Question:
The probability of a certain brand of battery going dead within 15 hours is 1/3. Noah has a toy that requires 4 of these batteries. He wants to estimate the probability that at least one battery will die before 15 hours are up.1.Noah will simulate the situation by putting marbles in a bag. Drawing one marble from the bag will represent the outcome of one of the batteries in the toy after 15 hours. Red marbles represent a battery that dies before 15 hours are up, and green marbles represent a battery that lasts longer.How many marbles of each color should he put in the bag? Explain your reasoning.
Answer:
The number of marbles of each color that should be present in the bag is;
1 red marble and 2 green marbles
Step-by-step explanation:
Here, we note that the probability of a battery going dead = 1/3 and the
Therefore if the red marbles represent that a battery dies before 15 hours then the probability of picking the red marble should be 1/3. That is if there is only one red marble in the bag, the probability of picking the red will be 1/3 when there are other 2 green batteries in the bag
That is there should be 1 red marble and 2 green marble in the bag.
Step-by-step explanation:
let the total students be x then
25/100x=9
x=9×100/25
x=9×4
x=36
so total students are 36
Answer:
V = 8491 mm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is 13 and the height is 16
V = pi * (13)^2 *16
V = 169*16 *pi
V =2704 *pi
Let pi be approximated by 3.14
V =2704(3.14)
V =8490.56
To the nearest whole number
V = 8491 mm^3
