A perpendicular line can intersect the segment at any point but the perpendicular isector only intersects the segment at its mid-point
Further explanation:
Let us define both terms one by one
<u>line that is perpendicular to a segment:</u>
A line which makes an angle of 90 degrees with another segment is called perpendicular line. A line that is perpendicular to a segment may intersect the segment at any point between the endpoints of the segment.
<u>perpendicular bisector of a segment:</u>
The perpendicular bisector although also makes the angle of 90 degrees with the segment but the perpendicular bisector only intersects the segment at the mid-point of the segment dividing the segement in two equal segments that is why it is called bisector.

Answer:
D
Step-by-step explanation:
if a<b,then b<a is the answer
Your answer would be D you would add up all the days together then just put the clear days together to get 17/30 that then reduces to .57
Answer:
3. It is likely.
Step-by-step explanation:
Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side
<u>Then the areas covered will be as:</u>
- point 20 = πr² = S
- point 15 = π(2r)² - πr² = 3πr² = 3S
- point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
- point 5 = π(4r)² - π(3r)² = 7πr² = 7S
Total area of the dartboard is S+3S+5S+7S = 16S
The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S
The probability of scoring at least 10 points is:
As it is between 1/2 and 1, the probability is in 'likely' region
<u>So the correct answer choice is:</u> 3. It is likely
