C.1379. Alex and Burt took their rabbits to a whole salesman to sell them to him at once. Each of them got as many dollars for each of their rabbits as many as the rabbits they each took to him. But, because their rabbits were so beautiful, they each got as many extra dollars for their rabbits from the salesman as many as the rabbits they each sold him. This way Alex received $202 more than Burt. How many rabbits did they each sell to the salesman?

6.Hi, i have a task where i need to calculate the 3 months weighted moving average for May 2021, The ...

eight should be based on the count of sales for the previous period, the actual period and the next period.
In the excel you can see the housing data:
period(month)
sum of prices(K)
sum of the asses value(T)
K/T value (sum of prices/sum of the asses value)
The answer i'm looking for is that for May 2021 the price development in percentage should be 9.5% compared to three month back. To calculate the price development you just divide the K/T value, for example:
period 1 K/T value = 1.4
period 4 K/T value = 1.9
Price development = (1.9/1.4)-1 = 35.7% increase.
So i want to see 9.5% increase on May 2021 compared to 3 months earlier.

hensive Cancer Network (NCCN) guideline panels are allowed to receive up to $20,000 per year in payments from a single pharmaceutical or medical device company or $50,000 in the aggregate per year. Specifically, the NCCN website states the following: "If an NCCN Guidelines Panel Member or prospective Member or an NCCN Guidelines Steering Committee Member or prospective Member has an equal to or greater than $20,000 conflicting interest from at least one single external entity, including the sum of income and equity holdings from said entity, or if their aggregate conflicting interest from all external entities is equal to or greater than $50,000 per year, the Member or proposed appointee will be deemed ineligible for continued service or for appointment."
Some experts claim that these thresholds are way too high, and that NCCN guideline panelists should only be doctors who don't receive any money or funding from pharma whatsoever. But Dr Robert Carlson, the CEO of NCCN, defends the organization's current policy saying that tightening the rules would lead to exclusion of best experts in oncology and ultimately affect the quality of the guidelines.
Write a research paper that examines this question: Should NCCN panelists be allowed to receive any money or funding from pharmaceutical or/and medical device companies while serving on the panels? Support your stance on the issue with solid evidence from eight or more reputable sources and use APA citation style, 7th edition, for the assignment. Make sure your paper includes a title page on page 1 and an abstract on page 2, and is formatted in accordance with APA. Finally, please include an "Opposition" section in your paper where you will acknowledge and explain the views of people who would disagree with you.

year will increase the amount charged on its credit card. The bank makes this offer to a random sample of 225 of its credit card customers. It then compares how much these customers charge this year with the amount that they charged last year. The mean increase in the sample is $560, with sum of squares SS= $1,417,250. Is there significant evidence at 1% level that the mean amount charged increases under the no-fee offer?
