3 0

Answer:

The student scores 20 pts

Step-by-step explanation:

A student answers 10 Q's correct, this earns the student 30 points (3 x 10)

The other 5 Q's are presumably wrong since they did answer the question

If every question wrong loses 2 pts then the student lost 10 points from wrong answers (2x5) =10

Take the total amount of secured points and subtract the points for questions that the student got wrong

30 pts - 10 pts = 20 pts

The following problem refers to strings in A, B, ..., Z.
pshichka [43]

Answer:  676

Step-by-step explanation:

The total number of letters in English alphabet {From A to Z} = 26

We assume that the repetition of letters is allowed.

If we fix H at the first position , then the number of ways to make three-letter strings that begin with H is given by :-

1\times26\times26=676

Hence, the number of ways to make three-letter strings that begin with H is 676.

A circle diameter is 11 cm a square has a side length of 7 cm
olasank [31]

Answer:

By the Pythagorean theorem, the diagonal length (d) of the square is

 d² = 7² + 7²

 d = √98 ≈ 9.8995

Since the diameter of the circle (11 cm) is greater than the diagonal length of the square (9.9 cm), you know the square will fit into the circle without touching.
