Any positive number times infinity is infinity. \overline 9 is a positive number.

The numerator and the denominator of 3/2 are being multiplied by 1^2, 2^2, 3^2, 4^2, ...

You say that you are planning on dividing the 7 by 0.15, but instead you divided by 15!

You seem to be correct about the dealer getting two cards these days. I might be wrong but I recall that in the 80's that the dealer only got one card. Thanks for updating this for me!

Actually the dealer gets one (up) card. After all the players are done, then the dealer takes their 2nd card (unless everyone already lost)

Why can't 4 cards be drawn? One player and the dealer--the player stands with 18 (say two 9's) and the dealer gets 2 picture cards. Why is 13 the max? 6 players plus the dealer--why can't each player get 5 cards each? Suppose player 1, 2, 3 and 4 gets an A, 3, 5, 7 and 10, and player 5 and 6...

There are nothing but If's in the post. The conclusion does follow but as you said, is it relevant to this thread?

What are the 5 outcomes and why exactly 3 ways to win?

You didn't mention anything about someone wanting any numbers from a list. I can only assume that the list is from 1 to 13(?????) In the red above you mentioned him. Is this him the same person whom gave you the code??

I think that I need to retake (and retake) our mind reading class for this one.

Let x = the number of pencils you produce. Let y = the number of pens that you produce. The company produces at least 30 packs of pens each day but no more than 40. 30<y<40 The company produces at least 90 packs of pencils each day but no more than 110. ???? A total of less than 130 packs of...

That is correct. You slipped in that AND without my seeing it.

What is the probability that both teams win the Stanley Cup??

You might also need the fact that cos2A = (1+cos(2A))/2

f(x) = |x| + |x + 1| + |x + 2| ... |x + 55| f(0) = 1+2+...+55 f(-55) = 55 + 54 +...+1 (same as above) Letting x>0 will give a larger answer than above. Now consider x values such that x<0. If you think about it, you'll realize that x>-55 Now go and get your hands dirty.

The answer is 9. Why would anyone here think otherwise.

Squaring just one side of an inequality usually doesn't work.

Forget the - signs for a moment. Then the sequence is 1 2 3 4 5... Clearly the nth term in my sequence will be n. You get to show how you would decide if the n is + or -.

What rule changed? -5-5 is not 0. -65-65 is not 0. 5-5=0 and 65-65=0. For the record, -5 +5=0

This is a help forum where we help students solve their problems as compared to doing it for them. Did you read the posting guidelines? To compute the fifth root of 243 you want to find a single number that when you multiply it by itself 5 times will give you 243. That single number will be...
