Answer:
y=1/2x+1
Step-by-step explanation:
one dot on the 1 on the y axis
then more one unit up and two units to the left
and then from the first point (0,1) go one unit down
and two to the right. then make the line with the three points
This conversion<span> of </span>720 seconds<span> to </span>hours<span> has been calculated by multiplying </span>720 seconds<span> by 0.0002 and the result is 0.2 </span>hours<span>.</span>
The answer is the last one. Except for the first one, the questions are asking which two line segments are congruent (or equal to each other) in the triangle. Hope this helps :3<span />
1m = 100cm.
so since the ladybug is 2cm.
you divide 2 by 100, which you will get 0.02m (divide by 100 means moving the dot two times to the left. thats why it leaves you 0.02m)
Answer:
The minimum sample size that we should consider is of 60 employees.
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 
.
So it is z with a pvalue of 
, so 
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.
We want our 99 percent confidence interval to have a margin of error of no more than plus or minus 2 minutes. What is the smallest sample size that we should consider?
We need to find n for which 
So
Simplifying by 2
Rounding up
The minimum sample size that we should consider is of 60 employees.
