The specifications for a new cardboard container require that the width for the container be 4 inches less than the length and t
Levart [38]

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.

Dr.sox paid $1580 for a new computer system. She also paid 6.5% sales tax. How much was total cost?
Andru [333]

Answer:

$1,682.70

Step-by-step explanation:

  1. 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
  2. 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>
  3. 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.

Find the standard deviation for the group of data items 4, 4, 4, 4, 6, 8 The standard deviation is (Simplify your answer. Round
marysya [2.9K]

Answer: 1.53

Step-by-step explanation:

The given data : 4, 4, 4, 4, 6, 8

Number of data values : n= 6

The mean value of the given data will be  :-

\overline{x}=\dfrac{\sum_{i=1}^{6}x_i}{n}\\\\\Rightarrow\ \overline{x}=\dfrac{30}{6}=5

The formula to find standard deviation:_

\sqrt{\dfrac{\sum(x-\overline{x})^2}{n}]

Now,

\sum_{i=1}^{6}(x_i-\overline{x})^2=(-1)^2+(-1)^2+(-1)^2+(-1)^2+(1)^2+(3)^2\\\\=1+1+1+1+1+9=14

The standard deviation will be :-

\sigma=\sqrt{\dfrac{14}{6}}\approx1.53
