Tide Modelling

18. Draw a best-fit line for the Tonga Trench data. A best fit line is a smooth line that shows the trend of the data; the line does not have to pass through the data points.

3.) I said the model should taste 10 cups of coffee. Fisher said the tea lady should taste 8 cups of tea. Fisher's answer to this question was that the "tea lady" should taste 8 cups of coffee because there are 70 possible outcomes of the order in which they are presented for her tasting. Fisher said "There are 70 ways of choosing a group of 4 objects out of 8… namely that if we were to choose the 4 objects in succession we should have successively 8,7,6,5 objects to choose from, and could make our succession of choices 8 times 7 times 6 times 5 or in 1680 ways." My answere was not exactly the same as fishers but it was quite similar. He chose 8 as the amount of cups served, but I chose 10. We both did choose a reasonable amount of cups that should be served and we both have a fair amount of possible outcomes in which the coffee/ tea could be

Introduction: Today scientists put acquired data into a form of a graph. This said graph is designed to help make predictions and furthermore, study and understand the experiment and its contents at hand. The Graphing and Estimating lab involves just that. The lab is designed to collect data from several tests involving burn time of a candle.

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

The slope of the linear fit of the data is 1.0049. What this tells me about the water is that it is increasing at a close to constant rate – while my results were not completely accurate because the slope of the line was not one it was fairly close to the target

At first, I was confused with this problem and did not know what to do. For this problem, I used only one problem and it was what helped me solve it. With my table group (Derick & I), we did a simulation. We first drew out a large map with the points that every ship should reach at the start of every month. Then we kept feeding in the blocks (which we used to act as ships) and did the simulation. Using this strategy, we were able to find the solution.

For a boat with a displacement of d pounds and a sail area of A square feet S is determined by the function S = 16Ad-2/3. a) Find S to the nearest tenth for the Tartan 4100, which has a sail area of 810 square feet and a displacement of 23,245 pounds. b) Write d in terms of A and S .

3) What do the rate of change values you just calculated represent? Why are some positive and some negative?

Therefore, during experiment (2:39 pm first in and 4:01 pm last out), we had second low tide after we put meter stick on 2B but before 3A. Then, the graph shows that the tide started to rise slowly during rest of period. 1B (2:40 - 4:01 pm), 3A (3:01-3:52 pm) and 4B(3:13-3:38 pm) have positive

9) Since you are plotting displacement on the y-axis and time on the x-axis, this is an example

The scatter plot of Credit balance ($) versus Size show that the slope of the „best fit‟ line is upward (positive);this indicates that Credit balance varies directly with Size. As Size increases, Credit Balance also increases vice versa. Correct

The average time to reach the port was averaged for each option 1 from the data given

4. View of ocean. The presence or absence of an ocean view is recorded for each unit and specified with a dummy variable (1 if the unit possessed an ocean view and 0 if not). Note that units not possessing an ocean view would face the parking lot.

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

Step 10: Draw a scatter plot of T2 on the Y-axis against L on the X-axis.
