Suppose that a randomly selected used battery outputs voltages from 7.6 volts to 11.6 volts, uniformly distributed, depending on how much it has been used. Let x = random battery voltage. Give the height of the probability curve (this is its probability density function). For the following probabilities, keep 3 significant figures. Compute P (x > 8.4). Compute P (x 4.3). Compute P (x
