I'm not sure how many decimal places you need, so there are most of them
Hopefully this helps- let me know if you have any questions
Answer:
Both questions are true.
Step-by-step explanation:
The general mathematical equation of a line can be written as 
.
If we rearrange the two equations given in the question as follows:
and 
We can see that they follow the general equation we defined earlier so we can say that they represents linear lines.
The 
given in the second question also represents a similar linear line with a different slope.
So the two questions are both true.
I hope this answer helps.

Answer:
17000 batteries
Step-by-step explanation:
Three years and one month is equivalent to the mean minus one standard deviation.
Three years and seven months is equivalent to the mean plus one standard deviation.
For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months
