No. This is not random sampling as the students chose are not chosen at random. Random sampling would be something done where each sample has equal probability of being chosen. Clearly this is not random sampling.
Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
Answer:
bill is 6 george is 36 and mia is 12
Step-by-step explanation:
6 times 6 is 36 and 1/3 of that is 12. hope I did that right.
Answer:
Step-by-step explanation:
Given
The attached probability distribution of x
Required
Find 
To do this, we consider all values of x less than or equal to-3.
So, we have:
From the table:
So, the equation becomes
32,667 that will be in numbers
