Arithmetic mean

https://mathspace.co/ website enabled a practical element in regards to algebra strengths and weaknesses. The first objective to the question was to break down each part of the equation and then see how it relates to the answers. Multiplying ‘n’ by itself represented ‘n x 2’ which in algebra is ‘n2’, then it was simply continuing the equation by dividing that number by two as a way to half it and then subtracting ten. Once I had done this I was comfortable with the answer. ACARA (n.d.) identifies that in Year 7 students should be confident in the concept of variables being able to represent numbers using letters. This highlights the importance of gaining an understanding early, as all that is needed in a question like this is to recognise the arithmetic needed and how they work in an algebra context. Another way of solving the problem was not apparent other than working from back to front or the process of…

Barbara, as I have looked and pondered the concerns and emails given to me, I have come up with some key facts that will solve your problem. Prior to beginning I would like to address that what you are facing is not just an “accountant” problem but also a teamwork problem. What I mean by that is, you cant expect your company to progress or succeed when half of your workers are scared of working with their coworkers and the other half don’t care about their fellow team members in order to help…

other three populations( low interest manipulation or losing candidates), a one – way between subjects ANOVA was conducted to compare four neighborhoods in Frostburg, MD. The test consist of four independent levels. Population 1: Winners with high interest neighborhoods. Population 2: Winners with low interest neighborhoods. Population 3: Losers with high interest neighborhoods. Population 4: Losers with low interest neighborhoods. All of the calculations for this test were done by hand. I…

function in Microsoft excel we were able to calculate our standard deviation which was 2.22. With the expected value being two this was a good result because it is very similar. The measured results of my data were 7.44(average) and 2.22(sigma) which together do agrees with the theoretical results of 8 because it is within that range. Next we calculated the normalized results and found out that the coins we used were fair. They had and average of .47 per penny and a sigma of .14. These values…

for the survey and grade level data collection has clarified how the staff and leadership should aspire to be a second generation school. According to Lexotte (1991), “second genreation correlates represent a developmental step beyond the first and, will move the school even closer to the the mission of Learning for All” (p. 1). Viable conclusions based on the mean scores from the Effective School…

Basically, there should be a noticeable and systematic increase in the standard deviation based on an increase in size of the target circle, while the matching circle mean should stay close to the actual physical size of the target circle. In other words, it should be possible to see a progressive and regular increase in the standard deviation from a 10-, to a 30-, to a 50-pixel circle; and alternately, a systematic decrease in the standard deviation when moving in the opposite direction from…

The writing style is generally appropriate to the assignment, fresh (interesting to read), accurate (no far-fetched, unsupported comments), precise (say what you mean), and concise (not wordy). The writing style is appropriate in places, but elsewhere language is vague and imprecise. Writing style interferes with the development and clarity of the main points. Writing style makes it virtually impossible to understand the writer’s…

hypotheses based on demographics by studying the number of correct responses and mean reaction time by observing pre-calculated students t-test. This particular assessment compared the students’ response times and mean correct responses in picture-recognition tests and facial-recognition tests. The null hypothesis for this case is that there is no difference in the mean response time or average number of correct responses…

impulsiveness should reflect how quickly they respond to the stimuli in each given task. Studies in the past have linked older adults to have a slower reaction time in comparison with those younger than them. This research statistic correlates with our study and helps support that the younger the participant is then they will be more prone to take more risks and be more impulsive. The main focus in this research though, is will age play a major factor in risk-taking and impulsiveness? The…
