Answer:
13
Step-by-step explanation:
(3 - 2i)(3 + 2i)
Expand
(9 + 6i - 6i - 4i^2)
Add
(9 - 4i^2)
Convert i^2
i^2 = ()^2 = -1
(9 - 4(-1))
Add
(9 + 4)
= 13

The correct labels are: Mean = C, Median = B and Mode = A
<h3>How to determine the labels?</h3>The image that completes the question is added as an attachment
From the image, we can see that the graph is skewed left
In a left skewed distribution,
- mean is less than the median
- median is less than the mode
This means that:
Mean is the smallest and mode is the highest
Hence, the correct labels are:
Mean = C, Median = B and Mode = A

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
