Answer:
c) Length = 12, width = 8 and height = 23.
Step-by-step explanation:
Let the length be x, then the width = x - 4 and the height = 2x - 1.
a) The polynomial is x(x - 4)(2x - 1)
b) x(x - 4)(2x - 1) = 2208
c) x(x - 4)(2x - 1) - 2280 = 0
2x^3 - 9x^2 + 4x - 2280 = 0
I'll use graphical software to find a solution for this. Its easily obtained online.
There is one real root and its x = 12.
So the dimensions of the box are L = 12, W = 8 and H = 23 inches.
Answer:
$1,682.70
Step-by-step explanation:
- Convert the percent into a decimal by multiplying by 0.01: the percent in this problem is 6.5%, so when you multiply by 0.01, you get 0.065
- Multiply the price by your new decimal: in this case, that would mean to multiply 1580 by 0.065, which gives you 102.7. <u>Keep in mind that this is just the tax, not your final answer.</u>
- Add the tax you just calculated to the original price: add 102.7 to 1580 to get 1,682.7. That is your final answer.

The formula to find standard deviation:_
![\sqrt{\dfrac{\sum(x-\overline{x})^2}{n}]](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cdfrac%7B%5Csum%28x-%5Coverline%7Bx%7D%29%5E2%7D%7Bn%7D%5D)
Now,
The standard deviation will be :-
Answer:
$131.20
Step-by-step explanation:
$160 is the full price, so it is 100% of the full price.
With a discount of 18%, you pay 100% - 18% = 82% of the full price.
82% of $160 =
= 0.82 * $160
= $131.20
Answer: $131.20
