The process that Alexis should use to partition segment ab in the ratio 2:3 using a compass is; As detailed below
How to partition a Line Segment?To divide a line segment in 2:3 using compass, the steps that alexis has to follow these steps:
1) Draw any ray aₓ which makes an acute angle with segment ab.
2) Locate points a₁, a₂, a₃, a₄, a₅ on the ray aₓ such that aa₁, a₁a₂, a₂a₃, a₃a₄ and a₄a₅ are equal, with the aid of a compass.
3) Since alexis has to divide the line in ratio of 2:3, then the ray aₓ is divided into 5 equal parts.
4) Join the point b with the point a₅
5) From the point a₂, draw a line parallel to ba₅ and this can be drawn by making an angle equal to ∠aa₅b
6) Now, consider that the line that is drawn parallel to ba₅ intersect the given line ab at the point c.

What is the molar solubility of agcl (ksp = 1. 80 × 10⁻¹⁰) in 0. 500 m nh₃? (kf of ag(nh₃)₂⁺ is 1. 7 × 10⁷)
Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.
Given the following data:
Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰Concentration of NH₃ = 0.500Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷How to determine the molar solubility.First of al, we would write the properly balanced chemical equation for this chemical reaction:
[tex]AgCl(s)\rightleftharpoons Ag^{+} (aq)+ Cl^{-}(aq)[/tex] Ksp = 1.8 × 10⁻¹⁰
[tex]AgCl(s) + 2NH_3(aq)\rightleftharpoons Ag(NH_3)_2^{+}(aq)[/tex] Kf = 1. 7 × 10⁷
K = Ksp × Kf
K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷
K = 3.06 × 10⁻³
Mathematically, the Ksp for the above chemical reaction is given by:
[tex]K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}[/tex]

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

The sets A and sets B contains items called elements
It is true that the set A is equal to set B
How to determine the true statement?
The sets are given as:
Set A and set B
Since the sets have the same power set, then we have:
P(A) = P(B)
The above means that:
For every element X in A, then the element is also in B
And
For every element Y not in A, then the element is also not in B

(round your answer for f to two decimal places.)
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:

Find a parametric equation of the line m through p and q
The parametric equation of the line illustrates the independent variables x, y and z
The parametric equation of the line and direction is x = 5 + t; y = -1; z = 3 -2t
How to determine the parametric equation?The question is incomplete, as the points and the lines are not given.
So, I will make use of the following assumed parameters:
The line passes through: (5, -1, 3)The direction is ~v = <1, 0, -2>The parametric equation of the line is represented as:
r<x,y,z> = Line + t<direction>
This gives
r<x,y,z> = (5, -1, 3) + t<1, 0, -2>
Express the equation in terms of x, y and z
x = 5 + t * 1
y = -1 + 0 * t
z = 3 -2 * t
Solve the equations
x = 5 + t
y = -1
z = 3 -2t
Hence, the parametric equation of the assumed line and direction is x = 5 + t; y = -1; z = 3 -2t

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
= 0.40, or 40%.
