Answer: 4 and 1/4
Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.
So to find the mean of the data set shown here, let's begin by adding the numbers.
34 will be divided by how many numbers are in the set which is 8.
34 ÷ 8 = 4.25
To write 4.25 as a fraction, we can first write 4.25 as a fraction with 1 in the denominator.
Now, we can multiply 4.25/1 x 100/100 in order to remove the 2 decimal places. Once we multiply the numerator and denominator by 100/100, we get the fraction 425/100.
Now, we can reduce 425/100 by dividing both the numerator and denominator by the greatest common factor of 425 and 100 which is 25.
425 ÷ 25 = 17
100 ÷ 25 = 4
17/4 can be written as the mixed number 4 and 1/4.
Here is the graph, it's just a line.
The square meters of the area the oil slick will cover is 9.6 × 10⁶ m².
<h3>What is meant by volume?</h3>
Volume is defined as the amount of three-dimensional space enclosed by a closed surface.
- The liter (L) is the metric system's base volume unit, with several extended volume units also available.
- There are also many metric volume units based on the a cubic length dimension, including such cubic meters or cubic centimeters. Gallons and ounces are examples of imperial volume units.
Now, as per the given question;
First, we determine the entire volume of oil in gallons by multiplying the volume per barrel even by total number of barrels:
15×42 gal = 630 gal
This volume must be converted to square meters:
V = 630 gal × (0.00379 m³/ gal
V = 2.4 m³
The thickness (height) of a oil film in meters is required:
h = 250 nm × (m/10⁻⁹nm)
h = 2.5 × 10⁻⁷m
The surface area of a oil film is calculated by dividing the oil volume by height of the oil film.
A = V/h
A = 2.4 m³/2.5 × 10⁻⁷m
A = 9.6 × 10⁶ m²
Therefore, the area of the oil slick cover is found to be 9.6 × 10⁶ m².
