You started with a total of 28 muffins
<h3>How to determine the amount you started with?</h3>
From the question, the given parameters are:
Proportion carried away = 16 of the total muffins
Proportion carried away = 4/7 of the total muffins
The above parameters implies that
4/7 of the total muffins = 16
Represent the amount you started with x
So, we have the following representation
4/7 of x = 16
Express as products
4/7x = 16
Make x the subject
x = 7 * 16/4
Evaluate
x = 28
Hence, the total number of muffins is 28

Answer:
Step-by-step explanation:
Hello!
In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.
In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.
If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n
For the students that received the phone call:
n= 19 + 9= 28
The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68
The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32
For the students that didn't receive the phone call:
n= 8 + 6= 14
The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57
The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43
I hope this helps!
If you have two terms in a sequence, then a term decreased by the previous term=common difference
so
30 and 27
27 decreased by 30 is -3
the common differce is -3
Formula is Area/ Pie
78.5/3.14 = 25
