Answer:
rounding and sig figs
Step-by-step explanation:
First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
First, let's try to isolate x to make the question easier to solve.
|2x-6|≤6
2x - 6 ≤ 6
2x - 6 ≥ -6
2x ≤ 12
x ≤ 6
2x ≥ 0
x ≥ 0
Knowing this, the graph should be equal or less than 6 and equal or greater than 0, making Option D the correct answer.
The mean is 2.56 or 3 if you round up. you add all the numbers and then divide the answer by however many numbers there were.
