The answer to this question is true. Based on my knowledge and research, the deviation is, in fact, the difference between any value and the mean of the entire set.
Step-by-step explanation:
You have $7,000 in your savings account gaining 4% interest per year. If you don't replace the $800 in the savings account
<span>15x-3y=27
5x+4y=14
multiply (2nd) equation by (3)
15x + 12y = 42
</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
y = 1
15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
x = 2
so now you have x = 2, y =1

Answer:
$ 9
Step-by-step explanation:
Simple Interest = P.R.T / 100
P = Principal (Amount invested) =$30
R = Rate= 10%
T = Time = 3 years
Therefore, Simple Interest (I):
I = PRT/100
I = ($30 * 10 * 3 ) / 100
I = $900 / 100
I = $9
She will have a total of $9 in three years
