Answer:
B. No, because the sample was not random.
Step-by-step explanation:
The survey asks to find the favourite sport of the school's<em> students</em>. Not just the school's seventh graders. The seventh graders do not make up a random sample of the student body, and therefore the results of this survey are invalid.
Let's look at the answers:
A - No. We've already discussed why sampling just the seventh graders is wrong.
B - Yes. The entire seventh grade is not a random sample of the entire school and do not yield a valid response.
C - No. The school surveyed every seventh <em>grader</em>, not every seventh student. This is a play on words.
D - No. Every student in the seventh grade was sampled, not just girls.
Answer:
-x - 2
Step-by-step explanation:
Because you have negative (minus) sign before tha bracket so when you break it out, it would be opposite to the sign that is inside the bracket:
- (x + 5) + 3
= -x + (-5) + 3
= -x - 5 + 3
= -x -2
This is the simpliest form
