Briefly explain.HINT: Check the accuracy and the precision of each data set.Data Set 1: 2.91, 3.00, 3.50, 2.85, 3.22, 3.15, 3.49, 2.90, 3.27, 3.15Data Set I1: 3.13, 3.22, 3.19, 4.17, 3.21, 2.62, 3.25, 2.80, 2.40, 3.81Data Set I: 3.24. 3.18. 3.22. 3.20. 3.17, 3.23, 3.19, 3.20, 3.16, 3.24Data Set IV: 2.90. 3.00. 2.92. 2.95. 2.93. 2.97. 2.94. 2.99. 2.96, 3.00     Please donot provide solution in image format and it should be in step by step format and provide fast solution

Acre-feet (af) is a unit that some non-scientists unwisely use to measure volume of liquids. By definition 1 acre foot is one foot multiplied by 1 acre. 1 acre is equal to about 4 × 104 ft2 . 1. How many cubic feet are in an acre-foot?

If the walls in a room are 80.2 m2 in area and a gallon of paint covers 15.0 square yards, how many gallons of paint are needed to paint the room? The following equalities should prove useful: 1 inch = 2.54 cm, 1 foot2 = 144 inch2, 3 ft = 1 yard.

The density of ordinary air is 1.19 g/L. What is the mass, in kilograms, of the airin a room that measures 14.5 ft x 16.5 ft x 8.0 ft?(Hint: Density is defined as d= m/v, so you need to find the volume of the roomand solve for the mass in the density equation. Make sure you do the appropriateconversions to carry out your operations. Use the correct number of significantfigures to express your answer).

a.     A painter uses 4.5 litres of paint to cover a wall with an area of 50 m2. Calculate the average rate of paint coverage in m2/L. b     The painter works for 1.5 hours and then rests for half an hour before completing the painting in another hour. Find the average rate at which the painter paints the wall in m2/h.

- Your answer is partially correct. A partly-full paint can has 0.515 U.S. gallons of paint left in it. (a) What is the volume of the paint, in cubic meters? (b) If all the remaining paint is used to coat a wall evenly (wall area = 12.1 m²), how thick is the layer of wet paint? Give your answer in meters. (a) Number i 1.949 (b) Number i 312.1 Units Units m^3 m^2

(a) A pyramid has a height of 465 ft and its base covers an area of 12.0 acres (see figure below). The volume of a pyramid is given by the expression V = 1 3 -Bh, where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = 43,560 ft²) 2294276.22 m³ (b) What If? If the height of the pyramid were increased to 520 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase? 99.95 X %

An Olympic-size swimming pool is 50 m long, 25 m wide, and 2 m deep. In terms of volume, this pool, when full, holds how many kilogallons of water? Use the following equivalences: 1 gallon = 3.8 L     1 kilogallon = 103 gallon      1 L = 103 mL     for water: 1 mL = 1 cm3      1 m = 100 cm   [Numerical Problem: Just write the numerical answer without units. Express your answer to 2 significant figures in standard notation]
