Use the formula (zy)i<span> = (y</span>i<span> – ȳ) / s </span>y<span> and calculate a standardized value for each y</span>i<span>. Add the products from the last step together. Divide the sum from the previous step by n – 1, where n is the total number of points in our set of paired data. The result of all of this is the correlation coefficient </span>r<span>.</span>

Ksenya-84 [330]

Answer:

2:1

ratio of iced tea to lemonade= 12:6

now we reduce it to minimum by dividing it with same number.

12 is divisible by 6

pychu [463]
The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.

We know that,

Linear velocity = r x Angular Velocity
where r is the radius.

So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.

So, the correct answer is option C
