The 90% confidence interval is (70 - 4, 70 + 4). The margin of error is 4%.
An absolute value equation which could represent the length of a plane is : 12 feets ≥ x ≤ 302 feets
Smallest length of a plane = 12 feets
Longest length of a plane = 302 feets
This means that the minimum length of a plane cannot be below 12 feets and the maximum length of a plane cannot be above 302 feets
Using x as the length of a plane :
To represent as an absolute value ; we use inequality :
Minimum length ≥ x ≤ maximum length
12 feets ≥ x ≤ 302 feets .

Answer:
3
Step-by-step explanation:
- <em>Each of the seven happy clowns has a red nose.</em>
This means there are (15-7) 8 sad clowns.

7/8 × 20/1 = 140/8
140 ÷ 8 = 17.5
Once you convert to money, this is $17.50.
