Answer:

Option OD - 9

Step-by-step explanation:

Given : On the cardiac ward of a local hospital, there are 7 nursing assistants. The seven assistants have 7, 8, 5, 9, 10, 10, and 14 patients, respectively, that they assist.

To find : What is the average number of patients per nursing assistant?

Solution :

The average number of patients per nursing assistant is given by the division of sum of number of patients by total number of nursing.

So, $\text{Average} =\frac{\text{Sum of patients}}{\text{Number of assistants}}$

$\text{Average} =\frac{7+8+5+9+10+10+14}{7}$

$\text{Average} =\frac{63}{7}$

$\text{Average} =9$

Therefore, The average number of patients per nursing assistant is 9.

So, Option OD is correct.

Can you ever use a calculator to determine if a number is rational or irrational

Tcecarenko [31]

By definition and according to Google:

"Irrational numbers cannot be represented as terminating or repeating decimals."

So the answer to your question would have to be 'no' as calculators were designed to give us approximate answers when dealing with irrational numbers.

It would be hard to guess whether a large number produced by a calculator is irrational or not given that fact that many rational numbers can be incredibly long.
