A=P(1+r/n)^(n*t); this is the formula for calculating compound interest. This means the total amount is 1000*(1+(1/10)/1)^(1*2)=1000*(11/10)^2=1000*121/100=10*121=1210 dollars. So your total amount would be 1210 dollars.

Well, first, triangleMOQ is the same as triangleNOR. We can use this similarity to say QO = RO. Aksi we know PR=15, and since N bisects PR, NR=7.5. We can write an equation which states OR^2=(7.5)^2+ON^2. Also, QO+ON=10 so RO+ON=10. Now that we know this, RO has to be more than 7.5 but less than 8.25. Try solving using that and you will have to do a bit more work.

Are you sure it is. My friend said he came up with it for me. I'm not saying he wouldn't lie to me, but I don't think he would be untruthful. Idk though.

Ik, I swear when I tried to post this I had the whole thing up, and this is a repost bcz I was trying to see whether it would fix but both times I posted the question nothing was there after the -pi/2. It's supposed to be -pi/2

Well, there are 4c2=6 total duos. For the duos with 1, they all work. That's 3 duos already. For 2, it divides 4 so that's 1 more duo and we have 4 duos now. But now 3 doesn't divide 4 and there are no more combinations. So the probability is 2/3.

I don't think it does that type of a thing. I know what you are talking about though. I feel like this site has become more for answering questions than used as a calculator.

First, the probability of getting a green marble first is 33/66 or 1/2, then the probability of getting a blue marble after that is 22/65. So (1/2)*(22/65)=11/65. So the probability is 11/65.

We can rewrite that as x^2+4x-20>0. The answer is x>-2+2sqrt6 or x<-2-2sqrt6. There are 2 solutions since we got a quadratic equation in the inequality.
