You would best do this by completing the square on the quadratic and subbing in the vertex they give you, like this:
Since the y coordinate of the vertex is 1/2 and we need to solve for c, set the
equal to 1/2 and solve for c, which is the whole point of what we are doing, right?
and
and c = 4. So that's our answer!
Answer:
x+1/x-1 +1 / x+1/x-1 -1= x
Answer:
X-intercept: -10
Y-intercept: -45
(-10),(-45)

Using it's concept, it is found that there is a 0.3043 = 30.43% probability of at least one O-ring failing.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, of the 23 flights, 7 had at least one failure, hence the probability is given by:
p = 7/23 = 0.3043.

Answer:
It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
Step-by-step explanation:
In this case, the company will hire four <em>different</em> applicants from a group of 40 people for 4 <em>different</em> jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:
(1)
Where:
- Total of applicants.
- Selected applicants.
If we know that 
and 
, then the number of possibilities is:
There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
