2x + 2x + 2x = 12
6x = 12
x = 2
2x - 1 = 3
2x = 3 + 1
2x = 4
x = 2
x = 2 is the answer
Answer:
180 i think
Step-by-step explanation:
Answer:
It is binomial:
p= 0.75 = 75%
1-p = 0.25 = 25%
N = 10
k=7
"seven successes in 10 trials"
(10 choose 7) (0.75)^7 ( 0.25)^3 =
(10*9*8 / 3*2) * (0.75)^7 ( 0.25)^3 =
(5*3*8) (0.75)^7 ( 0.25)^3
120 (0.75)^7 ( 0.25)^3
= 0.25028228759765625
or just over 25%
Step-by-step explanation:
√5m / √5n =
(√5m * √5n ) / (√5n * √5n)
= (√(5m * 5n) ) / (5n)
= (√(25m * n) / (5n)
= √25 * √(m * n) / (5n)
= 5 * √(m * n) / (5n)
= √(m * n) / n
