Is it possible to find out how long is the wall? The choices shown for the problem are: (a) 8 feet (b) 12 feet (c) 14 feet (d) 15 / 9 feet (e) None of these. Because I had put down (e) none of these.

What's the acceleration you're told to use in your class? 9.8m/s^2? 10m/s^2? 9.81m/s^2? I'll go with 10 because I'm lazy, just substitute to whatever you guys are using. The first ball (dropped from rest) will take 2 seconds to reach the ground : 20 = 5 x t^2 a...

x = x0 + v0*t + 1/2*a*t^2 x0=1.5 v0=-3 a=-10 (or something close, depending on what you're told to use in your class). You want the time for when x=0 (where 0m = the bottom of the window). 0 = 1.5 - 3 x t - 5 x t^2 1.5 = 3xt + 5xt^2 0=5t^2 +3t -1.5 You use the quadratic eq...

You didn't actually ask a question. Just saying.
Math
First, count the number of p and y in one pattern. Then, multiply these respective numbers by 4 because you need 4 times these patterns for one necklace. Then you multiply by 8 because you want 8 such necklaces. One pattern : y=4, p=10 One necklace : y = 4 x 4 = 16, p = 10 x 4...

variance = 4, so standard deviation = 2 (because squareroot of 4 is 2) 160 - 166 = -6 = -3 standard deviation. You take out a normal distribution table and you find out that a standard deviation of -3 or less happens only 0.13% of the time. Answer : 0.13%
algebra
230% of the distance from Boston to St. Louis = 2.3 times the distance from Boston to St. Louis With that information, you have that : 2.3 x (distance from Boston to St. Louis) = 2410 And you just divide both side of the equation by 2.3. 2410 divided by 2.3 is very close to 1048.
