GREYUIT [131]

Answer:

87/3

Step-by-step explanation:

Here we are given the expression:

\frac{x^{2}+6}{x-6}

Now we have to find the value of this expression when x equals 9.

So plugging the value of x as -9 in the given expression:

\frac{x^{2}+6}{x-6}

=\frac{(9)^{2}+6}{9-6}

Katyanochek1 [597]

Answer:

2 sales

Step-by-step explanation:

Based on the plot of discrete probability, it can be seen that the distribution is symmetrical and the peak occurs at the stock of 30. If there is a sale of less than 30 such as 20 or 25, the seller is at a loss. Similarly, if the demand is above 30 such as 35 or 40, the seller is also at a loss. Therefore, there is approximately 2 sales to be lost each day based on the decision made by the seller.
