Answer:
For 135 students , the number of teacher requires is 9
Step-by-step explanation:
Given as :
The number of teacher = 6
The number of student = 90
∵ For 90 students , the number of teacher requires = 6
So , For 1 student , the number of teacher requires = 
= 
∴ For 135 student , the number of teacher requires =
×135
Or, For 135 student , the number of teacher requires = 
So, For 135 student , the number of teacher requires = 9
Hence For 135 students , the number of teacher requires is 9 Answer
To do linear equations, basically, just imagine it with an equals sign. It is pretty much the same as normal algebra, so it's not too confusing.
An example of a linear equation is 3x - 7 = 11
with this, your objective is to get 'x' on its own and to do this, do inverse operations (the opposite to what is actually done)
For instance, to get '3x' on its own, you must add 7.
So do this for both sides to give you
3x = 18
Yeah?
Now you must get 'x' on its own. It currently has 3 x's at the moment, so you must divide it by 3 to give you one 'x'. A rule with these - what you do to one side you must do to the other.
So this means that if you divide 3x by 3, you must divide 18 by 3.
This leaves you with x = 6.
Using <u>probability distribution concepts</u>, the correct option is:
-
C. the sum of the probabilities is not 1.00
- In a probability distribution, the <u>sum of all probabilities has to be equals to 1</u>.
In this problem, the probabilities are: 0.25, 0.45, 0, 0.35.
Their sum is:

Since the <u>sum is not 1</u>, the correct option is:
- C. the sum of the probabilities is not 1.00

Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)
