Answer:
The correct option is D. No, because a random sample from all customers of the shopping mall was not selected
Step-by-step explanation:
In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.
In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.
As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
Answer:
Answer3. 9.9cm^3
Step-by-step explanation:
First calculate the volume of the whole pencil. Next, calculate the volume of the lead. Last, subtract. Take away the volume of the lead from the volume of the pencil:
VolWood =
VolPencil - VolLead
First, Volume of the pencil:
vol = pi•r^2•h
= 3.14•(.4)^2•21
= 10.5504 cm^3
Next, volume of lead:
vol = pi•r^2•h
= pi•(.1)^2•21
= .6594cm^3
Last, subtract:
VolWood =
VolPencil - VolLead
= 10.5504 - .6594
= 9.891
~= 9.9cm^3
The volume of the wood is 9.9cm^3.
Answer: D. 4x2-9x-5=0
Step-by-step explanation:
yes everybody will have a site because the total seat is 600 so 450 people can find a place to seat.
yes enough meals: 600 time 3 divide by 4 = 450
No dessert: 600 time 5 divide by 8 = 375
