The size of the sample is 20C_5 or 15504 if the five kids is randomly chosen from a class of 20 students. An outcome of the selection process is the set of five kids selected.
What is permutation and combination?A permutation can be defined as the number of ways a set can be arranged, order matters but in combination the order does not matter.
We have total number of students in a class = 20
An outcome of the selection process is the set of five kids selected.
A team of 5 kids choosen from a class of 20 students in [tex]_{20}^{}\textrm{C}_5[/tex]
So the size of samples = [tex]_{20}^{}\textrm{C}_5[/tex] = 15504
Thus, the size of the sample is 20C_5 or 15504 if the five kids is randomly chosen from a class of 20 students. An outcome of the selection process is the set of five kids selected.

two positive charges of 1 mc and 10 mc are separated by a distance of 10 m. find the direction and the magnitude of electrostatic force between the charges. describe the direction in terms of "the charges attract each other," or "the charges repel each other."
By Coulomb's law, we will see that the force is 898.8 N, and the charges repel each other.
How to get the force between the charges?
Coulomb's law says that the force is:
[tex]F = k*\frac{q_1*q_2}{R^2}[/tex]
Where k is a constant, the q's are the charges of each particle, and R is the distance between the particles.
We have:
q₁ = 1 mc = 1*10^{-3} Cq₂ = 10 mc = 1*10^{-2} CK = 8.988*10^9 (N*m^2/C^2)R = 10mThen the force is:
[tex]F = 8.988*10^9*\frac{1*10^{-3}*10^{-2}}{(10)^2} N = 898.8 N[/tex]
And because both particles have positive charge, the charges repel each other.

Hardy-Weinberg equilibrium is a theoretical model for population genetics and includes random mating.
What is the Hardy-Weinberg equilibrium?It explains the temporal dimension and implies the prediction of the composition of the gene pools that define the population at a future instant based on its initial situation.
The Hardy-Weinberg model is based on the fact that the population is panmictic, that is, all individuals have the same probability of mating and mating is random (panmixia).

Using a linear function, it is found that 1466 gallons of water were in the tank when jabria began adding water.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we have that in 12 minutes, the amount of water increased by 3456 gallons, hence the slope is given by:
m = 3456/12 = 288.
In 7 minutes, the tank contained 3,482 gallons of water, hence the initial amount was given by:
3482 - 7 x 288 = 1466.

The Levelized Cost of Energy (LCOE) gotten from the given parameters is; $0.06 per kWh
How to find Levelized Cost?We aregiven;
Capital costs of the Solar Energy Project = $ 995,000.
Average yearly operating costs = $ 175,000.
We are told that the project is estimated to run for 25 years, producing a total 89,500,000 kWh.
Formula for Levelized Cost of Energy is;
LCOE = (Capital Costs + (Average yearly operating Costs * Number of project years))/Total Production
LCOE = (995000 + (175000 * 25))/89500000
