Step-by-step explanation:
There is 10 questions which in this case are the trials.
We know we can either get a question right or wrong so the two outcomes are right or wrong.
The probability that a student choose the right outcome is 1/4. since there is one right answer out of 4 chocies.choices.
Yes, the trials likelihood outcome of each outcome is the same. so it's independent
The Pythagorean theorem is helpful here.
.. x^2 +20^2 = 50^2
.. x^2 = 2500 -400 = 2100
.. x = 10√21 ≈ 46 . . . . feet
In line two, Madlime added positive one in the bracket, but subtracted one outside of the bracket without considering the factor outside of the bracket. Therefore, line 2 should be f(x)=3(x2+2x+1-1)-7
Line 3: f(x)=3(x+1)2-7-3
Line 4: f(x)=3(x+1)2-10
When you say something goes on forever, it means that it is going on to infinity. Infinity is something that can be used as a mathematical concept, but forever is not. Forever is something people say if they don't know how infinity is used.
