Step-by-step explanation:
180= 90+30+20x 90+30=120 180-120= 60
20x=60 x=3
Answer:
x = -1
Step-by-step explanation:
Solve for x:
12 = 24 - 4 (-6 x - 3)
-4 (-6 x - 3) = 24 x + 12:
12 = 24 x + 12 + 24
Grouping like terms, 24 x + 12 + 24 = 24 x + (12 + 24):
12 = 24 x + (12 + 24)
12 + 24 = 36:
12 = 24 x + 36
12 = 24 x + 36 is equivalent to 24 x + 36 = 12:
24 x + 36 = 12
Subtract 36 from both sides:
24 x + (36 - 36) = 12 - 36
36 - 36 = 0:
24 x = 12 - 36
12 - 36 = -24:
24 x = -24
Divide both sides of 24 x = -24 by 24:
(24 x)/24 = (-24)/24
24/24 = 1:
x = (-24)/24
The gcd of -24 and 24 is 24, so (-24)/24 = (24 (-1))/(24×1) = 24/24×-1 = -1:
Answer: x = -1
Answer: p(a given b) = p(a and b) / p(b)
a is the probability that they score.
b is the probability that they cross the blue line.
p(a and b) is given as .005
this is the probability that they cross the blue line and score.
p(b is given as .6
that's the probability that they cross the opposing blue line.
the formula becomes:
p(a given b) = .005 / .6 = .0083333333.....
that's what i get using the p(a given b) formula.
