Step-by-step explanation:
Mid Point : A point which lies on the line segment and is equidistant from both the ends of the segment is called a mid point.
A line segment can have ONLY ONE mid point and it divides the line segment into two equal parts.
Now, Given : C is the midpoint of AB.
and B is the midpoint of CD.
⇒ AC = BC and BC = BD
Now by Euclid's Lemma
- "Things which are equal to the same thing are equal to each other."
Here, AC = BC , and BC = BD
⇒ AC = BD
Hence the result.

Step-by-step explanation:
If we count for both numbers up to 36, we start seeing a pattern...
Candy: 6 12 18 24 30 36
Danny: 4 8 12 16 20 24 28 32 36
Every other number in Candy's counting is also counted by Danny. So here's what we'll do:
600/6 = 100
This is how many numbers Candy counted overall.
100/2 = 50
This is how many numbers Danny counted that were also numbers Candy counted.
Answer:
50 of the numbers that candy counted were also counted by Danny.
Answer:
100 students should be surveyed in order to cut the width of the interval down from 3 hours to 1.5 hours
Step-by-step explanation:
Given that a 95% confidence interval, based upon a sample of size 25, for the mean number of hours of sleep that college students get per night was 5 to 8 hours.
Confidence interval = (5,8)
This implies that mean = 6.5 and margin of error = 1.5
i.e.
If the interval width to be cut into half then the
New confidence interval = (5.75, 7.25)
Margin of error = 0.75
This is possible only when new n= 100
Hence sample size should be increased to 100
100 students should be surveyed in order to cut the width of the interval down from 3 hours to 1.5 hours
