The frequency table below, shows the results of a survey of students who have pets. Use the frequency table below to answer the following questions. Round to the nearest tenth, if necessary. .

Step-by-step explanation:

1). Number of students in the survey = Total of frequencies

                                                            = 3 + 5 + 4 + 6 + 3 + 1

                                                            = 22

2). Range of number of pets = 6 - 1 = 5

3). Number of pets most student have = Highest frequency of the number of pets

                                                                = 4 pets

4). For the median number of pets,

   Arrange the frequencies in the increasing order,

   1, 3, 3, 4, 5, 6

   Since number of terms are even, median of the data will be the average of middle two terms.

   Middle terms of the frequencies are 3 and 4.

   Therefore, average of these numbers =

   Therefore, median number of pets = 3.5

a

explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal
