D is the answer of your question
Answer:
A would be 13
So the full point would be (13,-3)
You've got 3 values there.
Get the sum of 65, 30 and 25 and divide their sum by the number of values that exist, which in this case is 3.

Answer:
40
The range is all real numbers.
The function given simplifies to just f(x) = 4x.
This is just a straight line that is increasing from left to right. If we reflect the line over the x-axis, it is still a line that goes on forever in each direction.
Therefore, the range will be all real numbers.
Answer:
Probability of selecting one volcano in the world on which to conduct an extensive study is given by

Step-by-step explanation:
Since we have given that
Number of cinder cone volcanoes = 13
Number of shield volcanoes = 18
Number of strato volcanoes = 6
Total number of volcanoes is given by

So, Probability of getting one volcano in the world on which to conduct an extensive study is given by

Hence, Probability of selecting one volcano in the world on which to conduct an extensive study is given by
