Answer:
27% and 37%
Step-by-step explanation:
The percentage of students against year-round schooling = 68%
The percentage of students in favor of year-round schooling = 32%
Margin of error = ± 5%
We need to create an equation with absolute values to determine the lower and upper limits of students supporting year-round schooling.
<pGiven that, the supporting percentage is 32% and the margin of error is 5%, this results in a variation of 5%, either adding or subtracting.<pThis can be expressed as:
| x - 32 | = 5
Where x signifies the lowest and highest percentages.
<pExpanding gives us:
x - 32 = -5 or x - 32 = 5
x = -5 + 32 or x = 5 + 32
x = 27% x= 37%
<pThis indicates that the smallest percentage of students who might support year-round schooling is 27%, while the maximum is 37%.
Option A. A set of solutions.
3.6 * 10^(-3) represents the scientific notation
The formula for distance is d=rt. If Eddie covers 72 meters in 12 seconds, his rate is 6 meters per second.
d=rt
72=r·12
r=6
d=6t
The answer is c.
