A retail chain lines its parking lots depending on the types of vehicles driven by local shoppers. Large trucks and SUVs require
bigger spots than compact cars. Each day, while collecting shopping carts, an employee records a list of the types of vehicles in the lot. Let the variable "Type" record whether a vehicle is a compact car, regular car, SUV, or large truck.(a) Identify whether the data are cross sectional or a time series.(b) Indicate if the variable is categorical, ordinal, or numerical (If a variable is numerical, include its units if possible).(c) List any concerns that you might have for the accuracy of the data.
Systems of linear equations can only have 0, 1, or an infinite number of solutions. These two lines cannot intersect twice. The correct answer is that the system has one solution.
