Answer:
Substitute
Step-by-step explanation:
Substitute the values given in the function
and you will get the answer.
P.s. It depends on the question
This is the concept of statistics, given that there are 650 students and all of them read a total of 18,996 pages. We are required to get the average number of pages that they all read;
Average, otherwise known as the mean is the calculated 'central' value of a set of numbers;
The formula for mean is given by;
mean=(sum)/(count)
in our case:
sum=18,996
count=650
thus;
mean=18996/650
=29.23
Here we can conclude that the average number of pages read by each student in the High School was 29.23
Answer:
The answer is 3
Step-by-step explanation:
E. 5x^2 - 10= 0; 5(x^2 - 2)= 0; x^2= 2; x = √2
f. x^2 - x=0; x(x -1)= 0; x = 0, x= 1
g. 4x^2 + 4x= 0 ; 4x( x + 1) = 0; x = 0, x = -1
h. -x^2 + x = 0; -x(x - 1)= 0; x = 0, x = 1
