Engineers at a mining facility track important information about different types of equipment operating at the site. Because the information collected from each machine can include text, numbers, and logical values, the engineers store the data using a cell array.Below are several pieces of equipment currently operating at the mine:A haul truck manufactured by Caterpillar runs on diesel fuel and is capable of carrying 2 tons of mineral product per load.A tall mineral extractor tower stands 100 feet high, is not electrically powered, and cost $3,000,000 to install.A rock crusher built by Sandvik processes material with a weekly throughput of 12, 15, 16, 18, and 17 tons per day and uses an operating curve labeled “Type-B Compression Curve”.A conveyor belt system powered by electric motors moves ore at a rate of 35 tons per hour, passed safety inspections on [true true true false true] over the last five days, and is identified by the system name “Line-A Transport”.Determine the shape and quantity of the cell array based on the provided information.
