Answer:
B
Step-by-step explanation:
An experiment is a study carried out in a controlled environment where the person undertaking the research hopes to understand cause and effect between the independent and dependent variables. An example of a experiment is the palovian experiment
The independent variable is the variable that the person carrying out an experiment changes or manipulates. the independent variable usually have a direct effect on the dependent variable
The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable
Observational study is the study where the researcher observes and measures cause and effect between independent and dependent variables without trying to control or influence the population
The "product" of two numbers means you multiply them.
So, you are multiplying (8-n), where n = "a number," by 7.
Then, when you decrease (subtract) this product by 5, you get 40.
So the whole thing looks like
7(8-n) - 5 = 40.
Answer:
Step-by-step explanation:
Answer:
The equation showing this situation is 
Step-by-step explanation:
Given : A quadratic equation of the form 
has one real number solution.
To find : Which could be the equation?
Solution :
A quadratic equation in form 
has a solution 
called a quadratic formula in which the roots are one real,two real or no real is determine by discriminant factor.
Discriminant is defined as to determine the number of roots in a quadratic equitation has following rules :
1) If 
there are two real roots.
2) If there are one real roots.
3) If 
there are no real roots.
According to question,
A quadratic equation of the form has one real number solution.
So, The equation showing this situation is
