Which of the following correlation coefficients represents the strongest
linear relationship?
-0.92
-0.45
0.88
0.16

Answers

Answer:

[tex]\boxed {\boxed {\sf -0.92}}[/tex]

Step-by-step explanation:

A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.

If it is a negative number, the linear relationship is also negative. If it's positive, the relationship is positive. The closer it is to -1 or 1, the stronger the relationship.

Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.

aster sold 18 oranges if this are 12% of her total oranges how many oranges are not sold​

Step-by-step explanation:

If 12% are sold then 100-12 = 88% are unsold.

1%   =  18/12 = 1.5 oranges,

88% = 1.5 * 88 = 132.

Write an absolute value inequality to describe the graph.

Answers

Answer:

A: |x - 6| ≤ 6

Step-by-step explanation:

Looking at the number line graph to interpret the inequality, since the plot is between -6 and 6, the mid value will be (-6 + 6)/2 = 0. Thus, we have;

0 - 6 < x - 6 < 6 - 0

This gives;

-6 < x - 6 < 6

Thus, writing in absolute value, we have;

|x - 6| ≤ 6

The slope-intercept form of the equation of a line that passes through point (–2, –13) is y = 5x – 3. What is the point-slope form of the equation for this line?

Answers

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

the point is (-2 , -13)

Point slope form is: y - y1 = m(x - x1)

y1= -13

x1= -2

y - -13 = 5 (x - -2)

y +13 = 5(x+2)
