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
Answer:
The answer is (6,9)
Step-by-step explanation:
We simply need to find two numbers that perfectly fits the equation. That is, 2 numbers in which when we substitute the value for x and y works perfectly.
First option is wrong.
3x + 2y = 36
Here, x = 6 and y = 0
Hence, 3(6) + 2(0) = 18 which is wrong.
3rd option is wrong
Here x = 6 and y = -9
3(6) + 2(-9) = 0
Last option is wrong
Here x = 6 and y = 6
3(6) + 2(6) = 18 + 12 = 30.
2nd option is correct
Here x =6 and y = 9
3(6) + 2(9) = 18 + 18 = 36
Answer:
starts wuth 46, and sells half, so she has 23. then when she buys 17 more she then has 40.
if you are asked to show work its 46/2=23, then 23+17=40!
