For this, it's like finding a partial volume. Altogether, there will be 10 inches of sand, because 4+6 is 10. Because it is in inches, we have to convert it to feet. 10 inches in feet is 10/12 feet, or about .833. This is then used for the volume formula instead of the 1 foot height. So, the equation is 6 times 4 times 10/12. This comes out to be 20.
Hope this helps :)
180 = x + x+2 + x+1
180=3x+3
177= 3x
x = 59
Angle A = 59 +2 = 61 degrees
For uniform, the mean is:
<span>x¯ = (<span>590.0+590.9) 2</span></span>
The variance is:<span>
σ = sqrt [ (<span><span>n2−1) /</span>12 ]
</span></span><span>
Where n=10.
The answer would be 590.45
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!</span>
