Answer:
609
Step-by-step explanation:
ratio of teachers to students at Priory School =2:27
Let X= total number of both the students and the teacher
Ratio of teacher=( 2/29)X
Ratio of student is (27/29 )X
But total number of teacher = 42
2/29 ×X =42
2X= 42×29
2X=1218
X= 609
Hence, school's total population is 609

Step-by-step explanation:

So, value of s is between -4 and 4, while both -4 and 4 are not included.
Step-by-step explanation:
We need to find the number line that shows the solution set for Absolute Value s/2 less-than 2.
Writing in mathematical form:

Applying absolute rule: |u|<a then -a < u < a

Simplifying:


Combining the intervals we get:

So, value of s is between -4 and 4, while both -4 and 4 are not included.
The number line is shown in figure attached.
