The manufacturing cost of the item that takes the most time to manufacture is approximately what percent greater than the cost of the item that takes the least time to manufacture?
$$°C =\frac{5}{9}(°F -32)$$

The formula above can be used to convert temperatures from degrees Fahrenheit(°F) to degrees Celsius (°C), where (°F is a certain temperature expressed in degrees Fahrenheit and °C is the same temperature expressed in degrees Celsius. What was the maximum temperature in Atlanta, in degrees Celsius, rounded to the nearest degree?

The standard deviation of the numbers in list K is a number between 12 and 15 inclusive. If a new list is formed by multiplying each number in list K by 3 which of the following values could be the standard deviation of the numbers in the new list?

Indicate all such values.
