(06.06 LC) A scientist is interested in the relationship between the number of eggs hatched per day for frogs (y) and temperature. Based on the collected data, the least-squares regression line is ŷ = 15.66 + 3.58x, where x is the number of degrees by which temperature exceeds 60 degrees Fahrenheit. Which of the following statements best describes the meaning of the slope of the least-squares regression line? (3 points)

A beam has dimensions of b = 14 in., h = 30 in., and d = 27.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 2.80342 in., determine the strain in the reinforcement.
