From the distribution, it seems as though the digits at fairly even frequencies, though we can test our intuition by doing a few calculations.
The mean (or average) frequency can tell us quite a bit here, and we can calculate it by adding together all of the frequencies and then dividing by the number of frequencies (in this case, 10, since we have 10 digits)
Doing that, we find
(1 + 4 + 5 + 7 + 4 + 5 + 2 + 3 + 5 + 5)/10 = 41/10 = 4.1
When we divide the number of digits (40) by 4.1, we find it equals roughly 10, which means that, *on average*, each of the 10 digits appeared about 4 times. With this knowledge in hand, it wouldn’t be too out-there to suggest that this distribution is going to tend to even out more and more as we continue to add further decimal approximations of π

<h3>What is inequality?</h3>
A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
|x +2 | <-3
If we take the module is positive,
x+2 -2 < -3-2
x < -5
If we take the module is negative,
-( x+2) < -3
-x -2 < -3
-x -2 +2 < -3 +2
-x< -1
x>1
Combining the inequalities,
-5<x<1

I believe that it is “Sakura walks 6 miles every day”
Answer:
1km= 1000m= 1.0 x10^5 cm
28km x 1.0 x10^5 cm= 2.8 x10^6 cm
Step-by-step explanation:
8/9 divided by 2/9
is equal to the expression
8/9 times 9/2
~~~~~~~~~~~~~cross this line to solve~~~~~~~~
multiply both the numerators and the denominators together
(8*9) (9*2)
you will get 72/18
which is simplified to 4
