Answer:
4
Step-by-step explanation:
6+2+4+2+2+7+5+6+3+3=40
40/10=4
Therefore the mean is 4
Answer:
slope is 2
Step-by-step explanation:
slope is m= y2-y1/x2-x1= 19-11/-9+13= 8/4=2
Answer:
1) 
2) 
3) 
Step-by-step explanation:
General form of sin function is

Where A is Amplitude
B is 
C is Mid line
1) Given : A sine function has the following key features
Frequency = 
Period is 
Amplitude= 2
Mid line y= 2
Y intercept (0,2)
This function is NOT a reflection of its parent function of the x-axis
Solution : We put the value in the general form of sin function
A= 2 ,
, C=2


2) Given : A sine function has the following key features
Period = 4
Amplitude = 3
Mid line y = -1
Y intercept (0,-1)
Solution : We put the value in the general form of sin function
A= 3 ,
, C=-1


3) Given : A sine function has the following key features
Period = 
Amplitude = 2
Mid line y = -12
Y intercept (0,-2)
Solution : We put the value in the general form of sin function
A= 2 ,
, C=-2
