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

Answer:
15 feets
Step-by-step explanation:
The perimeter of a parallelogram is given as :
P = 2(l + w)
l and w are the bases :
Substituting the values into the equation :
P = 2(x + 75 + x + 45)
P = 2(2x + 120)
P = 300
Hence ;
300 = 4x + 240
300 - 240 = 4x
60 = 4x
Divide both sides by 4 to isolate x
60 /4 = 4x / 4
15 = x
x = 15 feets
The area of a shape is the amount of space it can occupy.
<em>The number of isosceles triangle in the grid is: </em><em />
The dimension of the grid is given as:
Calculate the area
The area of each isosceles triangle is given as:
The number (n) of the triangle in an x-by-x grid is:
So, we have:
Express as products
Hence, the number of isosceles triangle in the grid is:

Answer:
B) 3 seconds
Step-by-step explanation:
Speed = Distance / Time
So, Time = Distance / Speed
= 12 / 4 s = 3 s
