Answer:
most likely (c) 140 degrees
Answer:
CI=[0.8592,0.9402]
Yes, Method appears to be effective.
Step-by-step explanation:
-We first calculate the proportion of girls born:
Since np, we assume normal distribution and calculate the 99% confidence interval as below:
Hence, the confidence interval is {0.8598, 0.9402]
-The probability of giving birth to a girl is 0.5 which is less than the lower boundary of the confidence interval, it can be concluded that the method appears to be effective.
Factor pairs and add
1-6=-5
cool
answer is -6 and 1
Answer:
distribute first so it would be 18x-42=2
Step-by-step explanation:
