A certain stock exchange designates each stock with a one-, two-, or three-letter code, where each letter is selected from the 2

Sophie [7]

Answer: Option 'e' is correct.

Step-by-step explanation:

Since we have given that

Number of letters of the alphabet = 26

Number of letters in code :

One letter code, or two letter code, or three - letter code.

Since repetition of letters are allowed, then

if it is one letter code, the number of arrangement would be 26.

If it is two letter code, the number of arrangements would be

$26\times 26\\\\=26^2\\\\=676$

If it is three letter code, the number of arrangements would be

$26\times 26\times 26\\\\=26^3\\\\=17576$

So, Number of different stocks to uniquely designate with these codes would be

$26+676+17576\\\\=18278$

Hence, Option 'e' is correct.

Which ordered pair will solve the equation 2 × 4 + x = y?

Bezzdna [24]

This answer uses NMF, which you can find out about on my profile:

Preliminary work:
Following the BIDMAS order of operations, we can calculate part of it already, and that's the 2•4, which equals 8.
Therefore, the equation now reads:
8+x = y

x = 5:
8+5 = 13
13 ≠ 16
13 ≠ y

x = 4:
8+4 = 12
12 = 12
12 = y

Therefore, the pair is (4, 12)
