Answer:
I think you mean 1/9^2. That would be 1/81 or 0.01234567
.

<span>B)The mean and the median become equal.hope this helps</span>
Answer:
assume it's width as 'x'
So, it's length is '2x-3'
and the perimeter is equal to 66m
Step-by-step explanation:
So,equalize the equation
x + (2x-3) + x + (2x-3) = 66
remove the brackets
2x + 4x - 6 = 66
add 6 to both sides
6x = 60
x = 60 ÷ 6
= 10
so, the length is 2x-3 = 20 - 3 = 17 m
and the breadth is x = 10 m
Its 81.
Median is the middle number.
Rearrange the numbers to smallest to biggest.
70,77,80,_,82,87,88
if the median of the data set is 81 the middle number needs to be 81.
So the missing number is 81.
70,77,80,81,82,87,88
You can rewrite 10n + 6 as 2(5n + 3).
Find a common factor in both 10 and 6, which is 2 and factor the 2 out. 2 times <em>5</em> gives 10 and 2 times <em>3</em> gives 6.
