Answer:
11
Step-by-step explanation:
This is a difference of squares and therefore can be written as (76-1)(76+1)=(75)(77).
So lets look at the factors....
75=3(25)=3(5)(5)
77=7(11)
The biggest prime factor is therefore 11.
Identities used:
Difference of squares a^2-b^2=(a-b)(a+b)
11/12 - 7/12 = 4/12 = 1/3

10(1/2x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = - 52
x = -52/5
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
