To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that
we can subtract twenty from each side
now we can subtract like terms
so we can get the final answer as
Using the z-distribution, as we have a proportion, the 95% confidence interval is (0.2316, 0.3112).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
We also consider that 130 out of the 479 season ticket holders spent $1000 or more at the previous two home football games, hence:
Hence the bounds of the interval are found as follows:
The 95% confidence interval is (0.2316, 0.3112).

Answer:
3w+7=9
Step-by-step explanation:
i need at least 20 characters so I just rote this
The line goes down 3 over to the right 4
-3/4
Choice B
The slope is -500. The bird descends......
3 boxes are filled every 4 minutes
.75 boxes are filled per minute
3 laps per minute is line B
The correct answer for the exercise shown above is the first option and the las option, which are:
<span>y = 3x + 20
3x - y = -20
</span>
The explanation is shown below:
1. You have the folllowing expression given in the problem above:
y-2=3(x+6)
2. If you solve it for y, you have:
y-2=3x+18
y=3x+18+2
y=3x+20
3. And if you move the variables to the left member, you have:
3x-y=-20
Therefore, as you can see, the correct answer are the options mentioned above.
