Hi, Probability that each each question is correct is 1/2. So, probability of gettign all 'n' questions correct is (1/2)^n So, (1/2)^n < 1000 => 2^n > 1000 2^10 = 1024 So, n >= 10 Minimum value of n is 10 . Can you please explain this stmt - "So, (1/2)^n < 1000 => 2^n > 1000"

Answer is D
Total revenue over the 10 day period: 400 * 10 = 4000
Total rev for first 6 days: 360*6 = 2160
Total revenue for the next 4 days = 4000 -2160 = 1840
Therefore, Avg revenue for the next 4 days = 1840/4 = 460

Ok, I'll do my best to make this legible. (27 - x) + (x - 8) + (3x + 11) = 3y --> 3x + 30 = 3y --> y = x + 10 2(x + 10) + 2/3(x + 10) = --> 2x + 20 + 2/3x + 20/3 = --> 8x/3 + 80/3 = --> (8x + 80)/3. Now you take that last number and divide it by 2 since you are taking the average of 2 numbers: (8x ...
