Answer:
A.
While D is partially correct, A is the way to go, because samples are easier to collect than whole populations. The internet quotes, "It is a much quicker process and is more time efficient." This proves the theory why A is the correct answer.
Answer:
4*3=12
12*4=
3*3=9
9*2=18
18+48=66
Step-by-step explanation:
I do not understand what to do , more explicitly sorry :(
I don't get you but if you transform the equation to it's standard form, it will be
3x+4y=4
First, Multiply each term by 4:
y(4)=-3x/4(4)+1(4)
4y=-12x/4+4
4y=-3x+4
Now add 3x to both sides of the equation:
4y+3x=-3x+3x+4
3x+4y=0+4
3x+4y=4
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
