So if you have 2/3 then it flips so the top number or numberator is in the house (aka dividend)
Because -7i and 7i are the solutions to the quadratic equation, you can first write it in factored form (x-7i)(x+7i). The you multiply this out and get x^{2} +49.
Put both values into a ratio

Answer: 0.85 kilograms
Step-by-step explanation:
The correct answer to this question is 1/5. To solve this, since 90 numbers exist in the range from 10 to 99, and 18 of them are divisible by 5, place these two numbers into the formula for probability.
Probability = target outcomes / total outcomes = 18 / 90
= 1/5
