600,000,000 + 20,000,000 + 5,000,000 + 80,000 + 7,000 + 400 + 30 + 5
Median mean to find the center of the data
Use the given information to write an equation, then solve it.
$1600 = (1 + 1 + 1/2)×(monthly rent) . . . . relationship given in the problem statement
$1600/2.5 = monthly rent = $640 . . . . divide by the coefficient of monthly rent
60 miles because 2160 divided by 36 = 60
The solution to the quadratic equation 3x² + 8x - 10 by using the quadratic formula is x = 0.927 or -3.594
<h3>Solving quadratic equations.</h3>
Quadratic equations are algebraic expressions that are represented in the power of the second degree. They usually take the form ax² + bx + c
From the given information, we are to solve the quadratic equation:
Using the quadratic formula:
![\mathbf{=\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%5Cdfrac%7B-b%20%5Cpm%20%5Csqrt%7Bb%5E2%20-%204ac%7D%7D%7B2a%7D%7D)
where:
![\mathbf{= \dfrac{-(8)) \pm \sqrt{(8)^2 - 4(3 \times (-10))}}{2(3)}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%20%5Cdfrac%7B-%288%29%29%20%5Cpm%20%5Csqrt%7B%288%29%5E2%20-%204%283%20%5Ctimes%20%28-10%29%29%7D%7D%7B2%283%29%7D%7D)
![\mathbf{= \dfrac{-(8)) \pm \sqrt{64 -4 (-30)}}{6}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%20%5Cdfrac%7B-%288%29%29%20%5Cpm%20%5Csqrt%7B64%20-4%20%28-30%29%7D%7D%7B6%7D%7D)
![\mathbf{= \dfrac{-(8)) \pm \sqrt{64+120}}{6}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%20%5Cdfrac%7B-%288%29%29%20%5Cpm%20%5Csqrt%7B64%2B120%7D%7D%7B6%7D%7D)
x = 0.927 or -3.594
