It’s review question, I need this as soon as possible. Thank you 3) For thè diferential equation: (a) The point zo =-1 is an ordinary point. Compute the recursion formula for the coefficients of the power series solution centered at zo- -1 and use it to compute the first three nonzero terms of the power series when -1)-s and v(-1)-0....
The partial probability distribution of X, the number of defective tires on a randomly selected automobile checked at a certain inspection station, is given below. If one of those automobiled is equally likely to have either 2 or 3 defective tires, what is P[(X = 2) U (X = 4)] = P(2 U 4)? x 0 1 2 3 4...

If tires are randomly selected one at a time and tested.a) What is the probability that the first non defective tire will be found on the second trial?b) What is the probability that the third non-defective tire will be found (i) on the fifth trial?(ii) on or before the...
When 2 defective items are extracted one by one in a partition consisting of 6 products and checked, Let X be the number of tests before finding the last defective item find the probability distribution of X. Draw a graph of the distribution function F (x) of X · Calculate the mean μ and standard deviation σ of X. please...
What is the number of hours it will take an automobile going forty-five miles per hour to catch up with an automobile moving at thirty miles per hour if the slower automobile starts one hour before the faster automobile?
Assume that Acme Tires sells their high performance tires for $180 each and their all weather tires for $135 each. Further assume that the cost of producing a high performance tire is $150 and the cost of producing an all weather tire is $120. Finally, assume that if a tire does not last 40,000 miles, Acme tires will replace it...
Hebble Tires produces three types of tires. In their manufacture, the tires are processed on two machines, a molder and a capper. The time (in hours) required on each machine and the income (wholesale selling price less costs, including labor at the regular pay rate) per unit made of each type of tire are: Machine Time (hr) TypeMolderCapper Income($) 45...
2. Bicycle tires use a different nomenclature from that for automobile tires. For instance, a 26 x 13 tire has an outside diameter of 26 inches. But, as with an auto tire, the 1 does indicate that the (largest) cross-sectional width of the tire is 1 inches. The cross-section of a bicycle tire is very nearly circular. Using a radius...

A box contains 30 parts, of which 5 are defective and 25 are non-defective. If two parts are selected without replacement a.Construct a tree diagram with a listing of all the outcomes and probabilities: b.P(exactly one non-defective part) include both fractional and decimal answers. c.P( at least one defective) d.P( neither is defective)
It is also known that 3% of the items produced by machine A are defective, as are 2% of the items produced by machine B and 1% of the items from machine C. If a randomly selected item from the factory's output is found to be defective, what is the probability that it was produced by machine B? Also, if...
The Chemco Company manufactures car tires that last distances 8. The Chemco Company manufactures car tires that last distances having a normal distribution with a mean of 35,000 miles and a standard deviation of 4275 miles. If the manufacturer wants to guarantee the tires so that only 3% will be replaced because of failure before the guaranteed number of miles,...

2. A groups of developmental psychologists wanted to examine under what conditions children of 24 month of age can generate the most number of words. They randomly selected 45 children and randomly assigned them to three different conditions. Then they measured the number of words the children uttered in the three conditions. Specify the null hypothesis and test it at...
