Answer:
A is correct
Step-by-step explanation:
In this question, we are concerned with. calculating the diameter of a bubble given the volume of the bubble.
Since we have assumed the bubble to be a perfect sphere, it’s volume V = 4/3 * pi * r^3
Plugging the value of V = 1000cm^3 , we have
1000 = 4/3 * pi * r^3
3000/4pi = r^3
r^3 = 238.732
r = cube foot of 238.732
r = 6.20cm
This is same as 6.2cm
Answer:
Option (A)
Step-by-step explanation:
A set of real numbers is a combination of both rational and irrational numbers.
But the elements in the sets of rational and irrational numbers will be different.
In short, rational and irrational number sets are the two subsets of real numbers.
Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.
Option (A) is the correct option.
So you basically want us to answer for u anyway well it’ll be:
For 2< it’ll have to be something greater that two or 2 and then for <5 it’ll be the same so for example if it was like that I’ll do it like this: 3x5=15
Hope That Helped!
Answer:
$4895
Step-by-step explanation:
P(winning) = 1 / 1000000 = 0.000001
P(not winning) = 1 - 1/1000000 = 0.999999
Winning amount = 4,900,000,000 - 5 = 4899999995
Amount lost = - 5
__ X: - 5 _________ 4899999995
P(X) : 0.999999 ___ 0.000001
Expected value E(x) = Σx * p(x)
E(x) = - 5(0.999999) + 4899999995(0.000001)
E(x) = - 4.999995 + 4899.999995
E(x) = 4895
Hence, expected value is 4895
