How do epidemiologists use the concepts of frequency, pattern, and determinants to understand the spread of diseases?

Epidemiologists use the concepts to determine the spread of disease as they expand exponentially.

Explanation:

one of the important facets of any epidemic is that these diseases do not spread like moral.

They spread exponentially thus all the studies conducted on the are not on the biases of conventional numbers but are done on the basis of logarithm.

The logs are thus used along with the frequency of cases in an area, creating containment zones and also understanding the passage of the spread and where it will reach.

All these are the tactics used by them.

roosevelt believed that in light of the country's recent military successes, it was unnecessary to use force to achieve foreign policy goals, so long as the military could threaten force. this belief, and his strategy of “speaking softly and carrying a big stick,” shaped much of roosevelt's foreign policy.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
