OPTION A
Answer:
or
Step-by-step explanation:
step 1
Find the radius of the circular base of the cone
The volume of the cone is equal to
we have
substitute
simplify pi
step 2
Find the volume of the hemisphere
The volume is equal to
we have
----> is the same that the radius of the cone
substitute
step 3
Find the volume of the solid shape
we know that
The volume of the solid shape is equal to the volume of a cone plus the volume of a hemisphere
so
Convert to mixed number

Answer:
Step-by-step explanation:
Given that the proportion of murders with firearm is 79.2 %
Each murder is independent and there are two outcomes either with fire arm or without fire arm.
Hence X no of murders with fire arm is binomial with n = 200 and p = 0.792
q=1-0.792 = 0.208
a) Expected value of x = np
b) P(X=173) = 0.002289
Since probability is very low it can be concluded it would be unusual to observe 173 murders by firearm in a random sample of 200 murders
290
There's 2 hundreds = 200
Then you have 9 in the tens digit.
The only possible answer for the one's digit is 0 since 0 + 9 = 9.
So the answer is 290.
