To find the difference between the amount she had yesterday and amount she has today, set it up like this:
Since the terms aren't compatible, we need to convert
into a fraction with a common denominator:
The terms can now be subtracted:
Ruby had
pounds more cinnamon yesterday.
First compute the probability of getting an orange marble.
Number of favorable possibilities: 5.
Number of all the possibilities: 10.
So the probability of getting an orange marble is: 5/10=1/2.
Since the above probability is 50%, then multiply by the 120 experiment in order to get the number of time we expect an orange marble:
Answer: 60 times.
Answer:
3.73
Step-by-step explanation:
To solve this, we simply need to find the mean (or the average) with the addition of the new member. To find an average, we simply add all the values and then divide by the total amount of values. The work is shown below...
(3.7) + (3.7) + (3.7) + (3.7) + (3.7) + (3.7) + (3.7) + (3.7) + (3.7) + (4.0) = 37.3
Now we divide 37.3 by the amount of members, which is 10.
37.3 / 10 = 3.73
The league's new average is 3.73
Hey there!
For this problem, all you need to do is some multiplication:
40 ft per car * 28 cars = 1,120 ft total
30 ft per car * 34 cars = 1,020 ft total
You can see that Train A exceeds the limit, while Train B doesn't.
Hope this helped you out! :-)
