Select THREE that apply.

A
The line of best fit will have a positive correlation coefficient.

B
Each additional minute Tony spends in the record store is associated with an additional cost of $2.40.

C
The correlation coefficient for the line of best fit is 2.4.

There is a clown's face on the top of a spinner. The tip of his hat rotates to (−2, 5) during one spin. What is the cosine value
uranmaximum [27]
Remark
The point value is (-2,5) So we know the two sides. We need the hypotenuse. We should notice that the x value is minus (-2) and value is y value is plus (5). That means we are in quad 2. Be careful how you read that. (-2,5) is a point. It is not a tangent.

Step One 
Find the hypotenuse.

a = - 2
b = 5
c =  ??

c^2 = a^2 + b^2
c^2 = (-2)^2 + 5^2
c^2 = 4 + 25
c^2 = 29               Take the square root of both sides.
sqrt(c^2) = sqrt(29)
c = sqrt(29)

Step Two
Find the Cosine of the angle.
Cosine(theta) = adjacent / hypotenuse
Cosine(theta) = -2 / sqrt(29)  <<<<<<< Answer

Again, watch out for what you are given.

Answer:

  A)  6

Step-by-step explanation:

The ratio is found by dividing a sequence value by the one before. It is "common" if it is the same for any pair of sequence values.

  r = y2/y1 = 36/6 = 6

The common ratio is 6.
