Answer:320 children and 262 adults swam in the public pool
Step-by-step explanation:
Let x represent the number of children that swam in the public pool.
Let y represent the number of adults that swam in the public pool.
582 people used the public swimming pool. This means that
x + y = 582
The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled to $1004.00. This means that
1.5x + 2y = 1004 - - - - - - - - - -1
Substituting x = 582 - y into equation 1, it becomes
1.5(582 - y) + 2y = 1004
873 - 1.5y + 2y = 1004
- 1.5y + 2y = 1004 - 873
0.5y = 131
y = 131/0.5 = 262
Substituting y = 262 into x = 582 - y, it becomes
x = 582 - 262 = 320
I think the answer is 13.5 square units.
Answer:
H1 : μ < 1225
Step-by-step explanation:
The alternative hypothesis in carrying out a statistical test could be explained as a notion which aims to displace or rival an initial position, the null hypothesis.
When declaring an hypothesis, the statement compares the initial or population mean in the hypothesis statement and not the result or outcome of the sample statistic.
In the scenario above :
The null is of the notion that :
H0 : μ = 1225 ;
Hence, the stance of the alternative which is that the mean is lower or less will be written as :
H1 : μ < 1225
