Researchers are performing a study of what type of ice cream shoppers want. They're looking at the tenth person who goes to the shop, and every fifth person after that. This type of sampling is referred to as a random sampling.
Answer:
Area = 113.04 m²
Step-by-step explanation:
Area of a circle:
If we are told to use 3.14 for pi we can now make a new equation:
Area = 3.14×6²
Area = 3.14×36
Area = 113.04m²
Answer:
Step-by-step explanation:
Parallel lines share the same slope.
In the given 4x - 2y = 4, the first 4 (the coefficient of x) and the -2 (the coefficient of y) determine the slope; all lines parallel to 4x - 2y = 4 have equations which are identical to 4x - 2y = 4 EXCEPT that their constants (in this case 4) differ.
4x - 2y = 0
4x - 2y = -3
4x - 2y = 7
constitute a set of parallel lines.
If we reduce 4x - 2y = 4 to 2x - y = 2, the second equation has the same slope AND same y-intercept as does the first.
