Acommon equation used in business is a demand equation. it expresses the relationship between the unit price of some commodity and the quantity demanded. in the equation, p represents the unit price and x represents the quantity demanded in thousands. a company sells desk lamps and has found that the demand equation for a certain style of desk lamp is given by the equation p equals negative x squared plus 23. find the demand for the desk lamp if the price is $7 per lamp.

The demand of the desk is 4000 units

Step-by-step explanation:

From the question we know that p is equals negative x squared plus 23, that can be written as:

Where p is the unit price and x represent the quantity demanded in thousands. Replacing p by 7 and solving for x, we get:

Since x is given in thousands of units, if the price is $7, the demand of the desk is 4000 units.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
