Ronald is making hats and scarves for charity. He has enough yarn to make 5 hats and 8 scarves. Takes him 12 hrs to knit a hat,
1 answer:
Constraints are simply the subjects of an objective function.
The inequality that represents the constraint is:
Represent the number of hats with x, and the number of scarves with y.
From the question, we have:
- He spends 12 hours to knit a hat
- He spends 6 hours to knit a scarf
So, the equation of the total time spent is:
This time spent is not more than 20 hours.
So, the inequality is
Hence, the inequality that represents the constraint is:

Answer:
The degrees of freedom for this problem are 21
Step-by-step explanation:
Degrees of freedom:
When testing an hypothesis involving two samples, the number of degrees of freedom is given by:
In which is the size of the first sample and
is the sample of the second sample.
In this question:
Samples of 9 and 14, so
The degrees of freedom for this problem are
The degrees of freedom for this problem are 21
