Answers
The (D) mode is the appropriate measure of central tendency for a nominal scale, and variation must be assessed by looking at how responses are distributed among the different response categories.
What is the mode?A set of data values' mode is the value that appears the most frequently.
The value of X at which the probability mass function reaches its highest value is known as the mode if X is a discrete random variable.
In other words, it is the value that will be sampled most frequently.
The proper measure of central tendency for a nominal scale is the mode, and variation must be evaluated by examining the distribution of responses among the various response categories.
When every observed value occurs exactly once in a data collection, there is no mode.
Therefore, the (D) mode is the appropriate measure of central tendency for a nominal scale, and variation must be assessed by looking at how responses are distributed among the different response categories.

what is the sample standard deviation of the following numbers? 4, 9, 5, 8, 7
Answers
Therefore, the sample standard deviation of the given numbers 4, 9, 5, 8, 7 is approximately 2.07.
To find the sample standard deviation of a set of numbers, we can use the following steps:
Calculate the mean (average) of the numbers: (4 + 9 + 5 + 8 + 7) / 5 = 33 / 5 = 6.6
Subtract the mean from each number and square the result:
(4 - 6.6)^2 = (-2.6)^2 = 6.76
(9 - 6.6)^2 = (2.4)^2 = 5.76
(5 - 6.6)^2 = (-1.6)^2 = 2.56
(8 - 6.6)^2 = (1.4)^2 = 1.96
(7 - 6.6)^2 = (0.4)^2 = 0.16
Calculate the sum of the squared differences: 6.76 + 5.76 + 2.56 + 1.96 + 0.16 = 17.2
Divide the sum of squared differences by (n - 1), where n is the number of data points: 17.2 / (5 - 1) = 4.3
Take the square root of the result to get the sample standard deviation: √4.3 ≈ 2.07

1440 tons of grain where brought to a silo over two days. On the second day 80 percent of the amount of the amount of the grain delivered during the first day where brought in. How many tons where delivered on the first day
Answers
Answer:
1152 tons of grains
Step-by-step explanation:
We are told in the above question:
Total number of grains = 1440 tons of grain
On the second day 80 percent of the amount of the amount of the grain delivered during the first day where brought in.
Hence,
The number of grains brought in during the first day = 80% × 1440 tons
= 80/100 × 1440 tons
= 1152 tons of grains

What is a unit?
Units are the instruments used to measure and compare various things. When all measuring units are the same, comparison is simple. Various units can be categorised based on their intended usage. A couple of the units are classed as follows:
The seven SI basic units (The International System of Units (SI), sometimes known as the metric system, is the international measurement standard) are as follows:
Length - meter (m)
Time - second (s)
Amount of substance - mole (mole)
Electric current - ampere (A)
Temperature - kelvin (K)
Luminous intensity - candela (cd)
Mass - kilogram (kg)
Now,
As we have seen in a ruler from any two numbers 1 and 2 or 4 and 5

