z score formula probability

Our object is to minimise the product xy. Let Z = xy. We have to maximise Z..

The number which tells us how many times a particular data appears is called the frequency. For example, 2 marks have been scored by five students which means marks 2 occurs five times. Therefore, the frequency of score 2 is five. Similarly, the frequency of marks 5 is three..

Since the objective function is Z = ax + by, draw a dotted line for the equation ax + by = k, where k is any constant. Sometimes it is convenient to take k as the LCM of a and ..

Question: Find the mode of : 43, 42, 44, 40, 48, 45, 40, 40 Answer: 40, 40, 40, 42, 43, 44, 45, 48 Since 40 is the most repeated score, Mode = 4..

Question: The median of prime numbers between 51 and 80. Answer: 53, 59, 61, 67, 71, 73, 79 Median = Middle-most score Median = 6..

Statistics - The collection of data, its classification, tabulation and study is called Statistics. Consider the marks obtained (out of 20) in the inter-school talent contest by the students of a school.

Identify the corner point at which the value of the objective function is maximum (or minimum depending on the LPP) The co-ordinates of this vertex is the optimal solution and the value of Z is the optimal val..

Question 1 - Question: Find the median of : 83, 37, 70, 29, 45, 63, 41, 70, 30, 54 Answer: 29, 30, 37, 41, 45, 54, 63, 70, 70, 83 Median = Middle-most score Median = 49..

The mathematical models which tells to optimise (minimize or maximise) the objective function Z subject to certain condition on the variables is called a Linear programming problem (LPP)...

The mathematical models which tells to optimise (minimize or maximise) the objective function Z subject to certain condition on the variables is called a Linear programming problem (LPP). During World War II, the military managements in the U.K and the USA engaged a team of s..
