-2 is the answer because you do the change of y over the change of x.
<u>Answer:</u>
3%
<u>Step-by-step explanation:</u>
We are given the data of number of cars observed waiting in line at the beginning of 2 minute intervals between 3 and 5 p.m. on Friday.
We are to find the probability (in percent) that there is no one in line.
Sum of frequencies = 2 + 9 + 16 + 12 + 8 + 6 + 4 + 2 + 1 = 60
Frequency of no car in line = 2
P (no car in line) = 2 / 60 × 100 = 3.3% ≈ 3%
The solution to the system of equation is (3/2, -1/2)
<h3>System of equations</h3>
Given the following system of equations as shown;
(3x+y=4 .... * 4
2x-4y=5 ..... * 1
_______________
12x+4y=16
2x-4y=5
Add both equations
12x+2x = 16 + 5
14x = 21
x = 3/2
Substitute x = 3/2 into any of the equation to have;
2x-4y=5
2(3/2) - 4y = 5
3 - 4y = 5
-4y = 5 - 3
-4y = 2
y = -1/2
Hence the solution to the system of equation is (3/2, -1/2)

Answer:
r = 1
Step-by-step explanation:
We know that x and y are proportional, with the the equation y = rx representing the proportional relationship. Where r = constant of proportionality
Thus the constant of proportionality would be:
r = y/x
Using any of the given pair of values from the table, say (5.8, 5.8),
r = 5.8/5.8
r = 1
