We can adjust the data by adding 4 to everything before we calculate the statistics.  Or we can calculate the statistics on the given data and just add 4 to everything at the end.  We'll get the same answer either way.
Let's sort the seven data points:  5 5 5 7 7 9 10
Those add up to 48 so the mean is 48/7 = 6.9
The one in the middle is 7 so the median = 7
The mode is the most common one, mode = 5
The range is the difference between max and min, so range = 10 - 5 = 5
In the second week we add four to everything.  Since that adds four to the min and max, the range doesn't change.
Answer: mean=10.9, median=11, mode=9, range=5

Answer:
option f
option a
option d
option c
option e
option b
Step-by-step explanation:
we have x^2 - 6x + 7 = 0
f) x^2 - 6x   = -7     
a) x^2 - 6x + 9 = -7+9
d) (x-3)^2=2
c)
e) x-3=+-
b) x=3+-
