Answer:

x = 35

Step-by-step explanation:

x = 35, because first you have to add all your like factors. Then you'd get 2x + 110 = 180, afterwards you'd subtract 110 from both sides. Then divide 2 on both sides. Leaving you with x = 35.

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).
