Answer:
2.6667yd^3
Step-by-step explanation
Concrete volume is calculated with Length * width * height.
Provided data:
height = 6 inches
To convert to yards:
1 inch = 0.0277778 yards
Thus, 6 inches = 6 * 0.0277778
This gives us 6 inches = 0.1666668 yards
Width = 8 feet
Length = 6 feet
Area = Length * Width = 48ft²
To convert to yards:
1 foot = 0.333333 yards
Hence, 48 feet = 48 * 0.333333
Area in yards squared = 15.999984yd²
Volume = 15.999984 * 0.1666668
Therefore, Volume = 2.6667 yd^3
In conclusion, she will require 2.6667yd^3 of concrete.
To find the solution for the equations, I will note the equation as I restate the original form. A number, n, (n) is summed with 15 subtracted from 3 times itself (+3n -15). The outcome is (=) 101. (101) Now, we will focus solely on what is contained within the parentheses. n + 3n -15 = 101. The properly formatted expression in your answers is: 3n - 15 + n = 101, as your initial response.
2.07. The mean for X is calculated as 1.00, and for Y as 1.07, leading to the total of X + Y = 1 + 1.07 = 2.07.
Thank you for bringing your question here. I hope you find the answer useful. Don't hesitate to ask additional questions. Yes, as the level of tar rises, the concentration of carbon monoxide also increases.
Answer:
At least 315
Step-by-step explanation:
A journalist intends to find the average annual salary of CEOs within the S&P 1,500. Due to time constraints, a sample is used.
Standard deviation of the sample (s) = 449300
Sample size = n
Permissible margin of error = 50000
Z critical value = 1.96
Thus, 1.96 times the standard error equals 50000.
Standard error equals 25510.20
Standard deviation divided by the square root of n = 25510.20
By simplifying, we can derive:
Thus, the minimum sample size required is 315.
