Answer:
Step-by-step explanation:
The GCF of the group (6x - 3) is 3. The common binomial factor is 2x-1. The factored expression is (7x+3)(2x-1).
I'll give you the answer to 1 one of the questions so you can solve the rest by yourself:
9)4/6 = 16/24
4/8 = 12/24
Answer equals: 16/24,12/24
I hope you get it! All you need to do is "Whatever you do to the bottom(denominator), you do to the top(numerator)!"

Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The number of student is 
The highest amount is 
$200
The lowest amount is 
$75
The sample mean is 
&140
The Standard deviation of this set is mathematically evaluated as
Substituting values
The margin of error (ME) is mathematically evaluated as
Where 
is the critical value for 
i.e the significance level
From the critical value table this is 
So
Answer:
C. In a meeting room for a business event, there are 4 fewer chairs laid out in each row than the number of rows. The total number of chairs in the room is 60.
Step-by-step explanation:
To find the total number of chars, we multiply the number of rows by the number of chairs in each row.
Let the number of rows be x. There are 4 fewer chairs in each row than the number of rows; this gives us (x-4). Together, this gives us
x(x-4).
We know there are 60 chairs; this gives us
x(x-4) = 60
Using the distributive property,
x(x)-4(x) = 60
x²-4x = 60
