The given equation of parabola is:
Part 1) Focus of the Parabola
In order to find the focus and equation of directrix, we first have to convert the given equation to standard form of parabola.
The focus of the general equation of parabola shown below lies at (h+p, k)
Comparing our equation to the general equation we get:
h=0
k=0
p=6
So the focus of given parabola will be (0+6, 0) = (6,0)Part 2) Directix of the ParabolaThe directrix of the general parabola shown above lies at:
x = h - p
Using the values of h and p, we get
x = 0 - 6
x = -6
So, the directrix of the given parabola has the equation x = -6
Answer:
The complete answer is explained below.
Step-by-step explanation:
The problem is demanding to simply determine the number of years each color light would last.
We know the following information from the question:
- As it is clear that a red light remains TURNED ON 50% of the time.
- Green remains TURNED ON 42% of the time
- Yellow remains TURNED ON 8% of the time.
Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.

Answer:
B) 11
Step-by-step explanation:
To find the % of something simply turn 22% to a decimal (.22) then times it by the number you want .22 * 50 = <em><u>11</u></em>
Answer:
a) P(6) = 0.0097
b) P(More than 3) = 0.1611
Step-by-step explanation:
For each question, there are only two possible outcomes. Either it is guessed correctly, or it is not. Questions are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
A student takes a multiple-choice test that has 11 questions.
This means that 
Each question has five choices.
This means that 
(a) Find P (6)
This is P(X = 6).
P(6) = 0.0097
(b) Find P (More than 3).
Either P is 3 or less, or it is more than three. The sum of the probabilities of these outcomes is 1. So
We want P(X > 3). So
In which
Then
P(More than 3) = 0.1611
