Answer:
8.75 hours
Step-by-step explanation:
We can use ratios to solve. Put the pages over the time and set them equal.
4 pages 7 pages
------------- = ---------------
5 hours x hours
Using cross products
4 * x = 5 *7
4x =35
Divide by 4 on each side
4x/4 = 35/4
x =8.75 hours

Answer:
Step-by-step explanation:
Before you can draw a trend line in your data, you should have a given data at hand. And then draw the trend line or line of best fit.
1. Plot your data in a graphing paper or excel.
2. Make sure that your plotted data has a solid mark to indicate the points in the graph.
3. Divide your data points by labeling x at the center, at the farthest part of your line (left or right diagonally).
4. If you feel that the data are now finely divided, then construct a line base on the x marks you're placing
5. Then you will notice how far or near your date points are by simply looking at the points near the constructed line that you created.
Answer:
99%
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
Sample proportion and same sample size, so what will determine the margin of error is z.
90% confidence level
So , z is the value of Z that has a pvalue of , so .
95% confidence level
So , z is the value of Z that has a pvalue of , so .
99% confidence level
So , z is the value of Z that has a pvalue of , so .
The 99% confidence interval has the largest margin of error.
The size of the next smaller scale wil about 1.464.
The scale factor represents the change between the different sizes. We multiply by it to increase and divide by it to reduce.
1.772 / 1.21 = 1.464
