Answer:
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

Answer:
<h2>
A. 1 and 1
</h2><h2>
D. 6 and 1/6
</h2><h2>
E -4/7 and -7/4</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Which pairs of numbers represent a number and its reciprocal?
A. 1 and 1
B. 2/3 and -3/2
C. 1/2 and 5
D. 6 and 1/6
E -4/7 and -7/4
Reciprocal of a number is simply 1 divided by such number. For example the reciprocal of a is 1/a where is any number.
Based on the definition, the following pair of numbers represent a number and its reciprocal
1 and 1
The reciprocal of 1 is 1/1 which is equal to 1
6 and 1/6;
Since I can divide 1 by 6 to get 1/6 , this means that 1/6 is the reciprocal of 6. The pair 6 and 1/6 therefore represent a number and its reciprocal.
-4/7 and -7/4
reciprocal of -4/7 will be 1/(-4/7) = 1 * 7/-4 = -7/4. This shows that -7/4 is the reciprocal of -4/7 hence -4/7 and -7/4 represents a number and its reciprocal.
The answer is eight and one.
Sum: 8 + 1=9
Product:8*1=8
