2 goes into 25 twelve whole times. At that point, the 25 is not quite full,
but there's only enough room in it for 1 more, so you cannot stuff another
whole 2 into it.
Answer:cost of earring=$160
cost of dress= $960
cost of coat =$2,080
Step-by-step explanation:
Let cost of earring be represented as x
so that the cost of dress =6x
And the cost of coat =13x
Since the three items cost a total of $3200, we can develop an equation which can be represented as
cost of earring+cost of dress +cost of coat =3200
x +6x+13x=3200
20x =3200
x=3200/20=160
THerefore cost of earring=$160
cost of dress= 6x =$160 x 6=$960
cost of coat = 13x = $160 x 13=$2,080
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
