Answer:
Equivalent expression for n x a = a+ a+a+a....n times
Step-by-step explanation:
Given: Expression for n x a .
To find : Write an equivalent expression for n x a using only addition.
Solution : We have given that n x a .
Here, we can say Sum of a is n times.
We can rewrite it n x a = a+ a+a+a....n times.
Example : 3 x 2 = 2 +2+ 2.
6 = 6 ( true)
Therefore , equivalent expression for n x a = a+ a+a+a....n times.
Answer:
sensitivity analysis
Step-by-step explanation:
The ability to examine the variability of a solution due to changes in the formulation of a problem is an important part of the analysis of the results. This type of analysis is called Sensitivity analysis.
It helps us figure out the robustness of a system or model in the presence of an uncertainty
It also increases the relationship between the inputs and outputs from the system or model
Answer:
Option (b)
Step-by-step explanation:
It is given that,
Total no of friends are 6
The share of each friend is 4/5
Pizza eaten by each friend is equal to the total pizza eaten divided by total no of friends. It can be given by :
It means that Teagan is correct in using a division expression because the question is about splitting a value into equal parts. Hence, the correct option is (b).
