Answer:
The relationship between two variables is positive when _increase in one causes the increase in the other._______
Step-by-step explanation:
in statistics two variables may be associated or not associated. Normally we define variables as x and y.
If change of x does not affect value of y, then we can say there is no relationship between x and y.
Examples are a person Intelligence quotient and height, a vehicle's weight and its speed, etc.
Sometimes one variable affects another.
Examples are no of hours studied and scores obtained.
Exercises done and health condition etc.
If increase of x causes increase of y then the relationship is positive.
Instead if increase of one variable causes decrease of other variable then the relationship is negative
So
The relationship between two variables is positive when _increase in one causes the increase in the other._______

Answer: A. The period is 2pi/b</h3>
Explanation:
The value of 'a' out front in y = a sin(bx) determines the amplitude.
The b term helps us compute the period, which is 2pi/b for sine, cosine, secant, and cosecant functions.
For example, y = 2sin(3x) has an amplitude of 2 and period of 2pi/3
For tangent and cotangent functions, the period would be pi/b.
Y = 3x
Proof:
3(1) = 3
3(3) = 9
5. 9(3) = 27
6. 27(3) = 81
7. 81(3) = 243
The 7th term is 243.
