Which graph shows the solution to the system of linear inequalities? y < 2x – 5 y > –3x + 1 On a coordinate plane, 2 straight lines are shown. The first solid line has a negative slope and goes through (0, 1) and (1, negative 2). Everything to the right of the line is shaded. The second dashed line has a positive slope and goes through (0, negative 5) and (2, negative 1). Everything to the right of the line is shaded. On a coordinate plane, 2 straight lines are shown.

The Great Pyramid of King Khufu was built of limestone in Egypt over a 20-year time period from 2580 BC to 2560 BC. Its base is a square with side length 756 ft and its height when built was 481 ft. (It was the tallest manmade structure in the world for more than 3800 years.) The density of the limestone is about 150 lb/ft3. (a) Estimate the total work done in building the pyramid. (Round your answer to three decimal places.) × 1012 ft-lb (b) If each laborer worked 10 hours a day for 20 years, for 340 days a year, and did 250 ft-lb/h of work in lifting the limestone blocks into place, about how many laborers were needed to construct the pyramid?

A student is taking a multiple-choice exam in which each question has two choices. Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on a strategy in which she will place two balls (marked Upper A and Upper B) into a box. She randomly selects one ball for each question and replaces the ball in the box. The marking on the ball will determine her answer to the question. There are four multiple-choice questions on the exam. Complete parts (a) through (d) below. a. What is the probability that she will get four questions correct? nothing (Round to four decimal places as needed.)

Based on a survey, when 1009 consumers were asked if they are comfortable with drones delivering their purchases, 42% said yes. The probability of randomly selecting 30 of the 1009 consumers and getting exactly 24 who are comfortable with the drones is represented as 0plus. What does 0plus indicate? Does 0plus indicate that it is impossible to get exactly 24 consumers who are comfortable with drones?Choose the correct answer below.A.The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is impossible.B.The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is possible, but very unlikely.C.The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is likely.D.The probability 0+ indicates that the probability is zero. It indicates that the event is impossible.
