Find the range of the following data. Scores:90.89,87,79,89,84,80,85,85,79
S_A_V [24]

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.

A robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time. How long does it take the robot to complete
Vsevolod [243]

Answer:

Robot will take \frac{3}{80} hour to complete each task.

The robot can complete 26\frac{2}{3} 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:

\text{Time taken by robot to complete each task}=\frac{3}{10}\div 8  

\text{Time taken by robot to complete each task}=\frac{3}{10}\div \frac{8}{1}

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

\text{Time taken by robot to complete each task}=\frac{3}{10}\times \frac{1}{8}

\text{Time taken by robot to complete each task}=\frac{3}{80}

Therefore, robot will take \frac{3}{80} hour to complete each task.

To find tasks completed by robot in one hour we will use proportions.

\frac{x}{1\text{ hour}}=\frac{8}{\frac{3}{10}}

\frac{x}{1}=\frac{80}{3}

x=\frac{80}{3}

x=26\frac{2}{3}

Therefore, the robot can complete 26\frac{2}{3} tasks in one hour.
