Chapter 3.1, Problem 1E

Determine whether each of the following relation is a function with domain { 1 , 2 , 3 , 4 } . For any relation that is not a function, explain why it isn’t.

f = { ( 1 , 1 ) , ( 2 , 1 ) , ( 3 , 1 ) , ( 4 , 1 ) , ( 3 , 3 ) }
f = { ( 1 , 2 ) , ( 2 , 3 ) , ( 4 , 2 ) }
f = { ( 1 , 1 ) , ( 2 , 1 ) , ( 3 , 1 ) , ( 4 , 1 ) }
f = { ( 1 , 1 ) , ( 1 , 2 ) , ( 1 , 3 ) , ( 1 , 4 ) }

Suppose the random variable X is normally distributed with mean 80 and standard deviation 16. Find following probabilities. Find ‘b’ such that P(X ≥ b) = 0.975. Find the probability using a normal distribution table AND using ti-83 calculator. SHOW ALL STEPS PLEASE.

Thumbi Irrigation Scheme in Mzimba district is under threat of flooding. In order to mitigate against the problem, authorities have decided to construct a flood protection bund (Dyke). Figure 1 is a cross section of a 300m long proposed dyke; together with its foundation (key). Survey data for the proposed site of the dyke are presented in Table 1. Table 2 provides swelling and shrinkage factors for the fill material that has been proposed. The dyke dimensions that are given are for a compacted fill. (1) Assume you are in the design office, use both the Simpson Rule and Trapezoidal Rule to compute the total volume of earthworks required. (Assume both the dyke and the key will use the same material). (2) If you are a Contractor, how many days will it take to finish hauling the computed earthworks using 3 tippers of 12m³ each? Make appropriate assumptions. DIKE CROSS SECTION OGL KEY (FOUNDATION) 2m 1m 2m 8m Figure 1: Cross section of Dyke and its foundation 1.5m from highest OGL 0.5m…
