Answer:
1000
Step-by-step explanation:
If the number of protesters per minute remains a constant, then you could write the proportion ...
p/12 = 177/2.1
Multiplying by 12 gives ...
p = 12(177/2.1) ≈ 1011.4
Here, minutes are given to 2 significant figures, and the initial count is given to 3 significant figures. The best you can hope for is that your estimate is good to 3 significant figures:
1010 protesters
It is probably sufficient to report the number to 2 significant figures*:
1000 protesters
_____
* Unfortunately, with a number like 1000, the only way you can tell it has 2 significant figures is to report it as 1.0×10³ or 10. hundreds. The trailing zeros are usually not considered significant.
Answer:
1/6 and 16.67
Step-by-step explanation:
Add all the marbles, you get 12.
There's 2 out of 12 yellow marbles so you get 2/12
2/12 simplified to 1/6
So 1/6 is the probability as a fraction
Now to get the percentage just divide 100 by 6.
100/6 equals 16.67
Since it's 1/6 we multiply that by one
16.67 times 1 equals 16.67
