Answer:
G1 = -5 G2 = -1
Step-by-step explanation:
plug in the values given into X and solve
g1= 1/4(-4) -4
g1 = -1 -4
g1 = -5
g2= 1/4(12) -4
g2= 3 -4
g2= -1
Answer:
Color : ___Green __yellow ___purple __ Grey
Prob : ____0.30 ___0.10 ______ 0.35 ___ 0.25
4 pins
Step-by-step explanation:
Color : ___Green __yellow ___purple __ Grey
Prob : ___. _______________ 0.35 ___ 0.25
P(green) = 3 * P(yellow)
ΣP = 1
Let
P(yellow) = x
P(green) = 3x
Hence,
x + 3x + 0.35 + 0.25 = 1
4x + 0.60 = 1
4x = 1 - 0.60
4x = 0.40
x = 0.4 / 4
x = 0.1
Hence,
P(yellow) = 0.1
P(green) = 0.1 * 3 = 0.3
Color : ___Green __yellow ___purple __ Grey
Prob : ____0.30 ___0.10 ______ 0.35 ___ 0.25
B)
If there are 14 pins in bag :
Number of green pins :
X * p(x)
14 * 0.3
= 4.2
= 4 pins
Answer:
20
Step-by-step explanation:
Since that is a true equation, you can substitute 7x - 7 y for 4 and simplify.
5(7x - 7y)
5(4)
20
Answer:
1:50
Step-by-step explanation:
Answer:
7y+13=5y-3
7y=5y-16
2y=-16
Y=-8
