Explanation & Answer
Felipe runs 25 laps in 34 minutes
He has to run 30 laps
25 laps =34 minutes
1 lap =34/25 minute
30 laps =34/25*30=34*6/5=34*1.2=40.8 minutes
He will take 40.8 minutes

Part 1 focuses on percentiles and statistical measures of average You decide to invest in stock in a particular type of company and set the guideline that you will only buy stock in companies that are ranked in the 80th percentile or above in terms of dividends paid in the previous year. You are looking at a company that ranked 20 of 150 companies that paid dividends in 2019.a. Will this company qualify for your portfolio?b. If you had the data on the total dividends paid by each of the 150 companies, which measure of average would be the most meaningful – mean, median, midrange, or mode? ExplainPart 2 focuses on counting techniques and probability.A student - faculty government committee of 4 people is to be formed from 20 student volunteers and 5 faculty volunteers.a. If one person from the group of volunteers is chosen at random to draw the names out of a hat, what is the probability that the person drawing the names is a student?b. How many ways can the committee of four be formed if there are no restrictions on composition.c. How many ways can two of the students be chosen?d. How many ways can 2 faculty be chosen?e. What is the probability that the random selection of the four- person committee will result in two students and two faculty Be sure that you show all of your work to reach your answer.

Grossmont College David Merrell Rats Used for Treatment Groups Discussion
Context
A high school student named David Merrell did an experiment to examine if music affects the ability of rats to run a maze. The explanatory variable was exposure to music. He had three treatment groups: one group listened to heavy metal music by the group Anthrax. A second group listened to Mozart. The third group never heard music. This last group is the control group.
The response variable was the average time (in seconds) to complete three runs. Every week the rats ran the maze three times. Merrell recorded each rat's average time for the week.
Direct controls of potential confounding variables:
Merrell trained all of the rats to run the same maze.
He gave all mice the same amount of food and light.
All mice had the same approximate age and weights.
During the treatment phase, the rats were exposed to the treatment for the same amount of time, e.g. rats heard music at 70 decibels for 10 hours a day for a month.
Results:
By the end of the month the Anthrax group was much slower at running the maze. The Mozart group was much faster. The dotplots below show average run times for the first and last week of the experiment. Each dot represents one rat. The X-value is the rat’s average run time for the week. (Each rat ran the maze 3 times each week.) The blue line is the mean run time for each treatment group.
If you are curious, here is a video of Merrell explaining his experiment.

Prompt
Merrell claims that he randomly assigned rats to treatment groups. Does the data shown in the dotplots above support his claim? Why or why not?

MAT3172CBE G&B Consulting Construct and Analyze a Game Tree Paper
InstructionsA telecom company is considering upgrading their infrastructure in your city and they have hired G&B Consulting. The telecom company would be willing to invest in upgraded lines that offer higher speeds and bandwidth, but it is costly to do so and they are afraid they might make the investment but not have customers willing to upgrade their services which would be needed to recoup their profits. The alternative would be to keep the old infrastructure, but there are already a high amount of service complaints from the customer base. The telecom company needs to determine if investing in the improved service will pay off for them by having a sufficient amount of customers buy the upgraded service. You have been tasked with helping them determine their optimum strategy.What to SubmitTo complete this assignment, you must first download the word document (attached).Your step-by-step breakdown of the problems, INCLUDING EXPLANATIONS, should be present in your POWERPOINT you create.
