Step-by-step explanation:
You need to upload a picture and i can answer underneath.
Usually if measured in feet then we have a scale = 1cm -1ft maybe.
so if you measure 3cm x 4cm then we have 12cm area = 12ft area if. Or if you have 2cm x 5cm = 10cm area = 10ft area if you have 4cm x 5cm = 20cm = 20ft area
etc. etc. Just make sure you say cm then ft in scale conversion.
13, -7, -1, 0, <, >, 66, -12
X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8
Step-by-step explanation:
a+b=41
let larger number be a and smaller be b
a=21+b
placing value of a in a+b=41
21+b+b=41
2b=41-21
b=20÷2
b=10
so a=21+10
=31
Answer:
There are many centeral tendancy like in pie charts, data handling etc. But i think ur asking abt this.. -
- Mean : It is the average ex : 5,5,2 : 5+5+2 /3 = 4
- Median: the middle number (arrange in asc or des order) then find the middle num if there are 2 middle num then find the mean of the 2
ex : 3,4,1,2,5 : 1,2,3,4,5, the middle is 3
-Mode : It is the data that is happening the most frequent
ex: 1,2,2,3,3,3,4,4,5 : 3
Ihope this is usefull !
