Step-by-step explanation:
Let h = height of water and r = radius of its surface
At all times,
So,
We want![\frac{\text{d}h}{\text{d}t}](/tpl/images/0025/0304/b8405.png)
When h = 8 cm
The depth of the water is decreasing at a rate of
cm³/min
.

The probability that MicroTech will beat the competition with its new computers is 0.994
Step-by-step explanation:
Consider the provided information.
MicroTech has funded three separate design teams to create the new systems.
The Probability of team A will come up with acceptable design is 90% or 0.9
The Probability of team B will come up with acceptable design is 80% or 0.8
The Probability of team C will come up with acceptable design is 70% or 0.7
The probability of non of them will be able to come up with acceptable design = (1-0.9)×(1-0.8)×(1-0.7) = 0.1×0.2×0.3 = 0.006
Thus, the probability that MicroTech will beat the competition with its new computers is:
1-0.006 = 0.994
Hence, the required probability is 0.994
