That expression is written like so:
(5 + d)/(12 - w)
Answer:
The variable Y represents the number of meters of string in the third yoyo
Step-by-step explanation:
In this equation y stands for the unknown variable. The equation tell you that hope made 3 different yo-yos so the number of yo-yos hope made isn't unknown, meaning, it cant be the first answer. The problem also tells you that hope used a total of 4 meters of string which means that the total number of string used isn't the unknown variable. The number of meters of string in the third yo-yo is the only number that isn't. This makes the number of sting used in the third yo-yo the unknown variable, making it y.
The correct answer would be B because it is is written in correct simplified format
Answer: Cluster Sampling
Step-by-step explanation: Sampling is the process of collecting a representative of a particular Population of persons, activities, materials etc in order to use them for an experiment or research. Sampling can be done in different ways which include Cluster Sampling, random Sampling, stratified Sampling etc.
The activities of the Pollster using a random number to choose the residents of a given location is a Sampling method by Clustering.
Cluster Sampling is the process of identifying the cluster of participants representing the population and their inclusion in the sample group.
