Answer:
First, you will need to arrange the data in an ascending order and the median is the middle value.
If the number of values is an even number, the median will be the average of the two middle numbers.
2, 6, 7, 10, 11, 15, 15
The median in this set is <em><u>10</u></em>.

Answer:
vertex = ( -6 , -3 )
focus = 
axis of symmetry = y = -3
directrix = x = 
GRAPH :
We assume you want to find the inverse transform of s/(s^2 +3s -4). This can be written in partial fraction form as
(4/5)/(s+4) + (1/5)/(s-1)
which can be found in a table of transforms to be the transform of
(4/5)e^(-4t) + (1/5)e^t
_____
There are a number of ways to determine the partial fractions. They all start with factoring the denominator.
s^2 +3x -4 = (s+4)(s-1)
After that, you can postulate the final form and determine the values of the coefficients that make it so. For example:
A/(s+4) + B/(s-1) = ((A+B)s + (4B-A))/(s^2 +3x -4)
This gives rise to two equations:
(A+B) = 1
(4B-A) = 0
Answer:
1002
Step-by-step explanation:
171x6=1026
171×2=342
1026-342=684
684+318=1002
