34/7
Stanines of 1,2, and 3 are below average, 4, 5, and 6 are average, and 7, 8, and 9 are above average.
Answer is Square-root(14) or approximately +/-3.74. Explanation: To find the standard deviation, you must first find the mean of the population. In this case, the mean is (3+6+12)/3 = 21/3 = 7. Then, we take the Square root of (average of the Squares of (mean - each number)). = Square-root of ( [ (7-3)^2 + (7-6)^2 + (7-12)^2 ] / 3 ) = Square root of ( [ 16 + 1 + 25 ] / 3 ) = Square root of (42 / 3) = Square root of (14)
STOP - This seems to be a homework assignment.I strongly suggest you try to do it first, so that you gain the value of the lesson.The prime factors of 4725 are 3, 3, 3, 5, 5, and 7.Combining these in all of their combinations, along with 1 which is always a divisor, the divisors of 4725 are ...1 (1)3 (3)5 (5)7 (7)9 (3 3)15 (3 5)21 (3 7)25 (5 5)27 (3 3 3)35 (5 7)45 (3 3 5)63 (3 3 7)75 (3 5 5)105 (3 5 7)135 (3 3 3 5)175 (5 5 7)189 (3 3 3 7)225 (3 3 5 5)315 (3 3 5 7)525 (3 5 5 7)675 (3 3 3 5 5)945 (3 3 3 5 7)1575 (3 3 5 5 7)4725 (3 3 3 5 5 7)... so, there are 24.
This is how you do it, there are 7 letters in average so it would be, 7x6x5x4x3x2x1.
Average = (12 + 8 + 7)/3 = 27/3 = 9
The average is 8.
Average = (4 + 6 + 11)/3 = 21/3 = 7
6+8+7= 21 21/3 = 7 The average is 7.
The average height of a window is 3'-7" and the width is 3'.
It is: 8+7+7+5+3+2+2 = 34/7 => 4 and 6/7 which is the average mean
Average = (7 + 14 + 12) / 3Average = 33 / 3 = 11
It is 5+7+12 = 24/3 = 8 which is the mean average
5.4
The average is 5.
Mean = average.
3+7+2+8+10 = 30 30 ÷ 5 = 6 Average = 6
