Answer:
Part A: Based on the information collected, who will have the higher mean annual salary?
College graduates have a higher mean by about $20,000
Part B: If you were to graph this data, what would be important to consider?
The data should be graphed on the same axis and scale so comparisons are possible
Step-by-step explanation:
The answer is: D
Step-by-step explanation:
Direction: Opens Up
Vertex: (
−1/2, −25/4)
Focus: (−1/2, −6)
Axis of Symmetry: x = -12
Directrix: y = -132
Answer:
y = 3x - 4
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (2, 2) ← 2 points on the line
m =
=
= 3
Note the line crosses the y- axis at (0, - 4) ⇒ c = - 4
y = 3x - 4 ← equation of line
Answer: 4=40 ! Its a pattern
Answer:
-54
Step-by-step explanation:
Substitute the numbers for the variables.
-(5)+7(-7)
=-5-49
=-54
