Answer:
Step-by-step explanation:
The range is 6 to 10 inches per month; 6 is the least amount of rain, whereas 10 is the most, for these four months.
Find the median by rearranging these four measurements in ascending order: 6 6 8 10. Since four is an even number (of measurements), we find the median by averaging the middle two measurements: (6 + 8) /2 = 7 in.
The mean is found by summing up the four measurements and dividing the result by 4:
6+6+8+10
-------------- = 30/4 = 7.5

Draw a histogram as two vertical bars, one of which is 3 units higher than the other. We don't yet know the total number of cats that each boy has, so your markings of your histogram have to be algebraic expressions, for example:
x + 0 for the first vertical bar and x + 3 for the second. Then, clearly, one boy has 3 more cats than does the other.
Corey has 3 more cats than Taylor. Let t represent the number of cats owned by Taylor and c the number by Corey.
Then t = c + 3 (general relationship), and so
6 = c + 3
We must isolate c to determine how many cats corey has.
Subtract 3 from both sides, which results in c = 3. Corey has 3 cats and Taylor has 6.
