Answer:



Step-by-step explanation:
For this case we have a confidence interval given as a percent:

If we express this in terms of fraction we have this:

We know that the confidence interval for the true proportion is given by:

And thats equivalent to:

We can estimate the estimated proportion like this:

And the margin of error can be estimaed using the fact that the confidence interval is symmetrical

And then the confidence interval in the form desired is:

Answer:
6.7 I think

The area of the whole pizza must be at most 113.10 square inches in order to perfectly fit in the box. The values of r represent the half of the length of the pizza with respect to its center. In this case, the r must not exceed 6 inches (r ≤ 6 inches) in order to fit in the pizza box. On the other hand, the values of a represent the total area the pizza will occupy. In this case, the a must not exceed 113.10 square inches (a <span>≤ 113.10) </span>in order to house the pizza perfectly.
Answer:
let us assume the 3 digit number be 984
To check weather the number is divisible by 3 and 4 then when should know the divisibility rule of 3 and 4.
A number is said to be divisible by 3 when the sum of each digit of the number is divisible by 3. Example 9+8+4 = 21 is divisible by 3 hence the number is divisible by 3.
A number is said to be divisible by 4 when the last two digit is divisible by 4 like 84 is divisible by 4 hence 984 is divisible by 4.
