The equation of a circle in standard form is
+
=
where (a , b) are the coordinates of the centre and r is the radius
The centre is at the midpoint of the endpoints and the radius is the distance from the centre to either of the 2 endpoints
Using the midpoint formula
midpoint = [(x

+
where (,
=(3,8) and (
,
=(-7,2)
centre = ((3-7),
(8+2)) = (-2,5)
Calculate r using the distance formula
r = √(-
)²+(
-
)²)
= √((3+2)²+(8-5)²) = √(25+9) = √34 ⇒ r² =(√34)² = 34
equation of circle is : (x+2)²+(y-5)² = 34
Answer:
outcomes for this sample space (under some considerations)
Step-by-step explanation:
Let's define the multiplication principle.
If a first part of an experiment can happen in n1 ways, a second part of an experiment can happen in n2 ways , . . . , a i - part of an experiment can happen in ni ways, then the total outcomes for the all the experiment are
(n1) x (n2) x ... x (ni)
In this exercise n1 = domestic
n1 is the total classes for domestic category
(Let's suppose n1 = 3 because of Chevrolet, Ford and Chrysler)
n2 = 1 (Also supposing we only have ''a Toyota built in Japan'' category for n2)
n3 = 1 (Also supposing we only have ''A Toyota built in Kentucky'' category for n3)
n4 = 4 (Also supposing we only have ''sedan,hatchback, truck or SUV'' category for n4
The possible outcomes for one person in the experiment are
Where what it is brackets are the possible categories for that classification.
We have 20 different people then are the possible outcomes sample space
In the sample space there are outcomes if we consider that we have 3 types of domestic car, 1 type of foreign car built abroad,1 type of foreign car built in the U.S and 4 differents styles for this 20 different people.
