The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
<h3>What is the litters about?</h3>
Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.

Based on the information given, the interpretation of the confidence level will be that ninety percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who drive their own car to school.
<h3>
What is confidence level?</h3>
A confidence level simply means the percentage of probability that then m confidence interval will contain the true population parameter when the person draws a random sample.
It should be noted that a 90% confidence interval means a range of values that the person is 90% sure contains the true mean of the population.
