The probability that the die will roll 2 or 4 is 1 out of 3 or 1/3rd. 1/3rd of 300 is 100 so it is expected that it will roll either a 2 or a 4 100 times.
Answer:
Each slice of bread costs $0.06.
Step-by-step explanation:
To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.
The answer is: D) 115
The explanation is shown below:
1. You have that the frequency with which a cricket chirps varies directly with the temperature, which you can express it as following:
Where is the frequency with which a cricket chirps, is the temperature and is the constant of proportionality.
2. If the cricket chirps 100 times per minute in 80° weather, you can calculate as below:
3. Therefore, the frequency in 92° weather is:
You can notice that 14 is 7 time 2, so the answer is 15*2=30. Also, you can use cross multiplication to find your answer.
