Answer:
dh/dt = 0,07 ft/min
Step-by-step explanation:
The swimming pool has the shape of right circular cylinder, therefore its volume is
V(c) = π*x²*h
Where x is the radius of the base and h the height
We take differentiation on both sides of the equation to get:
dV/dt = π*x²*dh/dt
The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.
Then:
8 = π*x²*dh/dt
dh/dt = 8 / π*x²
dh/dt = 8/113,04
dh/dt = 0,07 ft/min
Answer:
Answer: The total cost is assuming the cost for 1 adult is and the cost for 1 child is
Step-by-step explanation:
Answer:
0.07
a. the distribution will be a normal distribution.
c. we would suspicious ins there is a 2 % chance of getting the required value.
Step-by-step explanation:
Let the number of times, t be = 50
Assuming that the die is fair
standard deviation = 1.71
mean = 3.5
suppose we want tp find the probability of a 2 showing. The solution becomes:
probability = 
c. the mean of rolls will be 0.07
