<h2>
Answer:</h2>
The correct statement that is used when a scatter plot is constructed is:
The independent variable is the input variable and should be represented by the x-axis.
<h2>
Step-by-step explanation:</h2>
We know that while plotting a graph or a scatter plot the x-axis which is the horizontal axis of the plot represents the input value or the value of the independent variable and the output value i.e. the value of the function corresponding to the input value is represented by the y-axis.
As the value of the output is evaluated corresponding to the input value hence the variable y is also known as the dependent variable and is represented by the y-axis.
Answer:
The total number of students that ate lunch are 300 .
Step-by-step explanation:
Formula
As given
There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.
The percentage of students that chose salad is 15%.
If 45 students chose salad.
Here
Percentage = 15%
Part value = 45
Put in the formula
Therefore the total number of students that ate lunch are 300 .
Answer:
The graph is also attached.
Step-by-step explanation:
Given the expression
Apply absolute rule:
so the expression becomes
solving condition 1
x−3<5
Add 3 to both sides
x−3+3<5+3
x<8
solving condition 2
x−3>−5
Add 3 to both sides
x−3+3>−5+3
x>−2
combining the intervals
Merging overlapping intervals
Therefore,
The graph is also attached.
Answer:
114, and 115
Step-by-step explanation:
114+115 = 229
Answer:
3x - 8
Step-by-step explanation:
To find f(x + 1) substitute x = x + 1 into f(x)
f(x + 1) = 3(x + 1) - 7 = 3x + 3 - 7 = 3x - 4
Similarly
f(1) = 3(1) - 7 = 3 - 7 = - 4
Hence
f(x + 1) + f(1) = 3x - 4 - 4 = 3x - 8
