Answer:
10 ways
Step-by-step explanation:
Here, we want to calculate the number of ways in which the selection can be made
We have this as follows;
Since we have style starting line up already, it means a choice of 5 has been made from the 13 already. What is left is to make a selection of 3 from 5
To do this, we simply apply the combination formula
that would be;
5 C 3 = 10 ways
132=2*66=2*2*33=2*2*3*11=2²*3*11
For this case the first thing you should know is that if the coefficient of determination (R) is equal to 1, the graph is totally perfect.
Therefore, the closer the value of R is to one, the mathematical model will be the most appropriate.
We have then:
The coefficient of determination for the linear model was 0.95.
Therefore, the mathematical model must be linear.
Answer:
A model that should be used to represent the data set is:
A linear
The answer is actually 1.571
