Answer:
Population = 75,342 households
Sample = 400 randomly selected households
The percentage who live in a single household unit = Parameter
The average of 2.9 person per household of all households in the city = parameter
The $65,000 median family income of all the households in the city = Parameter
Step-by-step explanation:
The population refers to all the entire elements, observations or subject which fits into a particular study. In the scenario above, the entire household in the city of study. That is, the 75,342 households.
The sample is the subset of the population which is a smaller set of observation meant to be representative of the larger population. The sample here is the 400 randomly selected households.
Parameter differs from statistics in that numerical estimates or calculations obtained from the population is called the parameter while the numerical characteristics derived from the sample is called statistic.
Answer:
C) 4 pencils for each student
D) 8 students per team
Step-by-step explanation:
A unit rate is the number of unit of the first type of a quantity corresponding to one unit of the second type of quantity.
That is, if a and b are two quantities,
Then, unit rate of quantity a = x units of 'a' per 1 unit of 'b' or x units of 'a' for 1 unit of 'b'
By the above statement,
The example of unit rates from the given options are,
4 pencils for each student,
8 students per team
M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8
Fill in the m's:
1*10-1*2=8
10-2=8
8=8
Hope this helps :)

Answer:
7z
Step-by-step explanation:
