X + 2/3 = -2(4/5x-7)
Is equivalent to -2(x+2/3)=4/5x-7
So the answer would be A
Answer:
the required probability is 0.09
Option a) 0.09 is the correct Answer.
Step-by-step explanation:
Given that;
mean μ = 7
x = 4
the probability of exactly 4 bridge construction projects taking place at one time in this state = ?
Using the Poisson probability formula;
P( X=x ) = ( e^-μ × u^x) / x!
we substitute
P(X = 4) = (e⁻⁷ × 7⁴) / 4!
= 2.1894 / 24
= 0.0875 ≈ 0.09
Therefore the required probability is 0.09
Option a) 0.09 is the correct Answer.
option (D) 28 √6 is the answer
Explanation :
p =3√6 + 2√24 + 7√54
3√6 + 2√2×2×6+ 7√3×3×6
3√6 +2 ×2√6 + 7 ×3√6
3√6 +4√6 + 21√6
28√6
The answer 3 would be the right answer
