<span>There are 100 * 99 = 9900 different ways to choose two students out of 100 bandmembers. You and our brother are 2 of that ways: you being selected first and you being selected second. Therefore the probability that you two are selected is 2 / 9900 = 0,000202. You can also think as the probability of you being selected among 100 bandmembers, which is 1/100, times the probability of your brother being selected among 99 members, which is 1/99 => (1/100) * (1/99) = 1/ (100*99) = 1 / 9900; plus the same for your brother being selected first and you second => [1/9900] * 2 = 2/9900, which is the same calculated above.</span>
Answer:
3 Questions
Step-by-step explanation:
After MM students took a test, there was a total of 64% of correct answers.
The tests contained a total of 50 questions.
Number of questions gotten to score 64%= 64% X 50 = 32 questions
If the next student wants to score 70%, he has to score
70% of the total score = 70% X 50 = 35
Therefore the least number of question more the student has to get right
=35-32
= 3 questions
Combine like terms on the right side of the equal sign:
7 - 3x = - 3x + 7
You can rearrange the right side to be:
7 - 3x = 7 - 3x
Because are the same thing, your answer ends up being all real numbers or infinitely many solutions. This means whatever number you plug in for the x-variable, the two sides will always be equal to each other.
