In the theory of finance, a market for any asset or commodity is said to be efficient if items of identical quality and other attributes (such as risk, in the case of stocks) are sold at the same actual average price. a geneva-based oil industry analyst wants to test the hypothesis that the spot market for crude oil is efficient. the analyst chooses the rotterdam oil market, and he selects arabian light as the type of oil to be studied. (differences in location may cause price differences because of transportation costs, and differences in type of , in the quality of affect the price. therefore, both the type and the location must be fixed.) the analyst also notes that during the month of february 2008, the "official" price of a barrel of crude oil did not change. a sample of eight observations from each of four sources of the spot price of a barrel of oil during february is collected. data, u. s. dollars per barrel, are as follows:

the statemwnt is the company makes small and large snow cone cups.

large=it holds more then the small

small=it holds less then the large

answer: haha (: i’ll go see what it is

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
