1.
The vowels of the 26 letters of the English alphabet, excluding y, are 5:

a, e, i, o
and u.

2.
The prime numbers less than 10 are 4:    2, 3, 5 and 7.

3.

The raffle tickets have one of {a, e, i, o,u} as the first character, and 

one of {2, 3, 5, 7} as the second character.

4. Some examples of the raffle tickets: a2, a3, e5, i7 ...

In total there are 5*4=20 possible tickets, as any of the 5 vowels can be combined with any of the 4 primes.

that is, we have a2, a3, a5, a7, e2, e3, ....u7

5.

The only vowel contained in the word "event" is e.


"the digit is the number of letters in the word event":

the word "event" has 5 letters. 

--------------------------------------------------------------------------------------------------
Remark: it is not particularly clear whether it is "the number of letters" or "the number of different letters", in which case there would be 4.

For example, if Adam is asked how many letters are there in his name, we expect him to say "4", unless specifically asked "how many different letters are there"
--------------------------------------------------------------------------------------------------

The ticket which matches the description can only be e5

6.

P(e5)=(number of ways e5 may occur)/(total number of tickets)= 1/20=0.05


Answer: 1/20 = 0.05

If FC IS RS 4430 and the BEP in unitsis 89, then contribution margin is ?
Umnica [9.8K]

Answer: RS 49.8

Step-by-step explanation:

Given the following :

Fixed cost = RS 4430

Break even point = 89 units

Recall:

Break even point in units = Fixed cost ÷ contribution margin

Therefore,

Contribution margin equals;

(Fixed cost ÷ break even point in units)

= 4430 / 89

= 49.775280

= RS 49.8

The number 2400 is first increased by 30%.The value obtained is next decreased by 20%.Find the final number
kvasek [131]

<em>2400 is increased by 30%.</em>

so,

2400 + (30/100 * 2400)

2400 + (30 * 24)

2400 + 720

3120

<em>this number is decreased by 20%.</em>

so,

3120 - (20/100 * 3120)

3120 - (2 * 312)

3120 - 624

2496

therefore, the final number will be 2496.

Solve for x: 14-14x^1/3 =2
zmey [24]

Answer: 216/343 or 0.6297

Step-by-step explanation:

14-14x^{1/3} = 2\\14 -2 = 14x^{1/3}\\12 = 14x^{1/3}\\\frac{12}{14} =x^{1/3}\\\frac{6}{7} =x^{1/3}\\(\frac{6}{7})^3 =(x^{1/3})^3\\\frac{6^3}{7^3} =x\\\\\frac{216}{343} = 0.629737609 = x
