Answer:
median and/or mean of the data
Step-by-step explanation:
The spread is the range of the data. And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform.
Answer:

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (5, - 7 ) and (x₂, y₂ ) = (- 3, 2 )
m = = = - , then
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 3, 2 )
2 = + c ⇒ c = 2 - = - = -
y = - x - ← equation in slope- intercept form
multiply through by 8 to clear the fractions
8y = - 9x - 11 ( add 9x to both sides )
9x + 8y = - 11 ← equation in standard form
Answer:
We need to evaluate this: [(-16)+4] / [(-2)+5]
First, we do the brackets:
[(-16)+4] = -16 + 4 = -12
[(-2) + 5] = -2 + 5 = 3
Now, we only need to divide, as we have calculated both brackets:
-12/3 = -4
(Remember that when dividing a negative number by a positive one, we always obtain a negative)
So the result is -4
Answer:
The angles are : 30° , 60° , 90°
Step-by-step explanation:
Sum of angles in a triangle = 180°
Given: the angles are in the ratio = 1 : 2 : 3
Sum of the ratio = 6
Therefore , the angles are
1)X×Y that is the equation
