The answer you are looking for is y=5/2x-2.
Answer:
x=291/76
Step-by-step explanation:
Convert:
1/2x(6x+ 1/2)=-0.8x+16-1.2
Remove parenthesis and move terms:
3x+1/4=-0.8x+14.8
Collect the like terms and convert:
3x+0.8x=14.8-1/4
Subtract the fractions:
3.8x=74/5-1/4
Divide both sides by 3.8:
3.8x=291/20
x=291/76
Answer:
A student finds a 95% confidence interval of (16.34,18.69) for the mean number of species counted. This is a valid interval because the mean number of species or any population mean does not necessarily have to be a whole number, as stated by the student.
This given confidence interval of (16.34,18.69) helps us to simply estimate the mean species counted.
Total distance is the distance per lap times the number of laps. (Note the units of "lap" cancel, leaving miles as the unit of the result.)
(3/8 mi/lap)×(3 1/2 lap) = (3/8)×(7/2) mi = 21/16 mi = 1 5/16 mi
The number with the same value as 32 tens is 320.
