we have the function

P(x)=\ln\left|4x+1\right|+3x-x^2

For x=2

substitute

\begin{gathered} P(x)=\operatorname{\ln}\lvert4(2)+1\rvert+3(2)-(2)^2 \\ P(x)=\operatorname{\ln}\lvert9\rvert+2 \\ P(x)=4.20\text{ millions of dollars} \end{gathered}

therefore

Answer:

The questions are

  1. What does the frequency column in the attached table sum to?
  2. What does the relative frequency column in attached table  sum to?
  3. What is the difference between relative frequency and frequency for each data value  in the attached table?
  4. What is the difference between cumulative relative frequency and relative frequency  for each data value in attached table?

The correct answers are

  1. 65
  2. 1
  3. The relative frequency gives the relative proportion of each frequency in the sample while
  4. The frequency is the observed number of count of each grouping has in a given sample size

Step-by-step explanation:

1. The frequency column in the attached column sums up to 65 because it is the total number of sales persons selected

2. The relative frequency column in the attached table sum up to 1 because it is the sum of the fractions of the individual frequencies to the total frequency

Complete the following table
kiruha [24]

The frequency of A's would be 16.

The following would be the relative frequencies after the initial .08.

.18, .45, .15, .14.

To find the frequency of A, start by subtracting all of the other values from the total number. There are 200 total students, so subtract the other grade ranges.

200 - 36 - 90 - 30 - 28 = 16.

Now to find all of the frequencies, just divide each value by the total (200).

36/200 - .18

90/200 = .45

30/200 = .15

28/200 = .14
