Considering the margin of error of a confidence interval, it is found that the correct option is:
It would be half as wide.
<h3>What is the margin of error of a confidence interval?</h3>
It is modeled by:
In which:
- s is the standard deviation.
From this, we get that the margin of error is inversely proportional to the square root of the sample size. Then, multiplying the sample size by 4, when it changes from 50 to 200, cuts the margin of error in half, making the interval half as wide.

10.56 as a fraction is 264 / 25
564% as a fraction is 141/250
The expression that represents this inequality must relate both temperatures, then it would look like this: -40°F < x < 140°F.
<h3>How to write this situation with an inequality?</h3>
To express this situation in an inequality we must include the temperature values. Additionally, we must include the greater than (>) or less than (<) symbols to relate the values.
According to the above, the expression would look like this:
Note: This question is incomplete because some information is missing. Here is the information:
A truck driver is driving from Nome, Alaska to Death Valley, California. Because he is traveling between locations with extreme temperatures, he needs to check the weather continuously to make sure the gas in his truck remains in liquid form. The gas he uses freezes at −40° F and evaporates at 140° F.
Write an inequality to represent the temperatures at which the gas in the truck will remain in liquid form.

Just multiply the sum of the light
We can take the equation,
0.19x + 21.58 = 25
0.19x = 25 - 21.58
0.19x = 3.42
x = 3.42/0.19
x = 18
The answer is 18 minutes!
