Answer:
Step-by-step explanation:
1 cubic foot is 12 * 12 * 12 cubic inches.
1 cubic foot = 1728 cubic inches.
1 cubic foot = 1728 cubic inches
x cubic feet = 3456 Cross multiply
1728 x = 3456 * 1 Divide by 1728
x = 3456/1728
x = 2 cubic feet.
The other way to do this is
3456 cu inches [1 cubic Foot/1728 cubic inches] note that the units cancel and you are left with 1 division problem.
The question still comes to 2.
Answer:
And using the probability mass function we got:
And replacing we got:

Step-by-step explanation:
Let X the random variable of interest "number of students graduated", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:
And using the probability mass function we got:
And replacing we got:

Answer:
b > 12.71
Step-by-step explanation:
Here in this question we have to solve the inequality equation given for b (An unknown variable}
Now, the equation is 
⇒ 
We are taking the base of the log here is 10.
So,
{Since
and
}
⇒ b > 12.71 (Approximate) (Answer)
