pie participation in informal 6.The National Science Foundation (NSF) sponsored a study on girls' science, technology, engineering, or mathematics (STEM) programs. The results of the study were published in Cascading Influences: Long-Term Impacts of Informal STEM Experiences for Girls (March 2013). The researchers sampled 174 young women who recently participated in a STEM program. They used a pie chart to describe the geographic location (urban, suburban, or rural) of the STEM programs attended. Of the 174 participants, 107 were in urban areas, 57 in suburban areas, and 10 in rural areas. a.Determine the proportion of STEM participants from urban areas. b.Determine the proportion of STEM participants from suburban areas. c.Determine the proportion of STEM participants from rural areas. d. Multiply each proportion in parts a-c by 360 to determine the pie slice size (in degrees) for each location. e.Use the results, part d, to construct a pie chart for geographic location of STEM participants. f.Interpret the pie slice for urban areas. g.Convert the pie chart into a bar graph. Which, in your opinion, is more informative? 7. All high way bridges in the US are inspected periodically for structural deficiency by the FHWA. Data from the FHWA inspections are compiled into the National Bridge Inventory (NBI). Classify each variable below as quantitative or qualitative. a. Length of maximum span (feet). b. Number of vehicle lanes. c. Toll bridge (yes or no). d. Average daily traffic. e. Condition of deck (good, fair, or poor). f. Bypass or detour length (miles). g. Route type (interstate, U.S., state, county, or city) 8. The NBI data were analyzed and the results made available at the FHWA Web site. Using the FHWA inspection ratings, each of the 608,272 highway bridges in the US was categorized as structural deficient, functionally obsolete, or safe. About 13.5% of the bridges were found to be structural deficient, while 3.5% were functionally obsolete. a. What is the variable of interest to the researchers? b. Is the variable of part a quantitative or qualitative? c. Is the data set analyzed a population or a sample? Explain. d. How did the NBI obtain the data for the study?

You may or may not have heard of Christo, but it's undeniable that he had a big impact on the art world. The Bulgarian-American artist, who passed away in May 2020, made a career out of combining art with engineering to produce sweeping, grand installations. Christo was born in Bulgaria but left with his family to take up residence first in Western Europe and then in the US. He became known as a "land artist)” someone who creates works of art not by painting existing landscapes, but by adding his or hey art to the landscapes themselves. In 1969, he created Wrapped Coast in Sydney, Australia. Working with a team of assistants, he took over part of the coastline (at Little Bay in Sydney and covered the entire area in a huge spread of synthetic fabric. The fabrie tovering the landscape encouraged people to see the area with a hew perspective. In addition, the way the fabric hid the ground while still revealing its bumps, fissures, and curves turned it into a landscape in the most essential sense, like a three-dimensional topographical map of itself. At the time, it was the biggest piece of artwork ever created. Christo continued to think big with Valley Curtain, another enormous piece of fabric pulled across a valley in Colorado, US, from one side to the other. More than 350 meters (m) wide and 100m tall, the curtain's construction was a lengthy and laborious process. During his first attempt to set it up, the fabric caught too much wind and blew away. When it was finally put into place, it lasted only a little more than a day before having to be dismantled again. Though Christo's artwork, like anything in life, did not last forever, it was extraordinarily impressive while it existed. Christo continued to create such pieces throughout his career. 000.000 A 48. Based on the passage, a land artist needs der er (A) personal experience as a construction engineer 000.000.1 Bt considerable knowledge about geography (C) the right landscape to create their pieces 000,008 the ability to create long-lasting pieces Der 000.000 49. What is said about Valley Curtain? (A) Christo's first attempt at it was a failure. (B) Christo used a fabric to cover an entire ground. (C) It covered the entire length of a long valley! (D) It used a three-dimensional topographical map. 50. What do we learn about Christo's artwork from the passage? (A) It was inspired by something he saw as a small child. 10 . (C) It made people think about environmental protection. (D) It showed people that art was rare and beautiful. D 51. Which of these pictures is most likely Christo's artwork? (A) (B) (C)
