The following is an example of a cluster sampling.
Cluster sampling<span> is a </span>sampling<span> technique used when "natural" but relatively heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this technique, the total population is divided into these groups (or </span>clusters) and a simple randomsample<span> of the groups is selected.</span>
5w²-3w-2=0
5w²-5w+2w-2=0
5w(w-1)+2(w-1)=0
(5w+2)(w-1)=0
either w= -2/5 or w=1
Answer:
Maximum number of children among whom 32 red marbles, 144 blue marbles and 176 green marbles can be divided equally is 16.
Step-by-step explanation:
Finding HCF of 32, 144, 176
32 = 2 * 2 * 2 * 2 * 2
144 = 2 * 2 * 3 * 2 * 2 * 3
176 = 2 * 2 * 2 * 11 * 2
HCF = 2 * 2 * 2 * 2 = 16
