3/2 We look for a number that goes into both 9 and 6 without leaving a remainder, and that number is 3
2. random samples are the least biased samples.
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
Explanation:
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.
The answer is 227/25, first you add and subtract the similars (14-8+3 = 9). 9+8% is the new equation, 8/100 to get rid of a percentage, now it’s 9+8/100 = 227/25
