Inverse.
Step-by-step explanation:
Inverse trigonometric functions.
e. g. tan-1 x means 'the angle whose tangent is x'.
They are also called arcsin, arccos and arctan.
Answer: the second one i may be wrong but i can relate to you ❤
Answer:
Statement D is correct.
Step-by-step explanation:
Solution:
Data Given:
Linear Regression Relationship = Speed = 10.3 + 5.4 (hour)
Linear Regression Relationship = y = mx + c
Here,
m = slope = 5.4
c = 10.3 = y - intercept
The correct Answer is D)
Because:
As, the residual value is positive, it means the typist attained faster speed than the model predicted. As we know, residuals is the result of difference between predicted values of the model and data values. On the contrary, if residual would be negative then we would say that typist speed is slower than the model predicted.
Hence, Statement D is correct.
