Identify any and all errors that marissa made in her steps. marissa should have only plotted the fractions on the number line. marissa should have used 30 as the common denominator. marissa should have listed the numbers from right to left after she plotted them on the number line. marissa should have used a common denominator of 30 and should have listed the numbers from right to left after she plotted them on the number line.

The map shows the location of the airport and a warehouse in a city. though not displayed on the map, there is also a factory 112 miles due north of the warehouse. a truck traveled from the warehouse to the airport and then to the factory. what is the total number of miles the truck traveled?

For the feasibility region shown below find the maximum value of the function p=3x+2y

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t. inv.2t to find the value of t for the interval calculation.
