Jean forgot to pay her credit card bill. People who don’t pay their credit card bills on time, have to pay hefty interest charges! Her credit card company charges no interest if bills are paid on time, but it charges 22% if the bill is late (even if it is only 1 day!). When she paid the bill, with interest, she paid $756.40. What was the bill before she missed her payment? How much money did she lose because of this mistake?

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
