(a) Interpretation: If the power of 10 is positive, negative or zero exponents in the standard scientific notation of 0.08331 should be determined. Concept Introduction: Scientific notation for a number is written in such a way that large numbers are written in small decimal form which is then multiplied by the power of 10. For numbers less than 1, the power of 10 in scientific notation has negative exponent and for numbers greater than 1, the power is either zero or has positive exponent.

The figure to the right illustrates the long-run average cost curve for a company
that makes motors.
Suppose the company produces 15 thousand motors per month. Is it experiencing
economies of scale, diseconomies of scale, or constant returns to scale?
If the company produces 15 thousand motors, then it experiences
diseconomies of scale
At what level of output does the firm experience the minimum efficient scale?
The minimum efficient scale occurs when the firm produces

A 25.0 mL sample of a concentrated citrus fruit cordial component (e.g. for lime juice), used in the food & drinks industry, was
diluted to 250 mL in a graduated volumetric flask.
A 25.0 mL sample of this diluted solution, required, on average, 22.5 mL of a standard 0.100 molar sodium hydroxide solution
using phenolphthalein indicator for the titration end-point.
A) 0.0075
