Describe Triangle?A triangle is a polygon with three sides and three angles. It is one of the basic shapes in geometry and is widely used in mathematics, science, engineering, and many other fields. Triangles are important because they have simple properties that can be used to solve more complex problems.
There are several ways to classify triangles based on their properties. One way is to classify them by their sides. A triangle can be classified as equilateral, isosceles, or scalene depending on whether all three sides are equal, only two sides are equal, or all three sides are different, respectively.
Another way to classify triangles is by their angles. A triangle can be classified as acute, right, or obtuse depending on whether all three angles are less than 90 degrees, one angle is exactly 90 degrees, or one angle is greater than 90 degrees, respectively.
In a right angled triangle, the side opposite the 45-degree angle is equal to the other two sides divided by the square root of 2. Therefore, we have:
a = b/√(2)
c = 5√(6)
We can use the Pythagorean theorem to relate the sides a, b, and c:
a² + b² = c²
Substituting the values we have:
(b/√(2))² + b² = (5√(6))²
Simplifying:
b²/2 + b² = 150
3b²/2 = 150
b² = 100
b = √(100) = 10
Therefore, the exact value of b is A. 10.

Clayton's Burgers cooks its burgers either well done or medium. Last night the restaurant served 10 burgers in all, 1 of which was well done. What percentage of the burgers were well done?
Write your answer using a percent sign (%).
Answers
Answer:
10%
Step-by-step explanation:
To find the percentage of well-done burgers, we need to divide the number of well-done burgers by the total number of burgers and then multiply by 100%. In this case, we have 1 well-done burger and 10 total burgers, so the percentage of well-done burgers is 1/10 * 100%, or 10%. Therefore, the answer is 10%.

you will thoroughly analyze a set of data. First you are to describe the data so that the reader can
place it in context, then do each of the following. Your analysis will include all the items mentioned
below, making sure you explain yourself at each step. Graphs, calculations, and numbers without
comment are not allowed. Put this all nicely together as one item, ordering items close to how they are
given below.
Use the data set on the other side of the page. Make a histogram and analyze it using terms learned in
class. Present a 5 number summary and modified box plot. Are there any outliers? Report the mean
and standard deviation. (DO NOT discard outliers) The mean was important in this experiment.
Calculate a 95% confidence interval for the true mean. Explain what this means. Compare these (5
number summary and mean/standard deviation). Are the mean and standard deviation valid for this
set of data? Justify your answer. Some of the above (and what follows below) makes no sense if the
data is not approximately normal. Explain what this means. Is this data close to normally distributed?
Justify your answer. Regardless of your conclusion, for the next part assume the data is approximately
normal. \
The data is listed in the order it was recorded (down first, then across). Do a time plot. Analyze this plot,
paying special attention to new information gained beyond what we did above. Cut the data in half
(first three columns vs. last three columns) and do a back to back stem plot. Analyze this. Does this
further amplify what the time plot showed? Calculate the mean of the second half of the data. Using
the mean and standard deviation of the whole data set (found above) as the population mean and
standard deviation, test the significance that the mean of the second half is different than the mean of
the total using a = 0.05. Make sure to clearly identify the null and alternative hypothesis. Explain what
this test is attempting to show. Report the p-value for the test and explain what that means. Accept or

Answers
1. Describing the data:
- The data set is listed in a specific order, with the values recorded vertically and then horizontally.
- It is important to note that the context or nature of the data is not specified.
2. Creating a histogram:
- We will construct a histogram using the data set.
- The histogram will provide a visual representation of the distribution of the data.
3. Analyzing the histogram:
- We will use terms learned in class to analyze the histogram, such as shape (symmetrical, skewed, etc.), central tendency, and spread.
- This analysis will help us understand the characteristics of the data distribution.
4. Presenting a 5-number summary and modified box plot:
- We will calculate the five-number summary (minimum, first quartile, median, third quartile, maximum) for the data set.
- Using this summary, we will construct a modified box plot to visualize the distribution and identify any potential outliers.
5. Identifying outliers:
- We will examine the modified box plot to identify any outliers in the data set.
- Outliers are values that significantly deviate from the rest of the data and may have an impact on the mean and standard deviation.
6. Calculating the mean and standard deviation:
- We will calculate the mean and standard deviation for the entire data set.
- The mean represents the average value of the data, while the standard deviation measures the spread or variability around the mean.
7. Interpreting the 95% confidence interval for the true mean:
- We will calculate a 95% confidence interval for the true mean of the data.
- This interval will provide a range within which we are 95% confident that the true population mean lies.
8. Comparing the 5-number summary and mean/standard deviation:
- We will compare the characteristics of the data set provided by the 5-number summary and the mean/standard deviation.
- This will help us determine if the mean and standard deviation are valid measures for this particular data set.
9. Assessing normality of the data:
- We will discuss the concept of data being approximately normal and its implications.
- We will examine the histogram and other visualizations to determine if the data appears to follow a normal distribution.
10. Time plot analysis:
- We will create a time plot using the data set, considering the order in which the data was recorded.
- The time plot will allow us to observe any trends or patterns in the data over time.
11. Analyzing the time plot:
- We will analyze the time plot, paying attention to any new information gained beyond the previous steps.
- This analysis will help us understand any temporal patterns or changes in the data.
12. Conducting a back-to-back stem plot:
- We will divide the data into two halves: the first three columns and the last three columns.
- Using a back-to-back stem plot, we will compare the distributions of the two halves and identify any differences.
13. Mean of the second half of the data:
- We will calculate the mean of the second half of the data set.
- This will help us compare the mean of the second half to the overall mean of the entire data set.
14. Testing the significance of the mean of the second half:
- Using the mean and standard deviation of the entire data set as the population parameters, we will conduct a hypothesis test.
- The null hypothesis will state that the mean of the second half is equal to the mean of the total, while the alternative hypothesis will suggest they are different.

