V = 4/3 × 22/7 × (2)³
= 4/3 × 22/7 × 8
= 33.52 ft³

Answer:
5 marbles
Step-by-step explanation:
A bag contains
8 white marbles
6 red marbles
4 blue marbles.
Total number of marbles is :
8 + 6 + 4
= 18 marbles
Based on this current proportion
The Probability of choosing a blue marble = Number of blue marbles/ Total number of marbles
In order for the Probability of choosing a blue marble to be 1/2
The number of blue marbles has to be:
= 18 marbles × 1/2
= 9 blue marbles
From the question we have 4 blue marbles, hence:
9 blue marbles - 4 blue marbles
= 5 blue marbles
Therefore, 5 blue marbles must be added to the bag so that the probability of choosing a blue marble is 1/2.
Answer:
It decreases.
Step-by-step explanation:
10 / d
Lets say that it was 10 / 40, which is 10 divided by 40, 0.25.
Now, it has increased to twice the amount of that.
1 / 80, 10 divided by 80, which is 0.125
So, it decreases.
