A family buys 4 airline tickets online. The family buys travel insurance that costs $16 per ticket. The total cost is $680. Let x represent the price of one ticket. Write an equation for the total cost. Then find
the price of one ticket.
Which equation represents this situation?
O A. 680 = 4(x + 16)
OB. 680 = 4x + 16
OC. 16 = 4x + 680
OD. 680 = 16(x + 4)
The price of one ticket is $1.

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
