Suppose we have information about the supermarket purchases of 100 million people. each person goes to the supermarket 100 times in a year and buys 10 of the 1000 items that the supermarket sells. we believe that a pair of terrorists will buy exactly the same set of 10 items (perhaps the ingredients for a bomb? ) at some time during the year. if we search for pairs of people who have bought the same set of items, would we expect that any such people found were truly terrorists?

answer: x=3 and y=4

step-by-step explanation:

idk

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
