- Prove or disprove that AB=AC implies B=C.A glazier buys his glass from four different manufacturers - Clearglass (10%),Strongpane (25%), Mirrorglass (30%) and Reflection (35%). In the past, the glazierhas found that 1% of Clearglass' product is cracked, 1.5% of Strongpane's productis cracked, and 2% of Mirrorglass' and Reflection's products are cracked. Theglazier removes the protective covering from a sheet of glass without looking at themanufacturer's name - in other words, it's a random choice. He finds the glass iscracked. What is the probability it was made by Mirrorglass?it is not a graded quesiton
- If SS between = 40, SSwithin=60,dfbetween=4, and dfwithin =30, then MS within =?Suppose a company charges a premium of $150 per year for an insurance policy for storm damage to roofs. Actuarial studies show that in case of a storm, the insurance company will pay out an average of $8000 for damage to a composition shingle roof and an average of $12,000 for damage to a shake roof. They also determine that out of every 10,000 policies, there are 7 claims per year made on composition shingle roofs and 11 claims per year made on shake roofs. What is the company’s expected value (i.e., expected profit) per year of a storm insurance policy? What annual profit can the company expect if it issues 1000 such policies? Determine the probability of a composition shingle roof claim out of 10,000 = ______ Determine the probability of a shake roof claim out of 10,000 = ______ How many claims are made out of 10,000? = _______ What is the probability of no claims out of 10,000? = _______ How much does each shingle roof claim cost the company, don’t forget each person pays $150…Among the adult population of a certain town 50 per cent are males. 60 per cent are wage earners and 50 per cent are., 45 years of-age or over, 10 per cent of the males are not wage-earners and 40'per cent Of the males are u1ll/er 45.

How many possible combinations of thecar are possible for the manufacturer? What can be doneto limit the number of combinations without limitingcustomer choice?Find the derrivative and show workSuppose, as a rough estimate, we say that there are 20 distinct geons used for object recognition; and a pair of geons can be placed in 10 distinct qualitative relations (geon A on top of geon; geon A to upper left of geon B; geon A to the left of geon B; and so forth). Now, suppose we add a third geon, geon C. Again, each geon comes in 20 varieties and 5 sizes. we'll start by creating a two-geon pair of A and B; then, we decide which of A or B the third geon (C) will be adjacent to, and then we place geon C beside either A or B in one of the 10 allowed relatios. how many distinct three-geon objects do we have in this space?
