Answer:
14
Step-by-step explanation:
Given that a package delivery company purchased 14 trucks at the same time. Five trucks were purchased from manufacturer A, four from manufacturer B, and five from manufacturer C. The cost of maintaining each truck was recorded.
No of companies = 3
No of items in total = 14
Total df = 17-1=16
degrees of freedom between groups = 3-1 =2
Hence degrees of freedom for denominator
=
Let's check.
x = 5π/24
4x = 5π/6
cos 4x = cos(5π/6) = cos 150° = -√3/2
cos² 4x = (-√3/2)^2 = 3/4
4 cos² 4x -3 = 4 (3/4) - 3 = 0
Answer: TRUE
