Answer:
<h3>Greater than 20</h3>
Step-by-step explanation:
Since mean is the average number of students, the formula for calculating the mean attendance of students is expressed as;
Mean = total number of student/sample size
![\overline x = \frac{\sum Xi}{N}](https://tex.z-dn.net/?f=%5Coverline%20x%20%3D%20%5Cfrac%7B%5Csum%20Xi%7D%7BN%7D)
Given mean = 20
Since the question talks about the first four meetings, the sample size = 4
![20 = \frac{\sum Xi}{4}\\ \\\sum Xi = 20 * 4\\\\\sum Xi = 80](https://tex.z-dn.net/?f=20%20%3D%20%5Cfrac%7B%5Csum%20Xi%7D%7B4%7D%5C%5C%20%5C%5C%5Csum%20Xi%20%3D%2020%20%2A%204%5C%5C%5C%5C%5Csum%20Xi%20%3D%2080)
<em>Since the sum total of students for the first four meetings is 80, hence the number of students who attended the meeting is greater than 20</em>
Synthetic division work with the coefficient of the given polynomial expression
We have
-15 -16 84 -17 -9 -15
and the divisor is:
x - ⁸/₅ = 0
x = ⁸/₅
Refer to the diagram below for the steps of synthetic division
Start by multiplying the first coefficient by the divisor, write the answer under the second coefficient, and then add the two values.
Repeat the steps until we use up all the remaining coefficients
The final values are the coefficients of the quotient and the last value is the reminder
