The quadratic form is ax^2 + bx + c
The given equation is 6x^2 -30 = 0
a = 6 because it is with x^2.
There is no x term in the equation so b is 0
c is the numerical term with no variable so c = -30
a = 6
b = 0
c =-30
Answer:
x^2 - 2x + 1
Step-by-step explanation:
(x-1)^2 = (x-1)(x-1)
= x^2 - x - x + 1
= x^2 - 2x + 1
Answer:
hypergeometric
Step-by-step explanation:
For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.
There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.
56 * .75 = 42
42+ 56 = 98
Answer is 98
