The middle 50% of the data falls between 13 and 31.
The middle 50% of any data set falls within the box of a box-and-whisker plot. This particular box extends from 13 to 31, so this is the middle 50% of the data.
This is the concept of application of trigonometry;
The height of the tree will be given by:
tan theta=opposite/adjacent
theta=65
opposite=h
adjacent= 10
thus;
tan 65=h/10
h=10 tan 65
h=21.45 m
The distance between the dog and the man is x;
the distance of the man to the tree is (x+10) m
this will be given by:
tan 50= 21.45/(10+x)
getting the reciprocal of the expression we get;
1/tan 50=(10+x)/21.45
cross multiplying the above expression we get;
21.45=(10+x)tan 50
21.45=(10+x)1.2
21.45=12+1.2x
1.2x=21.45-12
1.2x=9.45
x=9.45/1.2
x=7.875
We conclude that the distance of the Firefighter and the dog is x=7.875 m

Answer:
=−6x−1
Step-by-step explanation:
Let's simplify step-by-step.
−1−7x+x
=−1+−7x+x
Combine Like Terms:
=−1+−7x+x
=(−7x+x)+(−1)
=−6x+−1
