Given:
The function is:
To find:
The result of the operation .
Solution:
If , then the graph of f(x) is reflected across the x-axis to get the graph of g(x).
We have,
The given operation is:
So, it will result in a reflection across the x-axis.
Therefore, the correct option is A.
Answer:
option (a) It will be closer to 30 than to 20
Step-by-step explanation:
Data provided in the question:
For sample 1:
n₁ = 10
variance, s₁² = 20
For sample 2:
n₂ = 15
variance, s₂² = 30
Now,
The pooled variance is calculated using the formula,
on substituting the given respective values, we get
or
= 26.0869
Hence,
the pooled variance will be closer to 30 than to 20
Therefore,
The correct answer is option (a) It will be closer to 30 than to 20
