How many different strings of length 12 containing exactly five a's can be chosen over the following alphabets? (a) The alphabet

N76 [4]

Answer:

Part (A) The required ways are 792.

Part (B) The required ways are 101376.

Step-by-step explanation:

Consider the provided information.

Part (A) The alphabet {a, b}

The length of strings is 12 that containing exactly five a's.

The number of ways are: $\frac{12!}{5!7!}$

After filling "a" we have now 7 places.

For 7 places we have "a" and "b" alphabet but we already select a's so now the remaining place have to fill by "b" only.

Thus, the required ways are: $\frac{12!}{5!7!}\times 1=792$

Part (B) The alphabet {a, b, c}

We have selected five a's now we have now 7 places.

For 7 places we have "b" and "c".

Thus, there are 2 choices for each 7 place that is $2^7$

Therefore the total number of ways are: $792\times 2^7=101376$

Thus, the required ways are 101376.

Use only ‘rays’ and ‘angles’ to answer. thank you :)) zoom in to see more clearly.

Nadya [2.5K]

answer:

(a) ∠SQR, ∠2

(b) Q

Step-by-step explanation:

(a) There are many ways in which we can rename angles, but most of the time, they must share a common "center letter" for them to be the same angle. Sometimes, changing the order of first and third letters of the angles works as a way of renaming angles.

(b) The vertex of an angle will always be the letter located "second" of it. For example, if we have ∠ABC, then the vertex will be B.

(c) The sides of an angle are the two lines that form an angle. When you write a side, you will write two letters that identify the line.
