Answer: 4.86
Step-by-step explanation: Since <em>n</em> is being divide by 0.9, to get <em>n</em> by itself, we need to multiply by 0.9 on both sides of the equation.
On the right side of the equation, the 0.9's cancel and we have <em>n</em>. On the left side of the equation, we have 0.9 × 5.4 which is 4.86.
Therefore, 4.86 = n.
Answer:
multiplication property of one or identity
Step-by-step explanation:
The ratio of the given legs of ΔFGH is 3:4, so we know this is a 3:4:5 triangle and the hypotenuse is 5/3 times the shortest leg. Then in similar ΔJKL, the hypotenuse will be (5/3)*2.4 m = 4 m. (selection B)
Answer:
The correct answer is D. It is not true that cluster sampling uses randomly selected clusters and samples everyone within each cluster.
Step-by-step explanation:
Cluster sampling is a method of collecting samples and statistical data, by means of which a certain group formed by people, things, events, etc., is taken as a sample, which are not considered individually but as part of a whole, which is in turn a proportional representation of the universality of samples available in the field.
Now, since this type of sampling allows to embrace large groups of sample units, data are not always obtained from all the components of the cluster, but from those necessary to be able to quantify the desired statistics.
