The answer is:
A Ramdom variable is a function that assigns a numerical value to every possible outcome in a sample space.
It is a number that represents a result of an event or a random experiment. This variable does not depend on other factors and its values are random, without a specific order. For example: when you roll a dice, the number that you get is a random variable, because in 6 attempts you may get 1,6,4,2,2,5 and then, in another 6 attempts, you may get 3,3, 6,2,1,6.
1. Write in y=mx+b Form 8x+2y=18. 8x+2y=18 8 x + 2 y = 18. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.

It is not a very tough question as it has all the information's required to find the necessary answer. It is already given that 82 1/2% of a certain number is 330. It is required to find the unknown number. So we have to create an equation with a single unknown number.
Let us assume the number to be = x
then we can easily write the equation as given below.
82 1/2% x = 330
(165/4)%x = 330
(165/400)x = 330
x = (330 * 400)/165
= 2 * 400
= 800
So the unknown number is 800.
