We want to select 3 pairs of people from a group of 6.
We use the formula:
n! / (r! * (n -r)!)
where n = 6 and r = 2
combinations = 6! / (2! * 4!) =
combinations = 6 * 5 / 2
combinations = 15

Answer:
5.5
Step-by-step explanation:
We have a list of 10 numbers (n = 10) ordered from lower to higher.
1 2 3 4 5 6 7 8 9 10
The median is the value separating the higher half from the lower half of a data sample. Since n is even, there is no middle value and the median is defined as the mean between the two middle values, in this case, 5 and 6. Then,
median = 5 + 6 / 2 = 5.5
It should be option A! I hope this helps you!
Answer:
Slope-Intercept Form of a Line (y = mx + b)
Step-by-step explanation:
The slope-intercept is the most “popular” form of a straight line. Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.
3 km north.
the east and west cancel out and the 5 north being greater than the two south leave you to only have to subtract the 2 south from the 5 north
