Here is the two-part question... This counts as ONE homework grade and ONE quiz grade!
a. Take the following four numbers: 293, 471, 864, 348. If I told you that one of these numbers didn’t belong with the other three, which one would it be? Explain your reasoning with at least two complete sentences.
b. The geometric mean of two numbers can be found by taking the square root of the product of the two numbers. For example, the geometric mean of the numbers 9 and 25 is 15 because 9 times 25 equals 225 and the square root of 225 is 15. So you’re here’s your question… what are two sets of numbers where the geometric mean is equal to 32?
Good luck!
