Answer:
a=-3
b=6
Step-by-step explanation:
equation 1: ax+6
equation 2: -3x+b
get the -3 from equation 2 and plug it into equation 1
get the 6 from equation 1 and plug it into equation 2
6×10^-3
Step-by-step explanation:
0.006
Move the point to the front of the first number that is from 1 to 9.
In the question it's 6, so you move it to the front of 6 .
And because it's from back to front it has to have a negative sign in its power
which is going to be
6× 10^-3
where 6=the number from 1 to 9
^ means raise to power or power of
-3= the negative power
Answer:
D) 0.78, 0.029
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
About 78% of the US, population claims that they visit the dentist at least once a year.
This means that 
Random sample of 200 people:
This means that 
Mean and standard deviation of the sampling distribution:
By the Central Limit Theorem
Mean 
Standard deviation 
So the correct answer is given by option D.
