Calculate the parameters of your individual assessment: Let M be the maximum of all digits of your student ID and A is the average of all digits of your student ID. For example, if your AUM student ID is 34106, then M-6, and AD (3+4+1+0+6)/5=14/5=2.8 Question 2: Normal Distribution ( In an orange plantation the weight of the orange fruit is Normally distributed with mean of 40 A grams and standard deviation of M*3 grams. Answer the following questions: a) What is the probability that a randomly selected orange fruit will weight mor than 110 grams? b) What is the probability that a randomly selected orange fruit will weight less than 180 grams? c) What is the top weight of the fruits that only 20% of the oranges will exceed

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
