in 15 seconds they are 24 meters lower

The scatterplot demonstrates the strongest relationship is, a graph has x on the x-axis, and y on the y-axis. Points increase loosely together.

The correlation coefficient of scatterplot is used to demonstrate the relationship between variables.

When two variables increases together, they are said to have positive correlation.

When one is increasing and another is decreasing, they are said to have negative correlation.

When most of  data points form a straight line or lies close to the straight line, it indicates strong linear correlation.

From the given options;

Option A, zero correlation

Option B, less than 1

Option C, 1 or greater than 1

Option D, -1 or less than 1

Thus, the scatterplot demonstrates the strongest relationship between two quantitative variables is option C, "a graph has x on the x-axis, and y on the y-axis. Points increase loosely together".

=18

Answer:

176 tiles

Steps by step:

Step-by-step explanation:

2x + 1 = 9

2x = 9 - 1

2x = 8

x = 8 ÷ 2

x = 4

PLEASE

Answer:

Step-by-step explanation:

To solve:

|2x+1|=9

|2x+1|=-9

2x=8

x=4

2x=-10

x=-5

2x+1=9

2(4)+1=9

9=9, so its true.

2x+1=-9

2(-5)+1=-9

-9=-9, so it’s true too

Step-by-step explanation:

Pythagorean theorem.

a^2+b^2=c^2

This means that the square of the length of the 2 legs of a right triangle added together = the square of the length of the hypotenuses or diagonal.

If you know 2 of the values in the 3 variables a,b,c what would you do to find the missing variable value?

I will not write the exact answers to this problem. I think you can figure how to write it out yourselves.
