Upon brainstorming, three of them namely Aries, Kim and Chen suggested to design a human-shaped bread (normal design), the other two Anton and Jade suggested a robot-shaped cookie design. In compromise with the two design ideas, they have come up with the hybrid sketch below. Each of them took up the task of calculating the area of the gingerbread. Solve for the ff: 1. Aries's task is the area 1 (refer to figure 1.2) which are the leg of the bread. 2. Kim's task is the area 2 (refer to figure 1.2) which is the body of the bread. 3. Chen's task is the area 3 (refer to figure 1.2) which are the arm of the bread. 4. Anton's task is the area 4 (refer to figure1.2) which is the box head of the bread. 5. Jade's task is the area 5 (refer to figure 1.2) which are the antennae and the semicircular ears of the bread.…
- At a college basketball game, one lucky ticket holder will win an all-expenses-paid trip to the conference championship game. There are 4,000 ticket holders at the game. The organizers want to place chips, each labeled with the seat number of a ticket holder, in a bin and draw the winner from the bin. Unfortunately, the bin will hold only 400 chips. Which method assures both that the organizers can use the bin for the drawing and that each ticket holder will have a fair chance of winning? A. Place chips labeled with the seat numbers of each ticket holder into 10 groups based on age. Then randomly select one of the groups and place it in the bin. Randomly select the winner of the trip from the bin. B. Randomly assign the 4,000 ticket holders to 40 equal-sized groups. Then randomly select 4 of the groups and place their seat numbers in the bin. Randomly select the winner of the trip from the bin. C. Place 400 chips labeled with the seat numbers of ticket holders from a…Pigmented makeup products like mascara and eye shadow may contain metal (e.g., nickel) allergens.

Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

- Chapter 6, Section 4-HT, Exercise 218 - MathPad Mind-Set MattersIn 2007 a Harvard psychologist set out to test her theory that ‘‘Mind-Set Matters.”1 She recruited 75 female maids2 working in different hotels to participate in her study, and informed 41 maids (randomly chosen) that the work they do satisfies the Surgeon General’s recommendations for an active lifestyle (which is true), giving the maids examples on how their work qualifies as good exercise. The other 34 maids were told nothing. After four weeks, the exercise habits of the two groups had not changed, but the informed group had lost an average of 1.79 lbs (s=2.88) and the uninformed group had lost an average of 0.2 lbs (s=2.32). The data are stored in MindsetMatters. Based on this study, does ‘‘Mind-Set Matter”? In other words, for maids, does simply thinking they are exercising more actually cause them to lose more weight?Click here for the dataset associated with this question.1Crum, A. and Langer, E.,…Windy, part III Exercises 12 and 14 give summaries anddisplays for two potential sites for a wind turbine.

They had participants drive in a simulator while talking on a hands-free cell phone and while not talking on a phone. The same people participated over several days, so they had a chance to practice this multitasking. On the first day, they were considered to be least experienced; on the last day, the most experienced. On the last day, they were tested in both a familiar environment and a slightly different driving environment to see if the first days of practice would transfer to a new context. The researchers collected data on how many collisions (accidents) the drivers got into on the simulator. All of the data is in the picture below!! Please answer the following questions about the study! 1. What kind of design is this? (put your answer in the form ___X___ 2. What are the Vs and their levels in…
