Answer:
x (6v+7) x (3v+2)
Step-by-step explanation:
18v^9 + 33v^8 +14v^7
Factor out v^7 from the expression
v^7 x (18v^2+33v+14)
write 33v as a sum
v^7 x (18v^2+21v+12v+14) *like this 21v+12v
Factor out 3v from the expression
v^7 x (3v x (6v+7)+12v+14)
Factor out 2 from the expression
c^7 x (3v x (6v+7)+2(6v+7)
Factor out 6v+7 from the expression
v^7 x (6v+7) x (3v+2)
Answer:
0.933 ; not independent
Step-by-step explanation:
Given :
A - made from natural polished wood
B - made from chrome accent
P(A) = 0.9
P(B) = 0.75
P(AnB) = 0.7
1.) probability of natural wood Giveb that it has chrome accent
P(A|B) = P(AnB) / P(B)
P(A|B) = 0.7 / 0.75
P(A|B) = 0.933
2.)
For an independent event :
P(AnB) = p(A) * p(B)
P(AnB) = 0.9 * 0.75 = 0.675
However, p(AnB) Given here is 0.7, thus the event aren't independent
Answer:
See Explanation
Step-by-step explanation:
(a) Proof: Product of two rational numbers
Using direct proofs.
Let the two rational numbers be A and B.
Such that:
The product:
Proved, because 1/3 is rational
(b) Proof: Quotient of a rational number and a non-zero rational number
Using direct proofs.
Let the two rational numbers be A and B.
Such that:
The quotient:
Express as product
Proved, because 3/4 is rational
(c) x + y is rational (missing from the question)
Using direct proofs.
Let x and y be
Such that:
The sum:
Take LCM
Proved, because 7/6 is rational
<em>The above proof works for all values of A, B, x and y; as long as they are rational values</em>
Step 2 is wrong and i don't know the other question
