The answer to this problem is one because nine times one equals nine which the answer is still nine
In order to find the median the 1st thing I would do is put the number in order
80,84,87,88,88,90,90,95,98,100
then cross them out Start with left then go the right and so on...
until you get 1 number in the middle left (Since theirs 2 numbers in the middle add them up and divide by two ) 88+90=178 178/2=89
Median = 89
Now in Order to find the mean add up all the numbers and divide by however many numbers their are
You should get 900 then divide by 10 because their were 10 numbers
So Median=89 & Mean=90
Answer:
48cm
Step-by-step explanation:
take width of rectangle to be=xcm
Length will be 3x
Area of rectangle=length × width
A=3x × x =3x²
3x²=108
x²=108/3=36
x²=36
x=√36=6cm
substitute
lenth=3x=3×6=18
width=x=6cm
perimeter=2l+2w
p=2×18 + 2×6
p=36+12=48cm
Since it’s adding you are gonna do the inverse operation which is subtract so subtract 17 from both sides. You will then get x is less or equal to -20 then u divide both by one
8h + 10 or 10 + 8h
Hope this helps :)
