There are 20 and 2 green 20-2 is 18 so 18/20 simplified is also 9/10
Answer:
78 quarters
Step-by-step explanation:
I think because, I created an equation, 5x = 390 and solves to get 78
The answer in this question is A, D and E, we might conclude if a random sample of 36 time interval between eruption has a mean longer that 104 minutes, I can conclude that the population means may be greater than 91 and the probability mean must be more that 91, since the probability is low and also the population mean is 91, and this is an example of a typical sampling result.
The answer is:
B. The cost for a group of friends to see a movie compared to the number of friends.
We can tell that this is most likely to have a constant rate of change because of what we already know about movie prices.
Movie prices are fixed, therefore, no matter how many friends you bring, the total price will always go up by the same amount.
For example:
Let's say a movie ticket costs $5 and you brought 3 friends with you. Since there are 4 people in total, you'd have to pay $20 for the tickets (5x4=20). Just as you're about to pay, Sally shows up. Now you have to pay for 5 people in total. How much do you need to pay now?
You will now need to pay $25 (5x5=25) for all of the tickets. Even though you now have 5 people in the group, you still only have to pay $5 for each ticket.
This is an example of a constant rate of change.
