Answer- <em>X=12</em>
Step-by-step explanation:
X + 9/7 = 3 is our equation
Then we are going to do the opposite of dividing 7 from 9 which is multiplying 7 from 9. (on both sides)
It will leave us with - X + 9 = 21
Then we will do the opposite of adding 9 to X which is subtracting 9 from X. (also on both sides) ( whenever you do any adding or subtracting or multiplying or dividing on one side you have to do it on the other for the equation to be true)
Now it will leave us with X = 12
And that's our answer! :>
Answer: 

Step-by-step explanation:
- A null hypothesis is a hypothesis where a researcher generally try to disprove, it says that there is no statistically significant relationship between the two variables .

Alternative hypothesis : 
Answer:
The roots are
<h3>

</h3>
Step-by-step explanation:
9x² + 54x + 82 = 0
Using the quadratic formula
That's
<h3>

</h3>
From the question
a = 9 , b = 54 , c = 82
Substitute the values into the above formula and solve
That's
<h3>

</h3>
Separate the real and imaginary parts
That's
<h3>

</h3>
We have the final answer as
<h3>

</h3>
