Answer: There are 60 blueberries .
Step-by-step explanation:
Given : The ratio of blueberries to strawberries is 2:7
i.e. ![\dfrac{\text{Quantity of blueberries}}{\text{Quantity of strawberries}}=\dfrac27](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BQuantity%20of%20blueberries%7D%7D%7B%5Ctext%7BQuantity%20of%20strawberries%7D%7D%3D%5Cdfrac27)
If Quantity of strawberries = 20
Then,
![\dfrac{x}{210}=\dfrac27\\\\\Rightarrow\ x=\dfrac27\times210\\\\\Rightarrow\ x= \dfrac{2}{7}\times210\\\\\Rightarrow\ x= 60](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B210%7D%3D%5Cdfrac27%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac27%5Ctimes210%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%20%5Cdfrac%7B2%7D%7B7%7D%5Ctimes210%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%2060)
Hence, There are 60 blueberries .
Answer:
cluster sampling
Step-by-step explanation:
ideal groups of objects are naturally chaos arranged in groups, and randomly selected. Unlike class sampling, with homogeneously arranged groups and only a few randomly selected objects from each group, in cluster sampling, each group is allocated in a chaotic and all objects in the group become part of the sample.
