A 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%
The 95% confidence interval for the proportion is expressed according to the formula;
p is the proportion = 268/400 = 0.67
z is the 95% z-score = 1.96
n is the sample space = 400
Substitute the given parameters into the formula to have:
Hence a 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x + 3
g(x) = -x + 2
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute in function values: (f + g)(x) = x + 3 - x + 2
- [Subtraction] Combine like terms (x): (f + g)(x) = 3 + 2
- Add: (f + g)(x) = 5
The answer is x > 4.5.
Explanation:
-24 > -6(x - 0.5)
-24 > -6x + 3
6x > 3 + 24
6x > 27
x > 27/6
x > 4.5
Hope this helps :)
