Answer:
240g in the ratio of 5:3:4
So we need to divide it evenly.
First add up all the ratios.
5+3+4= 12
Now divide 240 by the sum.
240/ 12 = 20
Now you multiply that into each ratio.
5*20 = 100
3*20 = 60
4*20 = 80
Now put it back in the ratio with the new numbers int he exact order as before.
Final Answer: 100 : 60 : 80
Check:
You can check by adding them all up to see if they all go into 240 OR you can divide them each by the number originaly given and you should get 20.
100 + 60 + 80 = 240
100 / 5 = 20
60/3 = 20
80/4 = 20
What are the statement options? If I had to guess it would be Jacqueline practiced 150 minutes all week and Cassie practiced 110 minutes so Jacqueline practiced more minutes in fewer sessions than Cassie.
Answer:
120 feet of fence is enough for a circle 38 feet in diameter
We have the frequencies for each of the grades. We can estimate the number of students graded by adding all those frequencies. Let's call N the total number of grades:
We have then a total number of grades of 39.
The corresponding relative frequency for a grade is the ratio of the frequency to the total number of "samples", 39 in this case.
Then, for grade A, the relative frequency (RF) will be:
This will be the fraction of the total grades that are A. Represented as a percentage will be 10.26%, rounded to two decimal places.
Now, to complete the table we do the same for the other frequencies:
For grade B:
For grade C:
For grade D:
For grade F:
There is no ones place after the decimal so 3 is in the tenth place, so 2.4
