2 less than x less than 6. We begin with inequality A by adding 10 to both sides. Next, we divide by 3.5 on both sides, resulting in the solution for inequality A being the interval (2,∞). For inequality B, we add 9 to both sides and then divide by 8 on both sides. The solution for inequality B is the interval (-∞,6). Therefore, the solution set for the compound inequality is (2,∞) ∩ (-∞,6) = (2,6).
P(volleyball and baseball) = 4/200 x 100 = 2%
P(volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.
Thus, 25% of students participate in either volleyball or baseball.
