While working on the multiplication problem 38 x 25, Maria says this: “Four times 25 is 100, so 40 times 25 is 1000. Now take away 2, so the answer is 998.” Is Maria’s method correct or not? If it is correct, write equations that incorporate Maria’s work and that show why it’s correct. If Maria’s reasoning is not correct, explain why. Work with portions that are right to correct Maria’s work, and write a string of equations that corresponds to your corrected method for calculating 38 x 25. In either case, write your equations in the following form:

We've studied two different basic types of research studies, Observational Studies and Experiments. They have similarities and differences in their methodologies, and in some cases it is not practical nor ethical to design a study one way or the other. And this affects the kinds of conclusions the research can ultimately reach. This discussion is designed for students to help each other build a complete understanding, and clearly separate these as two distinct concepts. Discuss the similarities and differences between these, as well as the research conclusions to which they can possibly lead.
Please help with correct answers in details: Step by step. Last time i submitted i got wrong answers The product development group at Landon Corporation has been working on a new computer software product that has the potential to capture a large market share. Through outside sources, Landon's management learned that a competitor is working to introduce a similar product. As a result, Landon's top management increased its pressure on the product development group. The group's leader turned to PERT/CPM as an aid to scheduling the activities remaining before the new product can be brought to the market.
Formulate but do not solve the problem.In a survey of 1000 adults aged 18 and older, the following question was posed: "Are other travelers' online reviews trustworthy?" The participants were asked to answer "yes," "no," or "not sure." The survey revealed that 330 answered "no" or "not sure." It also showed that the number of those who answered "yes" exceeded the number of those who answered "no" by 410. What percentage of respondents answered "yes," "no," and "not sure"? (Let x represent the number of respondents who answered "yes", y represent the number of respondents who answered "no", and z represent the number of respondents who answered "not sure".) = 1000 = 330 = 410

PROBLEM 03: The Jokia Cell Phone Company manufactures two models of cell phones - the Wombat and the Sloth. Each Wombat phone uses 2.5 ounces of gold leaf and 3 ounces of plastic, whereas each Sloth phone uses 2 ounces of gold leaf and 2 ounces of plastic. Each day, the company has only 370 ounces of gold leaf and 420 ounces of plastic to be used for making cell phones. If the company makes the correct number of each type of phone on a given day to use up all of the available gold leaf and plastic, how many Wombat phones will be made? A) 60 B) 100 C) 50 D) 90 E) 110 N) none of the above

In an area of the Great Plains, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre). The table shows the number of inches of rainfall and the yield (in bushels per acre). Use for problem #17 and #18. Rainfall (in inches), x 9.8 8.1 12.7 11.8 18.1 9.6 6.3 14.9 15.3 Yield (bushels per acre), y 48.5 44.2 56.8 57 80.4 47.2 29.9 74 76.8 17. Compute the linear correlation coefficient between the two variables above. (Round to thousandths.) 18. Determine whether a linear relation exists. (Show work to justify answer.)
The teacher from Problem 21 also tried a different approach to determining whether changing answers helps or hurts exam grades. In another class, students were told to review their final exams and change any answers they wanted to before turning them in. However, the students had to indicate both the original answer and the changed answer for each question. The teacher graded each exam twice, once using the set of original answers and once with the changes. In the class of n- 22 students, the exam scores improved by an average of MD - 2.5 points with the changed answers. The standard deviation for the difference scores was s = 3.1. Are the data sufficient to conclude that rethinking and changing answers can significantly improve scores? Use a one-tailed test at the .01 level of significance.
