Does anyone know?

I have several dozen wooden cribbage boards (tournament long boards).

Someone (with the best of intentions) wrote crude marks with a ballpoint pen on the boards ... which I'd like to remove. Painting isn't a realistic option. Is there a simple method to remove these ballpoint pen marks?

I've done minor edits for Wikipedia (all logical and legitimate), but would like to completely rewrite an existing article to make it far more informative. What is the best procedure to follow in order to accomplish this task?

Given: Automobile insurance payments in an area averaged $7,400 for 15 cars with a standard deviation of $4,800.

Question: Using 95% confidence, what is the margin of error? (round to 2 places).

Here is what I have as the answer:

Using n = 15, μ = 7,400, σ = 4,800, Zα/2(.95) = 1.96

E = Zα/2 (σ/√n)

E = 1.96 (4800/√15)

E = 1.96 (1239.35)

E = 2429.13

This is showing as wrong, as is 2429.14.

Any help is appreciated.

You are pone and are holding 6 7 8 9.

What card do you lead (and why)?

I'm going to the Insight Bowl this year. (Have gone before, live in the Phoenix area).

Have no feelings good or bad towards either team.

Who should I root for and why? Give a good,coherent answer that will convince me to cheer for one team during the game.

Seriously. Every time I read anything about Victoria Jackson lately, she's going on about some crazy conspiracy or three. Has she been diagnosed with a mental condition?

for the problem: 1 - x^2 - x - y^2 + y

I get:

fx(x,y) = -2x - 1

fy(x,y) = -2y + 1

fxx = -2

fyy = -2

correct so far?

if so, is fxy 0 or -2?

I sort of remember an old Japanese monster movie. A kid is flying a kite and is attacked by a flying monster.
