- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
r = 4s
r = 1/2s + 7
<u>Step 2: Solve for </u><em><u>s</u></em>
<em>Substitution</em>
- Substitute in <em>r</em>: 4s = 1/2s + 7
- Subtract 1/2s on both sides: 7/2s = 7
- Divide 7/2 on both sides: s = 2
<u>Step 3: Solve for </u><em><u>r</u></em>
- Define equation: r = 4s
- Substitute in <em>s</em>: r = 4(2)
- Multiply: r = 8
Answer:
so here tje answer is
50 <em>/</em><em> </em><em>1</em><em>0</em><em> </em><em>=</em><em> </em><em>-</em><em>k</em><em> </em>
<em>s</em><em>o</em><em> </em><em>the</em><em> </em><em>v</em><em>a</em><em>l</em><em>u</em><em>e</em><em> </em><em>o</em><em>f</em><em> </em><em>k</em><em> </em><em>=</em><em> </em><em>5</em>

I would say a but not 100% sure.
Answer: Cluster sampling.
Step-by-step explanation:
- Cluster sampling is a sampling technique in statistics in which the researcher splits the entire population into different groups called clusters.
- After that he randomly select a sample from the clusters from the population and survey all elements of sampled clusters.
- Researcher performs his analysis on data from the sampled clusters.
In the given situation Greyhound Lines randomly selects 90 buses during a certain week and surveys all passengers on the buses.
Here, week= Cluster
Buses = Elements
Therefore , the type of sampling is used = Cluster sampling.
