8(2)-y=4
16-y=4d
-1y/-1=-12/-1
y=12
(16,12)
Answer:
The procedure results in a binomial distribution
Step-by-step explanation:
If all 120 couples used the YSORT method, it is fair to assume that the probability of a baby being a boy or a girl are constant through all trials (120 couples). Assuming 120 randomly selected couples, there is a fixed number of independent trials. Finally, since the babies can only be a boy or a girl, the binary condition is satisfied and thus, the distribution is binomial
Answer: 6.2 + 1.45 is 7.65% which as a decimal is 0.0765 so multiply that by 38550.
1.3n (it can be simplified like any other equation just add like terms and remember there is a one before every variable)
