The expression is equal to 3sqrt(517)/5
Answer:
y=5x+10 or y=25 (i'm not sure what they're asking)
Answer:
they are perpendicular
Step-by-step explanation:
because the slope are opposite which means the lines intersect.
Answer:
(a) The sample variance is 16.51
(a) The sample standard deviation is 4.06
Step-by-step explanation:
Given

Solving (a); The sample variance.
First, calculate the class midpoints.
This is the mean of the intervals.
i.e.





So, the table becomes:

Next, calculate the mean




Next, the sample variance is:

So, we have:



The sample standard deviation is:



We use the formula:
Total = Principal * e ^ (rate * years)
Total = 1,500 * e ^ (.03 * 15)
Total = 1,500 * e ^ .45
Total = 1,500 *
