Which of the following is the function F(x) if F^-1(x) = x+4/11?

Marianna [84]

Answer:

B. F(x) =X-4/11

Step-by-step explanation:

We are given the inverse function;

f^(-1)(x) = x + 4/11

Thus means, x was replaced with y and vise versa. Thus;

x = y + 4/11

Lets make y the subject;

y = x - 4/11

Thus,in inverse of a function we replace y with f(x) for the original function or f^(1)(x) for the inverse.

Thus, putting f(x) for y gives;

f(x) = x - 4/11

Lonna gave away 13/8 pie to her neighbor. Each pie was cut into 8 pieces. How many pieces of pie did lonna give to her neighbor

tankabanditka [31]

Answer:

13 pieces

Step-by-step explanation:

We are given that each pie was cut into 8 pieces .

therefore 1 pie is equal to 8 pieces

1 pie = 8 pieces

Lonna gave 13/8 pie to her neighbor .

So multiply both sides with 13/8 in the above equation in order to make the right side into 13/8 pie and to find the corresponding number of pieces .

1× $\frac{13}{8}$ pie=8× $\frac{13}{8}$ pieces

$\frac{13}{8}$ pie = 13 pieces

morpeh [17]

The question is incomplete. Here is the complete question.

Every year, the students at a school are given a musical aptitude test that rates them from 0 (no musical aptitude) to 5 (high musical aptitude). This year's results were shown in the figure below.

The average (mean) aptitude score:

The median aptitude score:

Answer: mean: 2.73

median: 3

Step-by-step explanation: Mean is the average number of a set of numbers.

The table below shows a frequency of students to each score of the test. To calculate mean with a frequency table, do the following:

$mean=\frac{\Sigma (score*frequency)}{\Sigma frequency}$

$mean=\frac{0*1+1*5+2*0+3*3+4*3+5*3}{1+5+0+3+3+3}$

mean = 2.73

Median is the middle term of a set of data.

When there is a frequency table, median is calculated as:

1) First, determine the total number of observations (n).

For this table, n = 15

2) Because n is odd, find the position of the median using:

$position=\frac{n+1}{2}$

position = 8th

3) The median will be in the 8th position. To find the position, we add the frequencies and in doing so, we notice the position we want is in the score 3 category. So, the median for this frequency table is 3.

Average score of a musical aptitude test is 2.73 and median is 3

Write an inequality to represent all combinations of numbers whose sum is greater than 10.

Vlada [557]

Answer:

x>10

Step-by-step explanation:

What this is saying is the variable "x" is any number.

To then make it an inequality im using the greater than symbol (not to be confused with greater than or equal to symbol)

So this means if x= "any number" and has a greater than symbol.

"any number" is greater than 10.
