This kind of sampling is called the Cluster sampling. The cluster sampling method is done by dividing the population by groups called clusters. There will be an equal number of samples drawn from each cluster using simple random sampling. In here, the population are the students which are divided into clusters - by year level. 15 students will be selected from each cluster.
The answer is:
<u>y= -0.5x -2.5</u>
<em>you can also write it as:</em>
<u> y = -0.5x + (-2.5)</u>
m = -0.5
b or "c" = -2.5

Answer: 103.75
Step-by-step explanation: hope this helps!
Answer:
because MATH is a rhombus
=> MA = MH = HT = AT
=> y + 10 = 5y - 6
⇔ 4y = 16
⇔ y = 4
with y = 4 => MH = 4 + 10 = 14
but MH = MA
=> MA = 14
