Answer:
Step-by-step explanation:
1) Three points are not in the same plane if and only if exactly one line passes through them.
It is biconditional and false because more than one plane can pass through three points
2)Exactly one line passes through three points if the points are in an infinite number of planes.
It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane
3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
4). three points on the same line if and only if exactly one plane passes through them.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
It's a bit of a bummer to have to work through all of these to find the answer. That a lot of slope calculations (or graphing, or whatever). When there are this many, a spreadsheet or other machine help can make it easier.
The correct choice is the last one, XYZ, with vertex X being where the right angle is located.
_____
Slope of XY is 4/7; slope of XZ is -7/4. The product of these is -1, so those segments are at right angles.
Answer:
Independent event
Step-by-step explanation:
Since the second and third spins do not depend on the results of the previous spins, this is an independent event.
Answer:
5y
Step-by-step explanation:
add like terms
since 4y and y are like terms you can add them to make 5y
