Answer:
Step-by-step explanation:
Probability of a head is 1/2 of getting heads.
probability of a number greater than 1 is 7/8 on 8 sided die
Total probability = 1/2 * 7/8 = 7/16 = 0.4375
Answer:
r = -1/2
Step-by-step explanation:
3(5 + 4r) = -18r
15 +12r = -18r by distributive property
15 = -12r - 18r
15 = -30r
r = - 1/2r
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.
