The following box plot represents the average heights of the students in Mr. Taylor's fourth grade math class. What is the median of this data set? What is the interquartile range of this data set?

Median = 140 cm

Interquartile range = 3cm

Step-by-step explanation:

=>The median value of a data set is usually represented by the vertical line that divides the rectangular box in a box plot.

Therefore, the median value of the data set in the box plot above = 140 cm

=>Interquartile range is the difference between the upper quartile (Q3) and lower quartile (Q1) of a data set.

Upper quartile (Q3) is indicated at the end of the rectangular box in a box plot, to our far right, while the lower quartile is indicated at the beginning of the rectangular box to our left.

In the data set above,

Q3 = 141

Q1 = 138

IQR = 141 - 138 = 3 cm

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:
