Answer:
n = 3
Step-by-step explanation:
-18 = -6n - 6 + 2n
-18 = -6n +2n -6 (Combine like terms)
-18= -4n -6
-18+6= -4n -6+6 (Addition Property of Equality)
-12 = -4n
-12/-4 = -4n/-4 (Division Property of Equality)
3=n
The value of 'n' is 3.
Ab=750 and a=b-5, using this value of a in the original equation gives you:
(b-5)b=750
b^2-5b=750
b^2-5b-750=0
b^2-30b+25b-750=0
b(b-30)+25(b-30)=0
(b+25)(b-30)=0
b=30
The answer is
$2,939 (see attachment for formula)
P(A) = 0.36
P(B) = 0.25
P(A and B) = 0.09
Notice how P(A and B) = P(A)*P(B) = 0.36*0.25 = 0.09
So because P(A and B) = P(A) *P(B) in this case, this means A and B are independent events. In other words, the fact that A occurs does not alter the probability of event B.
Answer: independent
