For X, 90% of 78% will work. For Y, 10% of 65% will work. *10% is the rest of the bulb supply in the market. So, the probability that a purchased bulb will work is: 0.90(0.78) = .702 0.10(0.65) = 0.065 The combined probability then is 70.2 + 6.5 = 76.7% ANS B

Given that -1 ≤ v ≤1, -2 ≤ u ≤ -0.5 and -2 ≤ z ≤ -0.5 and w = vz/u, then which of the following is necessarily true ?
A. -0.5 ≤ w ≤ 2 B. -4 ≤ w ≤ 4 C. -4 ≤ w ≤ 2 D. -2 ≤ w ≤ 0.5 E. None of these
B. -4 ≤ w ≤ 4
Explanation : We try to get an upper bound on the value of w. After taking a look at the options we figure it out that if we take v=-1,z=-2 and u=-0.5. we get the lower bound as -4. If we take v=1, z=-2 and u=-0.5 we have the upper bound as 4. Hence, the right option is 2.ie -4 ≤ w ≤ 4 Answer : B

What is the measurement for the amount of water vapor in the air? A. ambient B. humidity C. haze D. saturation
B. humidity
A: Humidity is a measure of the amount of water vapor in the air. When humidity is high, sweat evaporates more slowly because there is already a lot of water vapor in the air. The slower evaporation rate reduces the potential for evaporative cooling.
