Answer:
This statement is true for any N vectorial space.
By definition u·v=|u|·|v|·cos(α), where α is the angle between u and v.
If -1≤cos(α)≤1, we can assume:
|u·v|=||u|·|v|·cos(α)|=|u|·|v|·|cos(α)|≤|u|·|v|
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
1st number=7 and 2nd number =11
Step-by-step explanation:
5x+2y=57
x+y=18
7+11=18
(5*7)+(2*11)=57
Answer:


Step-by-step explanation:
Given the system of linear equations


solving by the elimination method







so

now solving for y
