Answer:

On this case n =6 and x =6 we got:

Step-by-step explanation:
The utility for the combination formula is in order to find the number of ways to order a set of elements
For this case we want to find the following expression:

And the general formula for combination is given by:

On this case n =6 and x =6 we got:

Answer:
y = 0.1491x + 0.7556
R² = 0.6943
r^2 at .69 ≅ .7 is somewhat strong
y = 0.1491(15) + 0.7556
GPA= 2.2365
Step-by-step explanation:
2)Since the score is 750, then the annual rate is 9.25% (see the table)
Then monthly rate:9.25/12=0.77%.
Then compute 0.77% from <span> $2,375.00 like this:
</span>

Answer: interest to pay: $18.30.
3)Compute monthly rate for first account:
9.75/12=0.81%
Compute 0.81% of $<span>1,675.00 like this:</span>

Second account:
compute monthly rate: 12.5/12=1.04%.
Then compute

Conclusion:
Monthly interest is $13.5+$17.4=$30.9
