The anwser is 19 remainder 4
Answer:
Option A)
Confidence interval decreases
Step-by-step explanation:
If we increase the sample size, then,
- The standard error of the interval decrease.
- If the standard error increase, the margin of error of the interval decrease.
- If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.
Thus, the correct answer is
Option A)
Confidence interval decreases
The smaller number is 270 and the largest number is 1635 if the difference between the two numbers is 1365.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let x and y be the smaller number and larger number respectively.
From the question:
y − x = 1365
y = 6x + 15
After solving the above two linear equations:
x + 1365 = 6x + 15
5x = 1350
x = 270
y = 1635
Thus, the smaller number is 270 and the largest number is 1635 if the difference between the two numbers is 1365.
