Answer:
The percentage of customers who buy an extended warranty is 33%.
Step-by-step explanation:
In this problem, we have these following percentages.
35% of the customers select the basic camera.
This also means that:
65% of the customers select the deluxe version. (Since you can buy only two versions of the hard disk camera and the sum of the percentages is 100%).
20% of those who select the basic camera also purchase the extended warranty.
40% of those who select the deluxe version also purchase the extended warranty.
What is the percentage of customers who buy an extened warranty?
is the percentage of those who buy the basic version with the extended warranty. So it is 20% of 35%. So
is the percentage of those who buy the deluxe version with the extended warranty. So it is 40% of 65%. So
The percentage of customers who buy an extended warranty is 33%.
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.

Answer:
7x° + 11x° = 90°
(Required equation)
Step-by-step explanation:
7x° + 11x° = 90°
(complementary angles)
18x° = 90°
18x = 90
x = 90/18
x = 5
