Answer:

<h2>Option 2 is the right answer.</h2>

Step-by-step explanation:

We need to check if the two characteristics, <u>having blue eyes and being deaf are independent of each other or not</u>.

The above two characteristics will be independent if $[Probability of being deaf with blue eyes] = {Probability of being deaf } {Probability of having blue eyes}$

Now, the probability of having blue eyes is $\frac{31}{100}$ .

The probability that the Dalmatians will be deaf is $\frac{38}{100}$ .

The probability of being deaf with blue eyes is $\frac{31}{100} \times\frac{42}{100}$ .

Since, 38 is not equals to 42, the two characteristics are not independent.

From a 28-inch by 28-inch piece of metal, squares are cut out of the four corners so that the sides can then be folded up to mak

elixir [45]

Answer:t The volume of the box as a function of x is given by

$Volume=(28-2x)^2x$

Step-by-step explanation:

Since we have given that

Length of metal = 28 inch

Width of metal = 28 inch

Since squares are cut out of the four corners so that the sides can then be folded up to make a box.

Let the length of the sides of the squares that are cut out be 'x'.

So, Length of box would be

$28-2x$

Width of the box would be

$28-2x$

Height of the box would be x.

As we know the formula for "Volume of box":

$Volume=(28-2x)(28-2x)x\\\\Volume=(28-2x)^2x$

Hence, the volume of the box as a function of x is given by

$Volume=(28-2x)^2x$
