Solving for y:
4x-3y=10. (subtract 4x on both sides)
-3y=-4x+10. (divide by -3 on both sides)
y=4/3 x+10/3
We have cos( x - y ) = cosxcoy + sinxsiny <=> cos ( π - x ) = cosπcosx + sinπsinx <=> cos ( π - x ) = (-1)cosx + 0sinx = -cosx;
Answer: where are the graphs?
Step-by-step explanation:
Answer:
14.2, 16.96
Step-by-step explanation:
given is a probability distribution of X
X is discrete taking values as 7, 11, 15 and 19
X 7 11 15 19 total
p 0.10 0.35 0.20 0.35 1
x*p 0.7 3.85 3.0 6.65 14.20
x^2*p 4.9 42.35 45 126.35 218 .60
Hence mean = sum of prob (x) = 14.20
