Hallo! :D
In the last problem you asked and I answered, it had said that if we had a math problem with two variables, and we only solve for one, the other will end up in our answer.
Step 1) Add -3x to both sides.
Step 2) Divide both sides by 6.
Final Answer -
Hope this helps! :D
Answer: it would be shifted up
percentile)
Hence, in answering the stated question, we may say that As a result, the expressions value of P75 is 80.375.
In mathematics, you can multiply, divide, add, or subtract. An expression is formed as follows: Expression, number, and math operator Numbers, parameters, and functions make up a mathematical expression. It is possible to contrast phrases and expressions. Every mathematical statement that contains variables, numbers, and a mathematical action between them is referred to as an expression. For example, the phrase 4m + 5 is made up of the phrases 4m and 5, as well as the variable m from the provided equation, all separated by the mathematical sign +.
To determine the value of P75, or the 75th percentile, we must first determine the score at which 75% of the scores fall.
z = (x - μ) / σ
where x is the score to be converted, the mean, and the standard deviation.
As a result, we can write:
0.75 = P(Z ≤ 0.675)
where Z is the mean of the standard normal variable and the standard deviation is 1.
Now we can rearrange the z-score calculation to find the score x:
x = μ + zσ
Using the values we have:
x = 77.4 + (0.675)(5) (5)
x = 80.375
As a result, the value of P75 is 80.375.

Complex Numbers
There seems to be a mistake in typing. You probably type the letter "i" as "1", so it is difficult to tell which numbers are complex numbers.
I will however explain what complex numbers look like, which will help you in determining which numbers are complex numbers, and the rest are real numbers.
Step-by-step explanation:
Complex numbers are numbers that include the square root of a negative number.
It is not possible to have a value for an expression with a square root of a negative number, then the letter j or i were introduced to help represent these kinds numbers.
√-1 = i or j (anyone is fine)
Knowing the square root of -1 is i, we can write the square root of any negative number with ease.
√(-6) = √(-1) × √6, right?
= i × √6
= i√6
And so on.
So, basically, the numbers that include the letter 'i', or √(-1) in them are the complex numbers. The rest are real numbers.
