A manufacturer of medical supplies produces 1-liter bags of saline solution. The cost to produce x thousand bags of saline is given by the cost function C(x) = 1.7x2 - 4.2x + 2.8, where C is the cost in
thousands of dollars. Find the cost to produce 3000 units.

Arrange these numbers from least to greatest 3/5 5/7 2/9

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.
