Step-by-step explanation:
Given
If x = 4 Then
3x + 1 = 3 * 4 +1 = 12 + 1 = 13
The answer should be 13.
Answer:
1.5
Step-by-step explanation:
Attached to this answer is the diagram of the box plot described in the question, and the means from the plot are calculated thus;
Students; no. of siblings
student 0 2
student 1 4
student 2 7
student 3 5
student 4 2
Total 20
Mean no. of siblings = (total number of siblings) ÷ (total number of students)
Note that number of students here are the once that had at least one sibling, others without siblings are not used in the calculation, hence 5 students (student-0 to student-4) make up total number of students, while the remaining 4 students (student-4 to student-9) are disregarded.
Therefore, mean = 20 ÷ 5 = 4 siblings.
Answer:
Step-by-step explanation:
The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'
At first, let's take the unknown number as 'x' . (asked in the question).
So, the number we think about = x
Now, we need to multiply it by 3. So,
In the next part, we need to add 4 to it so,
Now, by squaring the result, we'll get the expression as,

The estimated regression equation is Price = bo +b1Age+ b2Mileage + b3Cylinders
<h3>How to determine the regression equation?</h3>
We have:
- Predictor variables = 3
- Variable 1 = Age
- Variable 2 = Mileage
- Variable 3 = Cylinders
The regression equation is estimated using:
Price = bo +b1 * Variable 1+ b2 * Variable 2 + b3 * Variable 3
Substitute the variable parameters
Price = bo +b1Age+ b2Mileage + b3Cylinders
Hence, the estimated regression equation is Price = bo +b1Age+ b2Mileage + b3Cylinders

Hi Dez123,
Graph the system of equations. {−x+2y=−8 3x−y=−6
−y= −3x + 8
6x − 2y = 8
Multiply y = 3x − 8 by -1
y = 3x − 8
6x − 2y = 8
y = 3x − 8
−2y = −6x + 8
y = 3x − 8
y = 3x − 4
The graph is in the picture below!
Hope This Helps!
