An open box is to be made from a flat piece of material 14 inches long and 6 inches wide by cutting equal squares of length xfro

Ludmilka [50]

Answer:

$f(x)=x(14-2x)(6-2x)$

Step-by-step explanation:

We are given that

Length of flat piece of material=14 in

Width of flat piece of material=6 in

We have to find the volume of box as a function of x.

An open box is made from flat piece of material by cutting equal squares of length x from the corner and folding up the sides.

Therefore, Height of box=x in

Length of box=14-2x in

Width of box=6-2x in

We know that volume of box= $length\times breadth\times height$

Using the formula

Volume of box=f(x)= $x(14-2x)(6-2x)$

Students at an agricultural station conducted a study to compare geneticallymodified (GM) corn with regular corn. Each of 33 plo

OlgaM077 [116]

Answer:

Step-by-step explanation:

The given data is represented in the attachment.

a) Explain why yields from one type of corn are not independent of the yields from the other type of corn.

Yields from one type of corn are not independent of the yields from the other type of corn because, as the corns are planted in two similar plots, they could compete during watering process, even the amount of nutrients shared and the type of air. This means one corn may get more nutrients than the other. Therefore, they are not independent (they are dependent).

b) Based on the summary statistics, GM is expected to more likely obtain yield greater than 123, because 123 is greater than mean for regular corn but less than mean for GM corn.

Thus,

P(yield>123|GM)>0.5; and P(yield>123|Regular)<0.5
