Answer:
Hence the probability that the mean weight of the sample of 55 cows would differ from the population mean by less than 12 lbs is 0.66545.
Step-by-step explanation:
x-3(2x-7)=76
distribute
x - 3*2x -3*(-7) =76
x -6x +21 = 76
combine like terms
-5x +21 = 76
subtract 21 from each side
-5x =55
divide by -5
x = -11
E and F and B are your correct answers, 40/60 equals 2/3 and F is a automatic choice answer, divide the n/d for letter E By 2 and you get 2/3. B is also correct if you divide the n/d by 6, you get 2/3. Enjoy the lesson and happy studying:)
