20x-28+12=16x+24 (i distributed the 4 to get this)

20x-16=16x+24 (added -28 & 12)

4x=40 (Subtracted 16x from both sides and added 16 to both sides)

(divide by 4 on both sides)

x=10

For each random variable defined here, describe the set of possible values for the variable, and state whether the variable is d

Alona [7]

Answer:

X is a discrete random variable.

X can take values from 0 to 12:

$X\in[0,1,2,3,4,5,6,7,8,9,10,11,12]$

Step-by-step explanation:

(a) X = the number of unbroken eggs in a randomly chosen standard egg carton

X is a discrete random variable.

The minimum amount of eggs broken is 0 and the maximum amount of eggs broken is 12 (assuming a dozen egg carton).

Then, X can take values from 0 to 12:

$X\in[0,1,2,3,4,5,6,7,8,9,10,11,12]$

About the probability ditribution nothing can be said, because there is no information about it (it can be a binomial, uniform or non-standard distribution).

Find f(6) if f(x)=x^2 divided by 3x+x

Alinara [238K]

So, if I'm understanding you correctly, f(x)=x^2 divided by 3x+x, or
f(x) = (x^2)/(3x+x)
f(6) --> plug the 6 in to all values of x --> f(6) = (6^2)/(3×6 + 6) = 36/(18+6)
= 36/24 --> both are divisible by 12, so 36/12=3 and 24/12=2, now we have the reduced (simplified) answer:
f(6) = 3/2, or 1 1/2, or 1.5

HELP!!!!!!!!!!!!!!!!!!!!!!!!!! Can U Answer All These.

QUESTION 1

In figure A, the area of the bigger square is $625\:units^2$ . This means that the length of this square is the hypotenuse of the right angle triangle formed, which is $25\:units$ .

The area of the two smaller squares are $576\:units^2$ and $49\:units^2$ .

The length of these two squares form the two shorter legs of the right angle triangle, which are $24$ and $7$ units respectively.

Therefore we can write the equation, $576+49=625$ .

This implies that, $24^2+7^2=25^2$

We can see that the sum of the squares of the two shorter legs equals the square of the longer side which is the hypotenuse and this what the Pythagoras theorem says.

But in fig. B,

$5^2+4^2\ne 6^2$
