ANSWER
B. x=3,y=2
EXPLANATION
The given equations are

and

We add the two equations to eliminate y.
This implies that that:

Simplify:

Divide both sides by 2.

We put x=3 into any of the equations to find y.
Let us substitute x=3 into equation (1) to get:



Divide both sides by -3 to get;

The solution is therefore x=,y=2.
A whole number is a whole positive number (0, 1, 2,3 ,4....)
Integers are any whole number (negative or positive)
The answer is false
because an integer like - 4 is not a whole number
The degrees of freedom in testing for differences between the means of two dependent populations where the variance of the differences is unknown are: df = n - 1
<h3>What is the degree of freedom for dependent variables?</h3>
In statistics, degrees of freedom refers to the number of distinct values that can change in an evaluation without exceeding any constraints.
The degree of freedom is crucial and necessary when attempting to comprehend the significance of a test statistic and the validity of the null hypothesis.
In testing for differences between the means of two dependent populations where the variance of the differences is unknown, the degrees of freedom are: df = n - 1

Answer:
It means P ! / N! / K Because of the language
The answer is DE/DF, which I'm assuming is option D. This is because sin is opposite/adjacent.
