A covalent bond is formed between non metal atoms, which combine together by sharing electrons. Covalent compounds have no free electrons and no ions so they don't conduct electricity
Explanation:
The 25th percentile New SAT score is 1450, and the 75th percentile SAT score is 1570. In other words, a 1450 places you below average, while a 1570 will move you up to above average. There's no absolute SAT requirement at Duke, but they really want to see at least a 1450 to have a chance at being considered.
Answer:
9/22 or 40.9%
Explanation:
Probability describes the likelihood of an event. To find simple probability, like in this question, use division.
To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.
This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.
If you want to find the percentage, simplify the fraction and convert it to a percentage.
Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.
