If Benny is 12 right now, that means that he is twice his sisters age because he is 200% of or 2 times his sister's age. His sister right now is 6 years old then.
After 4 years, Benny will be 16 (add 4 to 12) and his sister will be 10.
To find the percentage,divide his age by his sister's age and make it a percentage.
16/10=1.6=160%
Hope this helps.
Answer: The point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
Step-by-step explanation:
Let be the sample mean .
We know that the confidence interval for population mean is given by :-
, where E is the margin of error .
Given : Lower bound of the confidence interval = 0.226
Upper bound of the confidence interval =0.604
i.e.
Adding (1) from (2), we get
From (2),
Hence, the point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
