Answer:
p=0.8765
Step-by-step explanation:
Let the following variables be represented as below:
Total Set,t=17
Def,d=3
Not Def,n=14
Purchases,p=8
The number of ways the hotel can receive at least one defective set in a purchase of 8 sets is calculated using the combination:-

So the proability of getting at least one defective unit is 0.8765
Answer:
The depth of the reflector is 0.84 feet
Step-by-step explanation:
<em>(See the figure below)</em>
The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:
(1)
With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:
(2)
Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:
, solving for y
