Explanation Given: A signed decimal number. Concept used: A phrase structure grammar G = ( V , T , S , P ) consists of a vocabulary V , a subset T of V consisting of terminal symbols. A start symbol S from V and a finite set of productions P . The set V − T is denoted by N are called non-terminal symbols. Every production in P must contain atleast one non-terminal on its left side. Calculation: S → 〈 s i g n 〉 〈 integer 〉 S → 〈 s i g n 〉 〈 integer 〉 ⋅ 〈 p o s i t i v e integer 〉 〈 s i g n 〉 → + 〈 s i g n 〉 → − 〈 integer 〉 → 〈 d i g i t 〉 〈 integer 〉 → 〈 integer 〉 〈 d i g i t 〉 〈 d i g i t 〉 → i , i = 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 0 〈 p o s i t i v e </ To determine (b) To write: The Backus-Naur from of this grammarthat generates all signed decimal number. To determine (c) To construct: The derivation tree for − 31.4

The height of the graph of the probability density function f(x) varies with X as follows (round to four decimal places): X 16 Height of the Graph of the Probability Density Function You are flying out of Terminal 3 at JFK on a Wednesday afternoon between 3:00 and 4:00 PM. You get stuck in a traffic jam on the way to the airport, and if it takes you longer than 12 minutes to clear security, you'll miss your flight. The probability that you'll miss your flight is You have arrived at the airport and have been waiting 10 minutes at the security checkpoint. Recall that if you spend more than 12 minutes clearing security, you will miss your flight. Now what is the probability that you'll miss your flight? ○ 0.5 O 0.25 ○ 0.8333 ○ 0.6667

onsider a random variable x that follows a uniform distribution, with a = 2 and b = 9. What is the probability that x is less than 6? P(x < 6) = 0.2857 P(x < 6) = 0.5714 P(x < 6) = 0.17142 P(x < 6) = 0.4286 What is the probability that x is between 4 and 6? P(4 ≤ x ≤ 6) = 0.2857 P(4 ≤ x ≤ 6) = 0.157135 P(4 ≤ x ≤ 6) = 0.0928525 P(4 ≤ x ≤ 6) = 0.11428
