Exercise 2 The scores on the entrance exam at an exclusive university in Bellevue are normally distributed with a mean score of 150 and a standard deviation equals to 40. Sketch the distribution of the scores (you can draw it manually), find the probability and show your calculations, that a randomly selected applicant has a score: a. Under 100 b. Under 50 c. Over 180 d. Between 110 and 200 e. Within 1.5 standard deviations of the mean f. What...

Question 2 please
Exercise 1. Define an operation on Z by a b= a - b. Determine ife is associative or commutative. Find a right identity. Is there a left identity? What about inverses? Exercise 2. Write a multiplication table for the set A = {a,b,c,d,e} such that e is an identity element, the product is defined for all elements and each element has an inverse, but the product is NOT associative. Show by example that it is not associative....

Question 2. In this exercise, you will show that Z[V-5] is not a U.F.D. (but it is an I.D., as you proved last lecture!) You will learn a common trick for reasoning about irreducibility and primality in a ring - with the help of special multiplicative functions to Z>. (i) First, calculate the units in Z[V-5] [Hint: calculate inverses first, assuming you can divide ("work- ing in Q[V-5]", and then see which ones actually lie in Z[V-5]] (ii) Next, we...

Exercise 5: A sculptor can sell his newly created masterpieces to an art dealer for resale at next weekend's art show. The offer from the dealer is for $ 12,000 for all the sculptures and is good for only a week. The sculpture could pursue selling the sculptures himself on internet, especially on a particular auction site for artists. If the bidding is strong (with a probability of 0.60), then the sculptor can receive up to $ 18,000 for all...

Exercise 2: Map Symbols (7 marks) 1. On the blank map below of a region with no hills or valleys, draw the appropriate strike and dip symbol next to the appropriate point. To do this, you must use a protractor and measure the angle between the north direction the side edge of the map) and the strike angle. Then, look at the direction of dip so that you put the dip tick on the correct side of the strike symbol....

EXERCISE 1: DATA INTERPRETATION Bone mineral density (BMD) measures the amount of crucial minerals, particularly calcium, in the bones of the human body. levels of BMD indicate a condition known as osteopenia, which can lead to osteoporosis. This disorder leads to a higher risk bone fractures. Examine the data presented in Table 4 showing average BMD measurements of people at different ages and answer the associated questions. What patterns do you observe based on the information in Table 4. Table...
