The answer here is A. since they are laying 100 bricks per hour, plus the 200 that they have already laid. Hope this helps!
Let us say T= probability of head turning up = 1/2 in one toss
H = probability of a tail turning up = 1/2 in one toss
Then P (56 heads or more) =
1/2^100 [ C(100,56) + C(100,57) + C(100,58) + ....
C(100,98) + C(100,99) + C(100,100) ]
where C(N, R) = N ! / [ (N - R)! R! ] number of occurrances of R formed from
N tosses.
Answer:
-7
Step-by-step explanation:
Because there is no multiplication, it is just the x^2 terms. There is a -(-2x^2) and a -9x^2, so it is 2x^2 and -9x^2 or -7x^2, so the coefficient is -7.
Answer:
The answer is C. Because I guessed and need points to ask other ppl...
Answer:
Yes, 14 squared is definitely bigger than 3.14. When you square a number, you multiply it by itself, and even if you didn't do that, 14 would still be a bigger number than 3.14.
