For range it’s highest number minus lowest number so:
28 - 21 = 7
For median it’s the middle number:
Since there’s two we add them and dive it by two so:
25 + 24 = 49 dived by 2 = 24.5
For mode it’s most occurring number in this case :
All of them appear twice so none of them are the mode
Let a =107° and b=42°;
So cos 107° cos 42° + sin 107° sin 42° = cosa.cos42 + sina.sinb = cos(a-b)
and cos 107° cos 42° + sin 107° sin 42° = cos(107-42) = cos(65°)
Answer:
local calls per 1 long distance call.
Step-by-step explanation:
Local calls 
Long distance calls 
For 20 long distance calls local call ![=35 For 1 long distance calls local call [tex]=\frac{35}{20} =\frac{7}{4}](https://tex.z-dn.net/?f=%3D35%20%3C%2Fp%3E%3Cp%3EFor%201%20long%20distance%20calls%20local%20call%20%5Btex%5D%3D%5Cfrac%7B35%7D%7B20%7D%20%3D%5Cfrac%7B7%7D%7B4%7D)
