(06.07 MC)  A sample of 10 trucks was taken, and the horsepower to weight was recorded. The computer output for regression is below: What is the equation of the regression line? (4 points)

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 6 No. 7 bars at a depth of 22 in. The top row contains 4 No. 6 bars at a depth of 16.5 in. Determine the effective (centroidal) depth, d, of the steel.

(04.04 MC)Sustainability means developing practices that protect the environment while also providing for human needs. Which of the following changes should be made to help achieve sustainable logging?

Find the polynomial  of degree 3 with integer coefficients, and zeros . ​

In typical U.S. practice, beam depths are rounded to the closest half inch.

(06.07 MC)  A sample of 10 trucks was taken, and the horsepower to weight was recorded. The computer output for regression is below: What is the equation of the regression line? (4 points)

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 2 No. 6 bars. The concrete strength is 7,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.554622 in. and the strain in the reinforcement is εs = 0.078407, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
