Finally we got all our number and determine the slope, and the intercept in order to find out the forecast for the next

Trend Analysis is attempting to spot a pattern in information that is collected. Trend analysis is mostly used to predict future events, although another good use is to review and estimate the situation of past events.

The average rate of change is an average slope from the initial point to the final point. We would have to use A(x)=f(x)-f(a) divided by x-a to find the average rate of change. Sometimes we would want to know what the average rate of change is in the middle of the graph. The average rate of change is used in page 10, “How many more people?.” The concept of slope comes from the idea of a constant rate of change. To find the slope, you have to calculate y1-y2 divided by x1-x2. Slope is often denoted by the letter “m” which means that m+ equals the slope. Its problem is being used in page 21, “Rates, Graph, Slopes, and Equations.” Y=mx+b is the equation of the line that you can find using the two points. Variable “m” is the slope and “b” is the y-intercept.

Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

This paper comprises an appreciation of data representation, its visualization, an outline description of behavior, plus an indication of the use of the equation in engineering.

Solving systems of equations requires prior knowledge of equations. Students must be familiar with how to interchange equations from standard form to slope intercept form. In standard form, which is AX=By=C, the student must recall prior knowledge of how to maneuver the variables in order to isolate the (y) variable one side of the equal sign. Once the student has the equation in slope intercept form , he/she will be able to place the equation in the calculator to graph in order to show which points lie on the (x) and (y)

2. Write a program to calculate and display the y intercept of a point lying on a straight line

axis be parallel to the ground and the positive y axis point upward. In the time interval from

Trend analysis, common-size financial statements, and ratios are presented for the Brody Corporation in Figure 5.4. Assume that you are auditing Brody 's financial statements for the year ended 12/31/X8. You have performed tests of controls over the recording of gross sales and believe that the system is operating effectively and that 7 percent represents an accurate estimate of the increase in gross sales for 20X8 over the amount for 20X7. You should also assume that the financial statements for 20X6 and 20X7 are not misstated.

What formula or function does he put in Column F that will show the total expenses for each day?

This regression equation can be graphed as follows assuming β0 as the intercept and β1 as the slope:

Hence in the above computation, I had taken an assumption that the data provided on the top line is annual figures.

The trendline, known as the line of best fit or the least squares regression line, shows the linear equation which best explains the sums up the data’s trend. The formula on the right is the formula of the line of best fit.

By focusing on the different segments economists can determine if underlying trends support the headline numbers in total or have possibly skewed the overall numbers.

Marriott use trend analysis that allows them to make better business decisions. An example of trend analysis would be the monitoring of market conditions on a local and regional basis that will affect demand in a positive or negative way. For example a weekend concert will increase demand to the area, which in turn will show an increase in rate to ensure maximum revenue is achieved during this period,
