Construction of the Tower of Pisa was completed in 1360. By 1990, the tilt of the tower was so severe that it was closed for renovation. Renovators were able to reduce the tower's 1990 tilt by 17 inches. The resultant tower leans 13.5 feet (162 inches) off the perpendicular. When the tower was reopened in 2001, officials forecast that it would take 300 years for the tower to return to its 1990 tilt.(a) Construct a linear formula that models the lean of the renovated tower, where l is the number of inches from the perpendicular and t is the number of years since 2001.The formula is: 162+(17/300)t Use the formula from part (a) to predict the lean of the tower in 2150. (Round your answer to two decimal places.

The two-way table shows the ages of the players on different soccer teams. A 6-column table has 4 rows. The first column has entries 8 years old, 9 years old, 10 years old, Total. The second column is labeled Team A with entries 4, 9, 2, 15. The third column is labeled Team B with entries 6, 4, 3, 13. The fourth column is labeled Team C with entries 8, 3, 5, 16. The fifth column is labeled Team D with entries 3, 7, 4, 14. The sixth column is labeled Total with entries 21, 23, 14, 58. Which statement is true? The probability that a randomly selected player on Team A is 8 years old is StartFraction 4 Over 21 EndFraction. The probability that a randomly selected 8-year-old player is on Team C is StartFraction 16 Over 21 EndFraction. The probability that a randomly selected player on Team C is 10 years old is StartFraction 5 Over 16 EndFraction. The probability that a randomly selected 10-year-old player is on Team B is StartFraction 13 Over 58 EndFraction.

Researchers have created every possible "knockout" line in yeast. Each line has exactly one gene deleted and all the other genes present (Steinmetz et al. 2002). The growth rate - how fast the number of cells increases per hour - of each of these yeast lines has also been measured, expressed as a multiple of the growth rate of the wild type that has all the genes present. In other words, a growth rate greater than 1 means that a given knockout line grows faster than the wild type, whereas a growth rate less than 1 means it grows more slowly. Below is the growth rate of a random sample of knockout lines: 0.8, 0.98, 0.72, 1, 0.82, 0.63, 0.63, 0.75, 1.02, 0.97, 0.86 What is the standard deviation of growth rate this sample of yeast lines (answer to 3 decimals)?
