Answer:
One unique triangle
Step-by-step explanation:
this is the answer to this question - Two weather tracking stations are on the equator 146 miles apart. A weather balloon is located on a bearing of N 35°E from the western station and on a bearing of N 23°E from the eastern station. How far is the balloon from the western station?
Answer:
Reasons:
The given parameters are;
Distance between the two stations = 146 miles
Location of the weather balloon from the Western station = N35°E
Location of the weather balloon from the Eastern station = N23°E
The location of the station = On the equator
Required:
The distance of the balloon from the Western station
Solution:
- The angle formed between the horizontal, and the line from the Western station
to the balloon = 90° - 35° = 55°
- The angle formed between the horizontal, and the line from the Eastern station
to the balloon = 90° + 23° = 113°
The angle at the vertex of the triangle formed by the balloon and the two stations is 180° - (55 + 113)° = 12°
By sine rule,
Distance from balloon to western station = 146/sin(12 dg) = Distance from balloon to western station/sin(113 dg)
Therefore;
Distance from balloon to western station = 146/sin(12 dg) x sin(113 dg) ~ 646.4
Step-by-step explanation:
Answer:
Z=11.0
Step-by-step explanation:
Let Caucasian individuals be the population 1 and African American be the population 2. So, we are given that
n=150
n1=75
mean1=xbar1=6.1.
standard deviation1=S.D1=σ1=1.1.
Variance1=V(x1)=σ1²=1.1²=1.21.
n2=75.
mean2=xbar2=4.3.
standard deviation2=S.D2=σ2=0.9.
Variance2=V(x2)=σ2²=0.9²=0.81.
The z-statistic is
Z=10.97
Z=11.0
So, the z value obtained while calculating the test statistic is approximately 11.0.
