Answer:
y=21
Step-by-step explanation:
x-4=3x x+6=7 then multiply 7x*3x =21so then just make it into the y so y=21
given,
height of triangle(h)=3.5 in.
base of triangle (b)=4 in.
length of side of triangle(s)= 4 in.
length of prism(l)=9 in.
we have,
surface area of traingular prism( A)=bh+2ls+lb
=4×3.5+2×9×4+9×4
=14+72+36
=122 square inches
Answer:
Step-by-step explanation:
Given that the probability that an American company will open a location in Shanghai, China is 0.7.
The probability that it will open a location in Beijing, China is 0.4.
The probability that it will open a location in either Shanghai or Beijing or both is 0.8.
the probability that the company will open a location in:
(a) both Shanghai and Beijing :

P(both) = 0.3
(using addition theory of probability for union of sets)
(b) neither Shanghai nor Beijing
= 1- P(AUB)

(c) Beijing but not in Shanghai?
P(Beiging)_P(both) = 
(d) Shanghai given that it opens a location in Beijing
=P(Both)/P(Beijing) =
