Total numbers=10
mean(average)=14.8
standard deviation=3.4254
variance_standard deviation)=11.73333
population standard deviation=3.24962
variance(population standard deviation)=10.56
Answer:
81x + 4913x + 676x + 10x + 12 / 9
X=5692 /9
X=632.444
The answer is 481.6, because 56% = 0.56, so just multiply 860 by 0.56 and u get 481.6
Hey there!
Let solve this problem step by step :)
1. Convert 20/25 into a decimal. In order to do this, you will need to divide the numerator (the top part of the fraction) with the denominator (the bottom part of the fraction).
So,

as a decimal would be 0.8. (We divide 20 by 25)
2. Now, we take the decimal and multiply it by 100. To make it even simpler, just move the decimal, two places to the right. This makes it the percent. So,
0.8 ----> 80%
The final answer is 80%Thank you!
