Let's say we wanted to subtract these measurements.
We can do the calculation exactly:
45.367 - 43.43 = 1.937
But let's take the idea that measurements were rounded to that last decimal place.
So 45.367 might be as small as 45.3665 or as large as 45.3675.
Similarly 43.43 might be as small as 43.425 or as large as 43.435.
So our difference may be as large as
45.3675 - 43.425 = 1.9425
or as small as
45.3665 - 43.435 = 1.9315
If we express our answer as 1.937 that means we're saying the true measurement is between 1.9365 and 1.9375. Since we determined our true measurement was between 1.9313 and 1.9425, the measurement with more digits overestimates the accuracy.
The usual rule is to when we add or subtract to express the result to the accuracy our least accurate measurement, here two decimal places.
We get 1.94 so an imputed range between 1.935 and 1.945. Our actual range doesn't exactly line up with this, so we're only approximating the error, but the approximate inaccuracy is maintained.
You can solve the median by putting all the numbers in order. Then cross off one at a time at the start, then cross off the one at the end, then keep going until you get to one.
You can solve the mode by looking for the most frequent number. I remembered that by looking at mode and seeing MO and remembering most often.
I hope this helps :-)
In every case the larger number is rounded up to 2E13.
Divide this by 3E8:
2E13 = 200000E8
-------- --------------- is approx equal to 70000 (dollars).

Answer: B
Step-by-step explanation:
If you divide the word by minutes for each one you get 216 which is for the record speed and if you divided how fast Charlie typed it would be 140 which mean that Charlie types slower then the record speed
