Answer:
Statistical significance relates to whether an effect exists.
Practical significance refers to the magnitude of the effect.
And you can have statistical significance but not practical.
Step-by-step explanation:
Let's analize it with an example.
Suppose that your new treatment involves hair recovery.
You divide the population of the test in two different groups.
And you apply the treatment to only one of them.
You can see that the treatment works and there is a 3% improvment.
You have statistical significance. The treatment worked.
Now, if the test was expensive, the 3% improvement might not be practical.
Answer:
(0, -4)
Step-by-step explanation:
The coordinates of the points from which the directed line segment extends = (-6, -6) to (9, -1)
The ratio the required point partitions the line = 2 to 3
The formula for finding the coordinate of a point that partitions a line AB into a ratio 'a' to 'b', where the coordinates of, A = (x₁, y₁) and B = (x₂, y₂) is given as follows;

Therefore, the required point is located as follows;

The coordinates of the point is (0, -4)
Answer:
37 & 67
Step-by-step explanation:
11 & 33
42 & 56
- 42 - 1, 2, 3, 6, 7, 14, 21, 42
- 56 - 1, 2, 4, 7, 8, 14, 28, 56
- Both 42 and 56 are composite numbers
- 42 & 56 is incorrect
37 & 67
- 37 - 1, 37
- 67 - 1, 67
- Both 37 and 67 are prime numbers
- 37 & 56 is correct
57 & 97
- 57 - 1, 3, 19, 57
- 97 - 1, 97
- 57 is a composite number, 97 is a prime number
- 57 & 97 is incorrect
A.) -13
b.) 17
c.) 80
d.) 1
All your doing is substituting x for the number in the parenthesis and matching it with the correct function. For example, f(-3) would be 2(-3)-7 which is equal to -6-7 which is -13.
