In a math class with 25 students, a test was given the same day that an assignment
was due. There were 15 students who passed the test and 16 students who completed
the assignment. There were 6 students who failed the test and also did not complete
the assignment. What is the probability that a student who completed the homework
passed the test?
We can confirm that the probability of a student who completed the assignment receiving a passing grade is above 90%.
How can we calculate this probability?We can arrive at this number with the information given to us. We are told that of the 16 students who successfully completed the assignment, 15 received passing grades. By dividing this number we can find the percentage of these students that passed, and this serves as the probability, which results in roughly 93%.
Therefore, we can confirm that the probability of a student who completed the assignment receiving a passing grade is above 90%.

They are various forms of sugars.
They are various forms of proteins.
Answer:
They are all carbohydrates.
Explanation:
Homo polysaccharides include starch, glycogen, and cellulose (same type of sugar-all made of glucose).
1- Amylose and Amyloprotein are the components of starch. Amylose is a branched chain with alpha 1–4 and alpha 1–6 at the branch point, whereas Amylopectin is a linear chain with alpha 1–4 and alpha 1–6 at the branch point.
2- Glycogen is created by forming a branched chain from glucose at alpha 1–6. It has a lot of branches.
3- Cellulose is a linear chain of glucose molecules with beta bonds.
Starch and glycogen serve as short-term energy stores in plants and animals, cellulose found in plant cell wall only.

Explanation:
Researchers have observed striped
hyenas and gray wolves hunting
together in certain areas
One hypothesis suggests that changing
hunting behavior aids both species in
obtaining better
