the mean of monthly salaries of 15 worker of a company is 2930 .A new worker with monthly salary 3138 join the company. Find the new mean monthly salary of 16 workers

Explanation:

S = sum of the salaries of the first 15 employees

S/15 = mean of the 15 salaries

S/15 = 2930

S = 15*2930

S = 43950

The 15 workers salaries add to 43950.

If we add on a new 16th salary of 3138, then the sum bumps up to

S+3138 = 43950+3138 = 47088

This is the sum of the 16 workers salaries. Divide this over 16 to get the new average

47088/16 = 2943

The new mean is 2943

It is larger than the old mean because the 16th salary is larger than the mean. Effectively this new salary pulls on the mean to make it larger. With very distant outliers, the mean is pulled a lot which often causes problems. So this is why the median is a better measure of center in those situations. Either that measure of center, or using a trimmed mean works as well.

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
