Answer:
The type of sample is Stratified sampling.
Step-by-step explanation:
Consider the provided information.
Types of sampling.
- Random sampling is similar to placing the name of everyone in a hat and pulling out a few names.
- In Systematic sampling, we list of elements is counted off. 
- Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.
- In Cluster sampling, we divide the population into groups, usually geographically. 
- In Stratified sampling we divide population into groups called strata. but this time population might be separated into males and females.
Here the population is divided into groups of males and females therefore it is stratified sampling.
Hence, the type of sample is Stratified sampling.

An equation typically has a slope. Since there is no equation given, I am assuming that 1/7 is the slope:)
1/7 simplified into decimal form is is 0.1428!
        
             
        
        
        
Answer:
see below (I hope this helps!)
Step-by-step explanation:
41. √20 = √4 * 5 = √4 * √5 = 2√5
43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.
45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x
47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.
