Like other graphs, they use an x axis, and a y axis. It shows how one variable can affect another, hence the x and y (independent variable versus the dependent variable). With scatter plots you can use it to find a line of best fit that shows an average correlation relationship of the data. Scatter plots also allow you to find any outliers (those little dots that aren't in a pattern, correlation, or area with the majority of other points). It usually shows a relationship between TWO sets of data. :) :>

Answer:
i believe C does not belong because it is the only one without x
Answer:
2.56x10=25.6
Step-by-step explanation:
Answer:
y = 8
x = 8√5
z = 4√5
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (y), x is a projection (16), and y is the other projection (4):
y 4
---- = -----
16 y
Cross multiply:
y² = 16 (4)
y² = 64
√y² = √64
y = 8
To find x and z, use the Pythagorean Theorem:
16² + y² = x²
256 + 8² = x²
256 + 64 = x²
320 = x²
√320 = √x²
√64√5 = √x²
8√5 = x
x = 8√5
4² + y² = z²
16 + 64 = z²
80 = z²
√80 = √z²
√16√5 = √z²
4√5 = z
z = 4√5
