Answer:
Stratified random sampling.
Explanation:
Startified random sampling is one that divides the total population into subpopulations and analysis of each subpopulation is done to measure variations between them.
Each subpopulation is adequately represented in the whole sample used for study. For example when a population bis divide based on age into 18-30 years, 31-50 years, and 51 years and above.
The researcher divides all the current students into groups based on their class standing (freshman, sophomores, etc.). Then, she randomly draws a sample of 50 students from each of these groups to create a representative sample of the entire student body in the school.
This is use of stratified random sampling.

Implied warranty of trade usage
Explanation:
An implied warranty for a good is defined as the assumption on the part of the buyer that a product that is purchased should perform at a minimum acceptable level.
For example when a television is purchased it is assumed that it will come on.
An implied warranty of trade usage requires a seller to disclose any traits or conditions that will result in a product being defective.
In the given instance the delivery to Salma did not have packaging in a bubble wrap within a carton box that has the signs for "fragile," "this way up," and "caution" on it.
This is a breach of implied warranty of trade usage.
Answer:
We are going to pay $892.137 or less for the bonds.
Explanation:
We need to calculate the present value of the bond at 11% interet rate
Cashflow from the bond:
Principal x interest = interest service
1,000 x 9.5% = 95
Present value of annuity of 95 during 15 year at 11%
Present value of the interest service 683,1326097
Second we have to calculate the present value of the 1,000 principal in 15 years
209.0043467
Finally we add both together for the present value fothe bond at our rate
209.0043467+ 683,1326097 = 892.1369564 = 892.137
