Factor both numbers by finding every number that can be divided evenly out of the number.
The factors for 9 are: 1, 3, 9
The factors for 12 are: 1, 2, 3, 4, 6, 12
The largest factor the two numbers have in common is 3.
First 3/4: this is actually 0.75. but the percent means we have to divide it by 100:
0.0075
3/25 is actually 0.12 (because it's equal to 12/100: i multiplied both numbers by 4)
and if it's a percent, again we "move to "move the point" or in other words divide by a 100:
0.0012 (think of dividing by 10 as of moving the coma to the left and adding zeros if there is noone to move)
the last one is equal to 55/100 (multiplied both by 5), so 11/20 % is 0.0055
I hope this was clear, let me know if you have questions!
First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
Answer:
9% of $8.23=
0.09x$8.23=$0.74 (tax)
$8.23+$0.74=$8.97 (total)
