1. It’s All In The Math submitted by Haily Vanderbur 1 – Pick a number of times you would like to eat out at a restaurant per week. It must be at least once, but not more than 10 times. 2 – Multiply that number by 2 (just to be bold.) 3 – Add 5 4 – Multiply it by 50 5 – If you have already had your birthday this year add 1763… If you haven’t, add 1762.

2. Continued 6 – Now subtract the four digit year that you were born. You should have a three digit number. The first digit of this was your original number (How many times you want to go out to a restaurant in one week). The next two numbers are YOUR AGE! (Oh, yes, it is!)

3. Algebra – 5.4 Fitting a line to data Objectives: -Find a linear equation that approximates a set of data. -Use scatter plots to determine positive, negative or no correlation. - Mr. Walker says that Scatter Plotting is: What happens to me when I’m planning revenge on someone but can’t focus.
