Answer:
A. 26
Step-by-step explanation: there is 16oz in every lb. so 16 X’s 7=112 now minus the 8ozs used. 112-8=104 oz’s left. The snack bags are 4 ozs so you Divide 4/104=26
13.5·18=243
Base* Hight= Answer
Step-by-step explanation:
slope=4-6/8-3=-2/5
chosing another point (x,y) we have
y-4/x-8= -2/5
y-4=-2/5(x-8)
y= -2/5x+16/5+4
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:
