Answer:
Step-by-step explanation:
The mode is the number of most repeated data in the set.
Given set 2, 1, 4, 7, 1 has mode 1 (repeated twice).
If we add 1 to the set the mode will remain 1 as it will repeat three times, so the mode won't change.
There is no change in mode, so the mode decrease is zero.
(2x-1)(2x+1)
the answer is c
3x+s
should be the answer hope it helps
the simple equation you have to do is
0.15 x 50,000 or 15% of 50,000 of which both equations will result in 7500
