Answer: 4/5 (first choice)
=========================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(A) = BC/AC
sin(A) = 24/30
sin(A) = (6*4)/(6*5)
sin(A) = 4/5
A) The empirical rule tells you the probability of being within 1 standard deviation of the mean is 68%.
b) The probability that the sample mean falls within 3 standard deviations* of the mean is 99.7%.
___
* The standard deviation of the sample mean is 1/√9 = 1/3 of the standard deviation of an individual sample. Hence the same limits (90-110) now cover 3 standard deviations of the sample mean.

Answer:
If the parents are giving 2500, than Robin needs to save 9500 for the first year. She will be saving for 4 years, with 12 months in a year multiply 4 and 12. she will be saving for 48 months. divide 9500 by 48 you get 198. She needs to save 198 a month
