Answer:
a^2+b^2=c^2
Step-by-step explanation:
You can apply this formula to any quadratic equation.
Answer:
X = 28
Step-by-step explanation:
The angle is 90 degrees in total and one portion of the angle is 62 degrees
You subtract the 62 degrees from the 90-degree angle to figure out the other unknown portion of the angle
90 - 62 = 28
The correlation coefficient r of the data set is <em>-0.28</em>
X = first number
x - 8 = 2nd number
5x = 3rd number
x + x - 8 + 5x = 69
7x - 8 = 69 <=== this is the equation u would use
7x - 8 = 69
7x = 69 + 8
7x = 77
x = 11
1st number = 11
2nd number : x - 8 = 11 - 8 = 3
3rd number : 5x = 5(11) = 55
Answer: -3.3%
By not knowing how i did it, means you will still not know how to do it next time you encounter a similar problem.
Knowing how to solve a problem is just as important or even more important than just knowing the solution.
