To find the average, add up all the numbers, then divide that answer by the quantity of numbers.
STEP 1:
add all numbers
=30 + 20 + 0 + 0 + 0 + 0 + 120
=170 total
STEP 2:
divide total from step 1 by 7 (total quantity of numbers given, including zeros)
=170 ÷ 7
=24.2857
=24.3 rounded to nearest tenth
***You could also calculate the average by adding only non-zero results (20,30,120) and then dividing by 3 (the quantity of only non-zero numbers).
ANSWER: The average number of minutes studied per day is 24.3.
Hope this helps! :)
Answer:
-2<x<9
Step-by-step explanation:
−21<−3x+6<12-21<-3x+6<12

−27<−3x<6-27<-3x<6
Divide each term in the inequality by −3-3.
−27−3>−3x−3>6−3-27-3>-3x-3>6-3
Divide −27-27 by −3-3.
9>−3x−3>6−39>-3x-3>6-3
Cancel the common factor of −3-3.
Tap for more steps...
9>x>6−39>x>6-3
Divide 66 by −3-3.
9>x>−29>x>-2
Rewrite the interval so that the left value is less than the right value. This is the correct way to write an interval solution.
−2<x<9-2<x<9
The result can be shown in multiple forms.
Inequality Form:
−2<x<9-2<x<9
Interval Notation:
(−2,9)
