An agriculturalist working with australian pine trees wanted to investigate the relationship between the age and the height of the australian pine. a random sample of australian pine trees was selected, and the age, in years, and the height, in meters, was recorded for each tree in the sample. based on the recorded data, the agriculturalist created the following regression equation to predict the height, in meters, of the australian pine based on the age, in years, of the tree. predicted height 0.29+048 (age) which of the following is the best interpretation of the slope of the regression line?
a. the height increases, on average, by 1 meter each 0.48 year.
b. the height increases, on average, by 0.48 meter each year.
c. the height increases, on average, by 0.29 meter each year.
d. the height increases, on average, by 0.29 meter each 0.48 year.
e. the difference between the actual height and the predicted height is, on average, 0.48 meter for each year.

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
