We can re-group them to add more easily.
300 + 400 = 700
42 + 16 = 58
700+58 = 758
Answer: 758

Answer:
3 and 3/5
Step-by-step explanation:
5/6 divided by 3/1 is the same as 6/5 times 3/1 so,
18/5=3and3/5 as the answer
Answer:
x = 3 sqrt(2)
Step-by-step explanation:
x -√2=√8
Add sqrt(2) to each side
x - sqrt(2) + sqrt(2) = sqrt(8)+ sqrt(2)
x = sqrt(8)+ sqrt(2)
Rewriting sqrt(8) as sqrt(4) sqrt(2) = 2 sqrt(2)
x = 2 sqrt(2)+ sqrt(2)
x = 3 sqrt(2)
Answer: Cluster Sampling
Step-by-step explanation:
In cluster sampling, researcher divides the population into groups ,which are called clusters. Then random sample of clusters are chosen ,and researcher conduct study to collect data about the population.
Here each bus is considered a cluster ,because busses are selected at random ,this sampling would be an example of cluster type of sampling.
