The margin of error for the interval (200 miles, 250 miles) is 25 miles.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and number.
The confidence interval = mean (m) ± margin of error (e) = m ± e
Hence:
m + e = 250 (1)
m - e = 200 (2)
From the both equations:
m = 225, e = 25
The margin of error for the interval (200 miles, 250 miles) is 25 miles.

Answer:
26 is the number
Step-by-step explanation:
12/13 x = 24
Multiply by 13 on both sides
12x = 24 * 13
12x = 312
Simplify
x = 26
26
Hope this helps :)
-5¹/₂ + 11³/₄q = -¹/₄q + ¹/₂(8q - 1)
-5¹/₂ + 11³/₄q = -¹/₄q + ¹/₂(8q) - ¹/₂(1)
-5¹/₂ + 11³/₄q = -¹/₄q + 4q - ¹/₂
-5¹/₂ + 11³/₄q = 3³/₄q - ¹/₂
<u> - 3³/₄q - 3³/₄q </u>
-5¹/₂ + 8q = -¹/₂
<u>+ 5¹/₂ + 5¹/₂
</u> <u>8q</u> = <u>5
