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.
Answer:
y = 
x + 1
Step-by-step explanation:
We have 8 - 5y = -2x
Rearranging gives;
5y = 2x + 8
Dividing through by 5 gives;
y = x + 
Simplifying gives;
y = x + 1
This is a standard linear equation form.
Answer:
3 , 4 , 5 can formed right triangle
Step-by-step explanation:
In any triangle if the sum of the squares of the smallest two sides equals the square of the third side, then the triangle is right triangle
∵ 16² + 32² = 1280
∵ 36² = 1296 ≠ 1280 ⇒ Not right Δ
∵ 3² + 4² = 25
∵ 5² = 25 ⇒ right Δ
∵ 8² + 12² = 208
∵ 16² = 256 ≠ 208 ⇒ Not right Δ
∵ 9² + 10² = 181
∵ 11² = 121 ≠ 181 ⇒ Not right Δ
