How many 3-letter sequences can be formed if the second letter must be a vowel (A, E, I, O, or U), and the third letter must be

erica [24]

Answer:

120 ways

Step-by-step explanation:

Given that, 3-letter sequences should be formed, where the second letter must be a vowel (A, E, I, O, U) and the third letter must differ from the first letter.

There are 26 alphabets in English,

so, firstly let us fix the second letter to be one of the vowels

now we are left with 25 alphabets and now let us fix the third letter to be an alphabet from the remaining 25 alphabets.

now, we are left with 24 alphabets and the first letter can be any of these 24 alphabets.

so, there are 24 ways to fill the sequence.

The same thing can be done with the other 4 vowels.

so, total number of ways = 5 × 24 = 120 ways.

Please help! Give explanation

Vera_Pavlovna [14]

A. These angles are not adjacent because they do not share a common line, ray, or segment. They only have point V in common. Note how V is the only letter to show up in the sequences NVP and UVF.

B. These segments are adjacent. We can tell by visually noticing that NVT and TVU share the ray VT. Without the drawing, we can tell they are adjacent because NVT and TVU both have "VT" in them (the order of V and T doesn't matter). See the diagram below.

C. These angles are not adjacent for similar reasoning as choice A above.

D. Same story as choice C and choice A. These angles are not adjacent.

E. Since B is true, this rules out choice E.

==============================

<h3>Final Answer: Choice B</h3><h3>NVT and TVU are adjacent angles.</h3>
