Question: Im doing my science homework and says "Practice identifying significant figures. For each of the following, identify the correct number of significant figures and then explain why that is true." Heres the question a. A student records the masses of three unknown samples to be 33.25 g, 43.265 g, and 25.1 g, respectively. What is the correct number of significant figures the student should use when recording the average? HELP!!!!!!!!!!!!!!!!!!!!!!!! Lol THanks Adria

The calculated average = 33.872 g Now, the 25.1 number included in the calculation means it is greater than 25.05 and less than 25.15............it is accurate to three significant places...............ergo, at the very best, the calculated average should be stated to three places...............i.e.........the average = 33.9 g It should be noted that when several items are measured in some way, statistical methodology can be used to further fine tune the number of significant figures.

A digit within a number is a significant figure if: 1.it is non-zero OR 2.it is a zero between 2 significant numbers OR 3.it is a number at the end of a number and to the right of a decimal place. p = m/v,so the problem is 23.523g/17.5L= 1.344p All the digits are significant. Hope this is helpful,IM me if you need a more detailed answer. key:/=division p=rho g=gram L=liter m=mass v=volume Amber

Significant figures is just a way of rounding. Anything that's not a zero is significant. Zeroes between two non-zeroes are significant. And all zeroes to the right of the decimal point and last numbers in the decimal place are significant. 23.523 has 5 significant figures. 17.5 has 3 significant figures. 730064 has 6 significant figures 7300 has 2 significant figures 300740 has 5 significant figures I hope this works for you.

Alright, significant figures are the numbers that tell how accurate data is. In this case, 23.523 is very accurate, because it goes to three decimal places. Significant figures only include nonzero digits of a number, zeroes between those numbers, and final zeros. For example, in the number .005420, the significant figures are 5, 4, 2, and the last 0. The last 0 signifies accuracy to six places When trying to find how many significant figures a result will have, like in this problem, you can only be as accurate as your LEAST accurate data. In this case, your least accurate data is 17.5 liters. So your result will only have three significant figures. I hope this has helped you. If it hasn't, feel free to email me! : )

first of all, calculators do no longer calculate in accordance to important figures, rather they provide what quite a few of my instructors call a "calculator unload." Signifanct figures are designed to enable you recognize the way precise the device the examining got here from is. The greater important digits, the greater precise, and the merely good answer to a situation can haven't any further accuracy than the least precise piece of kit. a million/4.fifty six must be .2--one important parent because of the single and you around down because of the fact the subsequent digit is decrease than 5. 5 has one sig fig, 25 has 2 sig figs, and 456 has 3, the style of important figures is comparable to the style of nonzero digits for numbers without a decimal place. 10342 has 5 sig figs 10000. has 5 sig figs 10000 has in basic terms one important figue because of the fact there is not any decimal factor. The decimal factor shows that the above answer is precisely 10000 while the shortcoming of one shows that the respond is approximately 10000. For greater prepare, attempt googling for prepare questions approximately important figures, or bypass on your textbooks website and look for prepare questions. many of the regulations will make a lot greater experience once you have worked quite a few prepare issues on them. solid success on Tuesday!

Computer science is ALL about Software. We right programes that run on the computer like database programs, games, website applications. The computer engineering people on the other hand actually study in some detail about the actual hardware inside the computer as well. They learn things about eletronics that relates to computers. Things that relate to how computers are made and work. So basically the computer engineering people shall learn about electronics and computer science both combined. The computer science people shall learn about Software and NO hardware. But they shall have a much better understanding of the software world since their focus is only on that and not anything else.

Mr. Matrix is entirely right, though we're a very large embedded software company and we pay the same whether its a CS or CE degree (however, since we're embedded we tend to hire more Comp E majors)
