Comparing map distance to real distance we get 2cm/4km. That means 1cm = 2km.
So the map distance is half the real distance (well, technically not as one is in cm and the other in km but it’s enough to think this way) and a real distance of 10km must mean a map distance of half that (again ignoring the units) so we get 5cm.
Answer:
x=20⁰
Step-by-step explanation:
The angle 6x is next to a 3x one.
And 6x+3x=180⁰
9x=180⁰
x=20⁰
Answer:
A) No
B) No
C) Yes
Step-by-step explanation:
A) 2 out of three observations is equal to
2/3 = 0.67 or 67 %
We know tha the interval
[μ - σ/2 , μ + σ/2] is approximately 68.3 % of the values
Therefore 2 out of 3 would not fall in that interval
B)
4 out of 5 is 4/5 = 0,8 or 80 % If we examine the interval
[μ - σ , μ + σ ] which is approximately 95. Then value 4/5 ( 0,8)
Therefore 0,8 is out of the interval
C) 19/20 = 0,95 or 95 % is almost exact the value for the interval
[μ - 1.5σ , μ + 1.5σ ] That value is inside μ - 2σ , μ + 2
Answer:
In the mid-19th century, the quest for control of the West led to the annexation of Texas and the Mexican–American War. ... This expansion led to debates about the fate of slavery in the West, increasing tensions between the North and South that ultimately led to the collapse of American democracy and a brutal civil war.
