Using the given information, the height of the shorter cone is 6.81 cm
<h3>Calculating volume of a cone </h3>
From the question, we are to determine the height of the shorter cone.
First, we will calculate the volume of the first cone
Using the formula for calculating the volume of a cone,

Where V is the volume
r is the radius
and h is the height
From the given information,
r = 8.5 cm
h = 10 cm
Then,


cm³
Now, for the shorter cone
r = 10.3 cm
Since the two cones have the exact same volume, we can write that



h = 6.81 cm
Hence, the height of the shorter cone is 6.81 cm.

The answer to this is 49995.
We can rewrite the asked question like this:

wherein X_1 and X_2 are random variable with the same given normal distribution. Then mean of

is zero and the variance
can be computed like this:

So, the random variable

follows a normal distribution
with means 0 and standard deviation 9.6.
The median of the law N(0,9.6) is 0.
So the expected difference of the score is 0.
Answer:
The answer is 2

Answer:
5 sqrt2.
Step-by-step explanation:
5 sqrt 8 - sqrt 18 - 2 sqrt 2
= 5 sqrt(4*2) - sqrt(9*2) - 2 sqrt2
= 5 sqrt4*sqrt 2 - sqrt 9*sqrt 2 - 2 sqrt2
= 10 sqrt2 - 3 sqrt2 - 2 sqrt 2
= 5 sqrt2.
