Assuming there were 26 measurements on concrete cylinders for each mixture. Alternative Hypothesis at α=0.01 will be rejected.
HypothesisElectrical resistivity(I)=6
Concrete cylinder measurement(J)=26
First step
Degree of freedom for SSb=I-1=(6-1)=5
Degree of freedom for SSw=I(1-J)=6(1-26)=150
Degree of freedom for SSr=IJ-1=(6×26)-1=155
Second step
Mean square(MSw)=13.929
SSw=MSw×I(J-1)
SSw=13.929×150
SSw=2,089.35
Third step
SSb=SSt-SSw
SSb=5,664.415-2,089.35
SSb=3,575.065
Fourth step
MSb=SSb(I-1)
MSb=3,575.065/(1-6)
MSb=3,575.065/5
MSb=715.013
Fifth step
F=MSb/Msw
F=715.013/13.929
F=51.33
The complete table is:
Source df Sum of squares Mean square F
Mixture 5 3,575.065 715.013 51.33
Error 150 2,089.35 13.929
Total 155 5664.415
Therefore, since 51.33 is greater than 11.97 we are going to reject the hypothesis at α=0.01.
Inconclusion Hypothesis at α=0.01 will be rejected.

Explanation:
Use series to approximate the definite integral i to within the indicated accuracy. i = 1/2 x3 arctan(x) dx 0 (four decimal places)
The expression [tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx[/tex] is an illustration of definite integrals
The approximated value of the definite integral is 0.0059
How to evaluate the definite integral?The definite integral is given as:
[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx[/tex]
For arctan(x), we have the following series equation:
[tex]\arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 1}}{2n + 1}}[/tex]
Multiply both sides of the equation by x^3.
So, we have:
[tex]x^3 * \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 1}}{2n + 1}} * x^3[/tex]
Apply the law of indices
[tex]x^3 * \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 1 + 3}}{2n + 1}}[/tex]
[tex]x^3 * \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}}[/tex]
Evaluate the product
[tex]x^3 \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}}[/tex]
Introduce the integral sign to the equation
[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =\int\limits^{1/2}_{0} \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}}[/tex]
Integrate the right hand side
[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =[ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}} ]\limits^{1/2}_{0}[/tex]
Expand the equation by substituting 1/2 and 0 for x
[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =[ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{(1/2)^{2n + 4}}{2n + 1}} ] - [ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{0^{2n + 4}}{2n + 1}} ][/tex]
Evaluate the power
[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =[ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{(1/2)^{2n + 4}}{2n + 1}} ] - 0[/tex]
[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{(1/2)^{2n + 4}}{2n + 1}}[/tex]
The nth term of the series is then represented as:
[tex]T_n = \frac{(-1)^n}{2^{2n + 5} * (2n + 4)(2n + 1)}[/tex]
Solve the series by setting n = 0, 1, 2, 3 ..........
[tex]T_0 = \frac{(-1)^0}{2^{2(0) + 5} * (2(0) + 4)(2(0) + 1)} = \frac{1}{2^5 * 4 * 1} = 0.00625[/tex]
[tex]T_1 = \frac{(-1)^1}{2^{2(1) + 5} * (2(1) + 4)(2(1) + 1)} = \frac{-1}{2^7 * 6 * 3} = -0.0003720238[/tex]
[tex]T_2 = \frac{(-1)^2}{2^{2(2) + 5} * (2(2) + 4)(2(2) + 1)} = \frac{1}{2^9 * 8 * 5} = 0.00004340277[/tex]
[tex]T_3 = \frac{(-1)^3}{2^{2(3) + 5} * (2(3) + 4)(2(3) + 1)} = \frac{-1}{2^{11} * 10 * 7} = -0.00000634131[/tex]
..............
At n = 2, we can see that the value of the series has 4 zeros before the first non-zero digit
This means that we add the terms before n = 2
This means that the value of [tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx[/tex] to 4 decimal points is
[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx = 0.00625 - 0.0003720238[/tex]
Evaluate the difference
[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx = 0.0058779762[/tex]
Approximate to four decimal places
[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx = 0.0059[/tex]
Hence, the approximated value of the definite integral is 0.0059

Suppose that we have this spinner. what is the probability of landing on 4 after landing on 4?
The probability that the spinner lands on 4 is its likelihood
The probability of landing on 4 after landing on 4 is 1/n^m
How to determine the probability?Assume that the numbers on the spinner are not repeated, the probability that a spinner lands on 4 is:
P(4) = 1/n
Where n represents the number of sections on the spinner
The probability that the spinner lands on 4 again is the same for the number of times the spinner is spun
Hence, the probability of landing on 4 after landing on 4 is 1/n^m where m represents the number of spins

Target profit is $100,000; total fixed costs are $120,000, and total variable costs are $500,000, the markup percentage is
The markup percentage to the variable cost using the variable cost method is 40%.
What is markup percentage?
The markup percentage to the variable cost using the variable cost method can be obtained by dividing the addition of the target profit and total fixed cost by the total variable cost as follows.
We know that:
Total fixed cost
= Fixed overhead costs + Fixed selling and administrative costs
= $120,000 + $50,00
= $170,000
The markup percentage to the variable cost
= (Target profit + Total fixed cost) / Total variable cost
= ($100,000 + $170,000) / $675,000
= $270,000 / $675,000