≤1.8 Work through the simplex method step by step. How the solution changes (i.e., LP has optimal solutions or LP is unbounded or is infeasible)? Why?
Answers
The solution to the linear programming problem 0.3x₁ + 0.1x₂ ≤ 1.8 using the simplex method shows that the problem has optimal solutions.)
Convert the inequality into an equation by subtracting 1.8 from both sides:
0.3x₁ + 0.1x₂ - 1.8 ≤ 0
Introduce slack variables to convert the inequality into an equation:
0.3x₁ + 0.1x₂ + s₁ = 1.8
Set up the initial simplex tableau:
┌───┬───┬───┬───┬───┐
│ │ x₁ │ x₂ │ s₁ │ 1│
├───┼───┼───┼───┼───┤
│ 1│ 0.3│ 0.1│ 1 │1.8│
└───┴───┴───┴───┴───┘
```
Select the pivot column. Choose the column with the most negative coefficient in the bottom row. In this case, it is the second column (x₂).
Select the pivot row. Divide the numbers in the rightmost column (1.8) by the corresponding numbers in the pivot column (0.1) and choose the smallest positive ratio. In this case, the smallest positive ratio is 1.8/0.1 = 18. So the pivot row is the first row.
The simplex method is an iterative procedure that systematically improves the solution to a linear programming problem. It starts with an initial feasible solution and continues to find a better feasible solution until an optimal solution is obtained. In each iteration, the simplex method selects a pivot column and a pivot row to perform row operations, which transform the current tableau into a new tableau with improved objective function values. The process continues until the objective function values cannot be further improved or the linear programming problem is unbounded.

Andre wants to solve the equation 5x^2-4x-18=20. He uses a graphing calculator to graph 5x^2-4x-18 and y=20 and finds that the graphs cross at the points (-2.39,20) and (3.19,20).
a. Substitute the x-value of (-2.39,20) into the expression 5x^2-4x-18. Then evaluate the expression.
Round your answer to the nearest ten thousandth.
Answers
To find the solution to the equation 5x^2-4x-18=20 using the given information, we need to substitute the x-value of (-2.39,20) into the expression 5x^2-4x-18 and evaluate it.
We know that the point (-2.39,20) lies on the graph of the equation 5x^2-4x-18=20. This means that when we substitute x=-2.39 into the equation, we should get a value of 20.
Substituting x=-2.39 into the expression 5x^2-4x-18, we get:
5(-2.39)^2 - 4(-2.39) - 18
Simplifying this expression, we get:
5(5.7121) + 9.56 - 18
= 28.5605 - 8.44
= 20.1205
So, when x=-2.39, the expression 5x^2-4x-18 evaluates to 20.
We were asked to round our answer to the nearest ten thousandth. The value we obtained for 5x^2-4x-18 when x=-2.39 is 20.1205. Rounding this to the nearest ten thousandth gives: 20.1205 rounded to the nearest ten thousandth = 20.1205 (since the digit in the fifth decimal place is less than 5)

If the number B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 from 1985 to 2007 where t = 0 correspond to year 1985
In order to determine the amount of federally insured banks that were there in 1990, we will first calculate the year range from initial time 1985 till 1990
The amount of time during this period is 5years. Substituting t = 5 into the modeled equation will give;
B ( t ) = − 329.4 t + 13747
B(5) = -329.4(5) + 13747
B(5) = -1647+13747
B(5) = 12100
This shows that there will be 12100 federally insured banks are there in the year 1990.

If the quadratic formula is used to find

Answers
The two roots obtained for the quadratic equation by quadratic formula are 1.5 and 4.
What is defined as the quadratic formula?A quadratic equation is just a polynomial with a second degree first term. There are several methods for determining the roots, or solutions, of such a quadratic equation. Every quadratic equation has two solutions, that might or might not be real numbers. The quadratic formula is a simple method for resolving a quadratic equation. whether the answer is a whole number, an irrational number, or perhaps an imaginary numberIf the quadratic equation is ax² + bx + c = 0.
Then, the roots are given by x = [-b ± √(b² - 4ac)]/2a.
The quadratic equation is given as; 2x² - 5x - 12 = 0.
On comparing with the standard form;
a = 2b = -5c = -12Put the values in the formula,
x = [-b ± √(b² - 4ac)]/2a.
x = [-(-5) ± √((-5)² - 4×2×(-12))] / 2×2
On simplification,
x = [5 ± 11]/4
There will be two roots of equation,
a; x = [5 + 11]/4
x = 16/4 = 4
b ; x = [5 - 11]/4
x = 6/4 = 1.5
Thus, the two roots obtained for the quadratic equation by quadratic formula are 1.5 and 4.

D-Adjusted R^2
Answers
the criteria used when deciding upon the inclusion of a variable are A - Theory, B - t-statistic, C - Bias, and D - Adjusted R^2.
When deciding upon the inclusion of a variable, the following criteria are commonly used:
A - Theory: Theoretical justification is often considered to include a variable in a model. It involves assessing whether the variable is relevant and aligns with the underlying theory or conceptual framework.
B - t-statistic: The t-statistic is used to determine the statistical significance of a variable. A variable with a significant t-statistic suggests that it has a meaningful relationship with the dependent variable and may be included in the model.
C - Bias: Bias refers to the presence of systematic errors in the estimation of model parameters. It is important to consider the potential bias introduced by including or excluding a variable and assess whether it aligns with the research objectives.
D - Adjusted R^2: Adjusted R^2 is a measure of the goodness of fit of a regression model. It considers the trade-off between the number of variables included and the overall fit of the model. Adjusted R^2 helps in assessing whether the inclusion of a variable improves the model's explanatory power.
