The correct answer is $3. Please mark me brainiest. :)
Answer:
5
Step-by-step explanation:
Given that :
Miles ridden in Tuesday = 10
Miles ridden on Wednesday = 20
Sample size, n = 2
Mean :
(10 + 20) / 2
= 30 /2
= 15
Mean absolute deviation :
(|10 - 15| + |20 - 15|) / 2
(5 + 5) / 2
10 / 2
= 5

Answer:

Step-by-step explanation:
Water is being pumped into an inflated rubber sphere at a constant rate of 0.03 cubic meters per second.
So, dV/dt = 0.03.
We want to show that dS/dt is directly proportional to 1/r.
In other words, we want to establish the relationship that dS/dt = k(1/r), where k is some constant.
First, the volume of a sphere V is given by:

Therefore:

Next, the surface area of a sphere S is given by:

Therefore:

We can divide both sides by 2:

We can substitute this into dV/dt. Rewriting:

So:

Since dV/dt = 0.03 or 3/100:

Therefore:

Where k = 3/50.
And we have shown that dS/dt is directly proportional to 1/r.
