A 4-column table with 4 rows. The first column has no label with entries C, D, E, total. The second column is labeled A with entries X, Y, Z, 1. 0. The third column is labeled B with entries 0. 25, 0. 68, 0. 07, 01. 0. The fourth column is labeled total with entries G, H, J, 1. 0. Which value for Y in the table would be least likely to indicate an association between the variables? 0. 06 0. 24 0. 69 1. 0.
Answers
The value 1.0 for Y would be the least likely to indicate an association between the variables.
To determine which value for Y in the table would be least likely to indicate an association between the variables, we need to examine the relationship between the variables A, B, and Y. From the given table, we can observe that the values in column A (X, Y, Z) represent different categories or levels of a variable. Similarly, the values in column B (0.25, 0.68, 0.07) represent different levels or measurements of another variable. The variable Y represents the intersection or combination of variables A and B. It shows the joint occurrence or frequency of the different levels of variables A and B. In order to determine the value of Y that would be least likely to indicate an association between the variables, we need to look for a value of Y that deviates significantly from the expected pattern or distribution based on the values in columns A and B. Among the given options, the value 1.0 would be the least likely to indicate an association between the variables. This is because a value of 1.0 for Y suggests a complete overlap or perfect association between variables A and B, which is unlikely if the other values in columns A and B do not exhibit such a strong relationship.
Therefore, the value 1.0 for Y would be the least likely to indicate an association between the variables.

ANSWER ASAP!!! || use the net to find the surface area of the prism Ik the answer is 178.3 but I NEED TO SHOW WORK
Answers
The surface area of the regular pyramid is 178.3 mm² if the area of the base is 43.3 mm².
The surface area of a regular pyramid can be calculated using the following formula
Surface Area = Base Area + (1/2) x Perimeter of Base x Slant Height
Base area = 43.3 mm²
Perimeter of base = 10 + 10 + 10 = 30 mm
Slant height = 9 mm
Substitute the values in the formula, we get the surface area
= 43.3 + 1/2 x 30 x 9
= 43.3 + 15 x 9
= 43.3 + 135
= 178.3 mm²

the value of a car that depreciates over time can be modeled by the function J(t)=27000(0.9)^2t+2. Write an equivalent function of the form J(t)=ab^t.
Answers
The value of a car that depreciates over time can be modeled by the function \(J(t)=27000(0.9)^{2t+2}\) has an equivalent form of \(J(t) = 21870(0.81)^t\).
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
The value of the car is given as:
\(J(t)=27000(0.9)^{2t+2}\)
The equation can be written as:
\(J(t)=27000(0.9)^{2t} (0.9)^2\\\\J(t) = 27000(0.81)^t(0.81)\\\\J(t) = 21870(0.81)^t\)
Hence, the value of a car that depreciates over time can be modeled by the function \(J(t)=27000(0.9)^{2t+2}\) has an equivalent form of \(J(t) = 21870(0.81)^t\).

a. a linear transformation t: is completely determined by its effect on the columns of the nn identity matrix. choose the correct answer below. t/f
Answers
False. A linear transformation is not completely determined by its effect on the columns of the identity matrix. While the columns of the identity matrix form a basis for the vector space, and determining their images under the transformation provides some information about the transformation, it does not provide a complete characterization.
A linear transformation is defined by its action on all vectors in the vector space, not just the basis vectors. The transformation can have different effects on vectors that are not in the span of the columns of the identity matrix. Therefore, knowing only the effect on the basis vectors does not fully determine the transformation.
To completely determine a linear transformation, one needs to know its effect on a set of linearly independent vectors that span the entire vector space. This set of vectors does not have to be restricted to the columns of the identity matrix. The transformation can be uniquely defined by specifying its values on these vectors, and then extended linearly to the entire vector space.

The linear regression equation for this set of data is y = 18.02x - 2.702.
The slope of a beach, to the nearest tenth of a degree, on a beach with grains of sand having a median diameter of 0.65 mm is equal to 9.01.
How to write the linear regression equation?In this scenario, the mean diameter of grains of sand (x) would be plotted on the x-coordinate of the scatter plot while the slope of beach (y) would be plotted on the y-coordinate of the scatter plot.
From the Excel sheet, you should right click on a data point on the scatter plot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.
By critically observing the scatter plot (see attachment) which models and shows the relationship between the mean diameter of grains of sand (x) and the slope of beach (y), the required linear regression equation is given by:
y = 18.02x - 2.702
For a median diameter of 0.65 mm, the slope of a beach (y) is given by:
y = 18.02(0.65) - 2.702
y = 11.713 - 2.702
y = 9.011 ≈ 9.01.

Answers
e) The test statistic and P-value for the chi-square test of homogeneity would be -1.75 and 0.004, respectively.
A chi-square test of homogeneity is a useful tool for comparing two or more categorical variables. In this case, the two variables are smoking (smokers and non-smokers) and alcohol consumption (those who had consumed alcohol in the past week and those who hadn't).
The chi-square statistic is calculated by finding the difference between the observed and expected frequencies of the two groups and squaring it. The expected frequencies are found by multiplying the sample size by the overall probability of success (in this case, drinking alcohol).
The P-value is then calculated based on the chi-square statistic and the degrees of freedom (in this case, one). In this case, the chi-square statistic is -1.75 and the P-value is 0.004.
