Answer:
the standared deviation =2.87 so it is small
Step-by-step explanation:
to calculate the standard deviation of those numbers:
1- Work out the Mean (the simple average of the numbers)
(7+6+5+8+9+1+0+4+3+2)/10=4.5
Then for each number: subtract the Mean and square the result.
[(7 - 4.5)^2 + ... + (2 - 4.5)^2]/10=8.25
√8.25=2.87≅3
Answer:
$ 2,200 for 8%, $ 1,300 for 12%
Step-by-step explanation:
I=PRT
Let Bank 1 be <em>x</em>
332= x (8%) + (3,500-x) 12%
332= x (0.08) + (3,500-x) 0.12 change the percent to decimal
332= 0.08x + 420 - 0.12x
0.04x= 420-332
x= 
x= 2,200 (Bank 1)
Bank 2= 3,500-Bank 1
Bank 2= 3,500- 2,200
Bank 2= 1,300
Step-by-step explanation:
360 - 126 =234
234 ÷3x
x = 78
