QUESTION 3. There have been 5 quizzes so far in Michael's Molecular Biochemistry course, and Michaelhas scored 50, 48, 63, 76 and 41. He's not a great student. But there will be 3 more quizzes, and ifMichael averages 67 for all the quizzes, the professor will give him a C and he will be able to enroll inAdvanced Molecular Biochemistry next semester.What does Michael need to average on the last 3 quizzes to get the C ?

We know that the average of the given set of numbers is equal to the ratio of the sum of the numbers…

Show full solution. To inspect the quality of the screens for mobile phones produced by Company X, two separate inspection devices are used to test the screens for defects. Basically, a specific screen is tested once using the two inspection devices. Device 1 can detect the presence of defects 99.3% of the time, whereas Device 2 can detect defects 99.7% of the time. Assume that the 2 devices are operating independently from each other. One day, four defective screens were sent for inspection. Let X represent the number of screens that will be correctly tagged as defective by Device 1, while Y represents the number of screens that will be correctly tagged as defective by Device 2. Determine the following:a.) fXY(x,y)b.) fX (x)c.) E(X)
MAKE SURE YOU SELECT 2 ANSWERS FOR THIS QUESTION - Type of test and hypothesis. Professor Ratzo wonders if rats will run a maze faster for some kinds of foods than for others. He randomly assigns 30 rats to one of three conditions, 10 rats to each condition. Group 1 gets buttered bread at the end of the maze, Group 2 gets cheddar cheese, and Group 3 gets honey- glazed ham. The number of seconds each rat took to run the maze is recorded. The hypothesis is that type of food makes a difference in rat running time. Choose the type of test you should use to test this hypothesis? Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).

9. This year, Mary's troop sold 9,462 boxes of greeting cards. Each of the 6 members sold the same number of boxes. This year, each troop member sold 125 more boxes than they sold last year. How many boxes of greeting cards did each troop member sell last year? 10 C 1,577 boxes D 1,702 boxes A 750 boxes B 1,452 boxes
4. In the beginning of the year 1990, there were three times as many Chinese as Europeans. The Chinese population increases every year by 2%, while the European population decreases each year by 0.5%. When will there be four times as many Chinese as Europeans?
A student wants an A in his Math class, so must finish the semester with a 90 average. So far, he has taken 4 tests ( 90, 85, 92, 80) and taken the midterm (93). The midterm is worth 2 test grades, and the final is worth 3 test grades. What score must he achieve on the final to get an A? The grade is made up of 9 parts, so to achieve an average of at least 90, a student would need 810 (9x9) points. Add the 4 test grades and the midterm grade twice giving 6 parts. Subtract this number from 810 to find the points needed for the last 3 parts which represents the grade earned on the Final. Divide that number by 3 and round up to the next whole number to find the lowest Final grade needed to get an A for the course. The lowest Final test grade needed for an A is

You are coaching a high school basketball team and you realize the importance of free throw shooting, the skill to make foul shots. The question is: how much practice time should be spent in shooting free throws. Thus, you divide your team of 21 players into three groups and practice according to the following schedule that produces thee results after one month. The results are the number of free throws made in 50 attempts. 10 minutes per practice session 15 minutes 20 minutes 25 26 34 30 32 33 31 30 32 33 32…
14. A student has taken three math tests so far this semester. His scores for the first three tests were 75,79, and 83. Suppose this test scores continue to improve at the same rate, What will be his grade on the sixth (and final) test? What will be his total score for all six tests?
An aerosolized vaccine for measles was developed in Mexico and has been used on 44 million children since 1980. Aerosolized vaccines have the advantages of being able to be administered by people without clinical training and do not cause injection‐associated infections. The percentage of children developing an immune response to measles after receiving the subcutaneous injection of the vaccine is 95%,95%, and for those receiving the aerosolized vaccine, it is 85%85% . There are 2020 children to be vaccinated for measles using the aerosolized vaccine in a small rural village in India. We are going to count the number who developed an immune response to measles after the vaccination. (b) What is the probability that at least one child does not develop an immune response to measles after receiving the aerosolized vaccine? (Enter your answer as a proportion rounded to four decimal places.)
