For problem 17, if you double the diameter of the moon, then the surface increases by a factor of 4 and the volume by a factor of 8.
<h3>
How to compare the change in surface and volume?</h3>
Let's answer question 17.
Remember that for a sphere of radius R, the volume is:
And the surface area is:
So the volume depends on the cube of the radius and the surface on the square of the radius.
Now, if we double the diameter of the moon, then we also double the radius.
So the new volume will be:
The new volume is 8 times the original volume.
And for the surface:
So the new surface is 4 times the original surface.

The 520 is the new thing added to the equation, which makes it equal to the new weight room's size.
Answer:
4560 seconds are in 76 minutes
Step-by-step explanation:
Note that there are 60 seconds in 1 minute. You are solving for 76 minutes. Multiply 76 to 60:
76 x 60 = 4560
4560 seconds are in 76 minutes

Answer:
The parameters of this exponential distribution is = .
Step-by-step explanation:
We are given that the random variable X is known to be exponentially distributed and let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes.
<u><em>So, X = time it takes for a person to choose a birthday gift</em></u>
The probability distribution function of exponential distribution is given by;
where, = parameter of distribution.
Now, the mean of exponential distribution is = which is given to us as average value of 27 minutes that means .
So, X ~ Exp( ) .
Therefore, the parameter of this exponential distribution is .
