Step-by-step explanation:
T
You want to find the monthly average over the past 6 months.
July: $78.56
August: $30.21
September: $81.20
October: $79.08
November: $66.18
December: $100.75
Add all of these up
(July) $78.56
(August) $30.21
(September) $81.20
(October) $79.08
(November) $66.18
(December) + $100.75
----------------------------------------------
(Total cost) $435.88
There are 6 months you are calculating for, therefore divide the total (combined) cost of 6 months with the total number of months (in this case, 6)
$435.88 (total cost of 6 months) ÷ 6 (months)
The average cost per month of over the past 6 months is $72.66.
Answer:
![x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-%28-2%29%5C%C2%B1%5Csqrt%7B%28-2%29%5E2-4%283%29%280%29%7D%20%7D%7B2%283%29%7D)
Step-by-step explanation:
Quadratic formula:
when the equation is ![0=ax^2+bx+c](https://tex.z-dn.net/?f=0%3Dax%5E2%2Bbx%2Bc)
The given equation is
. Let's first arrange this so its format looks like
:
![1=-2x+3x^2+1](https://tex.z-dn.net/?f=1%3D-2x%2B3x%5E2%2B1)
![1=3x^2-2x+1](https://tex.z-dn.net/?f=1%3D3x%5E2-2x%2B1)
Subtract 1 from both sides of the equation
![1-1=3x^2-2x+1-1\\0=3x^2-2x+0](https://tex.z-dn.net/?f=1-1%3D3x%5E2-2x%2B1-1%5C%5C0%3D3x%5E2-2x%2B0)
Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:
![x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5C%C2%B1%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D%5C%5Cx%3D%5Cfrac%7B-%28-2%29%5C%C2%B1%5Csqrt%7B%28-2%29%5E2-4%283%29%280%29%7D%20%7D%7B2%283%29%7D)
I hope this helps!
Answer:
The individual has 36.09 pounds of body fat.
Step-by-step explanation:
Given that an individual has a body fat percentage of 19.3% and weighs 187 pounds, to determine how many pounds of her weight is made up of fat the following calculation must be performed:
(187 x 19.3) / 100 = X
3.609.1 / 100 = X
36.091 = X
Therefore, the individual has 36.09 pounds of body fat.
