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:
- 2 3/5 - 1 2/3
= -2 9/15 - 1 10/15
= (-2 9/15) + (- 1 10/15)
= -3 19/15
= -4 4/15
Answer is B
-4 4/15
Answer:
2 y = 100
10 y = 20
20 y = 10
Step-by-step explanation:
To find the answer divide Y by X since y is 200 in the first and x is 1 divide 200 by the second one and you will find you answer.
It is y=x-150 because x−150+150=y+150
