Answer:

5/4 would not fit with the other 3.

Step-by-step explanation:

This is because it is an improper fraction, which is a fraction which is bigger than the value 1. The rest are all less than 1.

Find the probability of picking 4 consonant and 1 vowels when 5 letters are picked (without replacement) from a set of alphabet
Ganezh [65]

The required probability is 0.45

We have total 26 letters in english, of which 21 are consonants and 5 are vowels.

According to the question, we have to select 5 of them of which 4 will be consonants and 1 will be vowel.

Suppose we want to have the vowel in the first selection, so the probability of picking a vowel is equal to the quotient between the number of vowels and the number of total number of letters.

So the probability is 5/26

Now, a letter has been selected, so in the set, we have 25 letters left.

In the next 4 selections, we must select consonants.

In the second selection the probability is 21/25

In the third selection the probability is 20/24

In the fourth selection the probability is 19/23

In the last selection the probability is 18/22

So, the probability is (5/26)×(21/25)×(20/24)×(19/23)×(18/22)

Now, remember that we take that the vowel must be in the first place, but it can be in any five places, so if we add the permutations of the vowel letter we have,

P = 5×(5/26)×(21/25)×(20/24)×(19/23)×(18/22) = 0.45

The graph of y = f(x) is shown. <br> a) Find f(0) <br> 4- <br> 3. <br> b) Give the roots of f(x) = 0
Amanda [17]

The value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1

<h3>Graph of a function</h3>

From the question, we are to determine the value of f(0) and the roots of f(x) = 0

The value of f(0) is the value of f(x) or the value of y when x = 0

In the given graph, we can observe that the value of y when x = 0 is 2

∴ f(0) = 2

The roots of f(x) = 0 correspond to the values of x when f(x) = 0 or when y = 0

In the graph, we can observe that the values of x when f(x) = 0 are -2 and -1

∴ The roots of f(x) = 0 are -2 and -1

Hence, the value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1

What is the greatest common factor between 24 &amp; 28
Elis [28]
24:
1 and 24
6 and 4
2 and 3 2 and 2

So 24 = 1 X 2^3 X 3


28:
1 and 28
7 and 4
2 and 2

So 28 = 1 X 2^2 X 7

Therefore the greatest common factor of 24 and 28 is 2.
