c square
its making me write 20 more characters
ignore this
the answer is c squared
a(n) = a+(n-1)d
here, a = 95, d= 90-95 = -5
a(n) = 95+(n-1)-5
a(n) = 95+5-5n
a(n) = 100-5n ......it's your answer
Answer:
I am assuming yes, the information in the text does not include the prices for each individual item, but when you multiply and add the numbers together ( 12+18(12)+12(12)+ 14(12)= 540) you end up with a lesser number.

Answer:
Proportionate Stratified Random Sampling.
Step-by-step explanation:
Sampling is the process of selecting a small group representative of population.
Stratified Random Sampling is used when population is too heterogeneous, ie too dissimilar. This method includes dividing population into various dissimilar groups [stratas] , similar within themselves. Then, sample is taken from each strata (group), making it good representative of population variety.
If sampling structure is such that - sample units are selected from each strata, in proportion to the strata's presence in population - It is called Proportionate Stratified Random Sampling.
Eg : Dividing population in gender (men, women, other) stratas & taking sample from each strata - in proportion to particular gender in population
