Plug y= -3x in 2x-3y= 22, we have:
2x -3(-3x)= 22
⇒ 2x+ 9x= 22
⇒ 11x= 22
⇒ x= 22/11
⇒ x= 2
y= -3x= -3*2= -6
Final answer: x=2, y=-6~
Answer:
<em></em><em> </em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Let 'X' be the random variable in Poisson distribution
<em>Mean of the Poisson distribution λ or ∝ = 3 per (cm³)</em>
Given n = 5 samples
<u><em>Step(ii):-</em></u>
<em>The probability that at least one sample will contain one or more bacterial colonies</em>
<em>P(X≥1) = 1-P(X< 1) </em>
<em> = 1 - P( X=0)</em>
