Step-by-step explanation:
We are told that for a large data set of a average student grades, the third quartile Q3 is found 78.5.
Since we know that third quartile represents the number such that 75% of the data is less than this number. Third quartile is the middle value between median and the highest value of a data set. Third quartile is also known as upper quartile. Third quartile splits lower 75% data from highest 25% of data.
Therefore, third quartile represents that 75% of student grades are less than 78.5 and 25% of students grades are greater than 78.5.

Answer:
Coordinate of Point A is (-11, 15)
Step-by-step explanation:
M -- (-3, 7)
B -- (5, -1)
Therefore, (5 + x)/2 = -3
x = -11
(-1 + y)/2 = 7
y = 15
Therefore Point A is (-11, 15)
Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.
