Step-by-step explanation:
As given
A blimp provides aerial television views of a tennis game.
The television camera sights the stadium at a 17degrees angle of depression. The altitude of the blimp is 400m.
Now by using the trignometric identity .

As the figure is given below .
Perpendicular = AC = 400 m
Hypotenuse = AB

Putting all the values in the identity .



AB = 1379.31 meters
Therefore the 1379.31 meters is the line-of-sight distance from the television camera to the base of the stadium .

Consider the provided information.
On the Math exam, the mean was µ = 30 with s = 5, and Sarah had a score of X = 45.
Z score for Math: 



On the Spanish exam, the mean was µ = 60 with s = 8 and Sarah had a score of X = 68.
Z score for Spanish: 



On the English exam, the mean was µ = 70 with s = 8 and Sarah had a score of X = 70.
Z score for English: 


We can observe that Z score of Math is greater than Spanish and English.
Which means that Sarah did the best in her Math exam.
Hence, Sara expect the better grade for Math class.
