High school gives too much homework. Studies have shown that teenagers get less sleep because they are worried about homework. On the weekdays teenagers need about eight or more hours of sleep, but because of homework they cannot. Most of the time the homework we get we won't be using; unless we go into that business. There are times homework is a waste since most people don't do it. They use a lame excuse. Homework that we get we don't remember for a test. So why get it? How come we get too much homework? We don't sleep, don't do it, forget it at home, or don't need it when we are older. There are classes let's take math for instance, we get too much a week. There might be questions we have that our parents don't know. Instead of going outside we have to do homework. High school can be tough on us high schoolers. There's a lot expected of us. Especially homework. It will give us stress and tired through the day and night. Some high schoolers even drink caffeine to keep them up to do homework. That isn't healthy for us.
Hope this helps somewhat ^^
Answer:
5/12
Step-by-step explanation:
15 students went to hear the doctor speak and 21 students went to other sessions
How many students are there? 15 + 21 = 36 students
Therefore, the probability to randomly select a student that went to hear the doctor is , then simplifying it by 3 is .
If we want to express it in percentage it would be 41.6%
Answer: -1 and 1
Step-by-step explanation:
i gotchu, no worries!
first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)
then, evaluate it.
x^2 - 9 = -2^3
next, move the constant to the right.
x^2 - 9 = -8
next, calculate it.
x^2 = -8 + 9
simplify it.
x^2 = 1
finally separate the solutions.
x = 1
x = -1
