First, let's calculate the horizontal and vertical components of the wind speed (W) and the airplane speed (A), knowing that south is a bearing of 270° and northeast is a bearing of 45°:
Now, let's add the components of the same direction:
To find the resultant bearing (theta), we can use the formula below:
The angle -86° is equivalent to -86 + 360 = 274°.
Therefore the correct option is b.
Answer:
(22.12, 27.48)
Step-by-step explanation:
Given : Significance level :
Sample size : n= 8 , which is a small sample (n<30), so we use t-test.
Critical values using t-distribution:
Sample mean :
Standard deviation :
The confidence interval for population means is given by :-
i.e.
Hence, the 95% confidence interval, assuming the times are normally distributed.= (22.12, 27.48)
find the slope (-8,10) (8,15)
<h3>Answer:</h3>m =
Use the slope formula
(x2,y1) = (-8,10) , (x2,y2) = (8,15)
m =
m =
