Eli says that the solutions to x^2+100=0 are 10 and -10 because 10^2 is 100. what error did eli make?

The answer would be an imaginary number because, using only real numbers, you cannot find the . So, Eli forgot to retain the negative or forgot you cannot solve .

Step-by-step explanation:

Even though 10^2 does equal 100, it does not satisfy the equation given:

69

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
