Answer:

C) Negative

Step-by-step explanation:

<u>Explanation</u>:-

<u>Correlation</u>:-

Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together

<u>Positive correlation :-</u>

Positive correlation occurs when the two variables of a function move in opposite directions. As the value of 'x' increases ,the Value of 'y' increases. Like wise the value of 'y' decreases, the value of 'x' decreases.

<u>Negative correlation:-</u>

Negative correlation occurs when the two variables of a function move in opposite directions. As the value of 'x' increases ,the Value of 'y' decreases. Like wise the value of 'y' decreases, the value of 'x' increases.

<u>Final answer</u>:-

If the linear correlation between two variables is negative then the slope of the regression line is also positive.

Step-by-step explanation:

The system of equations for eq 1 which is 3x + y = 118 represents the Green High School which filled three buses(with a specific number of students identified as x) and a van(with a specific number of students identified as y) with a total of 118 students.

for eq 2; 4x + 2y = 164; represents Belle High School which filled four buses(with a specific number of students identified as x) and two vans(with a specific number of students identified as y) with a total of 164 students.

The solution represents the specific number of students in the buses and vans in eq1 and eq 2 with x being 36 students and y being 10 students.

substituting 36 for x and 10 for y in eq 1;

3(36) + 10 = 108 + 10 = 118 total students for Green High School

substituting 36 for x and 10 for y in eq2;

4(36) + 2(10) = 144 + 20 = 164 total students for Belle High school

5t 8=43 whats t.I WILL GIVE 50 POINTS AND IF YOU DONT RECEIVE THE POINTS TELL ME AND I WILL GIVE THEM.PLZ HELP MEEEEEEEEEEEEEEEE

==> I can't be sure of the equation.  There's a blank space
        between '5t' and '8', where an operation must be.
       I think the operation is more likely ' + ' (addition).  Brainly usually
       does show the ' - ' if it's subtraction, but goes blank if it's addition.
       Tell you what I'll do:  Since you sound so desperate, and you're being
       so generous with your points,  I'll show you how to figure it out both ways.

----------------------------------------

If it's subtraction:                 5t - 8 = 43

Add  8  to each side:              5t      = 51

Divide each side by  5 :            t     = 51/5

                                                 t     = 10 and 1/5

--------------------------------------------

If it's addition:                         5t + 8  =  43

Subtract  8  from each side:     5t        =  35

Divide each side by  5 :             t        =   7
