Answer:
n =7 or n = -17/3
Step-by-step explanation:
10 - |3n - 2| = -9 (subtract 10 from both sides)
- |3n - 2| = -9 - 10
- |3n - 2| = -19 (multiply both sides by -1)
|3n - 2| = 19
(3n - 2) = 19 or (3n - 2) = -19
For (3n - 2) = 19,
3n - 2 = 19
3n = 21
n =7 (answer)
For (3n - 2) = -19,
3n - 2 = -19
3n = -17
n = -17/3 (answer)
It would be; -7/9 + 2/3
= -7+6 / 9
= -1/9
In short, Your Final Answer is -1/9
Hope this helps!
Answer:
187,500
Step-by-step explanation:
each seat is 12.50$
there are 15,000 seats
so you multiply 12.50$ by 15,000
12.50+15000= 187,500
Answer:
A. Increase the level of confidence
Step-by-step explanation:
The margin of error is given by:
The margin of error is:
In which T is related to the level of confidence(the higher the level of confidence, the higher T is), s is the standard deviation of the sample and n is the size of the sample.
Increase the width:
That is, increasing the margin of error, as the width is twice the margin of error, the possible options are:
Increase T -> increase confidence level.
Increase s -> Increase the standard deviation of the sample.
Decrease n -> Decrease the sample size.
Thus, the correct answer is given by option A.
