This member of the Enterobacteriacea gave these reactions: H2S (TSI) Negative Ornithine Negative Lysine Positive Citrate Positive Urea Positive Phenylalanine Negative Motility Negative What is this organism?

A gram-negative rod from a stool culture produces red colonies (colorless) with black centers on xylose lysine decarboxylase (XLD) agar. When the organism is inoculated to triple sugar iron agar (TSIA) and lysine iron agar (LIA), it should appear as which of the sets of tubes shown in the image?

The acid/acid reaction shown in the photograph of a Triple Sugar Iron (TSI) Agar reaction tube indicates the recovery of a bacterial species that ferments both glucose and lactose. Also, is the absence to the formation of any black pigment which indicates one of the Enterobacteriaceae that does not produce hydrogen sulfide (H2S). Select the species producing this acid/acid, H2S negative reaction.

All of the following Enterobacteriaceae below are appropriately matched with the characteristic listed, EXCEPT:

Discuss actions you can take to manage risk in constructing an investment portfolio and what are the benefits of doing so? In addition to general actions you might take, describe a couple of techniques that we have discussed and how they are intended to manage risk.

The EPA fuel economy estimates for automobile models tested recently predicted a mean of 24.8 mpg and a standard deviation of 6.2 mpg for highway driving.  Assume that fuel economy has a bell-shaped distribution.  (Use the empirical rule). What percent of automobiles will have a fuel economy lower than 18.6 mpg on the highway?
