the probabilities a team wins draws or loses any particular game at 0.6, 0.1, 0.3 respectively. find the probability that the teams wins at least one of its next two games
Add two polynomials
Given two polynomials A and B, write a program that adds the given two polynomials A and B
For term Cix^Pi, if the coefficient of the term Ci is 1, simply print x^Pi instead of 1x^Pi.
If the degree of the polynomial is zero and the constant term is also zero, then just print 0 to represent the polynomial.

kPa and 3.7 kPa.
In the histologic specimen of connective tissue stained with hematoxylin-eosin one can see ramifying cells that are in contact with one another. In general the cells form a network structure the spaces of which contain cord of lymphocytes. One of the students said that that tissue is reticular tissue, another student said that it is bony tissue. Which of the answers is correct?
Use the localised electron model to describe the bonding in hydrogen cyanide and phosgene(cocl2)
. A new machine is being considered to replace the
old machine being used. This new machine was
tested for 10 consecutive hours with the following
output: 119, 122, 118, 122, 120, 124, 126, 125, 125,
and 124. If the average output per hour using the old
machine is 120 units, is the management justified in
stating that the output per hour can be increased with
the new machine? Use a 0.01 level of significance.
- A manufacturer of juices claims that all labeled 1.5 liter bottles contains an average of 1.49 liters of soft drinks. A retailer wishes to test whether the mean amount of juice in a labeled 1.5-liter bottle is not more than 1.49 liters. With 0.05 level of significance.
Q.3A population consists of five numbers 1, 3, 4, 5, and 7. (i) Enumerate all possible samples of size two which can be drawn from the population without replacement. (ii) Calculate the mean and variance of the population. (iii) Show that the mean of the sampling distribution of the sample means is equal to the population mean. (iv) Calculate the standard error of the mean.
