Answer:
The probability is 16%.
Step-by-step explanation:
Start by finding the multiples of 6 that are under 50.
6;12;18;24;30;36;42;48
There are 8. Now, we must divide 8 by 50. This is the chance that it will be a multiple of 6.
8/50
This simplifies even further, to 4/25.
We can write this as .16, or 16%.

Answer:
The rule is "Subtract 9"
n = 11
Step-by-step explanation:
To find the rule you have to find what's common with all of them. This requires a little bit of testing.
THINK
Do I divide by 10? No because it doesn't work for all of them.
Do I divide by 4? No because it doesn't work for all of them.
Do I subtract by 9? Yes because it works for all of them.
Rules can be a lot of things. Subtraction, multipilcation, division, addition, or with variables.
Answer:
x ∈ (-oo ; 3)
Step-by-step explanation:
4x - 7 < 5
4x < 5 + 7
4x < 12
x < 12 : 4
x < 3
x ∈ (-oo ; 3)
Step 1: Find the slope
Slope formula = (y2 - y1) / (x2 - x1)
---You can choose any two points when finding the slope!
Point 1 = (-2,-10)
Point 2 = (-1,-3)
Slope = (-3 - - 10) / (-1 - - 2)
Slope = 7 / 1
Slope = 7
Step 2: Find the y-intercept
Now that we have the slope, we'll plug that and one point into slope-intercept form. Then, we'll solve for b.
Slope-Intercept Form: y = mx + b
---m is the slope, b is the y-intercept
Point = (-1, -3)
Slope = 7
-3 = 7(-1) + b
-3 = -7 + b
b = 4
Step 3: Put it all together
Now that we know the slope and y-intercept, all that's left to do is plug them into slope-intercept form.
Slope-Intercept Form: y = mx + b
Slope = 7
Y-Intercept = 4
Line: y = 7x + 4
Correct Answer: A

The solution of the equation are as follows:
x = 6 and y = -5

<h3>How to solve the system of equation?</h3>
4x + 5y = -1
-5x - 8y = 10
Therefore,
20x + 25y = -5
-20x - 32y = 40
-7y = 35
y = -5
Hence,
4x + 5(-5) = -1
4x - 25 = -1
4x = -1 + 25
4x = 24
x = 24 / 4
x = 6
