Blanca creates decorative wall hangings. She wants to look at the relationship between the diagonal length of the hangings and their weight. The data show a linear pattern with the summary statistics shown below:

mean

standard deviation

5 = 24.1

8 = 12

2 = diagonal length (inches)

y = weight (pounds)

y = 12.9

8y = 16.2

t = 0.9

Find the equation of the least squares regression line for predicting the weight of the wall hanging from

its diagonal length

Round your entries to the nearest hundredth.

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
