Answer:
Step-by-step explanation:
Let us first find the number of possible credit card numbers that can be formed with the numbers 0 - 9.
We want to form a 16 digit number out of 10 digits, so, we have:
There are 
numbers that can be formed.
There are only 100 million valid numbers (
). Let the number of valid numbers be n.
Therefore, the probability of picking a number that is valid is:
P(valid) = n / N
The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are <span>101,949 fewer people than those in first quarter.
This means that:
number of people who downloaded in 2nd quarter = number of people who downloaded in 1st quarter - 101,949
number of people in 2nd quarter = 351,875 - 101,949 = 249,926 people
Therefore, the total number of people who downloaded the app can be calculated as follows:
Total number = </span>351,875 + 249,926 = 601,801 people
Rounding this number to the nearest hundred thousands, we can get the estimated number of people who downloaded the app as 600,000 people
8585 is odd, so one of the primes is even and the other is odd (otherwise their sum would be even). 2 is the only even prime. Thus, second prime is 8585-2=8583. Their product is 8583*2=<span>17166.</span>