Answers
A plot is provided showing the interest rate on a 3-month bond from 1950 to 1980, along with a regression model fit to the relationship between the interest rate (in %) and the years since 1950. The task is to complete parts (a) through (d) based on the plot and regression model.
(a) From the plot and regression model, we can observe the trend in the interest rate on a 3-month bond over the given time period. By analyzing the plot and regression line, we can make predictions and draw conclusions about the relationship between the interest rate and the years since 1950.
(b) The regression model provides an equation that represents the relationship between the interest rate and the years since 1950. By examining the equation and the coefficients, we can gain insights into the impact of time on the interest rate.
(c) Using the regression model, we can estimate the interest rate on the 3-month bond for specific years since 1950 that fall within the observed time period. By plugging in the values of years since 1950 into the regression equation, we can obtain predicted interest rates.
(d) Based on the regression model and the observed data, we can assess the goodness of fit of the model. This involves evaluating statistical measures such as the coefficient of determination (R-squared) to determine how well the regression model captures the variation in the interest rate data.

Write an equation to represent this situation. Let n be the number of years before the class will have 100 students.
(Type an equation using n as the vanable. Use integers or decimals for any numbers in the equation)
Help again please
Answers
Therefore, in about 15 years and 2 months, the senior class will have about 100 students.
What is equation?An equation is a statement that expresses the equality of two mathematical expressions using mathematical symbols such as variables, numbers, and mathematical operations. The equality is represented by an equal sign "=" between the two expressions. Equations are used to represent mathematical relationships and solve problems in various fields such as physics, chemistry, engineering, and economics.
Given by the question.
Let P be the initial population of the senior class in the high school, and r be the rate of decrease in population per year (in decimal form).
Then, we can write the following equation to represent the situation:
P\((1-r)^{n}\) = 100
We know that the current population of the senior class is 320, so we can substitute these values into the equation:
320\((1-0.07)^{n}\) = 100
Simplifying the equation, we get:
\(0.93^{n}\) = 0.3125
Taking the natural logarithm of both sides, we get:
n ln (0.93) = ln (0.3125)
Dividing both sides by ln (0.93), we get:
n = ln (0.3125) / ln (0.93)
Using a calculator, we find that n is approximately equal to 15.21 years.

a first order reaction goes to half completion in 79 hours. what is the rate constant for this reaction? a) 7.9 × 10–3 h–1 b) 8.77 × 10–3 h–1 c) 79 h d) 39.5 h
Answers
The rate of constant for the above-given first-order reaction is b.) 8.77 × 10–3 h–1.
The half-life of a first-order reaction can be calculated using the equation t1/2 = ln(2)/k, where t1/2 is the half-life and k is the rate constant.
In this case, we know that the reaction goes to half completion in 79 hours. Therefore, the half-life is also 79 hours.
Plugging this into the equation, we get:
79 = ln(2)/k
Solving for k, we get:
k = ln(2)/79
Using a calculator, we can evaluate this expression to get:
k = 8.77 × 10–3 h–1
Therefore, the correct answer is b) 8.77 × 10–3 h–1.

b. The area between −z and z is 0.9830. z =
c. The area between −z and z is 0.2148. z =
d. The area to the left of z is 0.9997. z =
e. The area to the right of z is 0.6847. z=
Answers
The z-values for the given situations are approximate:
a. The area to the left of z is 0.1827. z = -0.90
b. The area between −z and z is 0.9830. z = 2.17
c. The area between −z and z is 0.2148. z = 0.85
d. The area to the left of z is 0.9997. z = 3.49
e. The area to the right of z is 0.6847. z= -0.48
a. For an area of 0.1827 to the left of z, the corresponding z-value can be found using a standard normal distribution table or a statistical calculator. The z-value is approximately -0.90.
b. To find the z-value for an area between -z and z equal to 0.9830, we need to find the value that corresponds to (1 - 0.9830)/2 = 0.0085 in the upper tail of the standard normal distribution. Using the table or calculator, the z-value is approximately 2.17.
c. Similarly, for an area between -z and z equal to 0.2148, we find the value that corresponds to (1 - 0.2148)/2 = 0.3926 in the upper tail. The z-value is approximately 0.85.
d. For an area of 0.9997 to the left of z, we find the value that corresponds to 0.9997 in the upper tail. The z-value is approximately 3.49.
e. To find the z-value for an area to the right of z equal to 0.6847, we find the value that corresponds to 1 - 0.6847 = 0.3153 in the upper tail. The z-value is approximately -0.48.
In summary, the z-values for the given situations are approximate:
a. -0.90
b. 2.17
c. 0.85
d. 3.49
e. -0.48
These values can be used to determine the corresponding percentiles or probabilities for the standard normal distribution. The values are typically found using standard normal distribution tables or statistical calculators that provide the cumulative probability distribution function (CDF) for the standard normal distribution.
