I am guessing vectors :)
(-17, 9)
or in polar form
√370, -27°53'50"
Answer:
D
Step-by-step explanation:
In this question we are asked to pick the correct option that clearly states what statisticians use linear regression for.
To answer this question, I shall be considering the validity of the options one after the other.
But before that , what is a linear regression model?
A linear regression model employs a linear plot to explain the relationship between a dependent variable and another variable called the independent variable.
Option a is wrong.
A regression model does not say if the dependent and independent variables match
Option B is wrong
A linear regression model cannot be used to predict the value of an unknown dependent variable from the unknown Independent variables. X is the independent here with y the dependent
Option C is wrong
Since Y scores is known, then what are we predicting again?
Option. D is correct
We predict values of the unknown dependent variable y from the known independent variable x

The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of right angled triangle.
Let d represent the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:
Angle = 90 - 67 = 23°
Using trig ratio:
tan(23) = d/1143
d = 485.2 feet
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
