Answer:
16
Step-by-step explanation:
For x=5 y=4 so we can calculate the slope m=(y1-y)/(x1-x)=(5-0)/(4-0)=5/4
then use (y-y1)=m(x-x1) and you get
y=(5/4)x-5
15)
4(a+b) + 12
= 4a + 4b + 12
= 4(a +b + 3)
answer is
b) 4(a +b + 3)
16)
x - 4(2x + 2)
= x - 8x - 8
= -7x - 8
answer
-7x - 8
Answer:

Step-by-step explanation:
Required
The population standard deviation
First, calculate the population mean

This gives:



The population standard deviation is:

So, we have:
