The answer for this problem is39906
A=A₀
A/A₀=24%=0.24
0.24=
0.000121t=ln(0.24)
t=ln(0.24)/0.000121
=-11794.35
so painting is 11794 years old
Simple interest is found by multiplying the amount of money deposited, the rate ( like .05 per month ) , and the time it will be in the bank ( one moth, 5 months, a year, etc. ).
I'm 1000% positive this is correct.
Hope I helped you learn something new today!
Answer:
Step-by-step explanation:
We have,
Mean = Σx/n
or 12= (m+n+s+p+q)/5
or, m+n+s+p+q = 60 ...........(i)
Again,
New Mean = (m+4+n-3+s+6+p-2+q+8)/5 [∵ n = 5]
or, New Mean = {(m+n+s+p+q)+13}/5
or, New Mean = (60+13)/5 = 73/5 [from eq (i)]
∴ New Mean = 14.6 Ans.
