<h3>(14, 20) is the ordered pair of the function f(x)</h3>

Solution:

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x), we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)

Is 1/3, 2/3, 4/3, 8/3, 16/3 arithmetic sequence

The given sequence is not arithmetic sequence

Solution:

Given sequence is:

$\frac{1}{3} , \frac{2}{3} , \frac{4}{3} , \frac{8}{3} , \frac{16}{3}$

We have to find if the above sequence is arithmetic sequence or not

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant

Here in the given sequence

$\text{ first term } = a_1 = \frac{1}{3}\\\\\text{ second term } = a_2 = \frac{2}{3}\\\\\text{ third term } = a_3 = \frac{4}{3}\\\\\text{ fourth term } = a_4 = \frac{8}{3}\\\\\text{ fifth term } = a_5 = \frac{16}{3}$

Let us find the difference between terms

$a_2 - a_1 = \frac{2}{3} - \frac{1}{3} = \frac{1}{3}$

$a_3 - a_2 = \frac{4}{3} - \frac{2}{3} = \frac{2}{3}$

$a_4 - a_3 = \frac{8}{3} - \frac{4}{3} = \frac{4}{3}$

$a_5 - a_4 = \frac{16}{3} - \frac{8}{3} = \frac{8}{3}$

Thus the difference between terms is not constant

So the given sequence is not arithmetic sequence

Find the missing probability in the table below.

Alla [95]

X 1 2 3 4
p(x) 0.40 0.20 0.15 ?

If the items are only 4. The total of the probability must be 1 or 100%

1 - 0.40 - 0.20 - 0.15 = 0.25

The probability of 4 is 0.25.

A psychology class consists of 14 males and 36 females. if the professor selects name from the class list using random sampling,

Pavel [41]

The total number of students is 14+36, or 50. So the chance that a selected student is female is 36/50, or 18/25.
