<h3>
Answer: C) 3 gallons</h3>
==========================================================
Explanation:
1 inch = 1.5 feet
10 inches = 15 feet (multiply both sides by 10)
6 inches = 9 feet (multiply both sides of the first equation by 6)
The scale drawing is 10 inches by 6 inches, which corresponds to real life dimensions of 15 ft by 9 ft.
The area of the one wall is 15*9 = 135 square feet.
There are four identical walls of equal area, so 135*4 = 540 square feet is the total area we need to paint.
--------------------------------------------------
1 gallon = 250 square feet
0.004 gallon = 1 sq ft (divide both sides by 250)
2.16 gallon = 540 sq ft (multiply both sides by 540)
You'll need exactly 2.16 gallons of paint to cover all four walls.
Since Caleb cannot buy 0.16 of a gallon, he'll need to buy an additional gallon to cover the fractional portion. So he'll need to buy 3 gallons of paint and he'll have 3-2.16 = 0.84 gallons of paint left over.

The answer is 24! You can find this out by just counting them.
If they meant 10 sets of push-ups, then she did 45. if they just meant 10 push-ups, it is 25.

Answer:
For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.
But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
Then the best answer is:
2. False
