Can we see an attachment of the problem?
Answer:
The answer is 78%
Step-by-step explanation:
Step 1: The given regression equation y = -0.414x + 106.55
Step 2: The length of the film = 70 minutes
Step 3: Plug in x = 70 in the given equation and find the value of y.
y = -0.414 (70) + 106.55
y = -28.98 + 106.55
y = 77.57
Y = 78%
Hope you will understand. :)
<em>Note:</em>
<em>Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.</em>
Question 2
Answer:
The equation in the standard form is:
Please also check the attached graph.
Step-by-step explanation:
We know that the equation in the standard form is
Ax + By = C
where x and y are variables and A, B and C are constants
Given
To determine
- Write the equation in the standard form
We know that the slope-intercept form of the line equation

where
In our case:
substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation
y = mx+b
y = -2/3x + (-4)
y = -2/3x - 4
Writing the equation in the standard form
2/3x + y = -4
Therefore, the equation in the standard form is:
Please also check the attached graph.
Answer:
The fact that the expressions are equivalent means that for any value of the variables, the two expressions have the same solution.
