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

Carl is raising money for his football team. He is selling chocolate bars for $1.50 each and cookies for $2. He sold all 20 of h
stich3 [128]

Answer:

Carl has to sell at least 8 cookies.

c\geq 7.5

Step-by-step explanation:

Carl gets \$1.50 by selling 1 chocolate bar.

Earning from chocolate bars:

Total\ chocolate\ bar=20\\\\Earning\ from\ one\ chocolate\ bar=\$1.50\\\\Total\ earning\ from\ chocolate\ bar=Total\ chocolate\ bar\times cost\ of\ 1\ chocolate\ bar=20\times 1.5=\$30

Earning From cookies:

Let\ total\ number\ of\ cookies=c\\\\Cost\ of\ 1\ cookie=\$2\\\\Earning\ from\ cookies=2\times c=2c

Total\ earning=Earning\ from\ cookies+Earning\ from\ cookies+Earning\ from\ chocolate\ bars\\\\Total\ earning=30+2c

Carl wants to raise at least \$55

Total\ earning\geq 55\\\\2c+30\geq 55\\\\2c\geq 55-30\\\\2c\geq 15\\\\c\geq7.5

If $3,000,000 is invested at 6% interest compounded continuously, how much
g100num [7]

Answer:

  $24,498,509.74

Step-by-step explanation:

The formula for the value as a function of time is ...

  V(t) = P·e^(rt)

Filling in the numbers and doing the arithmetic, we have ...

  V(35) = 3,000,000·e^(0.06·35) ≈ 24,498,509.74

Compounded continuously for 35 years, the investment will be worth $24,498,509.74.
