Just a quick question: what is 1 + 1

answer: two

step-by-step explanation: i + i = ii

answer:

2

step-by-step explanation:

(let the variable k represent the equation 1 + 1.)

that means the following equation is also true:

k - 1 = (1 + 1) - 1

this can then be simplified:

k - 1 = 1

(assuming both (k - 1) and k itself are both greater than 0)

next, square both sides:

(k - 1)² = 1²

then subtract 1 from each side:

k² - 2k + 1 - 1 = 1 - 1

factor this equation:

k × (k - 2) = 0

this equation implies that the variable k equals either 0 or 2. however, as clarified before, k is a number greater than 0, meaning k = 2

k = 2 and k = 1 + 1, meaning that 1 + 1 is mathematically equivalent to 2.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
