Step-by-step explanation:
|...| means absolute value of "...". that means always the "+" value of "...", even if it is negative.
in other words
|-x| = x
|x| = x
|-x - 2y| for x = -2 and y = 3
|- -2 - 2×3| = |2 - 6| = |-4| = 4
Answer:a) mean=167.1
b)median=168.5
c)mode= 180
Step-by-step explanation:
Mean= total sum of values in the data set/ number of values
=2339/14=167.1
Median = midpoint = 165+172/2= 337/2= 168.5
Mode= number with the highest number of frequency, for this data set, 180 occurred most because it occurred three times
Answer:
$416
Step-by-step explanation:

6a=42
Step 2: Divide both sides by 6.
6a
/6
=
42
/6
Area of parallelogram<span>=</span><span>base x </span><span>height
Given :
Base = 12 in.
Height = 3 in.
Hence,
Area = 12 x 3
= 36 in. square</span>
