What is the best estimate for the value of r in the scatter plot?
Wittaler [7]

From the observation of the dispersion graph it is concluded that the answer to this question is option D. r = -0.5.

The correlation coefficient "r" is a measure of the linear relationship between two random variables.

When the correlation is positive, the value of "r" is between 0 and 1. This means that when one variable increases the other too.

When the correlation is negative, the value of "r" is between -1 and 0. This means that one variable decreases as the other increases.

When there is no correlation the value of "r" is 0


In this case, the dispersion chart shows that the variable "y" decreases as the variable "x" increases. Therefore the value of "r" must be negative. Of all the options, the only one that presents a value of negative r is option D:

 r = -0.5

The first term in a sequence is -2 and the common ratio is 3. What is the sixth term of the sequence?
AlekseyPX
It's the Geometric Sequence.

The n<span>-th term of a geometric sequence with initial value </span>a<span> and common ratio </span>r<span> is given by:
</span>
a_n=a_1\cdot r^{n-1}\ for\ n\in\mathbb{N^+}

We have:

a_1=-2;\ r=3;\ n=6

Substitute:

a_6=-2\cdot3^{6-1}=-2\cdot3^5=-2\cdot243=-486

Answer: The sixth term is equal -486.

Factor completely. 5x^2-20x+20=5x 2 −20x+20
Harman [31]

Step-by-step explanation:

5x^2 - 20x + 20 = 5x^2 - 20x + 20

5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)

(5 + 5) (x^2 - 4x + 4)

If m || n and m &lt;8 = 115°, what is m &lt;2
Anestetic [448]

Answer: OPTION B.

Step-by-step explanation:

When parallel lines are cut by a transversal several angles are formed.

There are pairs of angles called "Alternate Interior angles".

 These angles are not adjacent and they are located between the parallel lines, and on opposite sides of the transversal.

By definition, they are are congruent, or, in other words the measure of Alternate Interior angles are equal.

In this case, you can identify that the \angle 8 and the \angle 2 are Alternate Interior angles.

Based on the data given in the exercise, you know that the measure of the angle 8 is:

 \angle 8=115\°

So, You can determine that the angle 2 have the same measure. This is:

 \angle 2=115\°
