In a 1993 study, researchers took a sample of people who claimed to have had an intense experience with an unidentified flying object (ufo) and a sample of people who did not claim to have had such an experience (spanos et al., 1993). they then compared the two groups on a wide variety of variables, including iq. the group of 25 people who claimed to have had an intense experience with a ufo had a mean iq of 101.6, and the standard deviation of these iqs was 8.9. a control group of 53 community members who had not reported ufo experiences had a mean iq of 100.6 with a standard deviation of 12.3.

answer: i believe it’s 245.04

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

answer: y=0 if that is what u r looking for
