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

F it costs $90 to feed a family of 3 for one week. (3 points)
Nataly [62]
Given:
$90 good for 3 pax for 1 week.

a) $90 / 3 = $30 cost to feed each person in a week
b) $30 cost to feed each person * 5 persons = $150
c) $30 cost to feed each person * 6 persons in a family = $180 

The formula derived from the above facts is:

Total cost = cost per person * no. of person * no. of weeks.

Assuming = 6 persons for 2 weeks
Total cost = 30 x 6 x 2
Total cost = 180 x 2
Total cost = 360 cost to feed a family of 6 in 2 weeks.

A farmer has 220 bushels of apples to sell at roadside stand. She sells an average of 14 3/5 each day. Represent the total chang
Lyrx [107]

Answer:

Step-by-step explanation:

He has sold (16+1/4) bushels/day x 5 days = (16 x 5) + (1/4 x 5) = 80 + 5/4 = 81 + 1/4 = 81.25

The change in the number of bushels is 140 - 81.25 = 58.75 or 58 and 3/4 bushels

In other words, he has 58.75 (or 18 and 3/4) bushels remaining and has sold 81.25 (or 81 and 1/4) bushels

Andreyy89

The answer is 2 .

simplify log(down)10 (1/100) : -2

apply log rule : -log(down)10 (100)

rewrite 100 in power-base form : -log(down)10 (10^2)

apply log rule again : -2log(down)10 (10)

apply one more time : -2*1

Multiply : -2

refine from -(-2) = 2

I hope this helps

Guided Practice
spin [16.1K]

Answer:

A. {–8, –2, 18}

Step-by-step explanation:

y = 5x − 2

x = −1.2 ----> y = 5(−1.2) − 2 = −6 − 2 = −8

x = 0 -----> y = 5(0) − 2 = 0 − 2 = −2

x = 4 -----> y = 5(4) − 2 = 20 − 2 = 18
