Probability of any event = ( favourable outcomes ) /total number of outcomes
Probability of = 3/10 + 2/9 = 
The ionic compound produced would be Aluminum Oxide or Al2O3.
- The answer is C
144 classes. each class is 10 minutes. 6X24= 144
Let me think this again and I will get back later!! 2.234 graph
Answer:
Step-by-step explanation:
If θ is the angle between two vectors u and v, then cosθ = (u·v) / [llull llvll]
u·v = (8)(9) + (7)(7) = 121
llull = √[(8)2 + (9)2] = √145 llvll = √[(7)2+(7)2] = 7√2
So, cosθ = 121/ [7√290]
= 1.015052094
θ = Cos-1(1.015052094) ≈ 3.3
