Answer:
The subscription began about 10 days before the 15th of the month.
Step-by-step explanation:
The correct option is:
The subscription began about 10 days before the 15th of the month.
The reason for being charged $60 instead of $45 which is the monthly rate is that they started the subscription prior the the cycle date of the bill period. Due to the change in the cycle date, the customer is getting a prorated charge for the days that had service prior to the date of the bill and current cycle starting

Step-by-step explanation:
First you would multiply 14 by 9 and you would get 162
Then you would Subtract 180 by 162 and you would get 18
So than you would keep on multiplying 10 till you get 20 which would be 2
So therefore your answer would be 2
To solve for the confidence interval for the true average
percentage elongation, we use the z statistic. The formula for confidence
interval is given as:
Confidence interval = x ± z σ / sqrt (n)
where,
x = the sample mean = 8.63
σ = sample standard deviation = 0.79
n = number of samples = 56
From the standard distribution tables, the value of z at
95% confidence interval is:
z = 1.96
Therefore substituting the known values into the
equation:
Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)
Confidence interval = 8.63 ± 0.207
Confidence interval = 8.42, 8.84
