Answer:
$120.50
Step-by-step explanation:
50 - 75 = -25
135.50 - 25 = 120.50
First you write down all even integers that divide 20.
Those are: 2,4,10,20
Since the request is that integer is less than n, 20 cannot be the answer.
This means that greatest even integer is 10
Answer is 10.
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.
