We can write any number n in the form 
, since 
and 
are inverse functions, so that
The bases are the same on both sides, so the exponents must be equal.
Solve for x :
Answer:
32
Step-by-step explanation:
To find the median, we need to put the numbers in order from smallest to largest
35, 33, 15, 32, 2, 28, 42
2, 15, 28, 32, 33, 35, 42
There are 7 numbers
7/2 = 3.5
So the 4th number is the median
2, 15, 28, 32, 33, 35, 42
32 is the 4th number
Answer:2,000
Step-by-step explanation:
Answer:
1. 15.1%
2. 8.3%
3. 12%
4. 25%
Step-by-step explanation:
1.
percent change = (new number - old number)/(old number) * 100%
percent change = (21300 - 18500)/(18500) * 100%
percent change = 15.1%
A positive percent change is a percent increase.
Answer: The percent increase is 15.1%.
2.
percent change = (new number - old number)/(old number) * 100%
percent change = (298000 - 325000)/(325000) * 100%
percent change = -8.3%
A negative percent change is a percent decrease.
Answer: The percent decrease is 8.3%.
3.
percent change = (new number - old number)/(old number) * 100%
percent change = (110 - 125)/(125) * 100%
percent change = -12%
A negative percent change is a percent decrease.
Answer: The percent decrease is 12%.
4.
percent change = (new number - old number)/(old number) * 100%
percent change = (1500 - 2000)/(2000) * 100%
percent change = -25%
A negative percent change is a percent decrease.
Answer: The percent decrease is 25%.
