Answer:
84.3211111111/ 84.32/ 84.3
Step-by-step explanation:
In order to find range, you have to add all the numbers up and then divide by the amount of numbers that you have. So, you'd do 90.89+ 87+ 79+ 89+ 84+ 80+ 85+ 85+ 79= 758.89. Then, since you have nine numbers, you'd divide 758.89 by nine, which equals 84.3211111111, and is rounded to 84.32, or 84.3.
It is increasing at (−∞, 0) and (1, 2)
Answer:
Robot will take
hour to complete each task.
The robot can complete
tasks in one hour.
Step-by-step explanation:
We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.
To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:

Now we will convert division problem into multiplication problem by flipping the 2nd fraction.


Therefore, robot will take
hour to complete each task.
To find tasks completed by robot in one hour we will use proportions.




Therefore, the robot can complete
tasks in one hour.
