The variable, the number of puppies, is modeled by an orange x tile. Giving away 1 puppy is modeled by 1 blue – tile. The expression that represents the situation is x – 1.
The first step in calculating the mean is to add the numbers. After that you divide by the number of items in the data set. You don’t need to group the numbers to find the mean. Hope this helped!
Two whole numbers will end up like this: 8x8=64,but multiplying a whole and a decimal will end up like this 8x8.1=64.1 or 8x8=8 to the second power. this should be sufficient information.
