Answer:
10
Step-by-step explanation:
11, 13, 4, 9
In order to find the median we must first arrange the numbers in order (Least to greatest)
4, 9, 11, 13
If there is 2 numbers in the middle: the median is their average
If there is only one number in the middle, that number is the median.
Since there are two numbers (9 and 11) we have to take their average.
(9+11) / 2 = 20 / 2 = 10
The median is 10!
Step-by-step explanation:
We split the duration into 2 smaller intervals.
- 8:45p.m. to midnight = 3 hours and 15 min
- Midnight to 2:15a.m. = 2 hours and 15 min
Hence the total duration is 5 hours and 30 min.
Answer: Third answer
Step-by-step explanation:
The answer is True.
Explanation:
Let a = major axis
Let b = minor axis
Let c = focal length.
Consider the right focus, located a distance c from the center of the ellipse (at the origin).
From the right focus to the right point on the major axis is equal to a-c. This is the minimum distance.
From the right focus to the left point on the major axis is equal to a+c. This is the maximum distance.
0=x3-3x2
x3-3x2=0
x2•(x-3)=0
x=0
