Hello,
Let's work in dm and dm².
Let's a the shortest side
2a+b=9
ab=10
==>2a²-9a+10=0
==>(a=5/2 and b=4) or (a=2 and b=5)
The rectangle is 25 cm * 40 cm
or 20 cm * 50 cm
Proof:
(25,40)
2*25+40=90 (cm)
25*40=1000 (cm²)
(20,50)
2*20+50=90 (cm)
20*50=1000 (cm²)
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:
There are as many definitions of empire as there have been empires, but some pretty familiar elements appear in most of them. It starts with working on our “control issues”.
The perpendicular slope to y=5/12x+3 is Y = - 12/ 5 x + 8
