow a uniform distribution. Conversely, if the calculated chi-square value does not exceed the critical value, we fail to reject the null hypothesis, indicating that the number of customers can be considered to follow a uniform distribution.
Please note that the specific calculations and decision-making process require additional data and the use of statistical software or tables to obtain the critical chi-square value.

A: Balance a ration for 70% TDN (DM) using bromegrass hay and wheat middlings. What percent of bromegrass hay is in the ration? (number only) B: Wet beet pulp contains 17% DM and 13.60 Mcal NEm/cwt, on an as fed basis. What is the concentration of NEm (Mcal/cwt) on a DM basis?
A: The percent of bromegrass hay in the ration is 30%.
B: The concentration of NEm on a DM basis is 16.00 Mcal/cwt.
To balance a ration for 70% TDN (DM) using bromegrass hay and wheat middlings, we need to determine the percentage of bromegrass hay in the ration. Since the total ration needs to provide 70% TDN, the remaining portion (30%) will be composed of wheat middlings. Therefore, the percent of bromegrass hay in the ration is 30%.
Wet beet pulp contains 17% DM and 13.60 Mcal NEm/cwt on an as-fed basis. To find the concentration of NEm on a DM basis, we need to convert the values to a dry matter basis. Since wet beet pulp has 17% DM, it means that 83% of it is moisture.
The NEm value of 13.60 Mcal/cwt is already on an as-fed basis, considering the total weight including moisture. To find the NEm concentration on a DM basis, we divide the NEm value by the percentage of DM, which is 17%. So, the concentration of NEm on a DM basis is 13.60 Mcal/cwt / 0.17 = 16.00 Mcal/cwt.
By calculating these values, we can determine the percentage of bromegrass hay in the ration and the concentration of NEm on a DM basis.

OLAP is used for the analysis of accumulated data, and it requires a data warehouse.
while OLTP is used for transaction processing and requires a database optimized for real-time transaction processing. The analysis of accumulated data is known as Online Analytical Processing (OLAP), and it involves a data warehouse. OLAP is a business intelligence tool used for multi-dimensional analysis of large data sets, while a data warehouse is a central repository that stores historical and current data from multiple sources in a structured manner. OLAP allows users to perform complex queries on large data sets, analyze trends, and make informed business decisions. It is often used in data mining and decision support systems. OLAP tools can be used to slice and dice data, drill down to more detailed data, and roll up to higher levels of summary data. OLAP is primarily used for analytical purposes and is not designed for transaction processing. On the other hand, a data warehouse is designed to support OLAP and is used for storing large amounts of historical data that can be queried and analyzed. Data is extracted from various sources, transformed, and loaded into the data warehouse in a structured format, enabling efficient querying and analysis. OLTP (Online Transaction Processing), on the other hand, is a type of transaction processing that is designed for processing real-time transactions in databases. It is used for day-to-day operations such as order processing, inventory management, and customer management. OLTP is optimized for processing large volumes of transactions in real-time, and is not suitable for analytical purposes.
In summary, OLAP is used for the analysis of accumulated data, and it requires a data warehouse, while OLTP is used for transaction processing and requires a database optimized for real-time transaction processing.

Tim’s mom filled the gas tank in her SUV and spent $72.00 for 22.5 gallons of unleaded gasoline. What is the constant of proportionality that relates the cost in dollars, y, to the number gallons of unleaded gasoline, x?
The constant of proportionality that relates the cost in 72 dollars as y, to the number of gallons of unleaded gasoline in 22.5 gallons of unleaded gasoline as x is $3.20 per gallon of unleaded gasoline.
The constant of proportionality is the ratio of the so-called proportional relationship that relates two given values to each other.
Other names for the constant of proportionality are constant ratio, constant rate, unit rate, variable constant, and even rate of change.
The relationship between two variables, X and Y, is directly proportional if it can be expressed in terms of Y/X = k or Y = Xk.
y/x = k
k is the constant of proportionality.
Given that:
y = $72 and x = 22.5 gallons.
So, the value of the constant of proportionality (k) = 72/22.5
=> k = 720/225
Dividing both by the numerator and denominator by 45. We get,
=> k = 16/5
The value of the constant of proportionality (k) = $3.20 per gallon of unleaded gasoline.

The correct answer is c. P(B∣A) = b/a.
When two events A and B are independent, it means that the occurrence of one event does not affect the probability of the other event. In this case, P(B∣A), the probability of event B given event A, is equal to the probability of event B, which is b.
P(A∣B), the probability of event A given event B, would be calculated using Bayes' theorem:
P(A∣B) = P(A) * P(B∣A) / P(B)
Since P(B∣A) = b/a and P(B) = b, substituting these values into Bayes' theorem, we get:
P(A∣B) = a * (b/a) / b = 1
Therefore, P(A∣B) is equal to 1.

Lines AB and CD intersect at E. If the measure of angle AEC=5x-20 and the measure of angle BED=x+50, find, in degrees, the measure of angle CEB.
Answer: 112.5
Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

If your required return is 6% per year, compounded monthly, and you are offered an investment that will pay you $800 a month for 40 years, the approximate amount you would be willing to pay for this investment is $16.80.
To determine the present value of the investment, we need to calculate the discounted value of the future cash flows. In this case, the cash flow is $800 per month, and the time period is 40 years, or 480 months.
Using the formula for present value, which is \(PV = CF / (1 + r)^n\), where PV is the present value, CF is the cash flow, r is the required return per period, and n is the number of periods, we can substitute the given values:
PV = $800 / (1 + 0.06/12)\(^(480)\)
Simplifying the expression, we find that the present value is approximately $16.80. This means that if you want to achieve a required return of 6% per year, compounded monthly, you would be willing to pay approximately $16.80 for this investment.
