Answer:
D). (1, 0)
Step-by-step explanation:
The parabola opens to the right, so the focus will be to the right of the vertex at (0, 0). The only answer choice with a positive x-value is D.
___
The equation of a parabola with vertex (0, 0) can be written as
y^2 = 4px
where p is the distance from the vertex to the focus. Here, that distance is 1.
the ansewr is x=3 and y=0
first you would do

next you would do

which would then give you answer choice a
Answer:
should look like this
Step-by-step explanation:
equations are y=x and y = -x if needed
The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
<h3>
What is Experimental Probability?</h3>
Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.
Here , Favorable Outcome = 19
Total outcomes = 20
Probability = Favorable Outcome/ Total Outcome
= 19 / 20
= 95%
Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
