I'm pretty positive it would be the second one from the top
Answer:
10,000
Step-by-step explanation:
The combination consists of four digits, hence 0000 to 9999. There at 10^4 or 10,000 possible combinations (but only one that works).
Answer:
5 • 10^6
Step-by-step explanation:
When we talk about approximations, it is important to know that their purpose is not to find the correct value, only close enough that will do the job. We use them when we want to write something in a shortened way, to save time or when it's impossible to find precise value. Of course, our approximation won't be 100% precise, but it will be acceptable.
So, in this case, we are dealing with a population that is just above five million.
Milion (1 000 000) is a seven-digit number written with six zeros, so its power of ten will be 10^6 (ten to the power of six).
Since the population is around five million, we will approximate it to
5 • 10^6 (five times ten to the power of six)
