Answer:
b = 12.5
Step-by-step explanation:
2=3.5(-3)+b
2=-10.5+b (you add 10.5 on both sides)
b= 12.5
I don't really get your question. But, I will try my best to answer it. 42 is a whole number and you could use the number for any operation.
I hope this helps:)
Answer:
B
Step-by-step explanation:
This is a neat question
f(x) - g(x) = 2x Add g(x) to both sides
f(x) = g(x) + 2x
Now you need the right hand side to have 20 added to g(x).
2x must = 20
2x = 20 Divide by 2
x = 20/2
x = 10
So the answer must be x = 10
y = -3/5(x-3)
y= (-3/5) x + 9/5
Step-by-step explanation:
Step 1 :
The equation of line in point and slope form is (y- y intercept) = m(x-x intercept)
Where m represents the slope and x1 and y1 are points on the line.
Given (-2,3) and (3,0) are points on the line
m = (y2-y1)/(x2-x1) = (0-3)/(3-(-2)) = -3/5
So the equation of the line in point slope form is
(y-0)= -3/5(x-3) = y = -3/5(x-3) [taking the point as (3,0)]
Step 2 :
The equation of a line in slope and intercept form is y = m x +c
m denotes the slope and the constant c denotes the y intercept (the value of intercept in the y axis when x = 0)
when x = 0, y = 9/5 [using the equation in step 1]
Hence the equation in slope and intercept form is
y= (-3/5) x + 9/5
Answer:
The given statement is true.
Step-by-step explanation:
Regression Analysis:
- Regression analysis is a technique that help us to find or define a relationship between a dependent and an independent variable.
- It helps us to predict the dependent variables with the help of independent variables.
- Various techniques are used for the prediction of independent variable.
- It is a type of predictive statistical technique and helps us to find whether there is a significant relationship between the dependent and the independent variable.
Correlation analysis:
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- It is not necessary that the that out of the two variable one needs to be dependent and the other to be independent.
- Correlation can be positive, negative or zero correlation.
Thus, the given statement is true.
