To find the total number of tiles that Sarah needs, we need to calculate the area of the square tray and then divide it by the area of each individual tile.

1. First, we find the area of the square tray. Since the side length of the tray is given as 9 inches, the area can be calculated by squaring the side length.
\text{Area of tray} = (\text{side length})^2 = 9^2 = 81 square inches.

2. Next, we find the area of each individual tile. Each tile is a square with a side length of 1 inch, so the area can be calculated by squaring the side length.
\text{Area of each tile} = (\text{side length})^2 = 1^2 = 1 square inch.

3. Finally, we divide the area of the tray by the area of each tile to find the total number of tiles needed.
\text{Total number of tiles needed} = \frac{\text{Area of tray}}{\text{Area of each tile}} = \frac{81 \, \text{square inches}}{1 \, \text{square inch}} = 81 tiles.

Therefore, Sarah needs 81 tiles in total.

ANSWER: 81 tiles

QUESTION l. An investigation has been carried out in a region to know the perception of "citizen insecurity" of its inhabitants. 1,270 people in the region were interviewed, of which 27.1% responded that it was a "serious" problem. Knowing that this opinion was previously held by 25.3% of the population of that region, we want to know if said opinion has changed significantly for a confidence level of 97.2%. Taking this statement into account, the following is requested: a) Critical value of the contrast statistic. b) Solve the hypothesis test and indicate what conclusion we can reach. c) P-value of contrast.
Imagine that you are in an electronics store and you want to calculate the final price of a product after applying a discount.

25) Paulo saves R$250.00 per month and keeps the money in a safe in his own home. At the end of 12 months, deposit the total saved into the savings account. Consider that, each year, deposits are always carried out on the same day and month; the annual yield on the savings account is 7%; and, the yield total is obtained by the interest compounding process. So, the amount that Paulo will have in his savings account after 3 years, from the moment you started saving part of your money monthly, it will be A) R$6,644.70. B) R$ 9,210.00. C) R$ 9,644.70.
