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.

step-by-step explanation:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
