Answer:
Dependent variable
Step-by-step explanation:
The outcome variable (usually Y) in a regression analysis is called the ________.
c) dependent variable
If there are two variables and there is a linear correlation between them we try to find the regression line by using least squares method.
X the variable which is input or which is first found out is called independent variable.
The outcome variable is the dependent variable
Dummy variable is one which takes only values 0 or 1 depending on whether not present or present.
The formula for the volume of a sphere is (4/3)*pi*r^3. Using this formula, we have 44.6022 cm^3 = (4/3)*pi*r^3. Solving for r, we get 2.2 cm. Thus, the radius of the sphere with an approximate volume of 44.6022 cubic centimeters is 2.2 cm. To add, the volume of a sphere is also exactly two-thirds the volume of its circumscribed cylinder.
Answer:
Step-by-step explanation:
Keep in mind that to find the average they would do:
Average = Sum of students' ages / number of students
So to solve this question we should firstly find the sum of all their ages.
To do this you multiply 5 by 9 = 45.
This means 45 is the sum of all 5 students' ages.
Next you are given four students have ages 5 , 7 , 8 and 15.
The sum of their ages are: 5 + 7 + 8 + 15 = 35
This means that the final student has age 45 - 35 = 10 years.
