The answer to your question is 4 minutes
It is A, 1/5 hopefully i am the BRAINLIEST!!!!!
Applying log rules leaves us with the following equation:
x^2 + 8 = 6x
Change to standard form and solve using factoring.
x^2 - 6x + 8 = 0
(x - 4)(x - 2) = 0
x = 4
x = 2
Hope this helps!
Answer:
Step-by-step explanation:
- <u>Solve equation to find answer(s)</u>
<u></u>
Combine: 6z - 3z = 3z
Add: -2 + 3 = 1
Add 7 to both sides:
Simplify:
Divide both sides by 3:
Simplify:
- M -
The sample % of these two populations would be 100/size (of student body at each school) x 100 so this would compare the two student bodies preferences for the particular type of candy bar. However, the actual % of the whole student body at each school would be a factor also. If the high school only had 200 students then this would be 50% representative but if the middle school had say 500 students this would only be 20% representative so this would have to be taken into account too. It might be more representative to have the same % of the student bodies respectively for the sample.
