Option B
When a increases, b tends to increase.
<h3><u>Solution:</u></h3>
Given that a strong positive correlation exists between "a" and "b"
Correlation coefficients are used to measure the strength of the relationship between two variables.
<em><u>Positive correlation:</u></em>
Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
When one variable moves higher or lower, the other variable moves in the same direction with the same magnitude.
Therefore if there is a strong positive correlation between "a" and "b" then When "a" increases, "b" tends to increase

Answer:
500
Step-by-step explanation:
10^3/2=500
Answer: (- 5, 4)
Justification:
The question asks for the coordinates of the image produced by the composed rotation - 270° o - 90° to the point (-5,4); that means applying a first rotation of - 90° and a second rotation of - 270°.
That composition of rotation is equivalent to one rotation of (- 270°) + (-90°) = - 360°.
A rotation of - 360° means 360° clockwise; that is a complete turn, to lead the original point to itself.
Then, the image of the point (- 5, 4) is the same point ( - 5,4)
