? what quantitative rule may be used to determine univariate outliers, and are there situations in which deleting a case/participant may be justified?
The Interquartile Range (IQR) rule is a commonly used quantitative rule to determine univariate outliers and deleting a case may be justified if it is a result of a measurement error, data entry error, or if it significantly skews the results.
The Interquartile Range (IQR) rule is a commonly used method for identifying outliers in a univariate data set. It is calculated as the difference between the 75th percentile (Q3) and the 25th percentile (Q1). Outliers are considered to be any values that fall outside of the range Q1 - 1.5 * IQR to Q3 + 1.5 * IQR. This range encompasses approximately 75% of the data, with outliers being any values that fall outside of this range.
In some cases, deleting a case or participant may be justified if it is a result of a measurement error, data entry error, or if it significantly skews the results.
This decision should be made carefully and only after careful consideration of the implications, as removing data can affect the validity of the results and the conclusions that can be drawn from the analysis. In some cases, it may be better to keep the outlier and consider it a potential error or to conduct further analysis to determine if there is a valid reason for the outlier.

exact shape function of tapered bar element
In FEM, nodal displacement is calculated using the matrix equation shown below: [K] is the global stiffness matrix, [u] is the displacement (solution) vector, and [F] is the vector of forces.
Describe function.A function is something that connects an input to an output.
Then, they are interpolated over entire elements using shape functions, which are essentially polynomials of different orders. Although quadratic shape functions, like a quadratic curve, are becoming common, linear shape functions, like a straight line used to approximate a distance between two locations, are the most fundamental. Even higher order shape functions (like cubic) exist, but they are rarely used in practical settings. The calculation of an element's stress uses Gauss Points rather than nodes. You can look up the GP locations for any given kind of element, but for the purposes of this discussion, let's just talk about singles.
Since [K] is the global stiffness matrix, [u] is the displacement (solution) vector, and [F] is the vector of forces, the matrix equation presented below is used to determine nodal displacement.

The solution of the periodic function is explained below.
A periodic function is a function that repeats its values after a certain interval of time, called its period.
The periodic function f(t) is defined on its period –2 ≤ t ≤ 2 and is described by the formula:
f(t) = t^2, when -2 ≤ t < 0
f(t) = -t^2, when 0 ≤ t ≤ 2
a) Plotting the function on the interval -8 ≤ t ≤ 8 would show us the repeating pattern of the function. To plot the function, we need to evaluate it for different values of t and plot the corresponding points on the coordinate plane.
b) The period of the function can be found by determining the smallest interval in which the function repeats. In this case, the period of the function is 2.
c) To determine whether the function is odd or even, we need to check if f(-t) = f(t) or f(-t) = -f(t). In this case, the function is an even function as f(-t) = f(t).
d) The mean value of the function on its period can be found by finding the average value of the function over one period. This is given by the formula:
(1/period) * ∫_0^period f(t) dt
e) The Fourier coefficients of the function can be found by using the formula:
ak = (2/period) * ∫f(t) cos(kπt/period) dt
bk = (2/period) * ∫f(t) sin(kπt/period) dt
f) The Fourier series of the function can be found by using the Fourier coefficients. This is given by the formula:
=> f(t) = a0/2 + ∑_(n=1)^∞
g) The first four terms of the Fourier series can be found by finding the first four values of the sum in the Fourier series formula. To find the explicit form, we need to evaluate the integrals and the sums.

Kit is baking cakes. She has 5 cups of sugar and each cake needs 3/4 cup of sugar. Determine the number of cakes Kit can make
Find 5÷3/4
Express your answer in simplest fraction form.
Answer:
Step-by-step explanation:
Im sorry I think it might be 2/4
Answer:
Step-by-step explanation:
To find the number of cakes Kit can make, we need to divide the total amount of sugar (5 cups) by the amount of sugar required for each cake (3/4 cup).
5 ÷ 3/4 = (5 × 4/3) ÷ (3/4) = 20/3 ÷ 3/4 = 20/3 × 4/3 ÷ 3/4 = 20/3 ÷ 3/3 ÷ 4/4 = 20/3 ÷ 1 ÷ 4/4 = 20/3 ÷ 1 ÷ 1 = 20/3 ÷ 1 = 20/3= 6 2/3 cakes
So Kit can make 6 2/3 cakes. This fraction cannot be reduced further, so it is the final answer.

Answer:
Step-by-step explanation:
For the first question, the combinations of bananas and apples that Elena could buy for exactly $3.50 are:
2 bananas and 2 apples (A)
5 bananas and 1 apple (F)
For the second question, Andre's statement is incorrect. The first type of bus holds 50 people and the second type of bus holds 56 people. In total, 3 of the first type of bus and 3 of the second type of bus can only hold 3 * 50 + 3 * 56 = 318 people. However, there are 280 elementary school students and 40 adults, which is a total of 280 + 40 = 320 people. Hence, Andre's statement is incorrect.
For the third question, the reason why equations A and B are not equivalent is because the variables in Equation B are expressed in a different form than in Equation A. Equation A shows the relationship between the variable x and the constant value 13 and 48, while Equation B only shows the relationship between the variable x and the constant value 35. To determine if they are equivalent, we need to solve both equations for x and compare the solutions. Solving Equation A gives us x = (48 + 13) / -5 = 5.6. Solving Equation B gives us x = 35 / 5 = 7. Since the solutions are different, the equations are not equivalent.
