Answer:(
gof) = 12x+8
Step-by-step explanation:
to find gof plug f into g :
(g o f) = 6(2x+1)+2
then simplify:
( g o f) = 12x+8
When you solve for y the answer would be y=-2x+4 coz in order to get or solved the y you need to divide 12 to 6 and so on and so forth transposed the 2x+4 and then the answer would be
y=-2x+4
Answer:
Margin of error of 0.0485 hours.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
That is z with a pvalue of , so Z = 1.96.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
In this question:
The margin of error is of:
Margin of error of 0.0485 hours.
