the table below:
Grade In favor Opposed Undecided Total
Grade 9 6 4 8 18
Grade 10 10 11 9 30
Grade 11 12 15 11 38
Grade 12 15 6 14 35
If the principal randomly selects a student in grade 10 from this survey,
the probability that the student is opposed to extending the school day
P ( student in grade 10 is opposed)= Number of student in opposed(grade10) / total number of students in grade 10
Number of student opposed who is in grade10 = 11
total number of students in grade 10 = 30
P( student in grade 10 is opposed)= ![\frac{11}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B30%7D)
= 0.37
the probability that the student is opposed to extending the school day= 0.37
Answer: =(x - 1) x (x^2 + x + 1)
Answer:
![f(300)=906](https://tex.z-dn.net/?f=f%28300%29%3D906)
Step-by-step explanation:
![f(x)=3x+6\\\\f(300)=3(300)+6\\\\f(300)=900+6\\\\\boxed{f(300)=906}](https://tex.z-dn.net/?f=f%28x%29%3D3x%2B6%5C%5C%5C%5Cf%28300%29%3D3%28300%29%2B6%5C%5C%5C%5Cf%28300%29%3D900%2B6%5C%5C%5C%5C%5Cboxed%7Bf%28300%29%3D906%7D)
Hope this helps.
Answer: x = 27
Step-by-step explanation:
2x+3x+45=180º because all of the angles of a triangle add up to 180
5x=180-45
5x=135
x=135/5
x=27
