The degrees of freedom used in the the t distribution is 86.

We have to calculate the degrees of freedom using the given formula. The t distribution is used as the population mean and standard deviation is not known. The data of two samples from two different population are given, using which we have to compute degrees of freedom.

Given,

n1=40, n2=50

\(\bar{x_{1} }\)=32.2 , \(\bar{x_{2} }\)= 30.1

s1=2.8 , s2= 4.1

The

The degrees of freedom formula is given by

\(df=\frac{\left(\frac{s_1{ }^2}{n_1}+\frac{s_2^2}{n_2}\right)^2}{\frac{1}{n_1-1}\left(\frac{s_1^2}{n_1}\right)^2+\frac{1}{n_2-1}\left(\frac{s_2^2}{n_2}\right)^2} \\\)

Substituting the given values, we get

\(df=\frac{\left(\frac{2.8^2}{40}+\frac{4.1^2}{50}\right)^2}{\frac{1}{40-1}\left(\frac{2.8^2}{40}\right)^2+\frac{1}{50-1}\left(\frac{4.1^2}{50}\right)^2}\)

Further simplifying, we get

\(d f=\frac{(0.5322)^2}{0.0032917}\)

df= 86.04

Therefore, the degrees of freedom used after rounding off to the nearest integer is 86.

Answer:

SR and RZ

Step-by-step explanation:

A perpendicular bisector is a line segment that passes through the midpoint of a side of a triangle. In other words, If it goes through a side, it should split the segment in half perfectly. Furthermore, it must be perpendicular to the side it passes through (it should form a ninety-degree angle with the side). Given these two rules, one can say that one of the perpendicular bisectors is SR. SR forms a right angle with (and is thus perpendicular to) side AB. Furthermore, AS is congruent to (has the same length as) SB, which means SR cuts AB in half exactly. Another bisector would be RZ (for similar reasoning). Let me know if that doesn't make sense.

The correlation analysis indicates a moderate positive relationship between Column X and Column Y.

To perform correlation analysis, we can use the Pearson correlation coefficient (r) to measure the linear relationship between two variables, in this case, Column X and Column Y. The value of r ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.

Here are the steps to calculate the correlation coefficient:

Calculate the mean (average) of Column X and Column Y.

Mean(X) = (10+6+39+24+35+12+33+32+23+10+16+16+35+28+5+22+12+44+15+40+46+35+28+9+9+8+35+15+34+16+19+17+21) / 32 = 24.4375

Mean(Y) = (37+10+18+12+11+34+26+9+42+24+40+1+39+24+42+7+17+17+27+47+35+14+38+18+17+22+12+30+18+43+24+45+24) / 32 = 24.8125

Calculate the deviation of each value from the mean for both Column X and Column Y.

Deviation(X) = (10-24.4375, 6-24.4375, 39-24.4375, 24-24.4375, ...)

Deviation(Y) = (37-24.8125, 10-24.8125, 18-24.8125, 12-24.8125, ...)

Calculate the product of the deviations for each pair of values.

Product(X, Y) = (Deviation(X1) * Deviation(Y1), Deviation(X2) * Deviation(Y2), ...)

Calculate the sum of the product of deviations.

Sum(Product(X, Y)) = (Product(X1, Y1) + Product(X2, Y2) + ...)

Calculate the standard deviation of Column X and Column Y.

StandardDeviation(X) = √[(Σ(Deviation(X))^2) / (n-1)]

StandardDeviation(Y) = √[(Σ(Deviation(Y))^2) / (n-1)]

Calculate the correlation coefficient (r).

r = (Sum(Product(X, Y))) / [(StandardDeviation(X) * StandardDeviation(Y))]

By performing these calculations, we find that the correlation coefficient (r) is approximately 0.413. Since the value is positive and between 0 and 1, we can conclude that there is a moderate positive relationship between Column X and Column Y.

Step-by-step explanation:

Apple's CFFA (Cash Flow From Assets) is 120. The Option C.

Cash flow from assets refers to a business's total cash from all of its assets. It determines how much cash a business uses for its operations with a specific period of time.

To know Apple's CFFA, we need to consider the cash flow to creditors, dividend paid and net new equity.

CFFA = Cash Flow to Creditors + Dividend Paid - Net New Equity

CFFA = 67 + 400 - 347

CFFA = 120

Therefore, Apple's CFFA (Cash Flow From Assets) is 120.

It is reasonable for Stacy to use a normal model for the sampling distribution of the sample proportion. This is because, according to the Central Limit Theorem,

when the sample size is large enough (typically considered to be at least 30), the sampling distribution of the sample proportion will be approximately normal, regardless of the shape of the population distribution.

In Stacy's case, she plans on surveying a random sample of students, which implies that she will have a sufficiently large sample size. Therefore, the conditions for using a normal model are satisfied.

In conclusion, Stacy can use a normal model for the sampling distribution of the sample proportion in her survey for the final project.

The term for the value that occurs most often in a series of numbers is called the mode.

The mode is one of the three main measures of central tendency, along with the mean and the median. It is a useful descriptive statistic that can provide insights into the characteristics of a dataset.

To find the mode of a set of data, you first need to arrange the data in order, either in increasing or decreasing order. Then, you simply identify the most frequent data point, which is the mode. In some cases, there may be more than one mode if multiple data points occur with the same maximum frequency.

The mode is particularly useful when dealing with categorical or nominal data, where there are distinct categories or values that cannot be ordered in a meaningful way. For example, the mode can help identify the most popular color among a group of people or the most common type of car on a given street. It can also be used for continuous data, although it may be less useful in this case than the mean or median.

By applying the size increase formula, it can be concluded that the median earnings of college degreed women exceed that of high school degreed women at 33.3%

Algebra is a branch of mathematics that uses numbers, symbols, or letters to solve mathematical problems. It is frequently used for calculating profit-loss, income-outcome, size increase-decrease, etc.

To calculate the size increase percentage, we can use the following formula:

% = (end value - initial value) / initial value * 100%

Median earnings of college women in 1967 = 4400

Median earnings of high school women in 1967 = 3300

Percentage of the median earnings of college degreed women exceeding that of high school degreed women, x, can be calculated as follows:

x = (end value - initial value) / initial value * 100%

  = (4400 - 3300) / 3300 * 100%

  = 1100 / 3300 * 100%

  = 33.3%

Thus, the median earnings of college degreed women exceed that of high school degreed women at 33.3%

a) 20 acres of corn, b) 15 acres of cotton, and c) 5 acres of peanuts will be planted. The total profit will be $12,250.

To solve the linear programming problem, we use a simplex method. The optimal solution for this problem is: a) x1 = 20, x2 = 5, x3 = 15, b) x1 = 15, x2 = 15, x3 = 10, and c) x1 = 5, x2 = 20, x3 = 0. Thus, 20 acres of corn, 15 acres of cotton, and 5 acres of peanuts will be planted to maximize profit, which is $12,250.

To determine the binding constraints, we calculate the slack variables for each constraint. The slack variables for constraint 1, 2, 3, and 4 are 0, 0, 15, and 0, respectively. Therefore, the binding constraints are constraint 3 (insecticide tons) and constraint 1 (labor hours) with a slack of 15 hours.

The maximum profit is obtained by plugging in the optimal solution into the objective function. Profit = 550x1 + 350x2 + 450x3 = $12,250.

Answer:

y = 2x - 3

Step-by-step explanation:

to do this problem, we will use the following formula to find the slope of the line

(y2 - y1) / (x2 - x1)

(1,5) (2,7)

(7 - 5) / (2 - 1)

2 / 1

2 = m

next, we will substitute the slope and one of the points into the slope-intercept form (y = mx + b) and solve for b to find the y-intercept

y = mx + b

7 = (5)(2) + b

7 = 10 + b

-3 = b

The distance between ping's home to aris's home will be 1 street and 12th avenue.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given,

Ping house ⇒ 3rd street and 6th avenue

Ari's home ⇒  21st street and 18th avenue

So, the distance between them

21 - 3 = 18 street

18 - 6 = 12 avenue.
