A group of 8 friends went to lunch and spent a total of $76, which included the food bill and a tip of $16. They decided to split the bill and tip evenly among themselves.

Which equations and solutions describe the situation? Select two options.

A. The equation 1/8 (x + 16) = 76/8 represents the situation, where x is the food bill.
B. The equation 1/8 (x + 16) = 76 represents the situation, where x is the food bill.
C. The solution x = 60 represents the total food bill.
D. The solution x = 60 represents each friend’s share of the food bill and tip.
E. The equation 8 (x + 16) = 76 represents the situation, where x is the food bill.

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
