Answer:
x = -2
Step-by-step explanation:
Step 1: Define
f(x) = -x - 5
f(x) = -3
Step 2: Substitute and Evaluate
-3 = -x - 5
2 = -x
x = -2
Hello!
First, let's write the problem.
Subtract 3x from both sides.
The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.
Our final answer would be,
Thanks!

Using confidence interval concepts, it is found that the interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.
<h3>What is a confidence interval?</h3>
It is given by the <u>sample proportion plus/minus the margin of error</u>, and a x% confidence interval means that we are x% sure the population proportion is in the interval.
134 of 420 randomly chosen likely voters indicated that they planned to vote for the Democratic candidate, hence:
p = 134/420 = 0.319
The margin of error for the statistic is 0.045, hence:
0.319 - 0.045 = 0.274
0.319 + 0.045 = 0.364
The interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.
