It is true to state that Honky-tonk music often provided relief from the daily pressures of work on in the city, in the form of drinking and dancing.
What is Honky-tonk music ?The honky-tonk style, which became popular in the 1950s, is most recognized for its focus on rhythm. Because the pianos at these no-frills establishments were frequently beat-up and out-of-tune, harmony and melody were less crucial to the overall sound.
Although the origin of the name is uncertain, honky tonk originally referred to bawdy variety performances and the theaters that housed them throughout the West (Oklahoma, Indian Territories, and Texas). The first published reference of them refers to them as "variety theaters" with "variety shows" as the entertainment.

There are 13
people in an office with 6 different phone lines. If all the lines begin to ring at once how many groups of 6 people can answer these lines
Answer:
1716
Explanation:
If there are 13 people in the office and only 6 phone lines, then only 6 people can answer the phone lines at any given time.
To find out how many different groups of 6 people can answer the phone lines, we can use the combination formula:
nCr = n! / r!(n - r)!
where n is the total number of people (13) and r is the number of people we want to choose (6).
So the number of different groups of 6 people that can answer the phone lines is:
13C6 = 13! / 6!(13 - 6)! = 13! / 6!7! = (13x12x11x10x9x8) / (6x5x4x3x2x1) = 1716
Therefore, there are 1716 different groups of 6 people that can answer the phone lines.
Thus, 1,716 different 6-member groups can answer the lines.
