To identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.
In a research study, there are typically two main variables that direct the scientific enquiry. They are:
- Dependent Variable, and
- Independent Variable
The independent variable causes a change in the dependent variable, i.e. the dependent variable receives the <em>effect</em>, the independent variable is the <em>cause </em>of the change.
It is very easy to identify the dependent variable in any testable hypothesis once you are able to pick out which variable is causing a change in the other.
For example, let's say the topic of a research is: <em>The Impact of Sunlight on Germination Rate of Seedlings.</em>
Here, <em>Sunlight </em>is the independent variable affecting <em>Germination Rate</em>.
The dependent variable here would be: <u><em>Germination Rate.</em></u>
Therefore, to identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.

Answer:
x=5
Step-by-step explanation:
We can write ratios to help us solve
4x 12 +3
---------- = ------------
3x+1 12
Using cross products
4x*12 = (3x+1) * (15)
48x = 45x +15
Subtract 45x from each side
3x =15
Divide by 3
3x/3 =15/3
x=5
Answer:
![3,462\ bacteria](https://tex.z-dn.net/?f=3%2C462%5C%20bacteria)
Step-by-step explanation:
In this problem we have a exponential function of the form
![y=a(b^x)](https://tex.z-dn.net/?f=y%3Da%28b%5Ex%29)
where
x is the time in hours
y is the numbers of bacteria
a is the initial value
b is the base
r is the rate of growth
b=(1+r)
we have that
![a=3,000\ bacteria](https://tex.z-dn.net/?f=a%3D3%2C000%5C%20bacteria)
For x=8, y=3,300
substitute in the exponential function
![3,300=3,000(b^8)](https://tex.z-dn.net/?f=3%2C300%3D3%2C000%28b%5E8%29)
solve for b
![1.1=(b^8)](https://tex.z-dn.net/?f=1.1%3D%28b%5E8%29)
![b=\sqrt[8]{1.1}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B8%5D%7B1.1%7D)
![b=1.0120](https://tex.z-dn.net/?f=b%3D1.0120)
Find the value of r
![r=b-1=1.0120-1=0.0120=1.20\%](https://tex.z-dn.net/?f=r%3Db-1%3D1.0120-1%3D0.0120%3D1.20%5C%25)
The equation is equal to
![y=3,000(1.012^x)](https://tex.z-dn.net/?f=y%3D3%2C000%281.012%5Ex%29)
For x=12 hours
substitute the value of x in the equation
![y=3,000(1.012^{12})](https://tex.z-dn.net/?f=y%3D3%2C000%281.012%5E%7B12%7D%29)
![y=3,462\ bacteria](https://tex.z-dn.net/?f=y%3D3%2C462%5C%20bacteria)
Answer:
k is 16 so now u would plug it in.
Step-by-step explanation:
3 is 65 and 9 is 65 because they are alternate interior angles
2.456 x 10^11= 245600000000
