Answer:
4 is the answer to your question
Step-by-step explanation:
Answer:
center point: (-4, 2)
radius: 8 units
Step-by-step explanation:
To find the radius of a figure in a coordinate plane, you have to do x-y where x is the starting point and y is the ending point. so in this case:
-4-(-12)
= -4+12
= 8
P(B|A) means "the probability of B given A", which in turn means: how likely is B, if we are guaranteed that A is true?
In your case, this means: if you already know that the person has a sister, how likely it is that the same person also has a brother?
if you look the diagram, you see that 4 people has a sister: Davis, Kari, Chu, Evan. Out of these 4 people, 2 of them also have a brother.
This explains P(B|A)=0.5: half of the people with a sister also have a brother.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is the equation of a vertical parabola open up
The vertex is a minimum
Convert to vertex form
Complete squares
Factor the leading coefficient
Rewrite as perfect squares
The vertex is the point (-1.5,-1.5)
Find the zeros of the function
For y=0
square root both sides
Find the y-intercept
For x=0
The y-intercept is the point (0,3)
therefore
The graph in the attached figure
