Answers

area A / area B = 2 / 1; => radius A / radius B = $√(2)$ ;
circumference of circle A / circumfereance of circle B = radius A / radius B = $√(2)$ => $√(2)$ ≈1.41;

Solve the equation A = 2LW + 2LH + 2WH for H.a) H = A - 2LW/2L + 2W

Answers

The relationship which could be described using correlation, r is; Choice C; High temperature of the day and number of zoo visitors that day.

What is correlation

Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate). It's a common tool for describing simple relationships without making a statement about cause and effect.

Correlation is characterized by the two variables being quantitative variables.

Hence, since High temperature of the day and number of zoo visitors that day are quantitative, the relationship can be described as correlative.
