Solve x^2 – 8x + 41 = 0 for x.
icang [17]
<span>\displaystyle x^2 - 8x + 41 = 0 \\\\ \Delta=b^2-4ac \\ \Delta=(-8)^2-4\cdot1\cdot41 \\ \Delta=64-164 \\ \Delta=-100 \\ \\ X_{1,2}= \frac{-b\pm i \sqrt{-\Delta} }{2a} = \frac{8 \pm 10i}{2} \\ \\ X1=4-5i \\ \\ X2=4+5i</span>

Please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
user100 [1]
Flip a coin twenty five times, the purpose of this is to show that theoretical and experimental do not always overlap.

Theoretically, it should be a fifty-fifty chance.

In the experiment because you do it a odd amount of times, 25, each flip will be worth a four percent chance.

You would not be able to make a fifty fifty chance with that amount of flips.

Also here:

1.) 13 Heads, 12 tails

2.) 48% chance for the coin to land on tails, 52% chance for the coin to land on heads.

3.) The theoretical probability of a coin landing on heads is 50% of the time that the coin is flipped. This is because there are two possibilities with an equal likelihood of happening 

4) The theoretical probability and experimental probability are different as theoretically there would be an equal likelihood or probability and in the experiement, there was a higher probability for the coin to land on heads.
