Party Rental rents tables for $8 per table
plus a $20 delivery fee. How many tables
do you have to rent to have the cost of the
rental be the same. Write and solve an
equation.
Answers
The equations are H = 4x + 60 and P = 8x + 20. We need to rent 10 tables to ensure that the cost of the rental will be the same.
What is system of equations?A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."
Let us suppose tables as x.
Given that,
The happy party rents tables for $4 per table plus a delivery fee of 60. This is expressed as:
H = 4x + 60
Party Rental rents tables for $8 per table plus a $20 delivery fee.
P = 8x + 20
To get the same cost of the rent:
H = P
4x + 60 = 8x + 20
60 - 20 = 8x - 4x
40 = 4x
x = 10
Hence, we need to rent 10 tables to ensure that the cost of the rental will be the same.

Each pair of numbers (m, h) which meet the inequality is the answer to the inequality. m < h plus 2.
Pairs of numbers: what are they?A factor pair is a collection of two factors that, when multiplied together, produce a certain result in mathematics. In those other words, it's a pair of integers that we multiply to produce a result. For instance, the factor pair that yields the result in the multiplication formula 6 7 = 42 is composed of the numbers 6 and 7. 42
By adding 14 to both sides, starting with -14 + 7m 7h, we may simplify the left side:
-14 + 7m plus 14 < 7h plus 14
Even more condensed, we get at:
7m < 7h plus 14
The inequality can then be divided by 7 on both sides: m h + 2.

What is the probability of 3 people sharing the same birthdays? How many different pairs of people are there when there are three humans? (Think nPr or nCr)
Answers
The probability of three people sharing the same birthdays is approximately \(0.0000075\) or \(0.00075\)%, and there are three different pairs of people when there are three humans.
The probability of three people sharing the same birthday depends on the assumptions made about the distribution of birthdays. Assuming that birthdays are uniformly distributed throughout the year and that leap years are not considered, there are \(365\) possible birthdays for each person. The first person can have any birthday, and the probability that the second person shares the same birthday is \($\frac{1}{365}$\). Similarly, the probability that the third person shares the same birthday as the first two is also \($\frac{1}{365}$\). Multiplying these probabilities together, we get \($\left(\frac{1}{365}\right) \times \left(\frac{1}{365}\right) = \frac{1}{133,225}$\), approximately \(0.0000075\) or \(0.00075\%\).When there are three humans, the number of different pairs of people can be calculated using the combination formula, also known as \($\binom{n}{r}$\). In this case, \($n$\) represents the total number of people (\(3\)), and \($r$\) represents the number of people chosen at a time (\(2\) for pairs). Applying the formula, we have \($\binom{3}{2} = 3$\). Therefore, there are three different pairs of people when there are three humans: (\(1,2\)), (\(1,3\)), and (\(2,3\)).In conclusion, the probability of three people sharing the same birthdays is extremely low (approximately \(0.0000075 \ or \ 0.00075\%\)), and when there are three humans, there exist three different pairs of people.

1- Show that Au is the projection of u on the x axis.
2- modify the matrix A to obtain a matrix B so that Bu is theprojection of u on the u axis. A= [1 0; 0 0] u[a;b]
Answers
1. To show that Au is the projection of u on the x-axis, first note that Au is the dot product of A and u: Au = [a 0; 0 0]. Since A is a 2x2 matrix, the dot product is simply the multiplication of the elements in the first row of A by the elements in u. In this case, the first row of A contains a single non-zero element, 1, and the product of 1 and a is a, which is the x-coordinate of u. Thus, Au is equal to the projection of u on the x-axis.
2. To modify the matrix A to obtain a matrix B such that Bu is the projection of u on the y-axis, we must add an additional non-zero element to the second row of A. In particular, if we add b to the second row of A, we get the matrix B = [1 0; 0 b]. Thus, Bu = [a b; 0 0]. Since the second row of B contains a non-zero element, b, the product of b and b is b, which is the y-coordinate of u. Thus, Bu is equal to the projection of u on the y-axis.

