Answer is 9 million telephone numbers: from 100-0000 to 999-9999. A 7-digit phone number is no different than a 7-digit number. Each digit can be unique. A 7-digit number can have 10 million combinations (from 0000000 to 9999999). The problem says to exclude all phone numbers starting with a zero ...

Usually, new found data that contradicts a scientific theory isn't enough to discount the entire theory. Scientific theories get formed after many data by many people that support its formation. So one disagreeing datum or "evidence" usually won't disprove it. Another way to understand this: a...
The probability of rolling a number greater than 8 on one roll of a pair of dice is 0.277777.... Let's see how we get that probability, and, though it may be a little long winded, it's important to understand what's going on. With one roll of a pair of dice, we have 36 possible outcomes. They are 1...
Crude birth rate is how many live children are born. Crude death  rate is how many people die. Crude death minus crude birth is the  net gain (or loss) and is called the birth rate. It represents  whether or not deceased people are "replaced".

MEAN: The mean is the average of a group of numbers. How to do it example: Let's use the numbers 10, 5, and 6. Now add them up and what do you get? 21. Divide 21 by 3, since you started out with 3 numbers. What do you get? 7. 7 is your mean (average). MEDIAN: The median is the middle of the numbers...
