Homework Help

Hey I am really struggling with this sort of question. I have changed it because I want to do my homework one myself. How would I do this, I know I have to make 5 states and then work out where the numbers go but I have idea. Has anyone got any idea's or tips? The State Transition Table and Output Table for a Finite-State Transducer, with start state S0, are as follows:- State S0 S1 S2 S3 S4 Inputs 1 S4 S3 S4 S1 S1 ...........0 S3 S2 S2 S2 S3 S0 S1 S2 S3 S4 Inputs 1 1 0 0 0 0 ...........0 0 1…

If the mean mercury concentration in fish caught in a particular lake is below 0.5ppm then the state of florida would class that lake as acceptable. On the basis of the data provided in the case study how should the state classify each lake ? so there are basically two lakes, East Lake and Lake Iamonia. East lake mean= 1.1765 sd=0.2802 Lake Iamonia mean= 0.598 sd= 0.2836 formula used = t= mean-value(0.5)/s/square root of n The t-value for the first lake is 15.27, and the total population is 40(fishes) so the answer given by my teacher is t39(0.025) = 3.307< 15.27. So hes looked at the 99.9 % column in the t-table. For the next lake, hes looked at …

Hi everyone. I'm new here. I need a Borosilicate measuring glass for a project but don't know where to get one. Can I get one from a store or do I have to buy online?

This is basically what I am given. I need to use all those variables as a function of the minimum height: I need to figure out what the minimum height of the bridge should be for the person to just barely touch the water, taking into account gravity, the mass of the person, etc. (all listed in the image). I need to take into account the Law of Conservation of Energy (LCE). This is what I came up with, but I'm not sure if it's right: h = (mv²+kx² / 2mg) + (l+L) *the lower case L (l) is supposed to be handwritten, like it appears in the image. Thanks for any help! Edit: btw, this is how I got the equation: mgh = mv²/2 + kx²/2 (by LCE) but h should actually…

Hi, I have a question about normal distribution. A large population of animals were found to possess a mean length of 18cm with a standard deviation of 2cm. What percentage of animals are longer than 20cm? so i know you use the formula to standardize the Z. But then from the cumulative table, how do we know which column to look for? and then the next question is, What percentage of animals should be between 15cm and 20.5 cm in length? in the formula, how do you put both figures 15 and 20.5 ? and then the last question is What length should enclose the shortest 60% of the animals ? please help Also does anyone know a good website for statistics ?

This is a really weird question...in my opinion... We are told to bake a cake, and we have to use a sulfur solution (sulfur + water ONLY). We must add 100g / L of the solution. (Yes, it's grams, not ml.) How much of the solution should we add to get that amount? From what I know, concentration = mol / L. We know concentration, and we have to find the volume. What I'm not sure is how to calculate for the mol (we're not given a mass) and how to convert the g to ml? I'm not sure if mass is necessary. Or, if we need one, we use a number found in society and indicate why we use it? I'm not sure if I even approached this question correctly...if anyone could help…

Hi , Can anyone help me with drawing a scale plan ? I basically have a free hand sketch of a room, (crime scene) and measured dimensions in cm on it. It contains a window, cupboard, walls, and a piece of evidence in middle of the room with measurements, the position of the evidence is shown by measuring two points from a baseline of the room(triangulation method) But I dont know how to make a scale for it I looked on the internet but cannot find anything useful. Has anyone done something similar or same for thier forensic module? Please help

HI guys. I have a problem with my assignment like: Hexadecimal numbers are made using the sixteen digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. For a four digit number, the most significant digit is restricted to the digits 7 to C and the least significant digit is restricted to the digits 9 to F.How many numbers are there? Because i am an overseas student, so it is very difficult for me to understand "the most significant digit is restricted to the digits 7 to C and the least significant digit is restricted to the digits 9 to F", can you explain to me,please? Or can you give some examples with this pattern, please? Thank you very much.

Hi im finding it hard to calculate a formula. Can anyone please help me ? t=13.94-15.55/squareroot of 1.8410(1/14+1/15) the answer to this is -3.19 but i keep getting diffrent answers because im confused on how to work out the 1/14+1/15 bit. which step are you supposed to do first ? thanks

Hello, Though the questions that I post in this Homework help section are actually not related to my homework but appear in my 9th STD physics text book with the label "Think It Over", I feel it is appropriate to post them here, because even after much thinking I have not been able to find right explanation. The question is- "The aluminium wires used in the transmission of electric current are not insulated. Why?" Thanks.

Hi Anyone good with statistics ? I just want to confirm something, not asking for answers. The standard error of the mean SEM, is it the square root of standard deviation or is it standard deviation divided by the square root of n, the sample number. Please can someone clarify, i have a test and I dont want to do the wrong thing.

Recall that the specific heat of water is 1 cal per gram per degree celsius, and the density of water is 1 gram per cubic centimeter. For this problem, use these values for water, although ocean water is not exactly the same. Assume also: The tropical Atlantic is 3000 km wide and 5000 km from north to south. Finally, assume that the average ocean surface heating is down to a meter depth. 1. How much extra energy is stored in the tropical Atlantic with one degree celsius of temperature increase? 2. How does this value compare with the total annual energy usage in America if we assume that number is a wopping 25,200 quadrillion calories (2.52 x …

Hi all, I really need help on this. I recently did a experiment where i ran a gel electrophoresis, and then got a printed copy of the gel image, I had 7 lanes/samples but unfortunately it did not come out all well due to problems with the gel. lane 1 had 1kbp ladder lane 2 had undigested plasmid lane 3 had Ndel digested plasmid lane 4 had hindIII digested plasmid lane 5 had Ndel and hindIII digested plasmid lane 6 had PCR product lane 7 had 100bp ladder So i can only see the first lane i think and last lane/band patterns, but not all of them. How would I prepare standard curves and use them to calculate the sizes of uncut plasmid, single digest…

I have to design a lab with an organism is a pollutant. I need 5 increments and 3 responding variables. There are three days to do the lab, with 1 hour or so a day to run experiments. For the rest of the time the organism has to live in a closed shoebox. I was thinking of using some type of water plant, like algae, since water pollutants have faster effects than airborne or soil. For the pollutant, maybe cadmium? Or Ni, or Pb. I know those are major sources of water pollutants, though I'm not sure if they'll have much effect Does anyone have ideas of what increments can be used and what can be observed? I can only think of growth, and I;m not even sure if tha…

Ok so those of you familiar with the edexcel GCSE exam board, we have to do these assessed practicals, and the one I'm going to do in biology is apparently one that has never worked, in all the years that it has been around apparently even the exam board couldn't make it work when they went on a conference in Malaysia. The experiment is as described below: The aim of the experiment is to find out how temperature affects aerobic respiration. So the method in which we are going to test this will be using mealworms (the exam boards idea). Basically we are going to take the mealworms and place them into different beakers. So basically I think it would be about 5 meal wor…

Hi, I am currently working on this project: http://www.sciencebuddies.org/science-fair-projects/project_ideas/Geo_p022.shtml I have plotted the seismic waves of an earthquake and drawn the time travel curves, but I cannot figure out the last two steps: - At what distance from the quake in degrees does the primary S-wave no longer appear? - What is the maximum distance at which the primary S-wave appears? I am doing this for only one earthquake, and I am running out of time. I don't get how to this, but if someone would provide an example or an explanation as to how this works, that would be great!
