First Question
A is not correct. If you have one point, you wouldn't know where the line would extend. You need at least two points to determine a line. You need at least three points if you don't know if the line is linear.
B is correct. A ray has one endpoint and extends infinitely in one direction.
C is not correct. A line segment has two endpoints and does not extend infinitely.
D is not correct because a line is infinitely extending. It has no endpoints.
Second Question
A is not correct. Skew lines are two or more lines that do not intersect, are not parallel, and are not coplanar.
B is correct. Perpendicular lines must intersect at a right angle.
C is not correct. Two parallel lines can lie in the same plane.
D is not correct. A transversal is a line that intersects two or more other lines. This does not have to be four other lines (but it can).
Answer:
Step-by-step explanation:
If 1 inch = 3 units,
Therefore 1 unit = ⅓ inches, so to answer your question we have to
Multiply it by 20, to have :
20 units = 20× ⅓ = 20÷3
20 units = 6.66
Therefore we can use the same principle in that of 14 units.
14 units = (14 × ⅓) inches
14 units = 4.66 inches

Answer:
-32+(-4+7)*2= -32+(-8+14)= -32-8+14= -40+14= -26
Step-by-step explanation:
Answer:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
Step-by-step explanation:
Given that a random sample of 311 medical doctors showed that 135 had a solo practice.
Sample proportion = 0.43
Std error of sample proportion =
Margin of error 90%
Margin of error in percent = 4.6%
Hence correction option is:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
