Answer: The percentage is almost 2%
Step-by-step explanation:
Around 50% of live births in the United States are male. The interpretation of this could be 49% or 51% that is 50 plus or minus 1 percent are Male
the remainder are designated female. That is Female = 49% or 51% too.
If many individuals do not fit neatly into either Male or female.
Then the current estimate of the percentage of such births will be around:
+1 - (-1) = 2%
The percentage is almost 2%

Answer:
25
Step-by-step explanation:
2=10
4=10
5=5
speed = distance/time
distance = speed * time
d = st
time up the mountain: t
time down the mountain: 6.6 - t
distance each way: d
Up the mountain:
d = st
d = 80t
Down the mountain
d = st
d = 85(6.6 - t)
The distances are equal, so
80t = 85(6.6 - t)
80t = 561 - 85t
165t = 561
t = 3.4
6.6 - t = 6.6 - 3.4 = 3.2
It takes 3.4 hours up the mountain and 3.2 hours down the mountain.
3.4 hours at 85 mph covers the same distance as 3.2 hours at 85 mph.
3.4 hours * 80 mph = 272 miles
3.2 hours * 85 mph = 272 miles
