Answer:
See below
Step-by-step explanation:
The given equation is
Given
Distributive Property
Addition property of equality;
Division property of equality.
Given parameters:
Number of hours worked by Peter = 6.5hrs
His friend Joseph works 
hours more than Peter;
Unknown:
Number of hours Joseph can work more than Peter = ?
This problem is pretty straight forward.
We see from the given parameters, it was explicitly stated that Joseph, the friend of Peter works more hours .
Therefore, Peter's friend worked more hours.
Answer:
102 1/3 swimmers
Step-by-step explanation:
Let
Number of swimmers on Tuesday = x
Number of swimmers on Monday = 2x
Number of swimmers on Wednesday = 3x - 11
Total swimmers for all 3 days = 625
x + 2x + (3x - 11) = 625
3x + 3x - 11 = 625
6x = 625 - 11
6x = 614
x = 614 / 6
= 102 2/6
x = 102 1/3 swimmers
Number of swimmers on Tuesday = x = 102 1/3 swimmers
Number of swimmers on Monday = 2x
= 2(102 1/3)
= 204 2/3
Number of swimmers on Wednesday = 3x - 11
=3(102 1/3) - 11
= 307 - 11
= 296

Answer: inferential
Step-by-step explanation: inferential statistics help us to make predictions ( that is, inferences) from that data. With inferential statistics, you take data from samples and make generalizations about a population.
Also, inferential statistics allow us to reach conclusions that extend beyond the immediate data alone
In this question, the survey reports on a sample of the country's population that make an inference to the population. It is therefore an inference statement.
