And where did you get 64.9? Is that the velocity or what?
what will i divide by 1/3? And why should I divide it by 1/3?
Could you pleas explain it further? Thanks ;)

the life of electric bulbs has a normal distribution with a mean of 35 months and a standard deviation of 4 months. What should the warranty period be if the company that manufactures these bulbs does not want to replace more than 2% of the bulbs?
This is very helpful. I'm sure this will be reviewed in upcoming classes and understanding this information will help me be a bit ahead of the game. Thank you very much for your help, I'm sure it wasn't an easy feast to type all this information down. Very apprecia...
Hi Im reposting incase my original post doesn't get read. Please see bottom for additional info that I need help getting verified. Many thanks Hi Please help verify my answer to the following question: 0.500g of pure phosphorous was burned in excess pure oxygen to give a p...
Here is wht I did if you can please tell me where I went wrong would be appreciated. resulting compound phosphorous oxide mass = 1.145g # of moles of Phosphorus = 0.500g/30.97g/mol = 0.0161446mol # of grams of combined phosphorus oxide = 1.145g-0.500g (P) = 0.645g of oxygen #o...
Hi Please help verify my answer to the following question: 0.500g of pure phosphorous was burned in excess pure oxygen to give a product that has a mass of 1.145 g. What is the empirical formula of the resulting compound? By the use of a mass spectrometer the molecular mass of...
A ball on the end of a string is revolved at a uniform rate in a vertical circle of radius 72.0 cm, as shown in Fig. 533. If its speed is .4 00 m s and its mass is 0.300 kg, calculate the tension in the string when the ball is (a) at the top of its path, and (b) at the b...
What is the instantaneous velocity of a freely falling object 28 s after it is released from a position of rest? The acceleration of gravity is 9.8 m/s2 . 2)What is its average velocity during this 28 s interval? 3) How far will it fall during this time?
What is the answer?

sorry im real bad at probability. a single die is rolled. find the probabilities: a) P(odd numbers greater than 1) b) P(number less than 5) c) P(the number 3 or 7) i got a) 1/3 b) 1/2 c) 1/6 is that right please help.
hi i did this problem and i just want to know if its right. 3 coins are flipped , find the following probabilities: a) P(2 heads) b) P( at most 2 heads) c) P(no heads) i got a) 1/4 b) .75 c) 5/8
Suppose a single die is rolled, Find: a)P(6, given that an odd number was rolled) b) P(5, given that an odd number was rolled)
This is a statistics question: ***(A) Select a random sample of 30 student from our population (we have a data entry to get the sample from). At the 0.05 level of significance is there evidence that the average travel time is greater than 45 minutes? (B) What assumptions must ...
