Please help me to find the answer Y=2X 3X+4Y=22 Y=2X 3X+4Y=22 ​
RSB [31]
<h3>System of equations.</h3>

\left\{\begin{array}{ccc}y=2x&(1)\\3x+4y=22&(2)\end{array}\right

Put (1) to (2):

3x+4(2x)=22\\3x+8x=22\\11x=22\qquad|\text{divide both sides by 11}\\\boxed{x=2}

Substitute the value of x to (1):

y=2\cdot2\\\boxed{y=4}

Solution:

\huge\boxed{\left\{\begin{array}{ccc}x=2\\y=4\end{array}\right}

PolarNik [594]

The best sampling strategy would be a stratified sample.

<h3>How are samples classified?</h3>

Samples may be classified as:

  • Convenient: Drawn from a conveniently available pool.
  • Random: All the options into a hat and drawn some of them.
  • Systematic: Every kth element is taken.
  • Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
  • Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.

For this problem, the 4 different brands of the recorders must be considered, hence the buyers should be divided into groups, and a proportion of each group should be sampled, hence a stratified sample should be used.
