Answer:
The 95% confidence interval is 
This means that there is 95% chance that the true population mean is within this interval
Step-by-step explanation:
From the question we are told that
The sample size is n = 30
The sample mean is 
The population standard deviation is 
Given that the confidence level is 95% then the level of confidence is evaluate as


Next we obtain the critical value of
from the normal distribution table , the values is

Generally the margin of error is mathematically represented as

substituting values


The 95% confidence interval is mathematically represented as

substituting values


5x=440
×=the number of tickets sold
then you woukd just divide 440÷5=88
88 tickets were sold at the door
There is only one solution since they have different slopes.
Answer:
(6, 6)
Step-by-step explanation:
Each grid square is 2 units. 10 units up from point P is 5 grid squares up, or 3 grid squares above the x-axis. The x-coordinate remains the same (6), and the y-coordinate is the one labeling the 3rd line above the x-axis: 6.
The coordinates of point S are (6, 6).
