Answer:
8
Step-by-step explanation:
Given that in a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10
Mean = 6
Since mean = 6 we get sum of all the 6 scores = 
Now II part says 10 is changed to 20
i.e. original sum = 36
Changed value = 10
Adjusted value =26
Add: new value =22
New sum =48
So we have sum = 48
New mean= 
(This can also be done using the formula
old mean + positive change in one score/6)
i believe this is the answer n(2)-7<span />
11 = C/2-1 + C/2 + C
12 = C/2 + C/2 + C
12 = 4C/2
12 = 2C
C = 12/2
C = 6
Hence, tree A is 2m (3-1), tree B is 3m (6/2) and tree C is 6m
Answer: Choice D) The h(x) values -4, -2, 2, 4, and 6
Explanation:
The range is the set of all possible y outputs, or h(x) outputs.
We simply list the y coordinate of each blue point shown on the graph.
We cannot say something like -4 ≤ h(x) ≤ 6 because there are gaps where the function is not defined. For instance, h(x) = 0 is not possible, so 0 is not in the range. Put another way: there is no point with y coordinate 0 on the graph, so that's why 0 is not part of the range.
