Greatest common factor is 3
Answer:
D. R(x)=850x+9600
Step-by-step explanation:
Use the given information as points on a line, and find the slope.
The two given points are (10, 18,100) and (20, 26,600).
slope = (difference in y)/(difference in x)
slope = (26,600 - 18,100)/(20 - 10)
slope = 8,500/10
slope = 850
Only choice D. has a slope of 850.
Answer: D. R(x)=850x+9600
Answer:
24.6 < μ < 27.2
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.

The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
The population of the bacteria 96 minutes from now is 12.
Answer:
slope=2
Step-by-step explanation:
slope = y/x
