6. A sample data set D is provided online in the file Spacecraft.mat. Use the load com-
mand to load this data into your workspace. A matrix D contains data on several experimen-
tal spacecraft engines. The matrix is organized in pairs of rows. Each pair of rows contains
data measured during tests of the engines. For each pair of rows, the odd numbered row
contains several measurements of the total energy used by the engine and the even num-
bered row contains the corresponding total kinetic energy imparted to the spacecraft.
Recalling the equation for energy efficiency, En = n E₁ we see that the efficiency of the
engine is the slope of the line if the kinetic energy of the spacecraft (the output energy, E₁)
is plotted versus energy input to the engine (E₁).

Welcome Oscar Hernandez ENGI 1331 (24467, 24471) Zelisko
For each data set in matrix D:
(a) Determine the efficiency of the engine represented by each data set.
(b) For each data set with an efficiency of at least 0.8 (80%), plot the data (all data sets on
the same graph) represented by red diamonds. Add a solid red trendline to each such
data set, including a trendline equation.
(c) For each data set with an efficiency of at least 0.5 (50%) but less than 0.8 (80%), plot
the data (all data sets on the same graph) represented by blue circles. Add a dotted
blue trendline to each such data set, including a trendline equation.
(d) For each data set with an efficiency less than 0.5 (50%), plot the data (all data sets on
the same graph) represented by black X's. These low-efficiency data sets will NOT have
a trendline or equation added.
(e) The trendline equations should be in the form E# = n E#₁ where # is the number of
the dataset (half of the even-numbered row of the data set).

(f) The trendline equations should be positioned immediately to the right of the largest
(rightmost) data point of the corresponding data set.
Note that you SHOULD NOT figure out the efficiencies and hard-code the line types, etc.
Your program must do this automatically so it will work for any set of data without user
intervention.
The graph should be properly labeled and formatted, but the colors and types of both
the lines and data markers will not follow the standard proper plot rules since they are
specified in the problem.
You may assume the largest value of E₁ is 12 and the largest value of Eo is 10.
For the sample dataset provided, your graph should be similar to the following.

Is it free to get my assignment evaluated?

Yes. No hidden fees. You pay for the solution only, and all the explanations about how to run it are included in the price. It takes up to 24 hours to get a quote from an expert. In some cases, we can help you faster if an expert is available, but you should always order in advance to avoid the risks. You can place a new order here.

How much does it cost?

The cost depends on many factors: how far away the deadline is, how hard/big the task is, if it is code only or a report, etc. We try to give rough estimates here, but it is just for orientation (in USD):

Regular homework | $20 - $150 |

Advanced homework | $100 - $300 |

Group project or a report | $200 - $500 |

Mid-term or final project | $200 - $800 |

Live exam help | $100 - $300 |

Full thesis | $1000 - $3000 |

How do I pay?

Credit card or PayPal. You don't need to create/have a Payal account in order to pay by a credit card. Paypal offers you "buyer's protection" in case of any issues.

Why do I need to pay in advance?

We have no way to request money after we send you the solution. PayPal works as a middleman, which protects you in case of any disputes, so you should feel safe paying using PayPal.

Do you do essays?

No, unless it is a data analysis essay or report. This is because essays are very personal and it is easy to see when they are written by another person. This is not the case with math and programming.

Why there are no discounts?

It is because we don't want to lie - in such services no discount can be set in advance because we set the price knowing that there is a discount. For example, if we wanted to ask for $100, we could tell that the price is $200 and because you are special, we can do a 50% discount. It is the way all scam websites operate. We set honest prices instead, so there is no need for fake discounts.

Do you do live tutoring?

No, it is simply not how we operate. How often do you meet a great programmer who is also a great speaker? Rarely. It is why we encourage our experts to write down explanations instead of having a live call. It is often enough to get you started - analyzing and running the solutions is a big part of learning.

What happens if I am not satisfied with the solution?

Another expert will review the task, and if your claim is reasonable - we refund the payment and often block the freelancer from our platform. Because we are so harsh with our experts - the ones working with us are very trustworthy to deliver high-quality assignment solutions on time.
