Answer:
1/5
Step-by-step explanation:
Slope formula = (y2-y1)/(x2-x1)
((-6)- (-9))/ ((9)-(-6)
(-6 + 9)/ (9 + 6)
3/15
1/5
Answer: Ordinal
Step-by-step explanation:
We know that the ordinal scale is a level of measurement which is used when we are ordering attributes according to their ranks or preferences.
For example : In an exam we arrange position of students as :
First > Second > Third and so on.
Given : A group of women tried five brands of fingernail polish and ranked them according to preference. It means she is arranging the brands in an order .
Thus this is an ordinal level of measurement .
The horizontal distance until the plan flies over the island is 2687.05 feet approximately.
<u>Solution:</u>
Given that, A plane at an altitude of 7000 ft is flying in the direction of an island
An angle of depression is 21 degree from the plane to the island
We have to find what is the horizontal distance until the plan flies over the island
The diagram is attached below
Assume as shown in the diagram
, now we can use the right angle triangle property
![\tan (21)=\frac{\text {distance between plane and point above island}}{\text {height of plane}}](https://tex.z-dn.net/?f=%5Ctan%20%2821%29%3D%5Cfrac%7B%5Ctext%20%7Bdistance%20between%20plane%20and%20point%20above%20island%7D%7D%7B%5Ctext%20%7Bheight%20of%20plane%7D%7D)
![\tan (21)=\frac{\text {distance between plane and point above island}}{7000}](https://tex.z-dn.net/?f=%5Ctan%20%2821%29%3D%5Cfrac%7B%5Ctext%20%7Bdistance%20between%20plane%20and%20point%20above%20island%7D%7D%7B7000%7D)
![\text { Distance between plane and point above island }=7000 \times \tan (21)](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Distance%20between%20plane%20and%20point%20above%20island%20%7D%3D7000%20%5Ctimes%20%5Ctan%20%2821%29)
![=7000 \times 0.38386=2687.0482](https://tex.z-dn.net/?f=%3D7000%20%5Ctimes%200.38386%3D2687.0482)
Hence, the distance between plane and point above island is 2687.05 feet approximately.
