if there are 200 questions and 4 marks for correct answers and -1 for incorrect answer and total marks is 250then what is the nu

The number of questions answered correctly = 90.

<h3>What is a system of linear equations?</h3>

A system of linear equations is a set of two or more linear equations.
Linear equations refer to the equations that involve two or more variables in the form of "ax + b".

Now,

Given:

Total number of questions = 200
Marks for correct answer = 4
Marks for incorrect answer = -1
Total marks = 250

To find : Number of correct answers = ?

Finding:

Now, assuming that the student attempted and answered all the questions,

Let the number of questions correctly answered be x and incorrectly answered be y.

Then,

x + y = 200 (For number of questions) (eqn 1)
and 4x - y = 250 (For the marks scored) (eqn 2)

Solving the system of linear equations:

For eqn 2, we get that y = 4x - 250

Substituting in eqn 1, we get:

=> x + 4x - 250 = 200

=> 5x = 250 + 200 = 450

=> x = 90

That is, the number of questions answered correctly = 90, the incorrect answers = 200 - 90 = 110.

Property taxes are based on the value of the property

Svetllana [295]

Based on the calculations, the average selling price for these properties is equal to $127,865.

<h3>How to determine the average selling price?</h3>

Mathematically, the average selling price for these properties would be calculated by using the following formula:

Average price = [F(x)]/n

<u>Note:</u> The total number of properties is equal to 5.

Substituting the given parameters into the formula, we have;

Average price = [118,450 + 126,500 + 128,000 + 130,425 + 135,950]/5

Average price = 639,325/5

Average price = $127,865.
