Given that <span>Liza
needs a total of 22.23 square feet of terry cloth to make a beach towel
and a beach bag and the beach bag requires 5.13 square feet of cloth, then the amount of cloth required to make the beach towel is given by
22.23 - 5.13 = 17.1 square feet.
From the figure, given that the width of the beach towel is 3 feet, then the length of the beach towel is given by
17.1 ÷ 3 = 5.7 feet

Answer:
Step-by-step explanation:
You have what is called "perfect squares" so you can use the "difference of squares formula to factor:
So,
you can work the equation backward now and you will get your original equation.
The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
