Answer:
Step-by-step explanation:
If you have two matrices:
We have:
The sum between the two matrices is:
Answer:
So the answer for this case would be n=247 rounded up to the nearest integer
Step-by-step explanation:
We know that the standard deviation is :
represent the deviation
The margin of error is given by this formula:
(a)
And on this case we have that ME =25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 95% of confidence interval now can be founded using the normal distribution and the critical value would be , replacing into formula (b) we got:
So the answer for this case would be n=247 rounded up to the nearest integer
Answer:
11984.18 dollars
Step-by-step explanation:
Given that an amount of 5700 dollars is invested at 11.2% p.a. for seven years compounded.
We have compound interest formula for Principal P for n years at r% compounded annually is
Final amount =
Final amount for 5700 dollars at 11.2% p.a. for 7 years would be
11984.18 dollars.
Answer is 11984.18 dollars
We know that
<span>ρ = density of gasoline = 737 kg/m³ (at T = 60°F = 15.6°C)
</span>ρ = m/V
ρV = m
V = m/ρ
V = 49.0 kg / 737 kg/m³
<span>V = 0.066 m³
[volume of the tank]=L*W*H-----> H=volume/[L*W]----> H=0.066/(0.9*0.4)
H=0.1833 m
the answer is
t</span><span>he depth of the tank is 0.18 m</span>
