Two airlines each made 30 flights. The dot plots shown compare
how many minutes the actual arrival times were before or after
the scheduled arrival times of these flights.
Negative numbers represent the minutes the flight arrived before its scheduled time.
Positive numbers represent the minutes the flight arrived after its scheduled time.
Zero indicates the flight arrived at its scheduled time.

airline should you buy your ticket? Justify your response by addressing both the
measures of center and spread of the distributions.

Answer:
x = -9
Step-by-step explanation:
First, subtract 3 from both sides of the equation and distribute the 3 to the x and -2.
3x - 6 - 2x = -15
Now, add the 6 to both sides of the equation and combine 3x and -2x.
x = -9
The value of x is -9.

Step-by-step explanation:
During a 60-minute period, a traffic engineer counted 54 trucks and cars that crossed a bridge. The ratio of trucks to cars that travel across the bridge is usually 2:7. The equation LaTeX: \frac{2}{7}=\frac{t}{54-t}2 7 = t 54 − t can be used to predict the number of trucks, t, the engineer should have counted. How many trucks should the engineer have counted?
Answers
Answer:
Step-by-step explanation:
Given the expression for the equation representing the prediction of number of trucks as;
2/7 = t/54-t where t is the number of trucks
To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;
Given 2/7 = t/54-t
Cross multiply
2(54-t) = 7t
Open the parenthesis
2(54)-2t = 7t
108-2t = 7t
7t+2t = 108
9t = 108
Divide both sides by 9
9t/9 = 108/9
t = 21
Hence the engineers should have counted 21trucks
Which point is located on the line represented by
the equation y = 5x + 4?
Answers
All points in the format: (x, 5x + 4) are in the line.
A few examples are: [tex](-2,-6), (-1,-1), (0,4), (1,9), (2,14)[/tex]
--------------------------
The equation of the line is:
[tex]y = 5x + 4[/tex]
This means that the points located on the line have the following format:
[tex](x, y) = (x, 5x + 4)[/tex]
Among the examples:
[tex](-2, 5(-2) + 4) = (-2,-6)[/tex]
[tex](-1, 5(-1) + 4) = (-1,-1)[/tex]
[tex](0, 5(0) + 4) = (0,4)[/tex]
[tex](1, 5(1) + 4) = (1,9)[/tex]
[tex](2, 5(2) + 4) = (2,14)[/tex]
