Forty people were randomly sampled and surveyed as to the number of pets in their household. the results are listed below.

what is the mean, median, and mode of the household pet data?
a.
1.4, 2, 1
c.
1.5, 1, 0
b.
1.5, 2, 1
d.
1.4, 1, 0

Mean=1.4

Median=1

Mode=0

Step-by-step explanation:

We will make the frequency table based on our data as:

Number of Pets                 Frequency

  0                                           15

   1                                           10

   2                                           6

   3                                           4

   4                                           3

   5                                           2

Hence, the mean of the data is calculated as the ratio of sum of all the data point to the number of data points.

Hence,

Hence, Mean=1.4

Now the median is calculated as cumulative frequency.

Number of Pets     Frequency            

      0                            15                         15

       1                           10                     15+10=25

       2                            6                      25+6=31

       3                            4                       31+4=35

       4                            3                       35+3=38

       5                            2                      38+2=40

i.e. N=40

N/2=40/2=20

Hence, the value that lies in this range is: 25

Hence, Median=1

Also mode is the value corresponding to highest frequency.

Hence,  Mode=0

i believe it's a.

i'm not sure on this one, most likely correct.

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
