Answer:
See explanation
Step-by-step explanation:
Ana started the work nicely by multiplying out factors to get:\
![(x+4)(x+2)(2x+1)(x-2)=0](https://tex.z-dn.net/?f=%28x%2B4%29%28x%2B2%29%282x%2B1%29%28x-2%29%3D0)
She multiplied
correctly using difference of two squares to get: ![x^2-4](https://tex.z-dn.net/?f=x%5E2-4)
Unfortunately: She made a mistake in multiplying
she mistakenly got
instead of
. <em>She left out the coefficient of 2.</em>
Therefore the second step should have been:
![(x^2-4)(2x^2+9x+4)](https://tex.z-dn.net/?f=%28x%5E2-4%29%282x%5E2%2B9x%2B4%29)
The next step will now be:
![2x^4+9x^3+4x^2-8x^4-36x-16=0](https://tex.z-dn.net/?f=2x%5E4%2B9x%5E3%2B4x%5E2-8x%5E4-36x-16%3D0)
This simplifies to
![2x^4+9x^3-x^4-36x-16=0](https://tex.z-dn.net/?f=2x%5E4%2B9x%5E3-x%5E4-36x-16%3D0)
Your answer is going to be 578 because you had to add 300+210+40+28 and it = to 578 your welcome
You would have paid in full with on interest so $859
Answer:
b) Median 32; Q1 =27
Step-by-step explanation:
- The description to the left directs us how to draw the box and whiskers. Using the markings. 20, 25, 30, 35, 40,45 check on the left side of the graph.
- <em>The box extends from 27 to 38 on the number line.</em> So, that means Q1=27 and Q3=38
- <em>The whiskers end at 20 and 42. </em>The minimum and the Maximum value of the Distribution, the "whisker".
- <em>A line in the box is at 32. </em>The horizontal line the slices the box, in other words the Median.
So here it is, our Box and Whiskers Plot.
