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.
Honky-tonk music often provided relief from the daily pressures of work on in the city, in the form of drinking and dancing is it true or false
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.

look at these two triangles triangle b is a reflection of triangle a
Triangle B is a reflection of Triangle A.
Triangle B is a mirror image of Triangle A. The corresponding sides, angles, and vertices of the two triangles will be equal in measure, but they will face in opposite directions.
Reflection is a transformation in which a figure is flipped over a line to create a mirror image. In the case of triangles, a reflection would involve flipping the triangle over a line to create a new triangle that is a mirror image of the original.
When Triangle B is a reflection of Triangle A, it means that Triangle B is created by reflecting Triangle A over a line.
The line of reflection is an imaginary line that serves as the axis of symmetry for the reflection. It is a line that each point on Triangle A is reflected across to create the corresponding point on Triangle B.
When Triangle B is a reflection of Triangle A, the corresponding sides and angles of the triangles will be equal in measure. This is because reflection preserves the shape and size of the original figure.
The vertices of Triangle B will be the mirror image of the vertices of Triangle A. For example, if vertex A in Triangle A is reflected to vertex A' in Triangle B, the distance between the line of reflection and vertex A will be equal to the distance between the line of reflection and vertex A'.
Similarly, the angles in Triangle B will be equal in measure to the corresponding angles in Triangle A.
The sides of Triangle B will have the same lengths as the corresponding sides of Triangle A.
Overall, when Triangle B is a reflection of Triangle A, the two triangles will have the same shape and size but will be facing in opposite directions.
By understanding the concept of reflection and the properties of a reflection, we can conclude that Triangle B is a mirror image of Triangle A. The corresponding sides, angles, and vertices of the two triangles will be equal in measure, but they will face in opposite directions.

C increase income for increased work.increase income for increased work. D prove how interesting the study was.
A scientist repeat an experiment if he/she did not make a mistake in the first one to "check to see if the procedure was correct and nothing was left out." (Option D)
What is an experiment?An experiment is a technique that is carried out to support or deny a hypothesis, or to test the efficacy or probability of something that has never been done before. Experiments shed light on cause-and-effect relationships by revealing what happens when a certain element is changed.
The experimental technique entails modifying one variable to see if it affects another variable. To test a hypothesis, this strategy employs controlled research methodologies and random assignment of study volunteers.
