Given that the <span>roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.
Given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.
Therefore, it will take you 12.94 minutes to get to the front of the line.

change the units to yards
21/3 = 7 yds
12/3 = 4 yds
A= 7*4 = 28 yds
cost = 29.56 * 28 = 827.68
the total cost is $827.68

Answer:
The standard error of the mean is 10.11 points
Step-by-step explanation:
Standard error of mean = t×sd/√n
sd = 115 points, n = 500, degree of freedom = n-1 = 500-1 = 499, assuming a 95% confidence level, t-value corresponding to 499 degrees of freedom and 95% confidence level is 1.96501
Standard error of mean = 1.96501×115/√500 = 10.11 points (to the nearest 100th)
