Step-by-step explanation:
The question is incomplete, as the required lengths are not given.
I will use the following data set to answer the question.
First, is to determine the range of the dataset
Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval
<em>So, we use 4 classes</em>
Plot the frequency distribution table as follows:

Answer:
y=2x+15
Step-by-step explanation:
Add 2x to both sides of the equation.
First let's get rid of the x by multiplying the tip equation by -2
-2 (-6x - 2y = -4)
+
(-12x - 5y = -13)
Distribute
(12x + 4y = 8)
+
(-12x - 5y = -13)
x cancels out and you're left with
-1y = -5
y = 5
Now solving for x, plug in your y into one of the equations
-6x - 2(5) = -4
-6x - 10 = -4
-6x = 6
x = -1
(-1 , 5) is the solution
Answer:
Step-by-step explanation:
7x - 1 + 3x - 9 = 180
10x - 10 = 180
10x = 190
x = 19
7(19) - 1 = 133 - 1 = 132
3(19) - 9 = 57 - 9 = 46
Answer:
Slope = 7
Y-intercept = 4
Step-by-step explanation:
the equation follows the formula of y=mx+b
m = slope
b = y-intercept
