x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000. This can be obtained by understanding the question and observing the equations.
What do the x and y represent in the system?Given that total number of seats is 10,000 and there are two levels pricing.
Thus by observing the equation, x + y = 10,000,
10,000 is the sum of 2 variable which obviously will be the number of tickets in level 1 and number of tickets in level 2.
Since there are two level pricing,
50x + 150y = 75,000 represent the addition of total cost of tickets of level 1 and 2.
Hence x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000.

What is the slope of the line that goes through the points (-4,2) and (8,5)?
The slope of a straight line passing through the points (-4, 2) and (8, 5) is 1/4.
What is Slope of a straight line?
The slope of a straight line measures the rate of change of variable 'y' with respect to independent variable 'x'. Mathematically -
m = (y₂ - y₁)/(x₂ - x₁) = tan Ф
Given is a line that passes through the points (-4, 2) and (8, 5).
The slope of a straight line passing through two points is given by -
m = (y₂ - y₁)/(x₂ - x₁)
The coordinates given are (-4, 2) and (8, 5).
Substituting them in the formula, we get -
m = (y₂ - y₁)/(x₂ - x₁)
m = (5 - 2)/(8 + 4)
m = 3/12
m = 1/4
Therefore, the slope of a straight line passing through the points (-4, 2) and (8, 5) is 1/4.

The diagram of two similar triangles to complete the proportion is; Height of Person/Height of flower = Length of a person's shadow/Length of flowers' shadow.
How to solve similar triangles?From the concept of similar triangles, we know that If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor.
Applying this similar triangles theorem to our question, we can say that;
Height of a person/length of a person's shadow = Height of flower/length of a flower's shadow
We can rewrite this to get;
Height of Person/Height of flower = Length of a person's shadow/Length of flowers' shadow.

George bought socks for "$"300 and planned to sell them for $6 a pair. write an inequality to find the minimum number of socks he has to sell in order to make a profit of more than 210.
The inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.
In the question, we are given that George bought socks for $300.
Therefore, George's total cost = $300.
We assume the number of pairs of socks George sells to be s.
The unit price per pair quoted by George = $6
Therefore, George's total sales = $6s.
We know that the profit over a transaction is given as the difference between sales and costs, that is,
The profit = The total sales - the total costs,
or, profit = 6s - 300.
In the question, we are required to make a profit of more than 210.
This can be shown by the inequality,
6s - 300 > 210.
Thus, the inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.The values of the parameters are given as follows:
n = 5, x = 2, p = 0.5.
Hence the probability is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125[/tex]
