Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have 
ways to to choose 4 good components from 8.
We have 
ways to choose 4 components from a total of 9.
If all function properly then none is bad, we 
way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
Answer:
<h2>x = 5 , x = -3</h2>
Step-by-step explanation:
x^2 - 2x = 15
x^2 - 2x - 15 = 15 - 15 (Subtract 15 from both sides.)
x^2 - 2x -15 = 0 (Simplify.)

<em>Set up & solve for a quadratic formula</em>
<h3><em>* I will solve for your first x</em></h3>
2 + root 64 / 2x 1 = 2 + root 64 / 2
root 64 = 8
= 2 + 8 / 2
= 10 / 2
= 5
<em>To solve for the second, follow the same pattern/formula for the first that I used to get 5.</em>
To graph a situation that would involve a linear graph, first determine your x and y axes.
The x-axis will be the independent variable, one that does not change based on other variables. An example is time.
The y-axis, the dependent variable, depends on the independent variable.
The model equation for a linear line is y = mx + b.
"m" is the slope, and the "b" is the y-intercept (where the graph crosses the x-axis at x=0).
For example, a situtation could be that Joe starts with $10 in his account and adds $5 every day to his account.
The x-axis is time in days.
The y-axis is amount of money in his account.
The slope, or rate of change is 5.
The y-intercept, the amount of money he has at x=0 (0 days) is $10.
The equation would be y = 5x + 10
To draw this, plot the y-intercept at (0, 10), and the next point would be 5 units up and one unit to the right because the slope is 5, or 5/1 (remember slope is rise over run: "rise" up 5 and "over" to the right 1).
First off, we have to divide 100 by 10 to get 10%. That would be ten. So in conclusion, 10% of 100 is 10
