(04.02 MC)Which of the following best explains why the diversity of organisms decreases as you move from shallow seas to deep oceans?

(04.02 MC)  When a certain coin is flipped, the probability of obtaining a tails is 0.60. Which of the following is the probability that tails would be obtained exactly 10 times when the coin is flipped 20 times? (4 points)

A beam has dimensions of b = 14 in., h = 28 in., d’ = 2.5 in., and d = 25.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 4.199 in., determine the strain in the compression reinforcement, ε’s.

(05.02 MC)A gene that controls an observable trait in birds has three different alleles. Which of the following best describes how gene flow would affect the genetic makeup of this population?

A beam has dimensions of b = 14 in., h = 26 in., d’ = 2.5 in., and d = 23.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 3,700 psi, and the yield strength of the reinforcement is 60,000 psi. For the results given below, determine the strength Mn for this beam.a = 3.809 in. (depth of concrete stress block)Cc = 165.8 kips (compressive force in concrete)Cs = 23.8 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

(06.07 LC)  The mean and standard deviation for number of battery crimes in the U.S. from 1985 to 2000 are x̄ = 326,845 and sx = 27,569. The mean and standard deviation for number of property crimes in the U.S. for the same time period are ȳ = 634,235 and sy = 42,268. The correlation coefficient is r = 0.92. Find the equation for the least-squares regression line for number of property crimes compared with number of battery crimes. (4 points)

(04.06 MC)  Given a normal distribution with a mean of 125 and a standard deviation of 14, what percentage of values is within the interval 111 to 139? (4 points)
