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 B.
Step-by-step explanation:
The given vertices of triangle ABC are (-1, -1), (-1, -5) and (0.5, -5).
We need to find the coordinates of triangle when it is translated two units left.
So, the rule of translation is
Using this rule, we get
The vertices of triangle A'B'C' are A'(-3,-1), B'(-3,-5) and C'(-1.5,-5).
Therefore, the correct option is B.

Answer:
4. A 3. C
Step-by-step explanation:
Answer:
I. 3 green and 1 purple
II. 1 green and 3 purple
III. 3 green and 3 purple
All can be added
Step-by-step explanation:
Initial ratio is green : purple = 10 : 40
= 1 : 4
If we add more of green marbles and purple marbles to the initial one, there will definitely be an increase in the ratio
For instance,
I. 3 green and 1 purple
II. 1 green and 3 purple
III. 3 green and 3 purple
All of them will cause and increase in the ratio.
