Answer:
D. None of the choices are correct.
Step-by-step explanation:
Systematic sampling refers to a method of random sampling during which sample members are extracted from a larger population and then collecting corresponding observations using a constant interval between samples taken. This interval, called the sampling interval, is measured by deducting the size of the population by the required sample size. As per the question, the store manager asks every 25th person about the sales which is a classic example of systematic sampling.
Answer:
no solution
Step-by-step explanation:
1/2 = 2/3
This is not a true statement. If you get this after solving an equation, there is no solution to your equation.
Answer:
A
Step-by-step explanation:
Here, we want to write the final formula for the equation after performing the given transformations
Reflection on the y-axis means the x-axis value will change sign
that will give:
y = -x^1/3
Transition of 3 units in the positive x axis
mathematically, we are adding 3 to x
so we have
y = -(x+3)^1/3
4 units in the negative y direction means we are subtracting 4 from the whole equation
That means;
y = -(x + 3)^1/3 - 4
This shows that the first option is right