Composite functions are functions derived from combining other functions
The values of the composite functions are \((f + g)(2) = -3\) and \((f - g)(2) = 41\)
How to determine the composite functionsThe single functions are given as:
\(f(x) =11 + 2x^2\)
\(g(x) = -7x - 3x^2 + 4\)
To calculate (f + g)(x), we make use of
\((f + g)(x) = f(x) + g(x)\)
So, we have:
\((f + g)(x) = 11 + 2x^2 - 7x - 3x^2 + 4\)
Collect the like terms
\((f + g)(x) = 2x^2- 3x^2 - 7x + 4+11\)
Evaluate
\((f + g)(x) = - x^2 - 7x + 15\)
Substitute 2 for x
\((f + g)(2) = - 2^2 - 7(2) + 15\)
\((f + g)(2) = -3\)
To calculate (f - g)(x), we make use of
\((f + g)(x) = f(x) - g(x)\)
So, we have:
\((f - g)(x) = 11 + 2x^2 + 7x + 3x^2 - 4\)
Collect the like terms
\((f - g)(x) = 2x^2 + 3x^2+ 7x - 4 + 11\)
Evaluate
\((f - g)(x) = 5x^2+ 7x +7\)
Substitute 2 for x
\((f - g)(2) = 5 * 2^2+ 7* 2 +7\)
\((f - g)(2) = 41\)
Hence, the values of the composite functions are \((f + g)(2) = -3\) and \((f - g)(2) = 41\)

Sum and differences of functionGiven the following function expressed as:
f(x) = 11x + 2x^2 and;
g (x) = -7x - 3x^2 + 4
Taking the sum of the function
f(x) + g(x) = 11x + 2x^2 -7x - 3x^2 + 4
f(x) + g(x) = -x^2 + 4x + 4
If x = 2,
f(x) + g(x) = -4 + 8 + 4
f(x) + g(x) = 0
For the difference;
f(x) - g(x) = 11x + 2x^2 + 7x + 3x^2 - 4
f(x) - g(x) = 5x^2 + 18x - 4
If x = 2,
f(x) - g(x) = 5(4) + 36 - 4
f(x) - g(x) = 52

a positively skewed distribution is due to: an extremely small number. an extremely large number. the fact that all data is equal. none of these choices are correct.
Answers
A positively skewed distribution is due to an extremely large number.
What is positively skewed distribution?A positively skewed distribution is a type of distribution in which the majority of the data values are clustered towards the left side of the distribution, with a tail extending to the right. This means that there are relatively more smaller values in the dataset than larger values. In a positively skewed distribution, the mean of the dataset is typically larger than the median, and the mode may not be a good representation of the central tendency of the data. This is because the presence of a long tail on the right-hand side of the distribution pulls the mean towards the higher values, while the median remains closer to the center of the dataset. Some common examples of positively skewed distributions include income distributions, where there are a few extremely high earners that skew the data towards the right, and test scores, where there may be a few students who perform extremely well and pull the average higher than the median.
Here,
A positively skewed distribution occurs when the tail of the distribution extends to the right, and the majority of the data is clustered towards the left side of the graph. This means that there are relatively more smaller values in the dataset than larger values. One common cause of positive skewness is the presence of extremely large values, also called outliers, in the dataset. These large values pull the mean of the dataset towards the right, resulting in the tail of the distribution stretching in that direction.
Therefore, out of the options provided, the correct answer is "an extremely large number."

what standard deviation is used in scientific?
Answers
The standard deviation used in scientific research is typically the sample standard deviation, also known as the population standard deviation estimator. It is a measure of the dispersion or variability of data points around the mean.
In scientific research, the standard deviation is a commonly used statistical measure that quantifies the spread of data points in a sample or population. It provides information about how much individual data points deviate from the mean. The sample standard deviation is used when working with a sample of data to estimate the population standard deviation.
The formula for calculating the sample standard deviation involves taking the square root of the average of the squared differences between each data point and the mean. It is represented by the symbol "s" and is used to describe the variability or dispersion of data within the sample.
The population standard deviation, represented by the symbol "σ," is used when working with an entire population rather than a sample. However, in scientific research, due to practical limitations, researchers often rely on sample data to make inferences about the larger population. Therefore, the sample standard deviation is commonly used as an estimator for the population standard deviation.

TRUE/FALSE. If the value of the Pearson correlation is r = +1.00 or -1.00, then all data points in a scatter plot fit perfection on a straight line.
Answers
False.
While a Pearson correlation coefficient of +1.00 or -1.00 indicates a strong linear relationship between two variables, it does not necessarily mean that all data points will fit perfectly on a straight line. The correlation coefficient measures the strength and direction of the linear relationship, but it does not guarantee that the data points will fall exactly on a straight line.
Scatter plots with a perfect linear relationship will have all data points lying precisely on a straight line, but this is not always the case even when the correlation coefficient is +1.00 or -1.00. There can still be some degree of scatter or variation around the line, depending on other factors such as measurement errors, outliers, or the presence of other nonlinear relationships in the data.
