Answer:
The social studies teacher should draw a random sample from all the students in each grade.
Step-by-step explanation:
The teachers will not be doing the activity, so their opinion is irrelevant. All boys in each grade targets a some audience and leaves the girl's voices unheard. All the students in the social studies club only represent a small portion of students who take the class. A poll of all the students in each grade will give the teacher the results they desire.
(Also, the formatting of this question is absolutely <em>horrible.</em> I had to reread it several times to understand the question. If you want people to answer you, make it legible.)
24:16 which is simplified by dividing both sides by 8 so it becomes:
3:2
Hope this helps :)
X = -1 is the answer to -2x2+x+8=0
Answer:
The correct answer is t < 60.
Step-by-step explanation:
Lauren wants to keep her cell phone bill below $60 per month.
Lauren's current cellphone plan charges her a fixed price of $30 and per text price for one text is $0.50.
Let Lauren sends t texts in a complete month.
Total money spent on texts in a month is given by $ (0.50 × t)
Therefore Lauren's total spent in a month is given by $ (30 + (0.50 × t)).
But this amount should be under $60 as per as the given problem.
∴ 30 + (0.50 × t) < 60
⇒ (0.50 × t) < 30
⇒ t < 
⇒ t < 60.
So in order to keep her phone monthly bill under $60, Lauren should keep her number of texts below 60.
Answer:
