In a random sample of 106 social (or service) robots designed to entertain, educate, and care for human users, 63 were built with legs only, 20 with wheels only, 8 with both legs and wheels, and 15 with neither legs nor wheels. One of the 106 social robots is randomly selected, and the design (e.g., wheels only) is noted. c. What is the probability that the selected robot is designed with wheels? d. What is the probability that the selected robot is designed with legs?

Quantity takeoff

Quantity takeoffs (QTO) are precise estimates of the materials and labor costs required to finish a construction project. During the pre-construction phase, an estimator prepares them, breaking down the project into smaller, more manageable parts that are easier to evaluate. These measurements are used to prepare a construction scope bid. Estimators examine the drawings, specifications, and models to figure out different quantities and their costs. Since, the components, their quantity, and price are all included in the model, quantity take-off can be done automatically using Building Information Modelling (BIM). The time taken for completing a construction project can be reduced by the use of quantity takeoff. These takeoffs are also called material takeoffs and construction takeoffs.

An Atwood's machine was used by a student to determine the acceleration of two masses, m₁=73 grams and m2=70 grams. The pulley rotates freely, and the masses were released from rest and the vertical distance traveled by the masses is 80 cm. The student conducted 5 trials to measure the time it took the masses to travel the vertical distance of 80 cm. The measured time were 3.23 s, 3.08s, 3.43s, 3.29s and 3.67s. If the mass of the pulley is 95.74 grams determine: a. The experimental value of the acceleration b. The true value of the acceleration c. the percent difference between the experimental and true values of acceleration.
