Answer:
the distance is 3/4
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
For any angles formula is:
sin(a+b)=sinαcosβ+cosαsinβ
In our exercise :
α=3x β=2x
sin3xcos2x+cos3xsin2x=sin(3x+2x)=sin(5x)
Result is : sin5x
Answer:
The expected sum is $220 and the standard deviation is $65
Step-by-step explanation:
In order to get the expected sum you add the two expected sums you are given
To get the standard deviation you add the two given standard deviations
Answer:
Coefficient of x
Variable
Constant
Step-by-step explanation:
Given
Required
Complete the statements
In 3x, x is the variable; so:
Coefficient of x
In 2(x + 2), 2 is the variable so:
Variable
4 stands alone. So, it is a constant
Constant
