So all u have to do is say all the x values that have a point (the domain) and all the y values that have a point (the range). If it is continuous, like a line, then u say all the points between two points. For example the range of the bottom right is [-1,5]. If it goes to infinity or negative infinity, you say something like (-infinity,infinity). With the sideways 8 of course. Btw, (-infinity, infinity) is the domain of the bottom right ;D
Answer:
the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles. Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
Step-by-step explanation:
i got it from mathematics.org
21/60 is the experimental. The number of times you got orange over the total spins. The answer is 7/20 when reduced which makes Purple the one that matches.
So a) 7/20 and b) Purple?
X/8+12=16
Subtract 12 to both side
x/8+12-12=16-12
x/8=4
Multiply each side by 8
(x/8)8=4(8)
x=32
Check:
Substitute x with 32
32/8+12=16
4+12=16
16=16. As a result, x equal 32. Hope it help!
