Helllo I am really need help with part g and h because I don't know how to do this problem but every time I submit a problem they give me the wrong parts. i really need help with part g and h can you please give visual representation of circles so I can understand it and can you do it step by step for part g and h. can you label which one is g and which one is h.
We use a wide range of design techniques to increase our comprehension of the code.
Hello. Please create a Python Program for the following question on Probability. Please Only Provide a Screenshot of the Code & result.* If you can do this, I will give you a thumbs up. Thank you!
Instructions in python: Create a compression algorithm that will compress the text "nnneennwnneeeennwwnneeeessseeenneeesswsswwwsssswww" in the parchment piece into a smaller form. The algorithm must include simple instructions of no more than 1 or 2 sentences. It is recommended that you use basic ASCII characters, as the focus here is the algorithm rather than the physical space occupied by the result. Create a copy of this spreadsheet to organize your results and calculate the compression ratios. After working for about 10 minutes, you can access a clue: 2D Map. After another 10 minutes, you can view the 2D Map with Terrain. There are many correct answers to this exercise.
URGENT! What is the simplified expression of ((XY' + XYZ)' + X(Y + XY'))' What is the simplified expression of (A' + B)(A + B) What is the simplified expression of ((A' + C)(B + D'))' What is the simplified expression of (A' + B)(A + B + D)D' What is the simplified expression of AB'C' + AB'C + ABC (step by step) Thank you!
In general, syntax errors are easy to find and easy to correct because the compiler gives indications as to where the errors came from and why they are wrong. Runtime errors are not difficult to find, either, since the reasons and locations for the errors are displayed on the console when the program aborts. Finding logic errors, on the other hand, can be very challenging. In the upcoming chapters, you will learn the techniques of tracing programs and finding logic errors. True or False: Logic errors are often the easiest to find True False Group of answer choices True False
Atomic weights are not provided, but please use rounded-off values to the nearest whole number.(examples: 24.305, use "24"; 107.8682, use "108"; 1.00784, use "1"; 15.999, use "16") Add trailing zeros to complete your answer to the 3rd decimal place, if necessary. (examples: if your answer is "62.7", write it as 62.700; if your answer is "37.12", write it as 37.120if your answer is "123", write it as 123.000) 1. A 500mg oil sample is taken from a conical flask and is dissolved in 50mL distilled alcohol. An indicator is added and is then titrated against 0.112N KOH until a slight pink color appears. It took 17.6mL of the titrant to reach the endpoint. What is the sample’s Acid Value? 2. A fat sample with combination free fatty acids required 8mL and 5mL of standard hydrochloric acid for blank and sample titration, respectively. The normality of the standard hydrochloric acid is 0.93N and the weight of the sample is 3 grams. Calculate the saponification value.
language: python so i still have the same question as in the first photo. the answer from the second photo is correct, however i am also not allowed to use string indexing. is there any way i can still do the substitution cipher in the most most most most most basic way?
I need the answer as soon as possible
