Answer:
millimeters.
Step-by-step explanation:
We have been given that a leak in a water tank causes the water level to decrease by millimeters each second.
To find the decrease in water level in 5 hours let us multiply water decrease in one second by number of seconds in 5 hours.
Using the exponent product rule let us add the exponents with same base (10).
Therefore, the water level in tank decreased millimeters in 5 hours.
Answer:
a ) n = 1667
b) n= 5192
c) n=1500
Step-by-step explanation:
c= 95%
Expected value = E.v= 300 , 170 , 100
R = 35000-10000=25000
σ = R / 4 = 25000 / 4 = 6250
For sample size
b = ( zα/2 / 2σ / E )^2
where 1-α = 0.95 and
zα/2 = 1.96
then putting values one by one of E we get
E.v = 300
n= 1667
E.v = 170
n=5192
E.v =100
n= 1500
so for
a ) n = 1667
b) n= 5192
c) n=1500
