A recent Associated Press article out of Belgium indicated the European Union was considering a probe of computer makers after c

onsumers complained that they were being overcharged for ink cartridges. Companies such as Canon, Hewlett Packard and Epson are the printer market leaders and make most of their printer related profits from sales of replacement ink cartridges.
Suppose an independent test agency wishes to conduct a test to determine whether name-brand ink cartridges generate more color pages than competing generic ink cartridges. To test this theory 6 people are given both a name-brand color ink cartridge (Canon) and a generic color ink cartridge. The number of color pages each printed is counted. The agency used alpha =0.01.

Dimensions of a Box A large plywood box has a volume of . Its length is ft greater than its height, and its width is ft less tha
cupoosta [38]

Answer:

Few things are missing, they are volume of the box is 180 feet cube. Length is 9 feet greater than its height, and weight is 4 feet less than its height.

Step-by-step explanation:

Given, the volume of the box, V = 180 feet cube

Let the height of the box, h = x feet

Therefore, length is, l = ( 9+x ) feet

And width is, b = ( x-4) feet

so volume of the box is

V = l x b x h

$ 180= (x+9) \times (x-4) \times (x)$

$ x^3 +5x^2-36x -180 =0$

Factorizing we get

(x+5)(x-6)(x+6)=0

Therefore,

x = -5, -6, 6

Now since the height of the box cannot be negative, so taking the positive value of x, we get

Height of the box, h = x = 6 feet

Length , l = ( 9+x ) = 9+6 = 15 feet

Width , b = ( x-4) = 6-4 = 2 feet
