Choose any 2 points from the table:
<span>*10----------------------$25
*15----------------------$35
*20----------------------$45
*25----------------------$55
and find the slope of the line. Supposing we focus on
</span>*15----------------------$35
*20----------------------$45
then:
$45-$35 $10
slope = m = ------------- = ---------- = $2/mile
20-15 5
The anwser to your question is 1 and 5/7
Since

, we know that

follows a Poisson distribution with parameter

.
Now assuming

denote the mean and standard deviation of

, respectively, then we know right away that

and

.
So,
Answer:

Step-by-step explanation:


Answer:
12.50y
Step-by-step explanation:
- If 1 ltr=12.50
- what about y ltrs
Therefore, 1 ltr= 12.50
y ltrs=?
you do cross multiplication
hence, 12.50 × y= 12.50y
total cost= sh.(12.50y)
