I'm pretty sure you just add all the numbers up so it would be 569.9 ft
The answer is -3 on apex:)
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.

The first one. An outlier doesn’t belong is the data. The first one has that 23 that doesn’t belong
Answer:
y-intercept is 10
slope of line is 7
Explanation:
The general form of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
Now, the given equation is:
y = 7x + 10
Comparing the given equation with the general form, we will find that:
m = 7 .............> This means that the slope of the line is 7
c = 10 ............> This means that the y-intercept is 10
Now, the y-intercept here means that the initial number of points at time = 0 (x=0) is 10 points.
The slope here means that the rate increases by 7 points each second
Hope this helps :)
