10 people who build at the same rate can frame a house in 6 days. That means it will take one person 
days to finish the house.
Which means that it will take 4 people 
days to finish the house.
So, the fractional part of the house 4 people can frame in 3 days will be 
Thus, Option D is the correct answer.
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:
Answer:
103.67 dollars.
Step-by-step explanation:
The perimeter of the garden = 2 * π * 6 feet.
So the cost is 2.75 * 12π dollars.
= 103.67 dollars.
Add the zeros on to 7.5 to which you would move the decimal and it should be like this 750.0 or 750
Answer:
C
Step-by-step explanation:
You have to divide both sides by the coefficient of x
