To calculate the IQR, we need the radian, which is the middle number of each column, namely (86,82) for each exam.
Above the middle number, we have 5 values. The middle value (of the upper part) is Q3, which is on the third line, or (92,85).
Below the middle number, we also have 5 values. The middle (of the lower half) is Q1, which is on the 9th line (80,78)
The IQR is the difference between Q3 and Q1, namely
(92-80, 85-78) = (12, 7)
Since 12>7, we conclude that the IQR of the mid-term is higher than the final.

C
Step-by-step explanation:
16/21 is the correct answer
Answer:
The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
Step-by-step explanation:
Answer:
(-8x - 12) + (9x + 4)= x-8
(-3p^3 + 5p^2 - 2p) + (3r^2 - 3r)= -3p^3+5p^2-2p+3r^2-3r
( -3p^3 + 5p^2 - 2p) + (-p^3 - 8p^2 -15p)= -4p^3-3p^2-17p
. ( 9r^2+4r-7) + (3r^2-3r)= 12r^2+r-7
