Answer:
No, It is a Cluster Sampling.
Step-by-step explanation:
Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.
If the population is divided into a different group called cluster and clusters are selected as a sample then it is Cluster Sampling.
Here, since Expert is interviewing all of the teachers at the selected schools, so it is Cluster Sampling, not a Simple Random Sampling.
Answer:
Yes a number in a sequence is a term.
Step-by-step explanation:
Suppose we have three terms n+2 , n+4 and n+6 in the sequence .
These are treated as separate terms .
Suppose we have
n+ 2= 32
n+2-2= 32-2
n= 30
Again if we put
n+4=32
n+4-4= 32-4
n= 28
we get different values of n for the one solution given for all terms which shows that each term is different.
Now
if we have a different solution for each of them then
Putting the values
n+ 2= 32
n+2-2= 32-2
n= 30
Which shows n is constant but still the terms are different as each has a different value.
Hence the given number in a sequence is a different term.
and
n+4=34
n+4-4= 34-4
n= 30
- Modulus function is a function gives absolute value of a number or variable.
- It gives magnitude of the number or variables.
- It is also known as an absolute value the function.
- The result of this modulus function is always positive.
Draw the graph:
f(x) = |x-1|
f(x) = -(x-1) when x-1 is negative
f(x) = (x-1) when x-1 is positive
when x = -2, f(x) = 3
when x = -1, f(x) = 2
when x = 0, f(x) = 1
when x = 1, f(x) = 0
when x = 2, f(x) = 1
Using this values, draw the graph of f(x) = |x-1|
Hence, the required modulus of x-1 graph.

<span>V(h 24) = 30 cm*20 cm*24 cm = 14400 cm³ = 14,4 liters</span>
<span>V(h 15) = 30 cm*20 cm*15 cm = 9000 cm³ = 9 liters</span>
<span> + 6,5 liters = + 6500 cm³ </span>
9 liters + 6,5 liters = 15,5 liters => 15,5 liters -14,4 liters = 1,1 liters
now 15500 cm³ => 1100 cm³ =1,1 liters too much !!

Ok, I'm only in 8th grade but I believe you do addition first in the problem. Hope this helps! <3
