Answer:
Differences between the actual Y values and the predicted Y values.
Step-by-step explanation:
The residuals represent the Differences between the actual Y values and the predicted Y values.
Residual is the difference between the measured value and the predicted value of a regression model. It is important to understand residuals because they show how accurate a mathematical function, such as a line, is in representing a set of data.
Answer:
Option D.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
f(t) = a*sin (b*t +c) + d
Please, see attached picture below.
By looking at the picture with all the possible cases, we can tell that the correct option is D.
The function has a period of T = 6π
Max . Amplitude = 9
Min . Amplitude = -5
Answer:
(-8)(1) = -8
Step-by-step explanation:
The expression that uses utilizes a multiplicative inverse is (-8)(1) = -8
A multiplicative inverse is such that when an identity element such as the number 1 multiplies another, it does not change it in any way.
The expression where we see this is the option C;
(-8)(1) -8 multiplied by 1 does not change -8, it is still -8.
