The number 474 rounds to 500. If the number was greater than or equal to 450 it would be rounded to 500 But if the number was less than 450, it would be rounded down to 400.
It depends on if ur rounding to tens or hundreds.
If u were rounding to tens then the number 474 would be rounded to 470. If the number in the one's place was less than 5, it would be rounded to 470. If the number in the one's place was greater than or equal to 5, it would be rounded to 480. Hope this helps and can I get brainliest answer!
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.
