Vertex Angle = 180 -54 -54Vertex Angle =72 degrees
2000 - 800 = 1200 moving forward. That is the direction of least resistance.
Algebra is the study of operations, how an object is varied from a set of numbers. Moreover, calculus is the study of change among these numbers, the chain or algorithmic patterns of change or just random sets of change is the field that calculus values which algebra can not apply or understand. However with the application of both geometry and algebra, calculus is formed. It has the direction/shape and the set of operations at its disposal.
Answer:
50% of all students scored more than 48 marks.
Step-by-step explanation:
1) The baseline of the box, in a box plot is the first quartile, the line in the middle is the median or Q2 and the last line (or top line) is the third quartile. Namely,
2) The Question says "nobody took 30, 48 or 70 as their grades. But 120 students gained less than 70", i.e. 120 are within the 75% of the sample.
3) If then 50% of the students scored more than 48. And 50% of the students scored less than 48. That is also known as the Median.
So 50%, the half of all students scored more than 48 marks.
